Rooftop solar PV will reach grid parity in 50 US states by 2016 – up from just 10 now – setting the scene for a dramatic increase in the uptake in household and commercial rooftop solar in the world’s biggest economy.

That’s the prediction of Vishal Shah, the leading solar industry analyst at Deutsche Bank, who says that declining system costs, customer acquisition costs, financing costs and rising volumes should drive significant scale benefits .

Shah’s prediction was included in his first report on the newly listed Vivint Solar, which is the number two installer in the US. Deutsche Bank considers its prospects are so good that it will at least double its sale in each of the next two years.

But it is also predicting big things for the US market, based on a continued fall in installation costs of solar, the cheaper cost of finance as new financial models attract more mainstream funding, and assuming that the attempts by utilities to curtail the proliferation of solar are resisted.
