Solar Panel Removal and Reinstallation in New Hampshire: Costs, Warranties & How to Avoid Getting Stuck
If your New Hampshire home has solar panels and your roof is nearing the end of its life, you’ve discovered one of the most frustrating corners of homeownership: your roofer won’t touch your panels, and your solar company won’t do your roof. That gap between trades is exactly where solar panel removal and reinstallation — often called a “detach and reset” — comes in. This guide covers what it costs in NH, how to protect your warranties, and the one decision that saves most homeowners thousands of dollars and weeks of downtime.
Why NH Homeowners Need This Service Right Now

New Hampshire’s first big residential solar wave happened more than a decade ago — and those panels were installed on roofs that were already mid-life. Asphalt shingles last 20–25 years; solar panels are engineered for 30+. That lifespan mismatch means thousands of
NH roofs need replacement
underneath working solar arrays, from Manchester and Nashua to Londonderry, Derry, and the Seacoast.
The frustrating part is how often homeowners get trapped in the middle:
- Your roofer refuses to remove the panels. Roofers aren’t licensed electricians, and disconnecting a live grid-tied system exposes them to arc flash, ground faults, and liability they won’t accept
- Your original installer is gone. Many of the national solar companies that flooded NH in the 2010s have since left the market or been bought out — leaving “orphaned” systems with no one to call. Some surviving installers quote $5,000+ for a removal/reinstall they didn’t even install
- One wrong move voids your warranty. Panels generate electricity whenever light hits them — even on cloudy days — and manufacturer warranties (typically 25 years) generally require removal and reinstallation by certified professionals

What Does Solar Panel Removal and Reinstallation Cost in NH?
National benchmarks put professional removal and reinstallation at roughly $200–$300 per panel, so a typical 20-panel array runs $4,000–$6,000 and a 30-panel system $6,000–$9,000 — before any roofing work begins.
Some providers structure it as $100–$175 to remove each panel plus $125–$200 to reinstall it, with flat fees of $3,000–$5,500 for a typical 20-panel system.
What moves the number up or down:
One NH-specific money-saver: if your removal is triggered by storm damage — hail, wind, a fallen tree from one of our Nor’easters — the removal and reinstallation cost may be includable in your homeowner’s insurance claim. File the claim before any work begins and get a separate R&R quote to hand your adjuster.
The Sunergy Detach-and-Reset Process
-
System documentation — Before a single panel comes off, we photograph and map the entire array, test every panel and optimizer, and record serial numbers. This protects you if anything is damaged and dramatically speeds up the reset.
-
Electrical shutdown & permits — Licensed electrical disconnection (a live rooftop string can carry hundreds of volts even with the inverter off), plus the permits your NH town requires.
-
Panel removal (Day 1) — Panels, racking, and wiring come off carefully; panels are stored securely on-site where possible to avoid storage fees.
-
Roof work — This is where Sunergy is different: our own roofing crew replaces or repairs the roof — no coordination games between two contractors, no gap where “nobody owns the leak.”
-
Reinstallation & recommissioning (Days 2–3) — Panels go back on as soon as the roof passes inspection, the system is recommissioned, monitoring is verified, and you’re producing again — typically down for days, not weeks.
Because the roof and the array live under one 20-year workmanship warranty, there’s no finger-pointing if an issue ever appears at a roof penetration — a scenario that splits warranties and budgets when you hire two separate contractors.
Frequently Asked Questions: Solar Panel Removal & Reinstall in NH
How long does the whole process take? Removal is typically one day, roofing one to three days, reinstallation one to three days. With one contractor coordinating everything, most systems are down for days rather than weeks.
Will removing my panels void the warranty? Not if done properly by certified installers — your 25-year panel warranty and 12–25-year inverter warranties survive a professional detach and reset. What voids coverage is an unlicensed person (like a roofer) disconnecting or handling the equipment.
Can I just have my roofer take the panels off? Strongly advised against. Live electrical hazard aside, manufacturer warranties and many original installation contracts require authorized professionals to touch the system — a roofer-led removal can void both your equipment warranty and your original installer’s workmanship warranty.
What if my original solar company went out of business? You’re not stuck. Your equipment manufacturer warranties remain valid, and any qualified, licensed solar installer can perform removal and reinstallation on any major brand — SolarEdge, Enphase, Tesla, REC, Q Cells, and others.
Should I replace my roof and panels at the same time? If your panels are 15+ years old, a roof project is the cheapest moment to evaluate an upgrade — while everything’s already off the roof. We’ll give you an honest assessment of whether your existing array has years of life left.
Do I need permits for this in New Hampshire? Usually yes — solar disconnection and reconnection is electrical work requiring an electrical permit, and the roof work requires its own building permit. Sunergy handles all filings and inspections as part of the project.
