Solar energy is converted into electrical energy through the use of photovoltaic cells12345. When sunlight shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel, creating electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow1. The photovoltaic cells absorb sunlight, triggering the photovoltaic effect to generate an electric current, which is then converted from direct current (DC) to alternating current (AC) using a solar inverter3. The electricity can then be supplied to homes and devices, often storing excess energy in solar batteries for nighttime use3.
