The Best Solar Companies in New Jersey Options


With 130 miles of coastline and over 200 days of sunshine per year, it’s no surprise that New Jersey ranks eighth in the country for solar. By installing a solar array, Garden State residents can benefit from reduced energy bills and reduce fossil fuel dependency. But solar is a fast-growing industry, and it’s wise for homeowners to research their options before signing a contract with a solar company in New Jersey. Here, we’ve compiled a list of the best solar companies in NJ, along with some tips to help New Jersey homeowners navigate the solar installation process.

What to Consider When Choosing One of the Best Solar Companies in NJ

There’s a lot to consider when considering installing solar and shopping for one of the best NJ solar companies to do the job. Here, we’ve highlighted some of the most significant factors homeowners from Howell to Hoboken will want to consider during this process.

Home Location and Roof Type

The first consideration for a homeowner thinking about installing a solar array is their home—specifically, the direction their home faces, the angle of the roof, and the roof material.

In the northern hemisphere, it’s ideal to install solar panels on a south-facing roof. Because of Earth’s tilt, the sun travels in a slightly southern path, not straight across the sky. A south-facing roof ensures that a home receives the maximum amount of sunlight year-round. Southeast and southwest are the next best possibilities for a home’s direction, as those roofs will still capture some of the southerly path of the sun. However, it’s not impossible to mount panels on roofs facing other directions; the power generation may just not be as optimal.

A 30- to 45-degree mounting angle ensures optimal sun exposure for solar panels. If a roof is flat, solar panels are typically mounted on a bracket that tilts the panels up to 30 degrees. Extremely steep roofs can still have solar panels mounted, but it may not be possible for the panels to capture enough sunlight for the home to become energy independent.

It’s possible to mount a solar array on any kind of roof material—but some types may be easier to work with than others. Composite shingles are durable and hold up well to the installation process, and standing seams on metal roofs minimize the amount of drilling and modifications needed. Tile roofs can present a bit more of a challenge; since each tile has some irregularities, it may take more time (and cost more in labor) to install a solar array.

Type of Panels and Efficiency

The two main types of solar panels used for powering homes are monocrystalline and polycrystalline. Monocrystalline is more efficient (meaning it is able to turn more sunlight into usable electricity) but also more expensive, while polycrystalline is more affordable but compromises power production. It’s possible to tell the difference between the two by the color: monocrystalline panels will be pure black, while polycrystalline panels appear blue. The type of panel a homeowner opts for will ultimately come down to their budget and power-production goals. An experienced New Jersey solar installer can help guide a homeowner to the right decision.

One distinction to note is that the efficiency of an individual solar cell is not the same as the efficiency of a panel. A solar cell is part of a solar panel, and a cell could have over 40 percent efficiency on its own. However, entire panels will have lower efficiency. Monocrystalline panels typically max out around 23 percent efficiency, while polycrystalline panels reach an efficiency of about 16 percent. Researchers at the NREL (National Renewable Energy Laboratory) have created a solar panel with almost 40 percent efficiency, but this technology still isn’t ready for the public.

There’s another type of panel to note: thin film. These panels are (as the name suggests) thin, flexible, and lightweight, but they’re even less efficient than polycrystalline. Thin-film solar panels also have the shortest lifespan of 10 to 20 years compared to the 25-year-plus lifespan of their monocrystalline and polycrystalline counterparts. Because of their lower efficiency, more would be required to power a home fully—and most roofs won’t have the space to accommodate the number of panels required. However, thin-film panels can be used as supplemental power production and are beneficial for homes that have unusually shaped roofs that may not be suitable for traditional panels.

On-Grid vs. Off-Grid

Another significant decision that homeowners have to consider when installing a solar system is whether or not they want the home to be connected to the local power grid. A home with a solar panel array still connected to the municipal grid is called on-grid or grid-tied. If it’s cloudy and the solar system can’t produce enough electricity to power the home fully, a grid-tied home can still pull power from the grid. However, if there’s a local power outage, the home can’t rely on its solar array—a grid-tied home will also experience an outage. This is a safety precaution so that electricity is not flowing into lines that utility technicians may be working on.

