Photovoltaic (PV) circuit boards are key components in solar energy systems, converting sunlight into usable electricity. Composed of silicon-based solar cells, these boards utilize the photovoltaic effect: photons from sunlight knock electrons loose in the silicon, generating a direct current (DC). This DC power is then converted to alternating current (AC) via inverters for household or industrial use. Lightweight, durable, and environmentally friendly, PV boards require minimal maintenance and operate silently. They play a vital role in renewable energy solutions, reducing carbon footprints and dependence on fossil fuels. Widely applied in rooftops, solar farms, and portable devices, they symbolize a sustainable shift toward clean energy.
