Your needs are evolving. Your energy should too.

A growing family, hotter summers, or that new EV. Energy needs tend to go up and up. A traditional solar energy system might meet your needs today, but once you start using more energy, you'll have to pay the utility.

        FAQs

        It’s pretty simple. For customers who think they’ll increase power (which is typically what happens after going solar) Flex provides a ton of value. We don't recommend Flex to customers who know their usage will be going down or staying the same - for example, if your family is moving out, or if you know you're living elsewhere part time. 

        Sunrun doesn't own the additional energy your system produces. It's yours to use or export. If you are exporting that additional energy to the grid, the exact treatment for those exports depends on your state and utility.

        You should always expect to have at least a small utility bill. Even when solar offsets all of your energy needs, the utility will still require base fees for being connected to the grid. You’ll also pay for any energy you need beyond what your solar covers. This can change over time if the way you use energy - or when you use energy - changes. The great thing with Flex is it helps keep future utility costs low as your usage needs increase.

        Your utility bill is based on how much electricity you import from the utility and anything you send back from your solar. As you use more energy, you may also import more electricity from the grid. This would increase your utility bill.

        We estimate your usage based on the previous 12 months of your utility bills.  We take this

        annual number and divide it by 12 months to arrive at your levelized monthly pre-solar consumption.  We then size your System based on information you share with us your anticipated growing energy needs. 

        If 12 months of past utility bills were not available, we use your home's square footage to determine your Estimated Current Usage.

        You can carry over Rollover credits from one year to the next up to your Flex Monthly Baseline * 12.  You cannot carry over credits that bring you below your Flex Monthly Baseline * 12. As an example – if your pre-solar usage is 12,000 kWh, you have consumed 12,400 kWh and have -200 kWh in Rollover credits, those credits will carry over to the next year. If you consumed 11,800 kWh and have -200 kWh in Rollover credits, none of those credits will carry over to the next year.

        At the end of every 12-month period, Sunrun looks at (1) your annual pre-solar usage (used to calculate Flex Monthly Baseline); (2) the number of kWh charged at the Flex Rate; and (3) the total kWh produced by the System. If (3) - (1) is less than (2), you will receive an annual production adjustment, which is called our Flex Guarantee!
