The financial units of PG&E Corp and SunRun Inc. have come together and have decided that they will come up with a corpus of $100 million. This money will then be used for a program that will help more than 3,500 residential solar installations during 2010.

The program will be carried forward to the next year as well and will be spread across five states of the US.

Most of the money for the fund will be provided by the shareholders of PG&E. The money will be directed through their Pacific Energy Capital II subsidiary.

The program will deal primarily with the rooftop-energy systems and will help the homeowners set up solar panels without incurring any high cost. But they will have to become part of power-purchases agreements and solar leases.

SunRun will be contributing with the help of its services and will also be providing the technical support to the whole thing. SunRun currently has 4,000 customers and provides its service in five states.

PG&E said that it is very optimistic about the program which is part of their alternative-energy projects. It has already received approval from the state regulators of California.
