Innovations in solar technology, such as bifacial panels and solar tracking systems, continue to enhance the efficiency and output of solar installations.

How Solar Panels Work

Solar panels, also known as photovoltaic (PV) panels, convert sunlight into electricity through the photovoltaic effect. Each panel consists of numerous solar cells made from semiconductor materials, typically silicon. When sunlight hits these cells, it excites electrons, creating an electric current.

Photovoltaic Cells

Photovoltaic cells are the building blocks of solar panels. These cells are made from silicon wafers, which are treated to create an electric field. When photons from sunlight strike the surface of a PV cell, they knock electrons loose from their atoms, generating a flow of electricity.

Energy Conversion Process

The electricity generated by solar panels is direct current (DC), which needs to be converted into alternating current (AC) for most household and commercial uses. This conversion is done by an inverter, which ensures the electricity produced by the solar panels can be used by standard electrical appliances and fed into the grid.

Benefits of Solar Energy

Solar energy offers numerous benefits, making it an attractive option for powering electric vehicles and other applications.

Environmental Impact

One of the most significant advantages of solar energy is its minimal environmental impact. Unlike fossil fuels, solar power generation produces no greenhouse gas emissions, reducing the carbon footprint and helping combat climate change.
