How big is my Sunscription?

The size of your Sunscription is based on your annual historical energy use. This means that if you use more electricity, you will have a larger subscription, and if you use less electricity, you will have a smaller subscription. You can think of a large energy user as having more solar panels allocated to their subscription. Most subscribers have a Sunscription sized between 80-105% of their annual historical energy use, depending on the program and state guidelines. 

It is best for your Sunscription's estimated annual energy production to be proportional to your annual electricity usage. This allows you to maximize your savings while also limiting the need to budget for substantial seasonal variations in subscription payments and bill credits. Our team also intentionally sizes your Sunscription based on your utility's excess bill credit policy, so that you maximize your savings and don't lose out on credits that may expire on an annual basis. See below for information on how your utility treats excess credits.

How does my utility treat excess bill credits and what does that mean for my Sunscription size?

Illinois ComEd Subscribers

If you are a ComEd electricity customer and have excess Sunscription credits - or a credit amount that is greater than your total charges with ComEd – the credits will roll over and apply to charges in future months. ComEd subscribers are initially sized at about 90% of their annual historical energy usage to limit the accumulation of excess credits. Excess credits roll over indefinitely until they are either used up or until the customer leaves ComEd service territory, at which point any excess credit would expire.

Your utility does not share any information about changes in your electricity usage habits. If you think your electricity use has increased or decreased substantially, please share an electric bill with our team here. 

Illinois Ameren Subscribers

If you are an Ameren electricity customer and have excess Sunscription credits - or a credit amount that is greater than your total charges with Ameren – the credits will roll over and apply to charges in future months until April. In April, any remaining excess credit expires. Our team initially sizes Ameren subscribers at about 85% of their annual historical energy usage to limit the accumulation of excess credits and credit expiration. Subscribers whose Sunscriptions produce excess credits month over month most commonly do so in the summer when there is a high amount of energy production at the Solar Garden; these credits are then most often used up before April. Because solar energy production – and therefore bill credits – are lower in the winter and early spring, it is expected that very few if any Sunscriptions sized at 85% of a resident’s historical energy use would result in excess credits in the spring.

Minnesota Xcel Energy Subscribers

If you are a Minnesota resident in Xcel Energy territory, you don't have to be concerned about losing out on your Sunscription credits. Any excess credit on a single month's electric bill will apply to upcoming electricity charges, reducing your future electric bills. Most people "use up" the excess credit in the winter months when solar energy production - and credit accumulation - is lower. If you still have excess credits in the spring, Xcel Energy will cut you a check between March and May. To learn more about excess bill credits, see this article: I have a negative balance on my Xcel Energy bill. What does that mean?

Can subscription size be adjusted?

Depending on the capacity in the Solar Garden, we may be able to adjust your subscription size.

Most subscribers are sized between 80-105% of their initial annual electricity use. Some subscribers prefer to have their subscriptions sized larger to increase potential savings - as a reminder, if you're making a large payment to US Solar, you're receiving a larger bill credit on your electric bill too! While other subscribers prefer their subscriptions to be sized at or under their annual electricity usage because this reduces the seasonal variation in credits and payments and reduces the possibility of potentially losing out on excess credits. Depending on state guidelines, subscribers may be eligible to be allocated between 50% and 120% of their historical electricity use. If this interests you, please share an electric bill with our team and let us know what subscription size adjustments you'd like to consider. We will be in touch with you regarding state regulations, current capacity at your Solar Garden, and options to adjust your Sunscription size.
