How Solar Energy Works

Photovoltaic (PV) Cells and Solar Panels

The heart of a solar system is the photovoltaic (PV) cells. These cells are made up of semiconductor materials, typically silicon, which has the unique ability to convert sunlight directly into electricity through the photovoltaic effect. When sunlight strikes the PV cells, the photons in the light excite the electrons within the cells, generating an electric current. Multiple PV cells are connected together to form solar panels. These panels are then mounted on rooftops or ground-mounted in a location that receives ample sunlight throughout the day. The number and configuration of solar panels depend on the energy requirements of the property.

Inverter and Net Metering

The electricity generated by solar panels is in the form of direct current (DC), which is different from the alternating current (AC) used in most homes and businesses. To make the electricity compatible with your existing electrical system, an inverter is used. The inverter converts the DC electricity produced by the solar panels into AC electricity that can be used to power your appliances, lights, and other electrical devices. In a grid-connected solar system, excess electricity generated by the solar panels can be fed back into the utility grid. This process is known as net metering. A bi-directional meter measures the electricity flow, allowing you to receive credits for the excess electricity you generate. During periods when your solar system doesn't produce enough electricity, you can draw power from the grid, utilizing the credits you earned earlier. Net metering ensures that you have a constant and reliable source of electricity.

Battery Storage, Monitoring, and Control Systems

To further enhance your solar system, you can incorporate battery storage. Batteries store excess electricity generated during the day for later use, such as in the evening or in the event of a power outage. This allows you to maximize self-consumption of the energy you generate and further reduce reliance on the grid. Battery storage systems are particularly beneficial for achieving energy independence and providing backup power. To monitor the performance of your solar system, you can utilize advanced monitoring and control systems. These systems provide real-time data on electricity production, consumption, and overall system performance. You can access this information through mobile applications or web portals, empowering you to track energy generation, monitor savings, and optimize energy usage.
