Despite foot-dragging by the state’s leadership on solar policies, residential solar installation prices recently hit $3.90 per watt in Texas, lower than anywhere else in the nation. It’s part of a nationwide plunge in installation prices for the smaller systems — generally 10 kilowatts or less — used for individual homes. According to a new report out of the U.S. Department of Energy’s Lawrence Berkeley Laboratory, that national price fell from around $12 per watt in 1998 to $5.30 per watt in 2012.
Large utility-scale solar systems saw a similar plunge in installation price, hitting $4.60 per watt in 2012. But it’s the small, distributed residential systems that could fundamentally remake the electricity market in America, and have been a large part of the growing pro-solar coalitions between environmentalists and the Tea Party. Granted, residential solar is still a relatively small slice of national capacity, but it’s also been the least sensitive to seasonality and market volatility.
