This guide is written by a solar company. Why should I trust it?

Because we tell you that up front instead of hiding behind a fake review site. OC Solar wrote this guide, we put ourselves at #1, and we explain the criteria so you can pressure-test our reasoning. We name real competitors with neutral descriptions and links to their own sites, we never quote their ratings or prices (those drift and become false), and we encourage you to get multiple bids — including from companies on this list that are not us.

Why does a battery matter so much for San Diego solar?

SDG&E charges some of the highest electric rates in the United States, and under NEM 3.0 the utility pays very little for solar you export to the grid. A battery stores your midday production and discharges it during the expensive evening peak, which is where most of the savings live now. In San Diego, a company's battery design competence is not a nice-to-have — it is the difference between a system that pencils and one that disappoints.

Is the 30% federal solar tax credit still available in San Diego?

The federal residential tax credit (Section 25D) expired on December 31, 2025, so no honest installer should be promising you a 30% credit on a cash or loan purchase today. On lease, PPA, or prepaid plans, the financier that owns the system may still claim the surviving commercial credit (Section 48E) — available for systems placed in service through roughly 2027, with construction-start windows — and pass that value through as a lower price or payment. Treat it as a price benefit built into the plan, not a tax credit you claim yourself.

What should I do before signing a solar contract in San Diego?

Get at least two bids, verify each contractor's CSLB license, and read recent reviews on Google and Yelp — not just the testimonials on their website. Make sure the proposal models NEM 3.0 honestly, includes a battery sized to your actual evening usage, and does not bake an expired residential tax credit into the savings math. If you already have a quote in hand, we will review it line by line for free, even if you end up signing with someone else.

How do I find the best solar installer near me in San Diego?

Run a verification pass instead of trusting any ranking, including this one: check each company's current rating AND review volume on Google and Yelp (read the most recent reviews — a company's last 90 days tells you more than its lifetime average), confirm the CSLB license is active and bonded at cslb.ca.gov, and make every bidder show the battery math behind their savings projection. On SDG&E's rates, an installer who can't explain their NEM 3.0 storage strategy isn't a finalist.

What questions should I ask a San Diego solar company before signing?

Lead with three: What export rates does my savings projection assume under NEM 3.0, and what happens to those savings without a battery? What's your median sign-to-install timeline, in writing? And who services the system in year 7 — your own employees or a subcontractor? Then verify the basics yourself: an active, bonded CSLB license with workers' compensation at cslb.ca.gov, and live review profiles you've read recently. A good company answers everything without flinching.

Disclosed bias

This guide is published by OC Solar. We operate a San Diego office and we put ourselves at the top of the list.

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. Get more than one bid, check every contractor's license with the CSLB, and read their current Google and Yelp profiles yourself — including ours.

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.

Why San Diego is its own market

SDG&E's rates change what 'good' 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 — 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, through roughly 2027) and pass the value through as a lower payment — a price benefit, not a tax credit you file for.

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.
