Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many, smaller units called photovoltaic cells. ... To work, photovoltaic cells need to establish an electric field.

What do solar panels do for your house?

Solar panels work on your home by converting photons from the sunlight into direct current, which then flows into your inverter. Afterward, your inverter translates the direct current into alternating current and sends the AC to your electric box to power your home.

Do solar panels really help?

Solar panels generate their own power and can therefore greatly offset your monthly electricity bill, if not eliminate it. The higher your bill, the more likely you'll benefit from switching. But you should note that electricity rates and usage — the main charges on your statement — are volatile.
