Many businesses and households are now switching to solar panels. They are now realizing cost-effectiveness and environment friendliness of solar
As the world is waking up to the endless benefits of renewable energy over conventional energy sources, there has been a sharp spike in solar projects that
Self-sufficiency in energy is crucial for any country when it comes to socio-economic development. India’s rapid industrialization and modernization has fuelled economic growth, which has put tremendous pressure on the nation’s energy demand
Rapid modernization and industrialization has put tremendous pressure on India’s energy demands. Even where this demand is met, there are unprecedented levels of Green House Gas emissions that are irreversibly damaging our ecosystem.
We all know how extensive usage of fossil fuels is leading to global warming in an alarming way. It has made it imperative for us to come up with sustainable solutions that are minimum on carbon footprint and greenhouse emissions.
Solar LED street lights are quickly gaining immense popularity across the world. Not just Solar Lights in Gurgaon, whichare affordable mediums of lighting the streets, however, they are additionally economical and environmentally-friendly.
Solar energy or energy through the sun is actually a blessing in a scenario when energy resources are depleting day by day. Solar energy is not only a powerhouse for industrial setups, but it also powers residential setups in an effective manner too.
The dream of a ‘New India’ includes a lion's share of clean energy. The government has a renewable energy generation target of 175 GW by the end of 2022. The target includes 5 GW from small hydropower, 10 GW from bio-power, 60 GW from wind and 100 GW from solar power
The Group of Twenty (G20) is an international forum whose members include 19 countries and the European Union. The G20 economies collectively account for around 90 per cent of the gross world product (GWP), 80 per cent of world trade, two-thirds of the world
LED Lighting is the future of lighting, these new eco-friendly light bulbs save both money and energy. A typical bulb lasts around 50,000 hours of continuous operation, that’s over 17 years if used for 8 hours every day! All are speaking the same language about Solar Lights in Gurgaon. They can also reduce lighting bill by up to 90 per cent.
Power cut is an issue that each one of us has been affected by. In tier 2 and 3 areas, there is a problem of frequent power-cuts. One of the many reasons is uneven power distribution and excessive load on the grids, causing regular power cuts. It is the end user who has to bear the brunt and has to decide on an alternative. Inverters are a preferred option by most people who make up for frequent power cuts.
Using solar inverters is increasingly becoming a better option to combat the issue of electricity. These inverters are charged by the energy generated by the sun and are great in reducing running electricity charges on a regular basis.
It is an essential element of solar power set up for homes. It changes the Direct Current (DC) to the Alternating Current (AC). Without this, the solar power system will not have the capacity to light the entire houses.
There are different types of solar inverters available in the market:
▪ Sine Wave Inverter:
These solar inverters generate sine waves for which the majority of the appliances are designed. Most of the appliances can run safely and effectively on these types.
▪ Square Wave Inverter:
It is commonly known as a Digital Inverter. It generates the square wave AC output that isn’t sufficient for all types of home appliances as the appliances are suitable for sine wave AC pattern only. This type of inverter is not recommended for homes as not all devices can be supported by it.
▪ Stepped Sine Wave Inverter:
It falls between the above two types of inverters. It is not widely available in the market. It is a type of low-cost inverter and mostly suitable for electronic gadgets.
Before purchasing an inverter it is advisable to calculate the power requirements. Normal inverters can be ideal for using fans and lights. However, the heaviest battery inverters can also support AC and TV as they require a heavy load. In such cases, inverters with high capacity solar panels are an ideal choice. Solar energy inverters are highly efficient when operating on high load.
▪ Size of the inverter: The inverter should be able to handle maximum power that the solar system can generate efficiently and effectively. If one requires a 5kW solar power system, they need a 5kW panel and inverter to be able to handle it.
▪ Weatherproof: Not all solar inverters are weatherproof and may require an extra weatherproof cage, which comes at an additional cost.
▪ Warranty: Mostly solar inverters have a warranty of 5 to 12 years. Longer the warranty, more the protection.
Since the price of solar equipment has dropped significantly in the last five years, it is advisable to switch to solar inverters. With the advancement in technology, the performance of the solar panels is highly efficient, leading to a reduction in costs.
