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.
