Beware possible increase in solar panel prices. Uncertainty Grips Solar as Industry Awaits Trump's Tariff Ruling My wife and I are thinking of moving our solar install up to this fall instead of next spring as originally planned to make sure we don't get bitten by this. If it were up to me, if a fair case could be made that foreign countries were subsidizing their solar to get a leg up on American manufacturers, I would simply subsidize American manufacturers by a similar amount. Promote solar! But our administration is more interested in bringing back coal. Solar is only good for walls.
