Hiring a solar company in Santee

Solar companies in Santee need an active City business license to file a SolarAPP+ permit on SanteePortal.org, and a completed Permit Declaration Form before the City will schedule the inspection; batteries in a garage must follow the City's own placement guidelines. SDG&E supplies both delivery and generation, with no community choice provider. Compare at least three written bids built on your own SDG&E bill.

Start with your Santee electricity bill

Santee is SDG&E territory with no community choice provider on the Energy Commission's maps, and San Diego Community Power's member list does not include it. SDG&E supplies generation and delivery, and its Solar Billing Plan puts residential solar customers on EV-TOU-5, where on-peak runs from 4 to 9 p.m. and export credits are valued by the hour. Each bidder should model that plan from your usage.

Santee's SolarAPP+ steps

The City has streamlined small rooftop solar permits and takes applications on SanteePortal.org, where it says most are reviewed within 10 days. For eligible roof-mounted retrofit systems, SolarAPP+ replaces plan review. The contractor submits the design on SolarAPP+, pays its processing fee and downloads the approved plans and certificate. It then applies for a City of Santee SolarAPP+ permit on the portal, which requires an active Santee business license, attaches the Permit Declaration Form and pays for the permit.

The inspection is requested through the same portal account, and the City will not schedule it without the completed Permit Declaration Form. Where a battery is part of the job, the fourth step is to verify its location against the City's Residential Batteries in Garage Guidelines. Systems that do not qualify for expedited processing, including some pool and water heating systems, may need a detailed review.

Santee's permit numbers and SDG&E bill

Santee's reports to the Energy Commission show the instant route catching on: 780 residential solar permits in 2023, about 2% issued online, and 336 in 2024, about 26% online. Storage rose from about 13% of permits to 34% over the same two years.

Santee is not one of San Diego Community Power's member cities, so an SDG&E bill here has SDG&E generation charges rather than SDCP's. On SDG&E's Solar Billing Plan, residential customers use EV-TOU-5, exports earn credits by the hour, excess credits roll forward, and a system can be sized up to 50% above past use only with an attestation that usage will grow. A bid that quotes SDCP's bonus for a Santee home is modeling the wrong provider.

What a Santee quote needs to explain

A comparison to ask for

If a Santee bid includes a battery in the garage, ask how its placement meets the City's Residential Batteries in Garage Guidelines, since the City lists that check as a step of the SolarAPP+ process. Then compare each proposal's SDG&E bill under EV-TOU-5 with and without the battery.
