How do solar panels actually work?
If you have solar panels, or are thinking about getting them, this blog is a guide to help you understand a little bit more about this incredible renewable technology.
Here’s our bitesize guide to better understand all things solar.
Simply put, solar panels absorb energy from the sun and convert it into Direct Current (DC) electricity. An inverter then converts this to Alternating Current (AC) electricity - which is what is used in most homes. This electricity then flows through your home, powering electronic appliances and devices. It can even be set up to heat your hot water or charge your electric vehicle. Any unused electricity produced by the solar panels is fed back to the electric grid, unless you have battery storage to save it for a rainy day.
But how do solar panels generate electricity?
A photovoltaic cell absorbs incoming energy in the form of sunlight. Photons (the particles of light energy) pass through a semiconductor, such as silicon, knocking off electrons. The electrons begin to flow through the electrical circuit, generating an electrical current. Wiring captures the electrical current and combines it with power from other solar cells. This electricity is then used to power your home.
And the benefits are huge.
Renewable energy.
Solar energy is accessible for as long as we have the sun, which scientists reckon will be at least five billion years.*
Cost saving.
A 12 panel solar system and battery could see savings of up to £904 a year
^^ on your home's electricity bill.
Set up and sit back.
Solar panels are generally low maintenance. For optimal performance, they just need cleaning a couple times a year - and the rain often does it for you.
