Solar Generator 101: What is a Solar Generator and How Does it Work

The immeasurable advancements in renewable energy technology led to the creation of solar generators, giving people a more reliable alternative to fuel-powered generators. Solar generators provide a more sustainable and cleaner source of energy for different applications.

If you’re considering making the switch to solar generated power, but don’t know where to begin, in this comprehensive article, we would be delving into all there is to know about solar generators.

A solar generator or a solar power station is a self-contained unit that can transform sunlight into electricity. The generator does this through what is known as the PV (photovoltaic) effect. Solar generators are a reliable and renewable option for generating power, and they are eco-friendly because they harness the energy produced by the sun.

There are many different types and sizes of solar generators, and they all provide solutions to a wide range of energy needs. Whether it’s a small portable unit or large-scale stationary installations, they all serve the same purpose.

To understand how a solar generator works to produce electricity, you must first understand its components. Let’s dive into it.

Solar Panels: Solar panels or PV modules are the heart of every solar generator because they are in charge of capturing sunlight and converting it into DC (Direct Current) electricity for use.

Battery: Solar generators are built with a battery that stores the converted direct current electricity for future use. The battery ensures that the power supply is steady even when there is no sunlight or nighttime comes.

Charge Controller: The charge controller acts as an intermediary to regulate the flow of electricity between the battery and the solar panels. This prevents overcharging of the battery and possible damage while promoting the durability of the generator.

Inverter: The inverter is in charge of converting the stored DC (direct current) electricity to AC (alternating current) electricity so that it can be suitable for regular use. AC electricity is the standard electric current compatible with household devices and appliances.

DC Loads: Some devices can run on DC power directly without having any issues, so some solar-powered generators make provision for this by adding DC outlets. This allows you to connect your devices that DC electricity can power to the solar generator directly, canceling the need for a DC to AC electricity conversion.

Solar power generators are not too complicated in their function, but they work based on an established scientific effect known as the photovoltaic effect. When sunlight hits the solar panels, the photovoltaic cells in the panels absorb the light, to release and create an electric current.

The charge controller helps optimize the current flow into the battery and allows it to store any excess electricity produced when the sun is still out. The inverter converts the stored DC electricity into AC electricity, making it suitable for household use.

Solar generators offer a ton of benefits that have made them a necessity in our day. With more environmentally conscious people rising every day, and the need for a clean source of energy, solar generators have become the next best option. Here’s why you should use a solar generator:
