Yes. Households with solar still have to pay their utility’s grid connection fees, as well as a small customer benefit charge. In all likelihood, your costs for electric will be significantly reduced based on your system’s production that month.
Eventually, when your system is paid off, you will still be responsible for the small grid connection fee and in rare cases, any excess energy used beyond your system’s capabilities as needed. *Solar production varies based on factors such as system size and weather conditions.
