Photovoltaic (PV) Cells and the Photovoltaic Effect:

Solar panels consist of photovoltaic cells, typically made from semiconductor materials such as silicon. When sunlight (photons) strikes these cells, it excites electrons, causing them to move and generate an electric current. This phenomenon is known as the photovoltaic effect. The materials used in PV cells determine their efficiency in converting sunlight into electricity.

Inverter Conversion and AC Electricity:

The direct current (DC) generated by solar panels is then converted into alternating current (AC) through an inverter. AC is the standard form of electricity used in homes and businesses. The inverter plays a crucial role in the efficiency of the solar power system, ensuring that the electricity produced by the panels is compatible with the electrical grid and can be used to power appliances and devices in your home.

Net Metering and Grid Interaction:

Solar panels often produce more electricity than is immediately consumed. Net metering is a system that allows homeowners to feed excess electricity back into the grid, and in return, they receive credits or compensation for the surplus energy. This is particularly beneficial when sunlight is abundant, and energy production exceeds demand. When sunlight is insufficient, electricity can be drawn from the grid as usual. This interaction with the grid enhances the overall efficiency and economic viability of solar panel installations.
