There is a small fee each month to lease solar panels, but customers' electric bills with Green Mountain Energy will also be reduced based on the amount of electricity they produce at home - which is free to consume.

Texas customers also have the opportunity to earn 100% rebates for the excess energy they produce and sell back onto the grid. Similar programs are available for commercial customers.

For customers on solar power plans with Green Mountain Energy, $4 from each monthly bill goes to support new solar projects. Customers receive $11 bill credits for each new solar project established.

Smart Meters

Available for free to customers in Texas, the Nest Learning Thermostat provides information to consumers to help them reduce their energy use and save money. Services include automatically lowering home temperature when you are away, notifying customers when they are consuming energy efficiently, and historical electricity usage data for the past 10 days.
