Solar Warranty Coverage in Connecticut
Coverage you can count on.
Every SunPol installation comes with layered warranty protection — from the panels on your roof to the workmanship of our local crew. Coverage details depend on your financing path.

What each warranty layer protects.
Panel manufacturer warranty
Covers product defects and guarantees panels produce at least 80–85% of rated output at year 25. If they fall below that threshold, the manufacturer repairs or replaces them — no cost to you.
- Cell degradation beyond spec
- Manufacturing defects
- Output performance guarantee
Microinverter warranty
Covers hardware failures and electrical defects in the inverters that convert your panels' DC power to usable AC power. micro inverters carry one of the longest warranties in the industry.
- Hardware component failures
- Electrical defects
- Manufacturer replacement
SunPol workmanship warranty
Our guarantee that the installation was done right. If anything we installed fails due to how it was installed, we come back and fix it — free. After 10 years, manufacturer warranties still apply but service calls carry a labor cost.
- Wiring and connections
- Mounting and racking
- All electrical work
Roof penetration warranty
Guarantees every hole drilled for panel mounting will not cause roof leaks. If water comes through where we mounted the system, we fix the leak and any resulting damage at no cost.
- Mounting bolt seals
- Flashing and waterproofing
- Leak-related damage repair
- Panel manufacturer warranty (25+ years)
- Covers product defects and guarantees panels produce at least 80–85% of rated output at year 25. If output drops below spec, the manufacturer repairs or replaces at no cost.
- Microinverter warranty (25 years)
- Covers hardware failures and electrical defects in inverters that convert DC to AC power. micro inverters carry one of the longest warranties in the industry.
- SunPol workmanship warranty (10 years)
- Guarantees the installation was done correctly. If anything SunPol installed fails due to installation quality, SunPol returns and fixes it free of charge.
- Roof penetration warranty (10 years)
- Guarantees every hole drilled for panel mounting will not cause roof leaks. Covers mounting bolt seals, flashing, waterproofing, and leak-related damage repair.
What falls outside warranty coverage.
Warranties cover equipment and installation — not everything that can happen to a roof or home. Understanding the boundaries helps you plan.
- Pre-existing roof damage. If your roof was already compromised before installation, leaks from those areas are not covered. We inspect before we install and flag issues.
- Acts of nature beyond equipment ratings. Panels are rated for hail up to 1 inch and wind up to 140+ mph. Damage from extreme events beyond those specs may require a homeowner's insurance claim.
- Modifications by third parties. If another contractor alters the system, SunPol's workmanship warranty no longer applies to the modified components. Manufacturer warranties remain intact.
- Normal cosmetic wear. Minor surface scratches, color fading on mounting hardware, or dirt buildup are not defects and don't affect performance.

How to file a warranty claim.
If something's not working right, here's how to get it resolved:
1. Call or email us
Reach us at (860) 747-6527 or contact@sunpolsolar.com. Describe the issue — no formal paperwork needed to get started.

Warranty questions.
What is covered under the prepaid solar lease warranty?
Full service and maintenance for the entire 25-year lease term. Panels, inverters, wiring, and mounting are all covered at no additional cost. At lease end, you can buy at fair market value, renew for 5 years, or request free removal.
Who handles the warranty on a solar PPA?
The PPA provider owns the system and is responsible for all warranty claims, maintenance, and repairs for the duration of your agreement.
What happens if my solar panels underperform?
Tier 1 panel manufacturers guarantee at least 80–85% of rated output at year 25. If panels fall below that threshold, the manufacturer repairs or replaces them under warranty.
What is the difference between a manufacturer warranty and workmanship warranty?
The manufacturer warranty covers the product itself — panel cells, inverter hardware. The workmanship warranty covers how SunPol installed it — wiring, connections, mounting, racking, and electrical work.
What warranty does SunPol offer on cash purchase installations?
Cash purchases include the manufacturer's 25-year panel warranty, 25-year micro inverter warranty, and SunPol's 10-year workmanship and roof penetration warranty.
Does SunPol's warranty cover roof leaks?
Yes. Our 10-year roof penetration warranty covers any leaks caused by the solar installation. If water comes through where we mounted the panels, we fix it at no cost.
