SDG&E launches technology to cut costs of rooftop solar power

Solar power project elp 3

Last month, San Diego Gas & Electric began installations of a new technology that reduces the cost for many customers installing residential rooftop solar. Developed by SDG&E, the renewable meter adapters connect rooftop solar systems directly to the existing electric meter panel in as little as an hour.

The RMA technology allows rooftop solar customers to avoid the need for invasive and time consuming panel upgrades that typically cost over $2,500 not including the structural impacts to walls, stucco and landscaping, especially for older homes.

RMAs are among several SDG&E initiatives to support California's environmental goals and the growth of rooftop solar. In 2013, SDG&E developed an online application that reduces solar power interconnection times to an average of four to five calendar days, to our knowledge that is the fastest approval time in California. A growing number of customers are also taking advantage of SDG&E's "fast track" option that allows same-day connection.

RMAs will further speed up the solar interconnection process for SDG&E customers. The RMA costs about $1,300.

In addition to having met California's 33 percent renewable power goal, SDG&E provides the grid service that receives output from its rooftop solar customers during the day and delivers electricity to those customers when their solar panels are not producing electricity in the evening and at night. The SDG&E grid ensures safe and reliable power.

SDG&E is a regulated public utility that provides safe and reliable energy service to 3.4 million consumers through 1.4 million electric meters and 868,000 natural gas meters in San Diego and southern Orange counties
