Understanding Solar Generators
What is a Solar Generator
A solar generator is a device that captures and converts solar energy into usable electricity. It consists of three main components: solar panels, a battery, and an inverter. The solar panels collect energy from the sun’s rays and convert it into DC (direct current) electricity. The battery stores the excess energy generated during the day for later use, and the inverter converts the DC electricity into AC (alternating current) electricity that can power household appliances and devices.
How Solar Generators Work
Solar generators harness the power of the sun to generate electricity. The solar panels, usually installed on the roof or in a sunny area, absorb sunlight and convert it into DC electricity. The DC electricity is then sent to the battery, where it is stored for later use. When electricity is needed, the inverter converts the DC electricity from the battery into AC electricity, which can be used to power various household appliances and devices.
