Do you install solar in Granite Hills, CA?+
Yes. Granite Hills is part of our regular East County service map, and our crews work there out of our El Cajon office at 270 E Douglas Ave.
Is solar worth it for Granite Hills homes?+
Hot valley-edge climate with strong, consistent sun exposure. That usage pattern is exactly what solar offsets best, so most Granite Hills homes with SDG&E bills above roughly $150 a month see a strong return.
What kind of roofs do you work with in Granite Hills?+

Most Granite Hills projects run 6 to 10 weeks from signed agreement to SDG&E approval and activation. The on-roof work itself is usually one to two days.
Do you handle Granite Hills permits and SDG&E interconnection?+
Yes. We pull the local permits for Granite Hills, coordinate inspections, and file the SDG&E interconnection paperwork from start to finish.
