California is the first state in the nation to install more than 1,000 megawatts of customer generated solar power, with more than 300 megawatts put on rooftops last year alone.
The California Public Utilities Commission Report says there are more than 122,000 customers that have installed solar arrays in the past five years.
The report is an assessment of the the California Solar Initiative's push to expand solar power. The goal is to triple the 1,000 megawatts currently in service.
The number of solar installations is climbing at the same time as the state's incentives are going down, according to the report.
"Part of the reason we're seeing that is we're seeing different models enter the market," said Melicia Charles of the California Public Utilities Commission. "So, not only can homeowners own systems, but there are solar leases available and other third part-owned systems out there, and businesses out there."
Charles says the cost of systems dropped nearly 28 percent since 2007.
