Abstract: A system and method for recorded renewable energy certificates from power produced by small power generators is provided. An appliance can include a renewable energy source and electronics to monitor and control the charging of batteries in the appliance utilizing power from the renewable energy source. Power from the batteries can be utilized to power or charge external devices. The electronics also records the total power production from the renewable energy source and uploads transaction records to either an external device for transmission to a records server or uploads it directly to the records server itself. The records server compiles the transaction records and generates renewable energy certificates by aggregating the transaction records. Renewable energy certificates can be redeemed in exchange for real or virtual goods and services.

Abstract: A personal solar appliance (PSA) is presented that collects and stores solar energy. A method of charging a battery from a solar cell according to some embodiments is presented that includes applying power from a bootstrap circuit when the battery has a very low state of charge or the solar cell has output below a threshold; and applying power from a maximum power point circuit when the battery and the solar cell provide power above the threshold.
