The cost of solar power depends on the number of panels installed and whether your site is suitable for rooftop solar or ground-mounted solar. Ground-mounted systems typically cost more. On average, rooftop solar panels cost between $10,000 – $25,000.
In addition to the campaign discounts, Solarize NOVA will help participants access the 30% federal tax credit and any local incentives, connect to affordable financing, and navigate the Solar Renewable Energy Credit (SREC) market. For more information, visit our Incentives and Financing page.
For a monthly cost equal to packing your lunch a time or two each month for a few years, you could be investing in a valuable asset that generates clean, renewable power starting today – and is generating a positive cashflow within about 10 years. This information is true if you are borrowing for an installation. If you are paying cash, these systems are paid off in less than 12 years – better than an 8% average annual return on investment.
A Sample of Pricing for a Small Solar System
A very small array of 3000 watts (3kW) – about 10 panels – should produce some $420 worth of electricity a year at today’s energy prices. At $2.50 per watt, the installation cost is $5,250 after the federal tax credit. If your current electric bill averages $120/mo, a 6000W array should cover about 60% of that on a good site. A good site is critical. You want the array to face somewhat southerly and to be in full sun. Roofs can be great. Yards, fields, and parking lots work too. See more details below.
|Price per watt ($/W)|
|System location||Roof Mount||Ground Mount|
|Standard Panel + string Inverter or microinverter/DC optimizer||2.50||2.45||2.40||2.95||2.90|
