With an expected investment cost of $sim$$100 trillion within the next decades, renewable energy is at the heart of the United Nation's transition to net-zero emissions by 2050. Unfortunately, there are several challenges associated to these investments, such as the low exit liquidity and the hassles of going through centralized agencies. Investments in renewable energy is thus currently mostly limited to governments, corporate, and wealthy individuals. At Peer2Panel (P2P), we address these issues by tokenizing solar panels into unique SolarT NFTs on the Ethereum blockchain, where we function as an intermediary between a token-owning individual and a physical solar panel. Apart from panels installation and maintenance, our role is to redistribute the profits from the generated energy to the SolarTs holders, thus making investments in SolarTs transparent, democratic, and liquid. In fact, ownership of a SolarT token gives a direct ownership interest in the solar panels owned by P2P, which can then be exchanged freely on-chain and thus remove most of the hassles of the traditional energy market. In addition, P2P leverages the most recent innovations from the decentralized finance (Defi) ecosystem to propose SolarTs-collateralized loans, instant liquidity and multi-chain interoperability to its investors.
