System Offset Notes

"SCL doesnt have a policy prohibiting a solar system from exceeding 100% of annual historical usage. However, excess generation will be retained as a kWh balance on their bill that rolls over until Mar 31, when we are required by law to clear the balance with no monetary compensation to the customer."
