What You Need to Know

Other Benefits:

Besides earning a financial return of 22-35% for the first 10 years, it will also reduce pollution and CO2 emissions and dependence on fossil fuels.

Maintenance Requirements:

Since we're doing a pre-paid lease there shouldn't be any maintenance requirements for the first 20 years.

My Motivation:

We were motivated by cutting back on fossil fuel use and pollution emissions, but it turns out that the financial rewards are equally worthwhile.


Do it soon because the tax credits, rebates and SRECs may not be around for very long and I don't think the price for installation of PV will decline much more than it already has. Instead of waiting, you'll be earning 22-35% annual returns on your investment. Make sure the installer you select gives you the SRECs. That's where the real money is.

Experience with Installer:

Independent Power Systems is great. They took the time to measure the roof and check the structure before they bid on the job. Then the installation went very smoothly. Please tell them I sent you.

Additional Notes:

Our condo is half of a 2-family so our neighbors and we installed identical systems at the same time which helped bring the price down.
