How Do Solar Panels Work?

Solar Panels On Roof Of House

Solar panels work by converting energy from the sun into power. Solar PV (photovoltaic) installation sees the application of solar panels to a domestic, commercial, or industrial setting. Read on to find out more about how they work, how they’re installed, and how they can benefit you.

Integrated PV Cells

When sunlight shines onto a solar panel, the energy is absorbed by the PV cells in the panel. PV cells are made from layers of a semi-conducting material, often silicone. In turn, the energy absorbed from the sun then creates electrical charges that move in response to an internal electrical field within the cell. This causes electricity to flow.

Storing Electricity

Solar panels have the ability to convert sunlight into DC (direct current) electricity. This then passes through a charge controller and is stored in the battery. The controller also regulates the flow of electricity from the panels, ensuring the battery doesn’t become over or undercharged. Typically, a standard solar battery will hold charge for 1-5 days.

Moreover, any excess electricity from the solar panels can be sent back into the grid. Your utility company may even provide you with credit for energy that you send back to it. This is known as net metering.

Solar Panel Installation

Solar panels are usually placed at an angle, facing towards the sun. This is in order to maximise energy production. Installers fix the panels to the ground or roof by attaching mounting rails and then attaching the panels to these rails.

Once the panels are absorbing and storing solar energy, the current passes through an inverter to turn it into AC (alternating current) electricity. This is the kind of current you need for household appliances. The inverter is connected to your battery and to your fuse box, which brings the connection into your home.

Benefits Of Solar Panels

There are several benefits of solar panels. As technology is advancing, they are becoming increasingly affordable to install. Because they don’t produce air pollution or greenhouse gasses, they’re also a more environmentally friendly alternative to other energy sources.

Additionally, they help to reduce your energy bills as you’re less likely to rely on energy coming directly from the energy grid. Furthermore, if the grid goes down, you’re able to keep your electricity flowing as you can rely on solar energy stored in your battery.
