Solar power in Rancho Cucamonga, California

Both RCMU and Southern California Edison both have a solid net metering plan for its solar customers. Net metering requires your utility to credit you 1 for 1 with each kWh exported to the grid and credit you for the excess after wiping out your nighttime or cloudy day power bill. RCMU's net metering plan is slightly better as it doesn't require customers to switch to time of use billing which reduces returns by about 10%.

The generous solar system rebate program offered by RCMU in 2017 has now ended after successfully meeting the City's targets, and more than 1 Megawatt of solar will be installed to the end of 2018.

However, despite the end of the rebate program, solar remains a very attractive proposition for nearly all home owners in the City of Rancho Cucamonga due to the exceptional levels of sunshine and the relatively high cost of utility power. Projections of system payback time using the Solar Estimate Calculator continue to indicate a full cost recovery time of 5-7 years, which is then followed by 20 or more years of virtually free power.

Even if you are not convinced about solar we recommend that at the very least you use the solar panel calculator for Rancho Cucamonga to find out:
