Interesting read over at Greentech Media about the role of solar heating and cooling in the US. While solar electric systems are more common, solar hot water systems are viable and cost-effective as well, and we could see more widespread adoption in the near future with the right targets and incentives in place. From the article:
“The payback depends on the location, the type of technology, and the local incentives, but it is generally three to seven years,” Pilgaard said. “The national average cost of electricity is $0.12 per kilowatt-hour to $0.14 per kilowatt-hour. PV with incentives is at grid parity at around $0.13 per kilowatt-hour to $0.14 per kilowatt-hour. Solar thermal with incentives is around $0.06 per kilowatt-hour and cost-effective in places that use oil for heating. But it displaces natural gas in 50 percent of the U.S. water heating market, and natural gas is $0.04 per kilowatt-hour.”