Off-grid homes are completely energy independent, meaning they’re responsible for generating all the power the home needs. Off-grid homes often rely on solar batteries to store excess energy and power the home during the night or when there’s cloud cover. They’ll also rely on one of the best solar charge controllers to regulate energy flow. Off-grid homes can still have power if there’s a local outage. However, the home will be without power if the batteries are depleted and the panels can’t produce any electricity.

Some regions and homes are better suited for off-grid solar systems than others, and an experienced solar installer can help homeowners make the decision.

Financing, Rebates, and Tax Incentives

The average cost to install a solar system in New Jersey is about $15,000, and not every homeowner has that lump sum of money readily available. The financing options available to a homeowner will, in part, depend on where they live. In New Jersey, homeowners have three financing options: a solar loan, a solar lease, or a power purchase agreement (PPA).

  • Solar loan: A homeowner borrows money from a lender or solar developer to purchase and install a solar system. In this situation, the homeowner owns the system, but it’s still subject to a lien or lender security interest. Homeowners with one of the best solar panel loans are eligible for tax incentives. However, not every homeowner will be eligible for a loan, and the homeowner is totally responsible for any maintenance costs.
  • Solar lease: A homeowner enters into a contract with a solar leasing company or developer. The homeowner makes regular payments and, in exchange, receives the energy the panels produce. Some contracts may require the homeowner to make a down payment. At first, the lease payments are often less than the value of the power being generated. However, payments for solar leases often escalate as time goes on. Eventually, the cost of the payment may be greater than the value of the power being produced. This option is attractive because there’s little to no up-front cost and the solar developer is in charge of any maintenance. However, homeowners may not be eligible for tax incentives, and there may be restrictions if a homeowner wants to add new construction (e.g., if the homeowner wanted to build a new addition that would block the panels from getting light).
  • Power purchase agreement (PPA): A PPA is similar to a solar lease. The solar company buys and installs the solar system, and the homeowner pays the company per kilowatt-hour (kWh) for the energy that’s produced. A homeowner typically pays less for the solar energy than they would buying the equivalent amount from the utility. However, the PPA rate generally increases over time. The advantages and disadvantages are similar to those of a solar lease.

Solar panel installation in NJ can be made even more affordable with federal and state tax incentives.

  • Federal investment tax credit (ITC): For solar systems installed between 2023 and 2032, homeowners are eligible for a 30 percent tax credit. So, for example, if the solar system cost $10,000, the homeowner can obtain a $3,000 reduction on their federal income taxes. Solar leases and PPAs do not qualify for this credit.
  • Net metering: Homeowners are able to sell excess power back to the energy company in New Jersey.
  • Solar sales tax exemption: Home solar systems are not subject to New Jersey’s 6.625 percent sales and use tax.
  • Property tax exemption: The installation of solar panels does not raise a homeowner’s property taxes.
  • Successor Solar Incentive (SuSI) Program: For every megawatt-hour (mWh) a home solar system creates, the homeowner earns one solar renewable energy credit or certificate (SREC). Homeowners can then sell these credits to utilities. Utility companies have to buy a certain amount of SRECs per year to meet state sustainability guidelines. Solar leases and PPAs do not qualify for this program.


Like traditional home improvement projects, solar arrays often come with a labor warranty to cover any issues resulting from the actual installation work. These labor warranties can last anywhere from 10 to 25 years. The panels themselves will also come with a manufacturer warranty, often for about 25 years. Finally, many solar companies in New Jersey offer a power- production guarantee, wherein the solar system is guaranteed to output a certain level of energy for the guarantee term, often 20 to 25 years.

Customer Support

Top-rated solar companies with multiple avenues of customer support often have higher customer satisfaction rates, as it’s easier to get in touch with a representative when there are questions or issues. Offering customer support over the phone is standard for many of these companies, but sometimes it can be difficult to get a real person on the line in a timely fashion. Some customers may prefer to email the company so there is a digital paper trail of conversation.
