Then, Renewable Funding purchases them and transmits the proceeds to individual property owners on demand, who then pay for the cost of the system minus the rebate granted by the state under CSI. The owner services the debt via a surcharge (First Special Tax) on its properly. Interest on the loan is attractive because Berkeley can secure longterm (20 years) low-interest debt through these dedicated bonds. The tax stays with the property even if the owner sells, although the owner would have to leave the solar panels. The First Special Tax, like other property taxes, will be secured by a lien on the property, which ranks senior to the first mortgage.
