Balance of System (BOS) components are the additional parts required to complete the photovoltaic system and ensure it operates safely and efficiently. These components include wiring, connectors, grounding equipment, junction boxes, surge protection devices, fuses, and breakers, as well as performance monitoring and metering equipment.
When these photons make contact with a PV cell, they transfer their energy to the electrons in the atoms of the cell''s material. These energized electrons break free from their atoms, creating an electric current. This process, known as the photovoltaic effect, is the basis of how solar energy is converted into electricity using PV systems.
Solar panels and photovoltaic cells (PV cells) refer to different parts of the same system. A PV cell is a single unit that contains layers of silicon semiconductors. When you exposed them to sunlight, loose electrons are freed, causing a current to flow. A solar panel is when several PV cells are combined together in one large sheet.
