LG Solar Panels vs. SunPower Solar Panels- Which Is Better?

In recent times global warming has been the headline of many news as well as rising pollution is a matter of great concern for ourselves and for our upcoming generation. People are changing their focus from polluting sources of energy to sustainable and non-polluting sources of energy which can fulfill their needs without leaving a fatal fingerprint on livelihood and not disturbing the ecosystem. Nowadays, solar is gaining much more popularity than ever before and is capable of being an alternative source of energy and replacing polluting sources of energy. 

If you are looking to buy solar panels, you can consider LG solar panels and SunPower solar panels as these two brands are the most popular and trustable brands. In this article, we are going to learn about LG solar panels, their features, SunPower Solar panels, their features, and LG vs SunPower solar panels. 

What is a solar panel?

In simple terms, a solar panel is a device that converts light energy(sunlight) into electrical energy. It is also known as a photovoltaic (PV) panel made up of a collection of solar cells that are made of semiconductor materials like silicon. A single solar panel is a group of solar cells that can provide a sustainable and reliable source of electrical energy thus reducing our dependence on polluting sources of energy.

How do solar panels work?

Solar panels work by converting sunlight into electricity through a process called the photovoltaic effect. When the light reaches the solar cell, it gets absorbed by the electrons in the silicon,  causing them to move and generate an electric current.  

Benefits of using solar panels

  • Renewable source of energy: Solar energy is a renewable source of energy. It means that it can be used again and again as it is an unlimited source of energy and not like coal and petrol which are limited in nature.
  • Cost-effective: Solar panels cost only at the time of installation and after that provide a sustainable source of energy for years and pay off justifying their value at the beginning
  • Low maintenance: Solar panels require very little maintenance as they have no moving parts. The only thing to be taken care of is that we must ensure that nothing settles over the panel as it can affect the energy output of the solar.
  • Environmentally friendly: Solar energy is a clean source of energy that does not produce any harmful substances that pollute the environment.
  • Energy independence: This quality of solar panels gives us the freedom to construct at any part of the planet as we don’t have to fear “will the electric current will reach here or not” before constructing our houses, hotels, etc.
