Designing Smart Contract on a Blockchain Network for The Purpose of Trading Energy from Photovoltaic Power Plants

The emergence of clean energy sources, especially solar energy, has opened a new path for the world's energy supply. Providing energy in a secure and unmediated market is a concern for economic actors and experts in this field. Traditional and current markets provide energy as a third-party intermediary .Traditional markets have problems such as: lack of transaction transparency, failure to record the amount of specific subsidies, creation of a unipolar market, and human intervention, and therefore there is a need for a platform that addresses all of the aforementioned problems. Economic activists and electricity distribution companies thought of launching a blockchain-based platform in the energy market so that they could provide professional services, buy and sell energy on this platform. This article uses the Remix environment and the Solidity programming language to design a smart contract with the aim of realizing p2p transactions between the buyer and seller of solar energy of a photovoltaic power plant.