“I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait till oil and coal run out before we tackle that. I wish I had more years left!”- Thomas A. Edison
The Union Government’s ambitious National Solar Mission of meeting 175 Gigawatts (GW) Renewable Energy(RE) capacity by 2022 would give a boost to the solar energy industry in India. Out of the total 175 GW of RE produced, 100 GW would be from solar power, remaining from hydro, rooftop and bio means.
India has an enormous potential of becoming the largest producer of solar energy in the world. The geographical location can owe to becoming one. India is near to the equator. The eastern states of India- Rajasthan, Andhra Pradesh, Gujarat, Madhya Pradesh, Punjab, Haryana, and Maharashtra, have a suitable tropical climate to harness the solar power to its full capacity.
There has been a significant improvement in solar-generation capacity from 2014 to 2018. It grew eight times from 2,650 MW on 26 May 2014 to over 20 GW as on 31 January 2018. India's solar installed capacity reached 26 GW as on 30 September 2018. It has been able to make a considerable difference in solar power capacity due to the financial support by multinational investment banks, initiatives by Govt. of India and state level progresses. State-level progress has happened in the large Indian states along with the eastern states of India. Karnataka topped all the solar state in the FY 2017-2018, with the installed capacity of 600 MW at “Pavagada Solar Park” and the 2,000 MW (2GW alone) solar project to get fixed by the end of the year 2020. After Karnataka, Telangana and Andhra Pradesh were the leading states that year.
Below is the list of Government initiatives that have helped in the scale-up of the solar capacity since 2014:
- The Union Cabinet approved raising funds through bonds issued by the Indian Renewable Energy Development Agency (IREDA) and Greenko for renewable energy projects. - Union Government’s decision to provide custom and excise duty benefits to the solar rooftop sectors also catalyzed the progress. - The Ministry of New and Renewable Energy (MNRE) has been implementing programmes such as National Biogas and Manure Management Programme (NBMMP), Biogas Power (Off-grid) Generation Programme (BPGP), and Waste to Energy Programme for setting up of Biogas Plants to fulfill the needs of people from remote areas.
Below is the list of financial support provided by International financial institutions:
- European Investment Bank (EIB) with YES bank financed a total loan amount of US$ 400 million for solar and wind projects in India. - EIB also extended a loan amount of US$214m to State Bank of India (SBI) for five grid-scale solar energy projects. These projects are due by 2020. - International financial institution World Bank approved US$ 100 million in the year 2017 for large-scale solar parks in India. - The World Bank also signed an agreement with the International Solar Alliance(ISA) to support India in its ambitious target. “India’s power system is among the largest in the world.”- remarked by World Bank
Alongside, there are economic factors if overlooked; the target might fall behind. As per the latest report by rating agency CRISIL, India still falls short by five times in achieving its goal of 100 GW solar power by 2022. It would be able to touch 78-80 GW solar power capacity against 20 GW (as on 31st Jan 2018), by fiscal 2023.
There has been an ongoing discussion on the imposition of safeguard duty on solar panels and modules. About 90% of the solar modules used in India get imported from China and Malaysia. So, 25% of safeguard duty imposition slowed down the overall project’s progress. It also impacted the outcome of bid price leading to cancellations of bidding tenders. Uttar Pradesh canceled an auction for 1000 MW solar project in July 2018 when the lowest bid came at 3.48/- per unit. Solar Energy Corp. of India (SECI) also canceled 950 MW of solar tenders due to the same reason. The solar power tariffs had gone down to 2.44/- per unit in 2017 which was threatening for domestic manufacturers of solar modules. So, Govt. decided on safeguard duty imposition. But this had led to cancellations of indispensable auctions. Later, Govt. lifted the safeguard duty which made the domestic manufacturers unhappy again.
According to Rahul Prithiani, director of CRISIL Research, Government should offer an incentive to help individual state project’s sustainability. It should also take each solar project bids more carefully and live with the bid price even if the tariffs are towards the higher side. Otherwise, the chances are India would miss upon the ambitious target of generating 100 GW solar power by 2022.
There is an array of solar modules available in the market today. However, not all models may be suitable for everyone. There are many factors to consider before zeroing in on the one that suits your needs best. Here is a list of various solar modules available today:
● Crystalline Silicon
The majority of the photovoltaic (PV) of the world are based on silicon. The substance is used in PV is different based on the purity. Better the aligned silicon, better and purer will they be. The better alignment will lead to better conversion of the solar energy into electricity.
The efficiency of the silicon is directly impacted by its purity. However, it is an expensive process to make silicon pure. For most people, it is not efficiency, but the cost and space factors that are important.
Solar cells that are made of the monocrystalline silicon are quite easily identifiable by its look. It is uniform and high purity silicon. The four sides of monocrystalline cylinders are cut to optimize its performance and lower the costs giving it its characteristic look.
● They are high in efficiency owing to the purity of the highest grade of silicon. It is generally 15-20% efficient.
● They are very efficient in small spaces. They produce more than four times the electricity than the thin film solar panels.
● They have the longest life amongst all solar panels. Manufacturers typically offer a 25-year warranty on such solar panels.
● Perform better in the low light areas.
● They are the most expensive solar panels.
● The entire circuit can break down if the panel is covered with snow or dirt even partially.
● Due to cutting of the sides, it results in a large amount of silicon being wasted.
It is the first type of the solar panels based on the polycrystalline silicon. It is made by melting and pouring raw silicon in square molds. It is then cooled and cut into perfect square shaped wafers.
● It is a simple and cost effective process to make polycrystalline.
● Lesser wastage in comparison to the monocrystalline.
● Efficient for homes.
● Owing to the lower purity, they have less efficiency, which is reduced to 13-16 per cent. Therefore, they are not as efficient as the monocrystalline solar panels.
● They require large surfaces, therefore lower efficiency of space.
String Ribbon solar modules are made from polycrystalline silicon. String Ribbon is a type of a manufacturing technology that is used to produce a form of polycrystalline silicon.
● Its manufacturing requires half the amount of silicon than monocrystalline manufacturing.
● It consumes more energy and is costly and extensive.
● They have lowest space-efficiency.
Thin film solar cells are manufactured by depositing a single or many thin layers of the photovoltaic material in substrates. The various thin film solar cells are listed below:
● Amorphous Silicon (a-Si)
● Cadmium Telluride (CdTe)
● Copper Indium Gallium Selenide (CIS/CIGS)
● Organic Photovoltaic Cells (OPC)
● It is simple to produce these in bulk.
● They are comparatively cheap to produce.
● They look appealing due to the homogenous look.
● Higher temperatures and shade have a lower impact on such solar modules.
● In large spaces, these panels work excellently.
● They are cheaper but require large spaces.
● Not useful for residential purposes.
● They degrade faster and have a shorter warranty period.
Building integrated Photovoltaics have multiple subtypes or methods of integrating it. These can be based on either crystalline or both on crystalline and thin film solar cells.
Building integrated photovoltaics may be for roofs, walls, facades, windows and many that can be made by combining photovoltaic material. People can also look to integrate photovoltaic in their entire homes. Howver, it is considered expensive for most home-owners.
It is ideal to get the space evaluated by the experts to install the best suitable type of solar panel. Some of the scenarios in the home front are as follows:
For homes where space is a constraint, thin film solar panels are an ideal option. Crystalline based solar modules are also preferred if one wants to limit the space in the PV system. However, not many manufacturers provide thin film solar panels for home spaces currently.
Mono and Polycrystalline solar panels are great choices offering same advantages. The polycrystalline solar panels are less on the space efficiency where as the monocrystalline solar modules are known for a higher level of electrical power production. It is best to evaluate all these factors before deciding on installing solar panels.
Monocrystalline solar panels are high in cost and efficient for small spaces.
If one is considering the lowest cost solar panels, they should consider installing thin film solar panels. They are the best choice in solar panels when it comes to cost effectiveness.
The working principle of a solar PV module is harnessing radiant heat and light energy from the sun and converting that energy into electrical energy using photovoltaic effect.
A basic solar PV system consists of 4 essential components:
1) PV cells- It is the smallest unit of a solar PV system.
2) Solar PV modules- Several PV cells wired either in series or parallel interconnection, encapsulated with a transparent material (mostly tempered glass) on the front side and protective waterproof covering on the rear side make a solar PV module.
3) PV panels: a group of PV modules assembled makes a PV panel.
4) PV arrays: a solar PV array consists of groups of PV modules and panels connected to form a complete power-generating unit. A single PV cell produces a tiny amount of electric power, which is around 1 watt to 2 watts. This amount is too low for practical applications. So, the connection assembly has several (usually 36 PV cells) solar PV cells:
a) wired in “parallel” interconnection to produce a higher electric current, or
) wired in “series” to produce a higher voltage.
A solar PV module traps the solar energy; converts this energy into direct current (“DC”) electricity. A PV inverter converts this DC into an alternating current (“AC”) electricity for its end-use application.
PV cells are made up of light semiconductor materials. Based on the production technologies for PV modules, there are broadly two categories.
A) Crystalline Silicon: Crystalline cells made up of pure silicon wafers which are 150-200 microns thick.
1) Monocrystalline Silicon (Si)
2) Polycrystalline Silicon (Si)
B) Thin Film(Amorphous): Layers of semiconductor material (0.3 – 2 mm) deposited on the glass or stainless steel make a thin film solar cell
|Monocrystalline Si||Polycrystalline Si||Thin Film (Amorphous)|
|Module efficiency||15%-20% (highest)||13%-16%||6%-8% (lower)|
|Warranty period||25 years||25 years||15-25 years|
|Estimated cost per Watt(W)||60-65 (high)||50-55 (medium)||35-40 (low)|
|Temperature coefficient (%/°C)||-0.4 to -0.5||-0.5||-0.21|
Important factors, which affect a PV module efficiency:
a) Solar irradiance: The current produced in a solar panel is directly proportional to the amount of solar energy received.
b) Ambient temperature: Voltage generated in a solar panel will be less if the ambient temperature is high.
c) Effect of insolation: If insolation is less than the amperage is also low while the voltage remains almost constant.
Hence, a solar PV module expressed under three testing conditions known as Standard Test Condition (STC): (1) 1000 W/m² of sunlight (2) 25°C ambient cell temperature (3) spectrum at air mass of 1.5, helps in determining the output. 1-kilowatt peak module is capable of producing 1 kilowatt of power (1kWH) at STC. But it is difficult to produce ideal solar output. Usually, the solar panel output expected is labelled by the manufacturers at the back side of a PV module.
Solar PVs has multi-varied applications from lightening up the household appliances to spacecraft propulsion. Below is the list of few of latest ones:
1) Utility interactive applications: Most solar PVs are installed on the rooftop or mounted on the ground of the buildings as per the space availability. In a grid-connected solar PV configuration, the building has two parallel power supplies. One from the solar PV setup and the other from the Power Grid station. At daytime, when there is a supply of solar energy, the building has the electricity supply from the Solar PV. When there is no or insufficient supply of solar energy to produce PV electricity, then the required electricity supply is fulfilled from the supply by power grid station.
2) Electricity in the remote areas: The other type of setup is Off-grid solar PV setup, done in the rural areas, construction sites or off-shore islands where the power grid stations are far away and tapping the electricity is difficult.
3) As roof tiles: Solar PV technology in solar roof tiles are replacing the conventional tiles in Europe as they are cheaper, only the one-time installation cost is higher, but the resale value of the building increases. It is soon to find its way in the US.
4) Portable device charging: As the number of personal electronic gadgets are increasing so are the means of charging facility increasing. Solar power chargers working on the principle of Solar PV technology are now available in the market that can charge for mobile devices at one time.
5) Electric car-battery charging: With the increasing number of electric cars on roads, and considering the duration of time the cars are parked outside in the sun, charging of electric car batteries can happen by solar PVs panelled on the roof of the electric car bodies.
Conclusion: Solar PV technology is finding broad applications for the reason that PV modules degrade slowly and are reliable. They are fossil-fuel free, and no greenhouse gas emissions happen, thereby making it environment-friendly. One-time installation might be a costly affair, but it comes with many financial incentives such as saving from utility rate hikes, price fluctuations in energy prices, the increase in the property resale value.
Solar energy is undoubtedly the most efficient and environment-friendly sources of energy today. However, some people are reluctant to switch to this sustainable source of energy because of number of myths that surround it. Here are some of the commonest ones; and the actual truth behind them:
1. Solar panels do not work in snow, rain or cloudy weather: One of the most prevalent myths related to the solar panels is that it does not work when it is snowing, raining or when it is cloudy. This is baseless as solar panels work just as effectively in low temperatures as in higher ones. The technology on which the solar panels are built works equally well in all weathers without any obstruction. Germany is the world leader in solar panels; and also a place where the temperatures regularly drop below zero. However, solar paneling works equally efficiently in all weathers.
2. Solar energy is a costly affair: Most people consider solar panels to be a high-cost proposition. However, this doesn’t hold true in the present-day scenario. The average cost of installing solar panels has fallen by 30 per cent in the last 4-5 years. Installing solar panels starts saving on electricity charges from the word go. It is cheaper to produce electricity from solar panels than from coal. In the long run, these savings add up to a significant monetary benefit.
3. Installing solar panels is complicated and requires a lot of maintenance: On the contrary, installing solar panels is straightforward when done by a trustworthy manufacturer. It gets even easier to maintain these panels if the connection is done from the utility grid. Maintenance is as simple as cleaning the collected dust or debris by water, which may collect over time.
4. Solar panels will damage the roofs: They actually preserve and protect the roof by covering the portion on which it is installed. As the panels are not directly attached to the roof, they can be removed anytime if the roof from a spot needs repairing of any kind. They are just mounted on the roofs. If there are any gaps between the panels and the roofs, they can be joined simply by using a sealant. One should always make sure the roof is completely damage-free before installing the panels.
5. Solar panels are based on the size of your home: Solar panels are customized and designed as per the size of the roof and the slope. The cost of the panel is determined by considering the size available. The entire area available along with the sides is taken into account when deciding on the paneling. The space where the panel is to be installed should not have obstructed sunlight. That’s all!
We are well aware that the energy provided by the sun has no limits. However, we have tapped only a fraction of this energy source. With passing time, and as the population and energy needs are growing day by day, we need to look for cleaner, renewable and better sources of energy. What better choice than solar energy!
Amongst other industries, solar energy has impacted these three base industries significantly.
Solar technology is being widely accepted in the agriculture sector. The use of solar PV and solar thermal technologies can be used in a variety of forms in the farming sector. One of the most common uses of the solar technology in this sector is by installing solar modules on the roofs of the barns of buildings to generate heat and electricity. Another common application of solar technology is for water pumping.
Solar panels are successfully being used to power irrigation. Solar dehydrators are yet another solar technology that is being used effectively. In solar dehydrators, the solar radiations are being used to dry the grains and crops quickly than leaving them in the sun after harvesting.
Solar energy power plants are beneficial for the environment as they do not generate water pollution, air pollution or any green house emissions. With a constant increase in the need of power, sources of new and unused sources are yet to reach their full potential. One can also not ignore the savings on cost in the long term by using solar power.
The construction of solar panels and modules on huge areas of land requires cleaning and grading. It leads to soil compaction and alteration of the drainage channels and may also lead to increased erosion. The central tower panels need water for cooling, which is a scarce resource arid areas. The rising water demand may put pressure on the available sources of water, which may lead to chemical spills. It may also lead to contamination of ground water or the ground surface.
Like homes have 360-degree solutions, transport too is utilizing solar energy fully! There are solar cars that use energy produced from the sun by converting it to electricity for electric cars charging. Solar cars make use of the photovoltaic cells to convert the available sunlight to energy. These are made using semiconductors that absorb sunlight mostly silicon. Silicon absorbs light to a much higher content. The energy generated from the sun frees electrons present in the semiconductors leading to the flow of electrons. The flow then leads to generation of the electricity that produces power in the battery and the specific motor present in the solar cars.
Solar powered cars have some excellent benefits. These cars have zero noise and air pollution. They are environment friendly and do not lead to the generation of the greenhouse gases.
Installing solar panels have become increasingly popular in the country. They are becoming a common choice for generating electricity in offices, factories and even homes. People are readily replacing the common electricity meters by installing PV solar panels.
The popularity of these units can be largely attributed to a reduction in costs and high efficiency. Also, a wide variety of solar products serve a wide spectrum of clients and their needs.
Solar Panels: In India, solar panels are available in film and crystalline varieties. Most of the solar panels in India are mostly imported from the other parts of the world and only some of them are domestically manufactured. The solar panels manufactured in the country are comparable in quality and pricing to their global counterparts.
● Solar Cookers: Solar Cookers are one of the most efficient solar products available, but they are not as common as other solar products. It is highly beneficial to use solar products in countries like India where there is a lot of sunlight and where high cost, environment-polluting fuel is used for cooking proposes. India has installed the world’s largest solar cooker at Shirdi, which is worth $280,000. The government also provides subsidies to this plant. It generates 3500kg of steam every day preparing food for 20,000 people. These cookers can be easily installed and maintained and save a huge amount of fuel costs.
● Solar Water Heaters: These are one of the most successful running solar products in India. Solar water heaters are quite easy to build and can simply be installed in homes or commercial setups.
● Solar Lighting: This phenomenon is growing at an incredible speed in India. It saves on high running costs and is environment-friendly. It is gaining popularity across segments and industries. Solar lights are being increasingly used in parks where they utilize the sunlight during the day and provide light by the night. Types if solar lightings are as follows:
1. Solar Lamps: They are not only known for their low operational cost but also their environment-friendly characteristics. They are widely used in areas where power cuts are a regular issue. They are an ideal solution in the rural areas in replacement to the high-cost kerosene and gas lamps.
2. Solar Home Lighting: It consists of mountain structures, solar panels, solar charging controllers, battery boxes. Fans and lights in the homes can also run solar home lighting systems.
3. Solar Street Lighting: These are used for lighting the streets at night. They are not connecting to any types of grids but are a stand-alone structure. The system is controlled by an in-built On-Off switch that operates and controls the light from the dusk till the morning hours.
4. Solar LED lighting: These lights are gaining popularity owing to the reduced costs. They are an effective alternative to the regular lightings.
● Solar Inverter: One of the increasingly common solar products is a solar inverter. It is not very high in prices and has a longer shelf life.
We, as a country, are likely to face many challenges in terms of environment and energy in the years to come. To successfully overcome such obstacles, India needs to adapt to an environment-friendly sources of energy.
There is a major requirement of shifting to renewable sources of energy from the conventional fossil fuels. It will help to reduce the emissions of the greenhouse gases, resulting in a positive impact on climate change.
There is a huge requirement for energy, which is increasing day by day. It is getting too difficult to meet the requirements through conventional means of generating power. With over 40 per cent of rural households in India without electricity, it is a matter of great concern.
There are constant efforts being made by the government to meet the environment-friendly energy needs. However, there is a need for the betterment and quicker adoption of the change. The Jawaharlal Nehru National Solar Mission (JNNSM) in 2009 was a major step that targeted 10 per cent of the solar energy in the country. The amount is way too less than what is required. JNNSM needs to work in a better and an efficient way in order to increase the solar energy production on India.
Nationwide solar initiative is required. India needs to deploy at least 100 million solar roofs and solar power generation tools within the next 20 years. By achieving such a target, India could be among the leaders in the solar energy across the world.
● Speed up the deployment of large-scale solar energy power plants. The government needs to set up a high target to set up as many solar plants as possible for the coming 20 years in order to bring about a major change.
● Set a National Renewable Energy Policy to create demand, industries and innovation related to green jobs.
● Formulate government policies to aid in the start-up capital promoting in the creation of renewable energy. A special fund needs to be assigned for the renewable sources of energy.
● The government should rule out all the subsidies on the conventional sources of energy.
● Encourage the states and major companies to invest in the cost-effective energy production.
● A move to electrify transportation should be made. Hybrid vehicles should be promoted and should be subsidized. Nationwide charging panels of electric cars from solar roofs should be started. Numerous solar charging panels like these could begin the much-needed green revolution in the country. The charging panels could be assigned at highly populated areas like the shopping malls, parks, hotels, etc.
● Large scale solar manufacturing plants should be manufactured in India. Solar and wind generation in parks and farms started. R&D should be conducted within the private institutions, and government entities.
All such steps, if incorporated effectively will lead to a change in the environment. Slowly but surely, together India can adopt environment friendly methods to building a better future.
