Solar Power 101 — Turning Light into DC and Connecting It to the Grid and Batteries
Solar power is a system that converts light into DC electricity at a photovoltaic cell's pn junction, then delivers it to loads or the grid via MPPT, an inverter, and a transformer. This piece organizes I-V characteristics, the effects of temperature, shading, and irradiance, grid interconnection, batteries, current equipment, and cutting-edge perovskite research, with equations and diagrams.
