Introduction to Rooftop Solar PV Systems

Rooftop solar photovoltaic (PV) systems are decentralized energy generators installed on the roofs of homes, businesses, and industrial buildings. These systems use solar panels to convert sunlight into electricity, providing an on-site source of renewable energy that can either be used directly by the building or fed back into the electrical grid.

The key components of a rooftop solar PV system include:

Solar Panels: These are made up of photovoltaic cells that capture sunlight and convert it into direct current (DC) electricity.

– Inverters: They convert the DC electricity generated by the solar panels into alternating current (AC) electricity, which can be used to power appliances and other devices.

– Mounting Systems: These secure the solar panels to the roof, ensuring optimal positioning for sunlight exposure.

– Monitoring Systems: Used to track the performance of the solar panels, including energy production and system efficiency.

Rooftop solar PV systems rely on the photovoltaic effect. When sunlight hits the solar panels, the photovoltaic cells convert light (photons) into electrical energy by dislodging electrons. This creates a flow of electricity, which is then converted from DC to AC by the inverter, making it usable for typical household or industrial appliances. Any excess electricity generated by the system can be stored in batteries for later use or fed back into the grid, often earning credits or reducing utility bills through net metering programs.
