SolarCoin is a digital currency rewarding solar energy producers. Inspired from Bitcoin and Blockchain Tech whereby transactions are recorded and validated by a peer to peer network of computers, SolarCoin presents the additional advantage of being coupled to a real-world asset: solar electricity. Each MWh of solar electricity produced by a photovoltaic installation awards one SolarCoin. Put another way, one can also understand that SolarCoin is Solar Miles for solarelectricity generation… and it’s free! What is the use of SolarCoin? In itself, a currency has a value assigned to it by a community of users, a social group, as a means of payment and value circulation. Additionally, SolarCoin has a social utility for its community: by rewarding the owner of a solar photovoltaic system, SolarCoin acts as an incentive, stimulating the implementation of solar power worldwide. SolarCoin may thus reduce the payback time for the solar installation as well as increase its returns.
