How Do PV Panel Batteries Work?
PV panel batteries work by storing excess energy generated by solar panels during the day for later use when the sun isn’t shining. When sunlight hits the solar panels, it generates direct current (DC) electricity. This electricity is then sent to an inverter that converts it into alternating current (AC) electricity, which can be used to power your home.
The excess energy produced but not immediately consumed is stored in the PV panel battery. These batteries are made up of multiple cells that store and release energy as needed. They utilize a chemical reaction between different materials inside them to store electrical energy.
When you need electricity at night or on cloudy days when there’s less sunlight available, the stored energy in the battery is discharged back as DC power through an inverter for use throughout your home. This continuous cycle of charging and discharging allows you to have a reliable source of clean energy even when the sun isn’t shining brightly.
