From what I can see, solar prices are going down just as much as oil. They will both be competing to keep prices down.
Solar has come down dramatically but marketers won’t market it for what it’s good for- low power demand.
They want to sell it for running whole houses: refrigerators, air conditioners- high power demand uses.
And it fails miserably at that.
Nearly everyone would have a short payback period putting their lights and other low power devices on a separate low voltage solar circuit. And those savings add up.
But the industry is pushing subsidized, long (risky) payback uses.
