Solar Panel Cost in New Jersey (2026)

New Jersey consistently ranks among the top five states for solar installations despite its modest sunshine compared to Sun Belt states. The key driver is economics: New Jersey has some of the highest electricity rates in the country at $0.17 to $0.22 per kWh, making solar savings substantial. The state Successor Solar Incentive Program (SuSI) provides ongoing payments for solar electricity production over 15 years, while the sales tax and property tax exemptions eliminate two of the largest hidden costs. In 2026, New Jersey solar installations cost $2.70 to $3.50 per watt, with the densely competitive installer market in North Jersey, Central Jersey, and the Shore offering aggressive pricing. Combined with the federal 30% ITC, New Jersey solar systems achieve some of the fastest payback periods in the nation at just 6 to 9 years.

New Jersey Solar Incentives and Rebates

Federal Investment Tax Credit (ITC): New Jersey homeowners claim the 30% federal credit, reducing a $19,800 system to about $13,860.

Transition Renewable Energy Certificates (TRECs): New Jersey Successor Solar Incentive Program (SuSI) pays solar system owners for each MWh of electricity produced. Residential systems under 25 kW earn payments for 15 years.

Sales tax exemption: New Jersey exempts solar panels and installation from the state 6.625% sales tax, saving approximately $1,310 on a typical system.

Factors That Affect Solar Costs in New Jersey

System size: Larger systems have lower per-watt costs. A 10 kW system in New Jersey costs less per watt than a 5 kW system due to fixed installation costs being spread across more panels.

Panel quality: Premium panels from manufacturers like REC, Panasonic, and SunPower produce more energy per square foot but cost 15 to 30% more than economy panels. The higher upfront cost is often justified by better long-term production and warranties.

Roof complexity: Multi-story homes, steep roofs, and roofs with dormers or vents increase installation time and cost. Simple single-story roofs with south-facing exposure are the most affordable to equip with solar.

Installer competition: Areas with many competing solar installers tend to have lower prices. Getting at least three quotes ensures you find competitive pricing in your area.

Permitting and interconnection: Permit fees and utility interconnection timelines vary across New Jersey. Some municipalities have streamlined solar permitting, while others require longer review periods.
