We’ve talked to hundreds of New Jerseyans who have already gone through the solar panel installation process. Here’s what Trentonians should look for when choosing a solar panel installation company. We’ll also touch on overall costs and ways to save with government incentives.
A typical residential solar panel installation costs $25,284 in Trenton.

Jump to insightSolar scammers in Trenton may falsely claim to be affiliated with a Mercer County or New Jersey government agency.
Jump to insightA typical solar panel installation costs anywhere from $9,450 to $27,000 in New Jersey. Prices in Trenton are comparable, ranging from $9,485 to $27,100. On the high end, Ryan in Voorhees took out a $35,000 loan to go solar.
System size is a major solar cost factor. It also depends on if you want an energy storage battery, which sometimes costs as much as the panels: $7,000 to $18,000. A battery lets you store excess energy generated during the day and use it when your panels aren’t producing, like at night or during outages. It’s worth considering if your area gets frequent blackouts or if you don’t opt into Trenton’s net metering program.
Average solar panel installation costs by system size in Trenton
5 kW | 6 kW | 7 kW | 8 kW | 9 kW | 10 kW | |
---|---|---|---|---|---|---|
Before federal tax credit | $13,550 | $16,260 | $18,970 | $21,680 | $24,390 | $27,100 |
After federal tax credit | $9,485 | $11,382 | $13,279 | $15,176 | $17,073 | $18,970 |
Getting solar panels is like buying a car. Most people pay cash, finance or lease. Similar to leasing, a power purchase agreement (PPA) lets you get the benefits of solar without actually owning the equipment.
» SOLAR PANELS: Buy vs. lease
Solar panels are generally worth it in New Jersey if you like the idea of lowering your monthly utility bills. On average, Trenton homeowners with solar panels can avoid $60,218 in total utility costs over 25 years.
One resident, Eric in Jackson, told us their utility only charges about $30 to $70 each February, “and that’s it. I love solar. Saving me so much money.”
The main drawback is the high upfront cost of purchasing and installing the panels and equipment. Assuming an upfront purchase, it takes about 8.5 years to break even (when your savings with solar panels make up for the cost).
Considering New Jersey averages 3.5 to 4 peak sun hours each day, switching to solar is also worth considering for the environmental benefits. We suggest using NREL’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house. Project Sunroof is a reliable online solar savings estimator.
Potential roof problems
As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels again. Velissa in Willingboro said it cost $8,600 to remove and replace shingles. Sounds like an expensive and frustrating process — avoid it if you can.
» SHOULD YOU: Replace your roof before going solar?
In our experience, the best solar companies in New Jersey have a few things in common: lots of experience, reliable equipment and transparent contracts. Here are some hiring tips.
Going solar in Mercer County
Scammers sometimes pretend to be associated with the government or local utility. The State of NJ nor the Board of Public Utilities offer a completely free solar panel installation program, according to the New Jersey Clean Energy Program.

The 30% federal solar investment tax credit (ITC) is the best incentive for most Trenton homeowners. It reduces your federal tax liability by 30% of how much it costs to install solar panels. Don’t get confused: The ITC is a credit, meaning it directly decreases the amount of taxes you owe. This is different from a deduction, which lowers your taxable income.
The ITC drops to 26% in 2033 and 22% in 2034.
You can combine the ITC with local solar incentives in New Jersey to maximize savings.
For instance, the Successor Solar Incentive (SuSI) program is a performance-based incentive that pays for energy production over time. There’s a sales tax exemption, which saves about 7% on the equipment. Plus, a property tax exemption means your property tax bill won’t go up if solar panels increase your home’s market value.
The average Trenton household needs a system with a capacity of 9.33 kW (kilowatt) to fully offset their electricity costs. Depending on how much energy you and your family use, you might need a smaller or larger one.
Net metering is a system of give-and-take between you and your utility company. You also earn credits for sending any excess solar energy to the grid. Net metering also lets you access power from the grid when your panels don’t generate enough electricity.
Trenton is primarily serviced by PSEG, which has its own set of rules within the state's framework. Typically, you get credit for excess solar generation at the same rate you pay for electricity. This is a major advantage.

Yes, solar installations are considered electrical tasks, so there are permitting requirements by the City of Trenton.
Monocrystalline and polycrystalline are the most common types of solar panels used in residential installations. In general, monocrystalline panels are considered the best bang for your buck. Cheaper solar panels are typically polycrystalline. The key difference is in materials and efficiency: Monocrystalline panels use pure, single silicon crystals, while polycrystalline panels are made from melted silicon fragments, resulting in different efficiency levels.
Solar panel efficiency is a measure of how well a panel makes electricity. Standard efficiency rates range from 19% to 23%, which means 19% to 23% of the sunlight that hits the panels gets converted into electricity. The more efficient your solar panels are, the fewer panels you need. While more efficient panels cost a little more, you save by buying fewer panels.
The ConsumerAffairs Research Team used a research-backed, data-driven approach, which was informed by our expert editors, to choose the best solar companies. We prefer to recommend those with a longer time in business and a solid track record of reliability in Trenton, New Jersey. For this guide, we objectively weighted several key features to get our final rankings:
Reviews, ratings and testimonials: 40%
We analyzed solar company reviews by verified solar customers to gauge real-world satisfaction. Companies with generally positive feedback on our site scored highest in this aspect. Those with the most 4- and 5-star reviews by verified Trenton customers were given preference.
Warranties: 20%
A long warranty is important — it shows that a company stands behind its products and services. We compared companies on both equipment and craftsmanship warranty terms. All of our top picks for professional installation have warranties or production guarantees of at least 10 to 25 years.
Equipment selection: 20%
We evaluated each company’s selection of solar panels, storage batteries and inverters. Those with proprietary technology or a wide equipment selection from trusted brands ranked highest.
Financing and payment options: 20%
