While solar panels generate DC electricity, the grid operates using AC (alternating current) electricity. An inverter is needed to convert the electricity so that it can be used by the grid. For most of the past 100 years, electrical grids involved large-scale, centralized energy generation located far from. . How do Solar Panels generate electricity? Solar panels play a critical role in the process of generating electricity, using sunlight to produce electricity through the photovoltaic effect. Each solar panel contains multiple photovoltaic (PV) cells that capture sunlight and convert it into DC. . A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity. Sunlight is composed of photons, or particles of solar energy.
