10 Best 100 Watt Solar Panels Reviews In 2021 – [A Buyer’s Guide]

Solar Panels, as the name predicts, is a technology that transforms solar energy into electricity. Initially in 1954, there were solar cells made from silicon.

A panel is an advanced technology made up of those solar cells. Since solar panels consume light energy therefore this technology is also known as Photovoltaics i.e. ‘Light-Electricity’.

Working on a Solar Panel:

Solar panels always fit in direct sun exposure. When sunlight hits the solar cells, they convert this light energy into DC electricity, then it is converted into AC electricity by an inverter.

This AC electricity is used in houses, offices et cetera.

Categories of Solar Panels:

Based on manufacturing, shape, working, price, and installation methods, Solar

Panels are categorized into three types:

  1. Monocrystalline Solar Panel
  2. Polycrystalline Solar Panel
  3. Thin-film Solar Panel

A Monocrystalline solar panel is highly efficient and cost.

While that of Polycrystalline solar panel is less efficient than monocrystalline and is less costly. And a Thin-film solar panel is the lowest in terms of efficiency and cost.
