The electricity you produce is equal in value to the electricity you receive from SIEA. If your solar array produces one kWh of electricity, you can directly reduce your electric bill by one kWh. If that kWh of solar electricity is generated when you don’t need it, it will be stored in your SIEA kWh bank and rolled over month to month. Your consumption will always be used out of your kWh bank first and is cashed out yearly in May at current SIEA avoided costs
