if the price of solar panels has dropped like a stone, why hasn’t the consumer, either in industry or homeowners seen lower prices of an installed product? It happens in other “high tech” products like TV and computers - why not solar?
I'm no expert, but I can read a graph. Cost reductions in the previous 10 years haven't been that great, and if you include installation labor as a significant (and not decreasing) part of the total cost, I think you can see the answer to your question.
