Comparing quotes in Hamilton?
Divide each quote's total, before incentives, by the system size in watts. Ask at least three of the companies above to quote the same system size. Reject any 2026 quote that subtracts a 30% federal tax credit from a purchase: that credit ended in 2025.

Solar Panel Repair in Hamilton
When a system stops producing, the best first call is an established local company. The companies ranked above installed systems in Hamilton 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.

Installers That Closed or Went Bankrupt in Hamilton
At least 118 home solar systems in Hamilton 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 Hamilton: Common Questions
Who installs the most solar panels in Hamilton?
In the most recent three years of records (2023–2025), Sunrun installed 173 home systems in Hamilton, more than any other company. SunnyMac (85) and Trinity Solar (68) came next. Volume shows local experience, not workmanship, so compare quotes and reviews before choosing.
Do most people in Hamilton buy or lease their panels?
24% bought their system and 76% 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 Hamilton?
Start with the companies in the ranking above: Sunrun, SunnyMac and Trinity 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 Hamilton and what still works when an installer closes.
What do homeowners in Hamilton pay for electricity?
Residential customers in New Jersey pay an average of 24.95¢ per kWh, 43% above the national average. The higher the rate, the faster solar pays for itself. Source: EIA, Electric Power Monthly, Table 5.6.A.
No company pays to be listed or to rank higher, and any ad on this site is labeled. Before you sign, confirm the contractor license, insurance and recent reviews, and get at least three quotes. If a company in Hamilton has closed, moved or changed its phone number, tell us and we'll check it.
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.
