Local Installation Prices

So, how much does it cost to install solar panels in NJ? It’s impossible to provide an exact figure as system size, panel efficiency, installation labor, and state and local incentives affect the total cost.

Solar Panel Cost Per Watt in NJ

Solar panels are priced according to how many watts (power) they produce. This is calculated by dividing the solar system’s total cost by its total wattage. In New Jersey, most medium-sized homes need a 5-kilowatt system, typically 20 solar panels, costing roughly $2.75 per watt. 

  • $2.75 x 5000 = $13,750 (there are 5000 watts in 5 kilowatts). 

However, the total cost will be less than $ 13,750 once you apply tax credits. You may also need to install fewer panels depending on your home’s size and power needs. 

See the cost range for the most common solar panel system sizes below:

System Size Panels Needed Average Cost
2kW 5-8 $4,460-$5,740
3kW 8-12 $6,690-$8,610
4kW 10-16 $8,920-$11,480
5kW 13-20 $11,150-$14,350
5kW 15-24 $13,380-$17,220

Solar Panel Cost Per Square Foot in NJ

Home size is another factor affecting solar panel costs along with installation prices. Yet, there are ways to offset the cost of large solar panel systems. You can power specific energy-intensive systems like air conditioning with solar and keep the rest of your home on the traditional power grid.

Or, you can install a solar battery storage system to store excess energy during the day and take advantage of the state’s Net Metering Program that allows you to sell extra energy to utility companies.

Below is the average cost of solar panels based on home size:

House Size Average Cost
1,000 sq.ft. $4,460-$22,960
1,500 sq.ft. $5,740-$26,760
2,000 sq.ft. $8,920-$28,700
2,500 sq.ft. $13,380-$34,440

Average Solar Panel Cost by System Size

The larger your system, the more solar panels and inverters you need, which increases costs. The location of your home also plays a part, as solar panels in sunny areas produce more electricity than those in cloudy areas.

See average prices of how much solar panels cost in NJ according to size:

System Size Average Cost Number of Panels Panel Size
1kW $14,250 16 300 watts each
8kW $27,500 32 300 watts each
10kW $40,750 48 300 watts each
12kW $54,000 64 300 watts each
14kW $67,250 80 6.1 years

Other Factors Affecting Solar Panel Installation Costs

Are solar panels in NJ worth it? Yes, long-term, they are. However, there are many contributing cost factors to consider when investing in solar energy, such as the installation, ownership, and panel maintenance. Knowing them upfront will help you budget correctly.

Factor Details
Home Insurance

Installing solar panels will likely lead to an increase in your homeowner's insurance premiums. However, this can vary depending on the type of coverage you select. Double-check with your insurance provider to be sure.

Home Location

In climates with frequent storms, high winds, snowfall, and heavy shade, solar panels may still generate electricity, but their efficiency will be reduced.

Owning vs. Renting

You receive all available tax credits and rebates if you own solar panels. Leasing them from a company is also an option, which is lower maintenance but doesn't come with any financial perks.


When choosing a solar panel brand, you’ll want to consider panel efficiency, warranty, and cost. As with most things, you get what you pay for. For example, a more expensive brand may have a better warranty and less degradation.

We recommend researching specifications from top manufacturers to identify the best value or consult with Solar ME - we’re more than happy to offer guidance.

Generally, we work with several highly-rated brands, including:

  • Rec: Our top recommended brand for high quality and efficiency.
  • Silfab: Known for high quality, durability, and 30-year warranties.
  • Panasonic: A premium brand for discerning customers.
  • Qcells: An innovative brand pushing solar technology.
  • Phono: A more affordable option for budget-conscious consumers.

Type of Solar Panels

Along with different brands, there are also different types of solar panels: polycrystalline, thin film, and monocrystalline.

  • Polycrystalline: Made from tiny silicon crystals that give the panels a blue hue, polycrystalline is more affordable but less efficient compared to monocrystalline panels.
  • Film: These solar panels are made from a thin layer of silicon or other semiconductor material. Although they are the cheapest, they are also the least efficient.
  • Monocrystalline: Arguably the best type of solar panel, monocrystalline panels are made from a single silicon crystal, making them thinner and blacker in color. They are the most expensive type but generate the highest energy yields.

Roof Condition

When considering solar panel installation, asphalt shingle roofs in good condition, ten years old or younger, are usually the most suitable choice. Other roof materials like tar and gravel do not make good foundations for solar arrays. 

Additionally, it's essential to have your roof inspected and repaired by an experienced professional if it is older than ten years, as age can affect its suitability. Doing any necessary roof repair before installing solar panels will save you the hassle of dealing with unexpected issues down the line.

An experienced solar installer will help you determine if your specific roof type is compatible and what next steps you should take if it isn’t.

Installer Margin

Choosing the right solar installation company is critical to getting the most value from your solar panels. Local, smaller companies may cost more for installation but offer personalized options, discounts, better customer service, and faster responses to any issues that arise after installation.

They are also much more invested in your satisfaction, as their business relies heavily on word-of-mouth. Ultimately, the company's size affects the cost of the solar panels the most, making it essential to do your research.

The Operational Cost to Run and Maintain Solar Panels in NJ

Solar panels should be cleaned at least twice yearly to maintain peak performance. A quick visual inspection should also be conducted during these cleanings to check for any issues. More thorough inspections should be done every few years to check for component replacements or repairs.

On average, solar panel cleaning costs about $465. This may seem significant, but it is well worth the investment. Regular maintenance not only preserves the output and lifespan of your solar panels but identifies minor issues before they become larger expenses.

How to Save on Solar Panels in New Jersey

Not only does investing in solar energy in NJ significantly reduce your electricity bill, but it also plays a role in environmental conservation. Additionally, New Jersey has attractive incentives and policies that make going solar even more affordable.

The Federal Tax Credit

The Federal Solar Investment Tax Credit, also known as ITC or Residential Clean Energy Credit, offers an excellent benefit for those beginning their journey with solar energy. This tax credit gives a 30% reduction on the cost of solar panels and battery storage and is guaranteed to remain that way till 2032, thanks to the Inflation Reduction Act.

New Jersey State Incentives

In addition to the Federal Tax Credit, the state of New Jersey offers a number of incentives and rebates:

How to Apply for Net Metering and Other Incentives

If you are interested in net metering and other solar incentives, you must reach out to your local utility company to learn about their application process. Every utility company has different requirements and procedures for applying.

New Jersey Tax Exemptions

If you are considering installing solar panels, be sure to take advantage of the tax exemptions for solar energy in NJ.

  • Property Tax Exemption: These exemptions are worth up to $3,000 per year for homeowners and $10,000 per year for businesses. To qualify for the solar property tax exemption:
    • You must own the solar panels.
    • The solar panels must be installed on your primary residence or place of business.
    • The solar panels must be connected to the electric grid.
    • The solar panels must be generating electricity.

How to Apply for The New Jersey Tax Exemptions

You can apply for either tax exemption by filing an application with the appropriate authority. The application process for the property tax exemption is handled by your local tax assessor, while the application process for the sales tax exemption is dealt with by the New Jersey Department of Taxation
