Solar Energy FAQ’s
Do solar systems really work in Vermont?
Yes, absolutely! People have been installing solar energy systems in their homes and businesses in Vermont for over 40 years. A grid-tied, net-metered solar electric system (PV or photovoltaic) can be sized to produce enough electricity to power 100% of your electrical needs!
How much do a solar systems cost?
Solar systems are custom designed to meet the needs of each individual household or business. Each site has unique installation design requirements. It isn't possible to quote an exact price based on one size fits all, but a typical solar power installation will pay for itself in full in about ten years and continue to produce free electricity for many decades to come!
The federal solar income tax credit of 30% and GMP's net-metering program help make solar power affordable for Vermont solar customers.
Photovoltaic systems are priced according to the size of the system and the type of installation (tracker, rooftop, or fixed ground mounted).
How long do solar systems last?
Solar power systems are still working that were installed more than 25 years ago! They require very litte maintenance and will continue to produce power for many decades. The updated technology and high quality equipment that Solar Pro installs is designed to last much longer than solar systems that were installed in the '70's and '80's. We expect the new systems to last as long as 50 years or more! Most of the PV panels that we install have manufacturers' performance guarantees up to 80% of their original output for 25 years.
Will my solar system work in the winter?
Yes, just as soon as the sun comes out after a snow event, your solar panels will start to produce power. Even on cloudy days, solar systems generate electricity in dim light. It’s true that solar systems work most efficiently during summer months, but they will continue working to provide solar energy for your home all year long.
I live on the side of a mountain and my house is shaded part of the day. How much sunshine do I need to make solar work at my location?
Almost every home in Vermont is a good candidate for solar power. To be most effective, the sun should shine on your solar panels from 9 a.m. to 3 p.m. If the sun sets behind your mountain as early as 4 p.m., you’re probably OK for solar!
I don’t have a south-facing roof, am I solar-challenged?
No way! A south-facing roof is an ideal location for solar installation, but is not required! Vermont's own AllSunTrackers produce 35%-45% more power than a fixed installation and are an excellent choice for many sites.
Do Solar Pro systems qualify for federal tax credits?
Yes, Solar Pro customers are eligible for the 30% federal income tax credit, based on the net installation cost of your new solar system, with no upper limit. Business solar customers may also take advantage of the tax advantages of accellerated depreciation and Vermont's 7.2% investment tax credit.
What are net-metering incentives?
Most Solar Pro customers are serviced by Green Mountain Power. Currently, GMP provides credits to solar net-metering customers on their electric bills in an amount equal to their current rate-per-kWh PLUS a bonus credit of six cents per kWh. Solar credits can be banked during solarific summer months to offset electric bills during the shorter, darker days of winter. If you have a large solarific roof or an open field for an AllSun Tracker system, you can earn an excellent rate of return by taking advantage of Vermont's Group Net-Metering program.
