Find your installer's price per watt (total price divided by system watts) to read your payback in New Jersey.

Questions about solar in New Jersey
How does New Jersey pay for solar power I send to the grid?
New Jersey is counted here as full retail net metering: each kWh you export earns the same as a kWh you would buy. We have not checked New Jersey's rules against its utility commission yet, and some utilities pay less, so check your utility's net metering tariff.
How much did the end of the federal tax credit change payback in New Jersey?
With the 30% credit that ended in 2025, the same system would have paid back in about 7.9 years instead of 11.3. The credit ended for systems installed after December 31, 2025. Leased systems and power purchase agreements can still pass on a business credit, but then you do not own the panels.
Is 1,305 kWh per kW a lot?
The range across states runs from about 922 kWh in Alaska to about 1,779 in the Southwest. Sunshine matters less than people expect: the electricity rate and how your utility credits exports move payback more.
