Common questions about solar electrician and battery backup installation in El Cajon

Battery or generator for backup?

Batteries are quiet, automatic and recharge from solar. Generators run longer on fuel. Some El Cajon properties use both. See generator installation for the other side of the comparison.

Do you install the solar panels themselves?

Our focus is the electrical work: interconnection, batteries, panels and backup circuits. We coordinate with your solar installer, and we can pair the project with EV charger installation.

Will my solar work during an outage?

Standard grid-tied solar shuts down when the grid does. To keep power on you need a battery or other backup-capable equipment that disconnects from the grid automatically. We can add that to many existing systems.

How many batteries do I need?

One battery typically carries lights, refrigeration, internet and outlets overnight. Running air conditioning or a well pump takes more. We size storage around the circuits you actually want backed up.

In customers' words

After two long outages we had a standby generator put in. They sized it properly instead of pushing the biggest unit, and showed us how the transfer switch works.

Rob H.Standby generator

They installed our Level 2 charger in the garage and explained the load calculation in plain English. Clean conduit run, no mess, and the price matched the quote.

Priya S.EV charger installation

After a surge took out our garage door opener and a TV, they installed a whole house protector at the panel. Quick job, clear price, no upsell.
