Solar installation in San Diego.
ETW Energy installs solar and battery storage for homes across San Diego, served by SDG&E. California’s NEM 3.0 rules changed solar economics here significantly: exporting power to the grid now pays far less than it used to, which means a battery is usually essential — not optional — to get a real return.
With some of the highest electricity rates in the country, San Diego homeowners have a lot to gain from solar designed correctly for the current rules.
Why a battery is essential under NEM 3.0
With exports worth little, the value is in self-consumption: storing your midday solar and using it in the high-rate evening hours instead of buying expensive grid power. A battery is what captures that value, which is why we design most San Diego systems as solar-plus-storage.
High rates, strong sun
San Diego pairs an excellent solar resource with some of the nation’s highest electricity prices — which is exactly why a correctly designed system can offset so much cost. We size storage and solar together for your usage and rate plan.
Solar in San Diego — common questions
Do I need a battery with solar in San Diego?
Under NEM 3.0, usually yes. SDG&E now credits exports at a low value, so storing your solar in a battery and using it yourself is where the return comes from. A solar-only system captures much less.
Is solar still worth it in San Diego after NEM 3.0?
For many homes, yes — but the design has to fit the new rules. With high SDG&E rates and strong sun, a solar-plus-storage system can offset significant cost. We model it honestly for your home.
