Common service requests

Six things we fix every week.

If your system is doing any of these, call us first. About 60% of production-loss issues are solved without a site visit.

Production drop

June production this year is 20% below last June. Common culprits: dead optimizer, failing inverter, dirty panels, or a tripped breaker.

Inverter fault

Red light on the inverter, error code, or "no production" alert. Most are field-recoverable; some require a manufacturer warranty claim, which we file for you.

Monitoring outage

Solar producing fine but the app shows "offline." Usually a router, gateway, or cell-modem issue. We fix it remotely whenever possible.

Panel cleaning

Pollen, soot near highways, salt near the coast — sometimes panels need a real cleaning. Annual cleaning typically recovers 3 – 8% of production.

Animal damage

Squirrels chewing wires, birds nesting under panels — common in older arrays without critter guards. We repair the damage and install guards on the same trip.

Storm or snow damage

Cracked glass, dislodged panels, or roof leaks after a heavy snow load or storm. Insurance documentation included with every diagnostic visit.

Diagnostic process

Remote first. Truck second.

We do not bill you for a truck roll until we know we need one. Most monitoring and inverter issues are diagnosed in the first 30 minutes from our office.

Remote check first

Most production drops can be diagnosed remotely from your monitoring data. We pull the logs and identify the issue before scheduling a truck — saves you a service-call fee.

On-site diagnostic

If remote diagnosis is inconclusive, our NABCEP-certified technician comes to your home. Same crew, no subcontracted "service partner."

Fix or warranty claim

Field-recoverable issues we fix on the visit. Equipment failures we file the manufacturer warranty claim and coordinate the replacement. You do not chase the manufacturer.

What customers say

Trusted by homeowners
who value quality.

“Teamsun was the only crew that walked the roof, named the panel brand, and answered every question without checking with someone. Same lead tech came back a year later when I added a battery.”
Robert P. Homeowner · Glastonbury, CT
“Three of my neighbors had Teamsun, so I called them. The crew was on my street five days after I signed.”
David L. Homeowner · West Hartford, CT
“They knew the historic district secretary by first name. Saved us six weeks on permitting alone.”
The Hwang family Homeowners · Glastonbury, CT
“Same lead tech who installed it came back four years later to swap an inverter under warranty. No charge, no excuses.”
Sandra M. Homeowner · Worcester, MA
Service FAQ

Questions homeowners ask when something is wrong.

Will you service a system Teamsun did not install?

Yes. Most of our service work is on systems other installers built. We handle every brand and inverter on the market. We do not extend our 10-year workmanship warranty to outside installs, but we do file manufacturer warranty claims on your behalf.

How much does a service call cost?

Remote diagnostics are typically free. On-site diagnostic visits run $150 – $300 depending on travel distance. Repair labor is quoted after diagnosis — no blind estimates. Manufacturer warranty replacements are usually free except for labor.

My system is producing 30% less than last year. What should I do?

Email us your monitoring login or screenshots from the last 12 months. We pull the data, diagnose remotely, and tell you whether you need a truck or just a setting change. About 60% of production drops are diagnosed without a site visit.

My inverter died and the original installer is out of business. Can you help?

Yes — this is a common call for us. We file the manufacturer warranty claim on your inverter (typically 10 – 12 year coverage). If the warranty has expired, we quote a replacement with a fresh modern inverter under new warranty.

How fast can you respond to a service request?

Production-loss diagnostics: same-day remote check. On-site visits: 5 – 10 business days for non-emergency. Storm damage and total system outage: usually within 48 hours, prioritized over routine work.

Do you do panel cleaning?

Yes — usually as part of a broader inspection visit. Annual cleaning is rarely worth a dedicated trip unless you are near agriculture, heavy industry, or the coast. We will tell you honestly during the visit whether your panels actually need cleaning.

Will Teamsun honor the original installer's workmanship warranty?

No — we only honor our own workmanship. We do file manufacturer warranties (panels, inverter, battery) on your behalf regardless of who originally installed. If you need workmanship coverage on an outside install, talk to your original installer.

Can you upgrade my system while you are here for a repair?

Often, yes. If your inverter is failing and warranty replacement is uneconomical, we frequently quote an upgrade in the same visit — see our system upgrades service. Aurora model included.
