I hadn't seen this posted to the Houston Renewable group so in case there is interest. TXU up in Dallas has partnered with SolarCity to offer a lease or buy program for residential solar installs. This is in tandem with what I assume is a feed in tariff from Oncor to buy the electricity.
Oncor offers a rebate of $2.46 a watt up to $24,600 for a
residential solar installation. Funds are currently available to include about
400 homes in the program, according to TXU Energy.
