Technical Design Report for a Photovoltaic Self-Consumption Installation with Surplus Injection
Abstract
This technical report documents a photovoltaic (PV) installation with self-consumption and surplus injection installed in Spain, which was designed for residential consumption and started up in an isolated single-family home with connection to the electricity distribution grid. Photovoltaic solar panels, inverter, lithium-ion batteries and a bidirectional meter have been integrated by this system. The report details the system’s technical requirements, energy flow, electrical calculations, economic analysis and compliance with Spanish regulations. Key words. Solar, battery, two-way, metering, self-consumption.