India is an agrarian economy. It means that majority of its population survives on agriculture. With advancement in technology and changing times, the traditional sources of energy in the agriculture industry are being interchanged with new ones. Solar energy is a widely accepted source of energy, owing to cost effectiveness as the primary reason.
The rising fossil fuel prices restrict the agriculture sector in developing countries. Solar pumps are great in improving the cultivation and reduction of usage of diesel fuel significantly.
The cost of energy used to pump water can go up to 30 per cent of the total expenditure cost for farmers. Therefore, switching to solar pumps will not only be cheaper but also more convenient for the farmers. Using solar pumps, farmers can save on their electricity and diesel expenses by approximately $6biilion a year.
As solar energy is environment friendly, it is a great alternative and should be encouraged in all sectors, agriculture being a prime one. Solar pumps can play a major role in agriculture and its ancillary industries.
Owing to the benefits of solar pumps, India has announced the target of installation of 1 million solar pumps by year 2021.
The Indian government has announced the introduction of various business models involving solar irrigation pumps. The government is providing great subsidies along with 30 per cent capital subsidy on solar pumps to farmers. Some of the other facilities provided by the government are as follows:
● Accessing the pump by a group: In such a model, the pump can be purchased by a group of people. Here the financial cost can be borne by the group without causing a great financial burden on an individual. Each member of the group has an access to the pump when required.
● Renting: The farmers can rent a pump from the companies whenever required. It saves on maintenance and storage expenses.
● Pay as you go: In this facility, the farmers can pay for the pump in installments. By this facility, only a small amount goes at the time of purchasing the pump.
The government of India is trying to get as many farmers to switch to solar pumps as possible. Rajasthan has announced an additional 56% subsidy over the MNRE subsidy. Andhra Pradesh has also shown a tremendous number of installations of solar pumps with installation of more than 6000 pumps. States like Gujarat, Rajasthan, Karnataka, Tamil Nadu, Uttar Pradesh and Madhya Pradesh have shown increased number of installation of solar pumps recently.
● Financial problems, delay of subsidy reimbursement and low awareness rate are some of the major challenges in the installation of the solar pumps.
● Confusion regarding operation and maintenance of the solar pumps is another big issue.
The increase in the usage of solar pumps can strengthen the overall socio-economic structure in the country. Along with many benefits to farmers, it can also help in promoting a clean, green and a beautiful environment.
Solar energy is a growing phenomenon on the domestic as well as the commercial front. However, as much as people are realizing the benefits of switching over to solar energy, it is still not widely adopted as it should be. There are numerous direct and indirect benefits of switching to endless source of energy. Some of the benefits are stated as follows:
1. Beneficial for the environment: One of the widely known facts is that solar energy is great for the environment and enough has been said about it already. Using solar energy is a great way to reduce the carbon footprint. Solar power doesn’t require any resources except water for functioning. It doesn’t emit any form of greenhouse gasses and hence does not pollute the environment in any way. It is an easy way to a sustainable future.
2. Reduction in the electricity loss: Usage of electricity requires it to be transported from huge power plants to the consumers through widespread extended networks. Transmission of electricity through such long distances causes a significant amount of power loss. The benefit of using solar panels is that they get all their energy from the sun and are transported from the rooftop to the homes. There is no loss in energy as the electricity generation becomes domestic. One can easily control their bills and the total energy usage. Solar panels are durable and minimize the chances of interruption in the service provided.
3. Solar energy slows down the global warming : Installation of pv solar panels causes the global warming to slow down. According to the research conducted on global warming, installing of the solar panels on the roofs of homes and offices can help slowing down the phenomenon. Solar energy is considered the most environment friendly method of generating electricity in comparison to wind farms and other eco-friendly methods.
4. Free Source of Energy: Solar energy does not require any special source of energy other than the sun. Sun provides us with more than enough light, more than we can actually even utilize. Utilizing a solar panel saves on money from the very first usage. The savings can be measured in the long run. Longer a pv solar panel is installed, more benefits it is likely to give.
5. Optimization of underutilized land: Solar farms can be made out of land that has been declared unfit for other purposes. Any land that is not in an ideal location or perhaps is unfit for other purposes like agriculture, can be very well utilized for installing pvc solar panels.
