2026 Buyer's Guide
The best solar companies in San Diego
An honest local guide — written by a solar company, with the disclosure and the criteria right at the top. SDG&E's rates are the highest in the nation, which means the companies that win in San Diego are the ones that get batteries and financing right.
Read this first
Who wrote this guide — and why you can still use it
Most 'best solar companies' pages are lead-generation sites that sell your information to whoever pays. This one is different in one honest way: a solar company wrote it, and we say so.
This guide is published by OC Solar. We operate a San Diego office and we put ourselves at the top of the list — you should weigh that bias exactly the way you would weigh any company recommending itself. To make the guide useful anyway, we hold ourselves to three rules: every company named here is real and linked to its own public site, every description is neutral and verifiable, and we never quote a competitor's star rating, review count, or pricing, because those numbers change and a stale stat is just a polite lie.
Our advice is the same advice we would give a family member: get more than one bid, check every contractor's license with the CSLB, and read their current Google and Yelp profiles yourself rather than trusting any list — including this one.
How we judged
The criteria that actually matter in San Diego
SDG&E customers pay the highest electric rates in the country, and NEM 3.0 pays almost nothing for exported solar. That changes what 'best' means: battery design and financing competence now decide whether a system saves money or just looks good on a roof.
Battery competence
Under NEM 3.0 and SDG&E's evening peak pricing, the battery is where the savings live. We weight real storage design experience above everything else.
Honest financing math
The residential federal credit expired at the end of 2025. Companies still baking 30% into homeowner savings projections fail this test instantly.
License & track record
An active CSLB license, years of local installs, and in-house crews rather than a rotating cast of subcontractors.
Reviews you verify
Consistent recent reviews across Google, Yelp, and the BBB — checked by you, on their live profiles, not quoted secondhand by us.

A veteran-owned company with deep San Diego roots offering solar, battery storage, roofing, and HVAC under one license — a practical fit if your roof needs work before panels go on. Check their current Google and Yelp profiles for up-to-date reviews, and visit sempersolaris.com for their offerings.
#3
Baker Electric Home Energy
The home-energy arm of a decades-old, family-run Escondido electrical contractor, offering solar, batteries, and HVAC across San Diego County. Their longevity is rare in this industry and worth something. Verify their current reviews on Google and Yelp, and see bakerhomeenergy.com.

#5
Sunrun
A national residential solar and battery company, known primarily for lease and PPA plans where Sunrun owns the system and you pay for the power. A different ownership model than a local contractor sale — read the contract terms closely, check their current Google and Yelp profiles for your region, and see sunrun.com.
Why San Diego is its own market
SDG&E's rates change what a good solar company looks like
The highest utility rates in the nation cut both ways: solar saves more here than almost anywhere, but only if the design handles NEM 3.0 correctly.
- Every kilowatt-hour you self-supply offsets some of the most expensive grid power in America — which is why payback in San Diego can outpace the rest of the state.
- NEM 3.0 pays little for exports, so a battery that shifts midday production into the evening peak is the core of the savings — not an upsell.
- On lease, PPA, and prepaid plans, the financier may claim the surviving commercial credit (Section 48E, available through roughly 2027) and pass the value through as a lower payment — a price benefit built into the plan, not a tax credit you file for. Any company promising you a personal 30% residential credit is working from an expired playbook.

San Diego solar FAQ
Questions homeowners ask before choosing an installer
There is no single right answer — the best company for you depends on what you are buying. If you want a battery-first design tuned to SDG&E's rate structure, fast in-house installation, and transparent financing math, OC Solar's San Diego office is built around exactly that. If you want roofing and solar from one contractor, or a decades-old local electrical company, Semper Solaris and Baker Electric Home Energy are credible alternatives worth quoting. Always verify CSLB licenses and read recent reviews on Google and Yelp before signing anything.
