Comparing quotes in Carlsbad?
Divide each quote's total, before incentives, by the system size in watts. Homeowners in Carlsbad who bought their system paid a median of $4.03/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 Carlsbad
602 of the 2,686 home solar systems installed in Carlsbad in 2023–2025 (22%) included a home battery, put in by 79 companies. These installed the most:
| Installer | With battery | Of its installs | Median price | Leased / PPA |
|---|---|---|---|---|
| 1. Sunrun | 155 | 43% | — | 95% |
| 2. Baker Electric Solar | 79 | 27% | $6.83/W | 3% |
| 3. Tesla | 73 | 57% | $4.60/W | 0% |
| 4. Stellar Solar | 64 | 36% | $4.52/W | 0% |
| 5. Semper Solaris | 31 | 27% | $6.01/W | 0% |
- Most common battery: Tesla (64% of those with a known brand), then Enphase Energy (11%).
- What a battery adds: owned systems with one had a median of $5.50/W, against $4.03/W for all home systems in Carlsbad. The recorded price includes the battery, so the gap (+1.47 $/W on a 6.9 kW system) is roughly what it cost.
- Battery on most of their jobs: Tesla (57%). The others add one on some jobs, not by default.
- Lowest median price among them: Stellar Solar, at $4.52/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 Carlsbad
When a system stops producing, the best first call is an established local company. The companies ranked above installed systems in Carlsbad 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.
59% of the home systems installed here in 2023–2025 use Enphase Energy inverters, followed by Tesla (17%). 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.
Checks to do before you call anyone: solar troubleshooting guide. Storm damage, a roof leak or a burning smell: what to do first.
Installers That Closed or Went Bankrupt in Carlsbad
At least 948 home solar systems in Carlsbad 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 Carlsbad: Common Questions
Who installs the most solar panels in Carlsbad?
In the most recent three years of records (2023–2025), Sunrun installed 361 home systems in Carlsbad, more than any other company. Baker Electric Solar (293) and Stellar Solar (177) came next. Volume shows local experience, not workmanship, so compare quotes and reviews before choosing.
How much does a solar system cost in Carlsbad?
Homeowners who bought their system outright paid a median of $4.03/W before incentives, and the typical system was 6.2 kW — about $25,000 in total. Prices vary by installer: in the ranking above, the median ranges from $3.04/W to $5.09/W.
Do most people in Carlsbad buy or lease their panels?
84% bought their system and 16% 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 Carlsbad?
Start with the companies in the ranking above: Sunrun, Baker Electric Solar and Stellar Solar 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 Carlsbad and what still works when an installer closes.
What do homeowners in Carlsbad 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.

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.
