A few words from President Donald Trump about putting solar panels on the proposed wall at the U.S.-Mexico border sent solar stocks sharply higher on Thursday. SunPower (NASDAQ: SPWR) and Canadian Solar (NASDAQ: CSIQ) led the way, but First Solar (NASDAQ: FSLR) was also up as the whole sector seemed to be a bit cheerier being on Trump’s good side for once.
I first saw the idea of the “Solar Wall,” if you will, floated by SunEdison co-founder Jigar Shah on LinkedIn and it’s not at all a crazy idea if the wall is actually built. Unproductive space on the top or sides of the wall could generate hundreds of millions of dollars in electricity each year and pay for part of the wall’s cost. Trump says they’re working out the details and that makes it worth looking at how big the solar opportunity is on the wall and why Mexico and Canada could be the real winners if it’s built.
