Your relationship with your electric utility company will remain exactly the same if you enroll with Solstice, meaning you will continue to receive your electricity from your utility provider and pay those bills as you always have.
The energy produced by your local solar farm is directed back into the utility grid. In exchange for the energy produced by your share of the solar farm, you receive credits on your utility bill and then pay for that solar energy at a discounted rate to ensure you save money - that's where Solstice comes in!
