Solar Panel Orders Point to Clean Energy Boom From US Climate Law

The full effects of the Inflation Reduction Act have yet to be felt, but a look at one major solar company’s order book suggests huge demand.

Over the past five decades, the US has installed about 140 gigawatts of solar power generation capacity, enough to provide more than 3% of its power. That is just a start: Between now and the end of the decade, the country might add three times that much .

It might seem fanciful to expect a market to quadruple in size in only eight years. But for that we can thank President Joe Biden’s Inflation Reduction Act and its generous, decade-long subsidies for both clean energy manufacturing and generation in the US. Adding 360 gigawatts of solar in eight years does not require an exceptional year-on-year growth rate, though it does require investment. And it will certainly need a speeding up of the often-fraught process of interconnection that brings new projects onto the grid.
