Utility bills are overwhelming at times. This is especially true when your costs for heating and cooling in a city like Albuquerque, NM, are not consistent and hard to plan for.
So, you are considering installing solar panels to cut the utility cost. But there are many types of solar panels in the market, and so it can be hard to make a decision. There are many factors to consider when buying a solar system. But first, understand the components of solar panels and the main types.
Crystalline Silicon (c-Si)
Today, most solar photo-voltaic systems consist of silicon. In its many different forms, silicon and the different types of solar panels depend on the purity of silicon.
What Is Silicon Purity?
Silicon purity refers to how perfect the silicon molecules align themselves. Perfectly aligned silicon molecules enable the solar cell to convert solar energy into electricity efficiently. Crystalline silicon is the basis of the two common types of solar cells. These are mono-crystalline and poly-crystalline solar cells.
Mono-crystalline Silicon Solar Cells
Solar cells made of mono-crystalline silicon have a uniform and even color. This is proof of the high purity of the silicon. The solar cells consist of cylindrical silicon bars. The bars are further made into silicon wafers after cutting out four sides. It is these wafers that give mono-crystalline solar cells their unique look.
Poly-crystalline Silicon Solar Cells
Poly-crystalline solar cells have a rectangular shape after combining several square wafers. The solar panels do not need the Czochralski process, unlike the mono-crystalline counterparts. The manufacturing process involves melting raw silicon. After that, it is time to pour the substance into a square mold to create square wafers.
Apart from the type of solar panel, there are other factors to consider when choosing the right solar panel for your home. Hire solar panel experts to evaluate your particular situation. Other factors include location, budget, and heating and cooling needs. Only then can you determine the best solar panels system for your home.
