Every company in the ranking was still installing in 2025; installers that have since closed are left out.

Comparing quotes in Concord?
Divide each quote's total, before incentives, by the system size in watts. Homeowners in Concord who bought their system paid a median of $4.50/W in 2023–2025. Reject any 2026 quote that subtracts a 30% federal tax credit from a purchase: that credit ended in 2025.
How to check a solar quote →Solar Battery Installers in Concord
1,089 of the 1,963 home solar systems installed in Concord in 2023–2025 (56%) included a home battery, put in by 111 companies. These installed the most:
| Installer | With battery | Of its installs | Median price | Leased / PPA |
|---|---|---|---|---|
| 1. Sunrun | 268 | 67% | — | 96% |
| 2. V3 Electric | 106 | 96% | — | 73% |
| 3. Tesla | 104 | 85% | $4.56/W | 0% |
| 4. Bright Planet Solar | 87 | 81% | $6.62/W | 71% |
| 5. Got Watts Electric | 48 | 74% | $5.66/W | 0% |
- Most common battery: Tesla (53% of those with a known brand), then Enphase Energy (21%).
- What a battery adds: owned systems with one had a median of $5.16/W, against $4.50/W for all home systems in Concord. The recorded price includes the battery, so the gap (+0.66 $/W on a 6.6 kW system) is roughly what it cost.
- Battery on most of their jobs: Sunrun (67%), V3 Electric (96%), Tesla (85%), Bright Planet Solar (81%), Got Watts Electric (74%), Richard Heath Associates (100%), Empower Electric (52%), Semper Solaris (50%), Ambrose Solar (52%), North Valley (100%). The others add one on some jobs, not by default.
- Lowest median price among them: Tesla, at $4.56/W for systems the homeowner bought.
Ask whether a battery quote backs up the whole house or only a subpanel, and size it from your bills: one 13 kWh battery covers essentials overnight, not central air. Under California's Net Billing Tariff (from April 2023) exported solar earns little, so storing it for evening use is what makes a battery pay. More in Tesla Powerwall installation.

Solar Panel Repair in Concord
When a system stops producing, the best first call is an established local company. The companies ranked above installed systems in Concord through 2025, so they know the equipment on local roofs. Many will service a system they didn't install, but not all — ask before you book, and expect a diagnostic fee.
39% of the home systems installed here in 2023–2025 use Enphase Energy inverters, followed by SolarEdge (28%). Enphase systems use a microinverter under each panel, so one failure usually knocks out a single panel and the monitoring app shows which one. Systems with a central (string) inverter — SolarEdge and others — stop producing entirely when that inverter fails; a dark screen or an error code on the unit on your wall is the usual sign.

Installers That Closed or Went Bankrupt in Concord
At least 904 home solar systems in Concord were installed by companies that have since closed, liquidated or filed for bankruptcy. They are left out of the ranking above. If one of them installed your system, its workmanship warranty is likely gone — but panel and inverter warranties come from the manufacturer and usually survive the installer.

Solar in Concord: Common Questions
Who installs the most solar panels in Concord?
In the most recent three years of records (2023–2025), Sunrun installed 401 home systems in Concord, more than any other company. Tesla (122) and V3 Electric (110) came next. Volume shows local experience, not workmanship, so compare quotes and reviews before choosing.
How much does a solar system cost in Concord?
Homeowners who bought their system outright paid a median of $4.50/W before incentives, and the typical system was 6.4 kW — about $29,000 in total. Prices vary by installer: in the ranking above, the median ranges from $3.99/W to $6.49/W.
Do most people in Concord buy or lease their panels?
67% bought their system and 34% leased it or signed a power purchase agreement (PPA). With a lease or PPA you pay little upfront, but you don't own the panels and the savings are smaller over the contract. Some installers sell almost only one way — check the "Leased / PPA" figure for each company in the ranking.
Who repairs solar panels in Concord?
Start with the companies in the ranking above: Sunrun, Tesla and V3 Electric did the most work here, and an installer that knows the equipment on local roofs can usually diagnose a fault faster. If your system was leased or is on a PPA, call the company you pay each month first — maintenance is normally its job.
Can I still get the federal solar tax credit in 2026?
Not as a homeowner buying the system: the 30% residential credit (Section 25D) ended on December 31, 2025. Be wary of any quote that still subtracts it from the price. See our 2026 solar tax credit guide for what's left.
What if my solar installer went out of business?
Your panels and inverters are still covered by their manufacturers' warranties; what you lose is the installer's workmanship and roof-leak warranty. If the system is leased or on a PPA, the company you pay each month is usually responsible for repairs, and any active company in the ranking can take over service. See the installers that closed in Concord and what still works when an installer closes.
What do homeowners in Concord pay for electricity?
Residential customers in California pay an average of 34.74¢ per kWh, 99% above the national average. The higher the rate, the faster solar pays for itself. Source: EIA, Electric Power Monthly, Table 5.6.A.
No company pays to be listed or to rank higher, and any ad on this site is labeled. Before you sign, confirm the contractor license, insurance and recent reviews, and get at least three quotes. If a company in Concord has closed, moved or changed its phone number, tell us and we'll check it.
How This Ranking Works
Companies are ranked by the home solar systems they installed here in 2023–2025, from utility and state records; each needs at least 10 local installations and must still have been installing in 2025. Closed or bankrupt companies are removed and listed separately. The count shows local experience, not workmanship or service.
