Solar installation in San Jose.
ETW Energy installs solar and battery storage for homes across San Jose, where PG&E delivers power and California’s NEM 3.0 rules apply. As in the rest of Silicon Valley, exporting solar to the grid now pays far less than it used to — which means a battery is usually essential to get a real return, not an optional upgrade.
With some of the highest electricity rates in the country, San Jose 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 expensive evening hours instead of buying grid power. A battery captures that value, which is why we design most San Jose systems as solar-plus-storage.
High rates, strong sun
San Jose pairs an excellent solar resource with some of the nation’s highest electricity prices — 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 Jose — common questions
Do I need a battery with solar in San Jose?
Under NEM 3.0, usually yes. PG&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.
Does San Jose Clean Energy change how solar works?
San Jose Clean Energy provides your generation, but PG&E still delivers the power and the NEM 3.0 export rules still apply. We design around the current rules and confirm the specifics for your address.
