How Do Solar Panels Work?

Over the last 10 years, the rapid growth of the solar industry has demanded attention. Large agencies such as Tesla and the European Union are embracing solar as the wave of the future.From solar panels on rooftops to commercial solar street lights, the solar industry demands attention.

With all this talk about solar, have you ever wondered how a solar panel actually worked? Here’s a little introduction on what solar panels are and how they work.

What are Solar Panels Made Of?

Solar panels are one of the main components of a solar outdoor lighting system. They comprise multiple small grouped units called photovoltaic (PV) cells. These cells are made of two layers of semiconductor material typically comprised of silicon crystals.

Because silicon is a poor conductor of electricity, the bottom layer of photovoltaic cells is doped with boron, which facilitates a positive charge (P). On the other hand, the top layer is doped with phosphorus, adding electrons with a negative charge (N). Electron movement between the two layers with opposite charges produces an electric field.

Most PV systems are based on individual square cells that produce very little power, which is why they are linked together as panels or modules. These solar panels can be used individually or wired together into larger solar arrays to produce the desired electrical output.

How Do Solar Panels Work?

PV cells convert sunlight into electricity. When particles of light called photons hit the surface of a solar cell, they knock electrons loose from their atoms. When positive and negative charges are separated, an electric field occurs.

As electrons flow through an electrical circuit from one layer to another, they generate a flow of electricity. After the panels convert the energy to direct current (DC) electricity, an inverter converts it into alternating current (AC) electricity.

Alternating current is the type of electricity that consumers use when they plug their appliances into a wall socket. Only after it is converted to AC, electricity can be delivered to a business or a residence.

Solar panels and Outdoor Lighting

With modern technology, large corporations and municipalities are embracing solar and are investing in this growing infrastructure. Photovoltaic cells require no maintenance, produce no greenhouse gas emissions, and are environmentally friendly. Solar panels provide enough electricity both on sunny and cloudy days, and charge the batteries that can later power your residential or commercial solar lights during the night.
