Solar FAQ

Answers to some of the questions you might ask about GMP Solar Power.

What is GMP Solar?

GMP Solar is a net metering program that credits customers who generate solar energy. The amount a customer receives is based on the value of the energy that GMP charges the customer, plus an additional incentive for every kwh generated of 5.3 cents for installations less than 15 kw, and 4.3 cents for installations larger than 15 kw.

Who is eligible to take advantage of GMP Solar?

Any Green Mountain Power customer with metered service may participate. 

I already have solar panels installed. What do I need to do to take advantage of GMP Solar?

To measure the amount of solar generation, an additional meter needs to be installed, separate from your existing meter. This meter will need to be installed on the outside of your building.

What do I need to do to take advantage of GMP Solar if I don’t yet have solar?

Once you have decided to install solar generation, you must apply for a Net Metering Certificate of Public Good from the Vermont Public Service Board. As mentioned above, an additional meter will need to be installed to directly measure the output of the solar generation.

Our Guide to Customer-Owned Generation and Distributed Resources is a great resource to help you get started.

You can also find the answers to many of your questions at Renewable Energy Vermont's website,

How do I get paid for the solar generation?

Each month, you will see a separate line item on your bill, showing the dollars you earned for your solar generation that month. Your normal usage line will be reduced by the amount you generated.

Do I need to follow the State of Vermont Net Metering Rules and Laws?

Yes. You must have a Certificate of Public Good for Net Metering from the State of Vermont Public Service Board.

What if I generate more than I use?

If your system produces more power than you use in a year, it is likely that you will be creating excess net metering credits on an ongoing basis. Starting on June 1, 2016, as required by Vermont law, excess net metering credits that are more than one year old will expire. To avoid losing these credits we suggest you form a group or add members to an existing group. For information on how to do this, visit Customer-Owned Generation and Distributed Resources.
