India is rich in solar energy resource and is densely populated, which provides the right opportunity for solar energy sector to proliferate. The support from the government has facilitated the growth of solar PV market in India (Please read The solar PV growth in India).
We have learnt that solar insolation values are very important in designing and sizing the solar panels (Please read "What is the average cost of solar roof in India?"). The high level of insolation saves you money and can make the system financially feasible while on other hand low level of insolation can increase the overall cost of your solar PV system. India comes in the Northern hemisphere with around 300 clear sunny days and solar insolation level ranges from 4 to 7 \(KWhr/m^2/day\).
Let us see the solar insolation levels of the top 5 solar states, in terms of solar PV installed capacity, of country:
Solar radiation in India
(1) Gujarat \((6.18 KWhr/m^2/day)\)
(2) Rajasthan \((6.09 KWhr/m^2/day)\)
(3) Madhya Pradesh \((5.94 KWhr/m^2/day)\)
(4) Maharashtra \((5.91 KWhr/m^2/day)\)
(5) Andhra Pradesh \((5.87 KWhr/m^2/day)\)
So, here we can see that the high solar insolation levels are one of the important growth accelerators of the Solar PV industry in these states.
