Get answers to common questions about home solar services in Princeton Junction, New Jersey.
A typical residential solar system in Princeton Junction ranges from $15,000 to $30,000 before incentives, depending on system size and home energy needs. Crucially, New Jersey offers strong incentives, including the federal Investment Tax Credit (ITC), exemption from the 6.625% state sales tax on solar equipment, and the NJ Clean Energy Program's Successor Solar Incentive (SuSI) which provides performance-based rebates. These can reduce your net cost by 40-50%, making solar highly affordable.
New Jersey's climate is excellent for solar, with sufficient sunshine to make systems highly productive. Princeton Junction experiences four distinct seasons; panels produce the most energy in sunny spring and summer months, while shorter winter days and potential snow cover reduce output. However, modern panels are efficient in diffuse light, and snow usually melts quickly off the slick surfaces, with annual production more than adequate to offset your energy use.
Installing solar in Princeton Junction (within West Windsor Township) requires a building permit from the Township's Construction Office to ensure structural and electrical code compliance. You must also submit an application to your utility provider, PSE&G or JCP&L, for interconnection to the grid to receive net metering credits. A reputable local installer will manage this entire permitting process for you, navigating the specific requirements of the township and utility.
Prioritize local, established installers with strong reputations in Mercer County, as they understand West Windsor Township's permitting process and have relationships with local inspectors. Verify they are NJ-licensed electrical contractors, check reviews on platforms like Google and EnergySage, and insist on multiple detailed quotes. A trustworthy provider will offer clear explanations of NJ's SuSI program, net metering, and provide robust warranties.
New Jersey has a robust net metering policy, which is crucial for maximizing your solar investment. When your panels produce excess energy, it is sent to the grid, and your utility (PSE&G/JCP&L) credits your account at the full retail rate. You can then use these credits to offset energy drawn from the grid at night or on cloudy days. Credits roll over monthly, and an annual "true-up" settlement ensures you get full value for your solar production.
