Electricity is becoming expensive with each passing day and more people are getting interested in using solar energy to meet their electricity needs. Power cuts and dependence on DG sets is making people look for more and better sources. Solar PV panels provide a very good alternative. Ministry of New and Renewable Energy (MNRE), Government of India is also promoting solar PV systems under the Jawaharlal Nehru National Solar Mission in the country. They also provide a subsidy to people buying solar panels under this scheme. There are a lot of people keen to buy solar panels in India so we thought of doing a research on the price of solar panels.
- As per our research and resources from the solar PV industry, cost of a PV module (just the panel) costs anywhere between Rs 30 to Rs 50 per watt of power generated (depending on the quantity you are buying).
- The modules having higher Watt power capacity are cheaper per Wp as compared to modules with lower Watt power capacity. The efficiency of solar panels is also better for modules of higher Watt power as compared to modules of lower Watt power.
- There is not much difference in price between imported and Indian solar panels. But if you are looking for a subsidy, then the only option that you have is to go for Made in India panels.
- If you are living in an area where power cuts are less frequent and you want to implement solar PV system to reduce your electricity bills then the best solution would be to go for a Grid Connected Solar PV System. It will cost you anywhere between 60,000-90,000 per kWp (cost varies based on the type of inverter and panels you choose).
- If you are living in an area where there are frequent power cuts, then the best solution for you would be to go for an “Off Grid” Solar PV System. Off Grid Solar PV system will include batteries, which are an expensive part of the system and these would need replacement every few years (4-7 years). A typical Off Grid Solar PV System would cost about Rs 1-1.25 lakhs.
- There are two types of Solar PV Cells: Monocrystalline and Polycrystalline. The difference between the two is that Monocrystalline is made of single silicon crystal whereas Multi-crystalline PV is made up of multiple crystals. A monocrystalline is more efficient in converting solar energy into electricity per sq meter area than a multi-crystalline PV. Thus the space required for the same amount of wattage is less in monocrystalline PV panel. Thus it is costlier than a Multi-crystalline PV. The modules available in India are mostly “Polycrystalline”.
- Typical efficiency of panels available in India is between 14-17% against China made solar panels which have an efficiency of less than 11%. Please note that lower the efficiency, more panels you would need to get the same amount of electricity and it will occupy more rooftop area.
