It is difficult to find what is the installed rooftop capacity in the country. Two main reasons are:
– a lot of the service providers are not organized enough to update their work on central databases.
– As long as the system is not net-metered, the utilities do not know any better.
Bridge To India does a great job in collecting this information annually. In the Intersolar Mumbai 2015, their published that information. Today we will share some of the Rooftop Solar capacity updates, and more..
When we break this up by region though, the southern states have about 37% capacity to the western states at 25%. This is counter-intuitive considering that GJ and RJ were the farthest along on large scale projects. But the Rooftop Solar requires net metering and financing support. Kerala, TN, AP and KA all have great programs to promote Rooftop Solar, while the western states of GJ, RJ and MH are still getting their act together for it.
KPMG has been fairly regular with their predictions for the Indian Solar market. Their first solar report that we read was in 2011. They have also been consistently predicting about a 2017-18 timeframe for “grid parity”. I believe the industry beat their estimates –
– solar is at Grid Parity with diesel for last 3-4 years
– solar is at grid parity with commercial retail prices in most states in last 2 years
In terms of parity with whole-sale electricity price based on coal, 2 more years and we will be at APPC price in most large states.
Let’s always remember, solar is a TECHNOLOGY, not a FUEL. Technology prices ALWAYS go down with time.
MP is a great state in terms of it’s solar insolation and multiple Tier-2/Tier-3 cities and increased industrialization. It would be a perfect place to be covered with rooftop solar systems, but evidently it is not. The policies an support in MP has been lagging behind. But finally that seems to be changing with the programs like above. We are also hoping their net metering policy comes out soon in terms of implementation guidelines, etc.
