10 Solar Installation Mistakes That Will Ruin Your Investment
May 9, 2026Can You Power Your Whole Home With Solar Panels?
May 9, 2026The short answer for most NJ homeowners: yes, solar is a strong investment — typically better than a home renovation, often better than a bond portfolio. Here’s how to run the numbers yourself.
The Basic ROI Formula
Payback period = Net system cost ÷ Annual savings. If your system costs $28,000 and saves you $3,500/year in electricity plus $900/year in SRECs, your annual benefit is $4,400 and your payback is 6.4 years. After that, 18+ more years of essentially free electricity.
What Goes Into Annual Savings
Annual savings = (kWh produced × utility rate) + SREC income. A 9 kW system in NJ produces roughly 10,800 kWh/year. At $0.19/kWh that’s $2,052 in direct savings. Add $900 in SREC income and you’re at $2,952/year. Every 1¢ rise in utility rates improves your return.
NJ-Specific Advantages
New Jersey has some of the highest electricity rates in the US, making solar savings more valuable here than in low-cost states. The SREC program adds a second income stream that most states don’t offer. Property tax exemption on the added home value means a higher appraisal with no higher tax bill.
The 25-Year Picture
Assuming 2% annual electricity rate increases, a $28,000 system in NJ typically delivers $70,000–$90,000 in total savings over 25 years. That’s a 2.5–3.2x return on investment — and unlike stock market returns, it’s predictable and backed by a physical asset on your roof.
What Hurts the ROI
An oversized system that produces more than you can use or sell back at full credit. An undersized system that still requires significant grid purchases. A lease that strips out SRECs and home value gains. A high-price installer charging $4+/watt.
