Comprehensive Guide to Selecting the Best Solar Panels for Rooftop

Investing in solar panels and solar energy projects is one sustainable way to grow your finances. Investing in such projects allows you to serve a dual purpose. To ensure your investment has good turnovers and reflects positively on your portfolio, know the best solar panels for rooftops so they give you the best value for money. This allows you to grow your wealth but at the same time you ensure that “green energy” becomes more accessible. 

3 Types of Rooftop Solar Panels

1. Monocrystalline

Our first kind of solar panels are the most common ones that you see in rooftop installations today. Monocrystalline silicon solar cells go through a special production method. In simple terms, a small silicon crystal goes into hot melted silicon. This creates a big crystal, called an ingot, which undergoes thin slicing to become solar panels. 

2. Polycrystalline

Polycrystalline panels are a budget-friendly option for people who want to use solar energy at home. They also have silicone cells, but they cool differently, forming multiple crystals instead of just one. The ones that are applicable for houses usually have 60 solar cells.

3. Thin Film 

Thin film solar cells are not as efficient but are commonly used in big solar projects for industries. They are amongst some of the best solar panels for rooftop. Thin films effectively convert sunlight into electricity onto a solid surface like glass. There are “special” substances in the film that do so. 

Some of them are amorphous silicon (a-Si), copper indium gallium selenide (CIGS), and cadmium telluride (CdTe). While making them, the substance becomes a thin and light sheet, and sometimes it can even be flexible.

Most of the solar panels in the market can fall under one of these categories. Therefore, let’s take a look at the best solar panels for rooftops.
