Cape May is a National Historic Landmark city, which changes the order of operations for solar here. Before a building permit is issued, your application is referred to the Historic Preservation Commission, and the commission judges panels against written standards for visibility and compatibility with the district. The economics are strong once you clear that step: Atlantic City Electric credits exported power at the full retail rate, and a second home that sits empty for much of the year exports a lot. The four companies below work South Jersey, and none of them is based in Cape May County, which we say plainly below rather than dressing a Camden County crew up as local.
The top solar companies serving Cape May, NJ are EMT Solar & Roofing, Impact Solar, SunnyMac Solar and Trinity Solar, based on EcoGen America’s vetting framework. EMT leads because it carries roofing craft in-house, and on Cape May’s aged, salt-exposed and often historic roofs the roof decision comes before the solar decision.
Our Top 4 Solar Installers Serving Cape May, NJ
Each company below was checked against New Jersey program records and its own stated terms, and ranked on what this specific market tests: roof condition, historic review, and a warranty that survives salt air. Placement is never sold.
EMT Solar & Roofing
The only company here that will re-roof and then mount, under one contract and one point of blame. That matters more in Cape May than almost anywhere in the state: a Victorian-era or salt-weathered roof that needs work inside five years should be replaced before the panels go on, not after. Two things to settle in writing before you sign: warranty claims across its materials range from 5 to 15 years, so count 5 until you have a number, and it has no NABCEP-certified staff.
Impact Solar
The most transparent paperwork of the four: it lists its home improvement contractor number, its electrical contractor business permit and its NABCEP installer certification on its own site, which is exactly the set a homeowner can check in ten minutes at the Division of Consumer Affairs. It names Cape May among the counties it covers, runs an in-house team led by the NABCEP-certified installer, and backs the work with 25 years on both workmanship and equipment. Smaller than the volume names, so ask about crew scheduling for a shore address in season.
SunnyMac Solar
Sixteen years in the trade with a New Jersey install record concentrated in the southern counties, and a 25-year warranty stated plainly across both equipment and workmanship rather than buried in ranges. On the larger inland lots north of the canal it will also quote a ground mount, which is often the honest answer when a historic roof cannot take an array the commission would approve anyway.
Trinity Solar
No company has built more residential solar in New Jersey’s program records, across all 21 counties and reaching back to 2003. In a town where the permit passes through a historic review before it is issued, having filed thousands of New Jersey permits is worth something real. The trade-off is service at scale: a heavy complaint file and warranty language that varies by page, with a 5-year floor across its own materials.
Said plainly: none of the four is headquartered in Cape May County. Impact Solar in Haddonfield and EMT in Cherry Hill are the closest at roughly 75 to 80 miles, and both name the county in their own service areas. A Cape May County operator that lists its license and its warranty term would lead this page, and we are actively looking for one. The rest of the state field is compared side by side in our guide to the best solar companies in New Jersey.

Before the Panels: Cape May’s Historic Preservation Review
Cape May protects one of the largest collections of Victorian buildings in the country, and the city runs that protection through its zoning code. A solar energy system needs a building permit from the Construction Code Official, and before that permit is issued the application is referred to the Historic Preservation Commission. The commission works from adopted design standards that cover solar panels alongside windows, sheathing and fences, and the test it applies is minimal visibility and compatibility with the district. The city won a $44,700 Certified Local Government grant in 2023 to update those standards, so an installer working from a memory of the old rules is working from the wrong document.
What that means for how you choose:
- Rear and side roof planes come first. A design that puts the array where the street can see it invites a longer review, so ask to see the layout from the sidewalk before you approve it.
- The roof gets judged before the panels do. Salt air ages a roof faster than an inland one. If the covering has under five years left, replacing it first is cheaper than removing and reinstalling an array later.
- Ask who has been through this commission. Not “do you work in South Jersey”, but whether they have taken a Cape May project through historic review and what the commission asked them to change.
The money side is Atlantic City Electric territory and it is genuinely good. Exported power is credited at the full retail rate under New Jersey’s 1-to-1 net metering, and every 1,000 kWh you generate earns an SREC-II certificate that the state’s SuSI program buys for $76.50, paid quarterly for 15 years, with the rate locked at the moment your registration is filed. A shore house that is empty on weekdays exports most of what it makes, which is exactly the profile full-retail crediting rewards. Fair New Jersey cash pricing runs $2.65 to $3.10 per watt, and the federal residential credit is no longer part of the arithmetic: Section 25D expired December 31, 2025.

Frequently Asked Questions
EMT Solar & Roofing, Impact Solar, SunnyMac Solar and Trinity Solar are the four installers we match with Cape May homeowners in 2026: EMT for roofing and solar under one contract, Impact Solar for license numbers on the page and a 25-year warranty on workmanship and equipment, SunnyMac for a South Jersey install record and ground mounts, and Trinity for the deepest New Jersey permitting experience. None is headquartered in Cape May County.
If your property is in the historic district, the application is referred to the commission before the building permit is issued. The commission judges panels against adopted design standards, weighing visibility from the public way and compatibility with the district, so plan for rear and side roof planes and build the review into your timeline rather than treating the permit as a formality.
Often more than on a year-round home, because New Jersey credits exported power at the full retail rate. A house that generates all week and consumes little banks credits that offset the weeks you are there, and the SREC-II certificates pay on generation regardless of whether anyone is home. Ask for the model run against your actual bills rather than an occupancy assumption.
Atlantic City Electric, not PSE&G. ACE runs its own interconnection process for the southern counties, so ask any installer for a recent ACE permission-to-operate reference rather than accepting general New Jersey experience as proof.
Before any sales conversation, review New Jersey’s incentives, benchmark bids against New Jersey pricing data, and read the payback math in our New Jersey worth-it analysis.
