Solar Repair & Troubleshooting — Half Moon Bay & the Coastside
Your system stopped producing. Your monitoring app is showing an error. Your bill went up and you're not sure why. Whatever the symptom, we can find the problem — and fix it.
Coastside Clean Energy is based in Pacifica. We troubleshoot and repair solar systems of all makes and brands across the Coastside: Half Moon Bay, El Granada, Montara, Moss Beach, and Pacifica. We're not the company that installed your system and we don't need to be — we work on everything.
(415) 236-0015 — Call or text to describe what you're seeing
We typically respond same day. If your system has stopped producing entirely, let us know and we'll prioritize the visit.
What are you seeing?
Here are the most common problems we diagnose on the Coastside — and what they usually mean.
Monitoring shows zero or reduced production
The most common call we get. Can indicate an inverter fault, a tripped breaker, a failed microinverter on one panel, or a communication issue. Usually diagnosable remotely before we visit.
Monitoring app is offline or not updating
Could be a communication module issue, a firmware problem, or a failed gateway — not always a production issue. We diagnose monitoring systems separately from production systems.
Inverter fault light or error code
String inverters and microinverters fail more often than panels — and they're the most common repair we perform. Enphase, SolarEdge, SMA, Fronius, Tesla, Lunar — we service them all.
Physical damage — storm, debris, or pests
Coastside homes deal with wind, debris, and significant wildlife pressure — particularly pigeons nesting under roof arrays. We assess panel damage, racking integrity, and wiring condition after weather events or pest intrusion.
Electric bill went up but nothing changed
Often means the system has been underperforming for months — sometimes silently. We pull production history and compare it against what the system should have generated based on local irradiance data.
System is old and I don't know if it's still working properly
If your system is 8 years or older and you've never had it inspected, a diagnostic visit is worth it. Connectors corrode, sealants fail, and microinverters degrade — often without visible signs.
Why Coastside solar systems need local expertise
The marine environment along Highway 1 is harder on solar systems than most homeowners realize. Salt air accelerates corrosion on connectors, conduit fittings, and racking hardware. Marine fog creates consistent moisture exposure that inland systems don't experience. And the temperature cycling between cold coastal mornings and warmer afternoons creates stress on sealants and roof penetrations over time.
Most Bay Area solar companies are based in the East Bay or the Peninsula and treat the Coastside as a long drive they'd rather not make for a service call. We're different — Pacifica is home, and Half Moon Bay, El Granada, Montara, and Moss Beach are our neighbors.
That proximity matters for repairs. A company that quotes you a three-week wait because they're routing a van from Fremont is going to cost you three weeks of lost production. We're usually on-site within a few days of a confirmed diagnosis.
We're brand-agnostic. If it's on a roof on the Coastside, we'll work on it.

How a service call works
1. Tell us what you're seeing
Call, text, or fill out the form below with a brief description of the issue. If you have a monitoring app, tell us the platform (Enphase Enlighten, SolarEdge mySolarEdge, Tesla app) and what error codes or readings you're seeing. We can often narrow down the cause before we arrive.
2. We schedule a diagnostic visit
We confirm a time that works for you and come to the property. The diagnostic visit covers a full assessment of the system — production, wiring, inverters, racking, roof penetrations, and monitoring. Most diagnostics take one to two hours.
3. You get a clear diagnosis and a fixed-price repair quote
After the visit, we explain what we found in plain language and give you a written quote for any repairs. No surprises, no pressure. If the repair is minor and we have parts on hand, we often complete it same-day.
4. Repair and verification
We complete the repair, verify production is back to expected levels, and confirm your monitoring is reporting correctly before we leave. You'll also get a written record of what was done for your files.
We're not the kind of company that shows up, installs, and disappears. We take the time to understand your home, your energy goals, and your budget — and we build a plan that actually makes sense for your situation. No pressure, no fluff, just honest advice and quality work.
Our team knows the San Francisco permitting process, PG&E's interconnection queue, and the unique challenges that come with older Bay Area homes. We've done this enough times in this city to know what to expect — and how to keep your project moving.
Why San Francisco homeowners choose Coastside Clean Energy
“It was really easy to work with Coastside. They were responsive, patient with changes I needed and did an exceptional job with the installation. If you want to go with a smaller local company , I would highly recommended Coastside.”

San Francisco, CA“Coastside Clean Energy did a great job explaining our options and doing a very solid install. They are very experienced with flat roofs (valuable in San Francisco) and install EV chargers and batteries as well. They also maintain systems and offer great service. I highly recommend them.”
— Lily S
San Francisco, CA“I enthusiastically recommend Coastside Clean Energy! Marcelo and crew did an excellent job installing 240 V electric connection for my new kiln. Clean, solid installation, with all required safety features. And such a pleasure to work with them. I am excited to have them upgrade my electric system for an EV charger and future solar as I move towards more electric appliances in my 80 year-old home.”

Berkeley, CASometimes a repair is the start of something bigger
A lot of our best customer relationships started with a repair call. Once we're on-site and the system is working again, it's a natural moment to talk about what's changed since the system was first installed — NEM 3.0 rate structures, battery storage economics, panel upgrade options, or EV charging if you've added a car.
We're happy to just fix the thing and leave. But if you want a bigger picture conversation, we're here for that too.
We also handle solar panel removal & reinstallation for roof replacements
If you're getting a new roof and need your panels temporarily removed, we coordinate directly with your roofer and handle the full removal, storage, and reinstallation. This is a common service on the Coastside, where aging wood-shake roofs often need replacement before homeowners expect.
Neighborhoods we serve in San Francisco
We work across the entire city including the Sunset, Richmond, Mission, Castro, Noe Valley, Bernal Heights, SoMa, Pacific Heights, Excelsior, and more. Not sure if we cover your neighborhood? Reach out — we'd love to take a look.
