A series of tax credits for wind, solar, geothermal, tidal energy and others was among the tenets of the October congressional financial rescue legislation.
The law increased the investment credit for solar from $2,000 to $7,500 for a buyer who spends $25,000 to install solar panels on his roof.
In states like California, Connecticut, and New Jersey, where the cost of power is considerable, the pretax compound rate of return on a typical home solar system will be greater than 15 percent per year, says Andy Black, CEO of OnGrid Solar, an industry research firm.
Home builders, including some of the biggest, such as Centex, Lennar, Pulte Homes, and Woodside Homes, are seeing advantages to including solar. All are developing successful communities where all of the homes have solar panels capable of making most if not all power.
