As the US solar industry grows, prices have fallen virtually across the board for the various customer sectors and regions. This is great news for solar shoppers and for the country as a whole. Like many high technology industries, as a product gets more mature companies get better at building and delivering the product to consumers. We have seen the fall in prices in computers, televisions, mobile devices, telecoms, automobiles, even air travel. Either the product has become outright less expensive to purchase, or the functionality and performance have been dramatically increased while maintaining a rough cost parity or decrease.
