Types of Solar Panels

Jun 24

Solar panels come in different types, including monocrystalline, thin-film, CdTe, and CIGS. Let's discuss the differences between these types. These panels produce energy from solar cells, which are made of silicon wafers. Monocrystalline panels contain a single silicon crystal, while polycrystalline solar panels are made of fragments of silicon crystals. To help you decide which type of solar panel is right for your needs, we've outlined the pros and cons of each.

Monocrystalline solar panels

The process of making monocrystalline solar panels is similar to the production of polycrystalline solar panels. Both panels are made from silicon, which is a chemical element found in the earth's crust. Silicon has a larger surface area than polycrystalline panels and, as a result, has a higher energy density. Monocrystalline solar panels contain approximately 60 to 72 solar cells. The number of cells can vary, but most residential installations use a 60-cell monocrystalline silicon panel.

Thin-film solar panels

The history of thin-film solar panels dates back to 1976 when Spear and LeComber first observed doping in amorphous silicon, and subsequently demonstrated their first thin-film solar cell. Although Amorphous Silicon (a-Si) has generated high expectations, it also has its own set of drawbacks, including weak bonds and low efficiency. To overcome these drawbacks, the PV industry has turned to a new approach: thin-film polycrystalline silicon on glass. This method is a combination of amorphous silicon, doping silicon and adding an antireflection coating to textured glass. The texture on the glass enhances the efficiency of the solar cell by approximately 3%, as it reduces the reflection of incident light from the glass onto the panel. The process requires an annealing step, in which the silicon film crystallizes, and

CdTe

In recent years, manufacturers of solar panels have been working to make CdTe panels. These panels have all-black designs, and use the full visible spectrum of light for photovoltaic conversion. They also outperform Si panels in hot and cloudy climates. Read on to learn more about CdTe solar panels. This is an important technology for solar panel makers. You can save money on your electricity bills by choosing CdTe solar panels for your home or business.

CIGS

A CIGS solar cell is a thin film module that is comprised of copper, indium, and gallium. The CIGS technology is increasingly popular in solar panel applications, including utility-scale installations, PV rooftops, and flexible thin-film panels. In this article, we will describe the basic structure of a CIGS solar cell and discuss its benefits. To understand the structure of a CIGS solar cell, let's examine its different components.

Amorphous silicon

Amorphous silicon solar panels are gaining ground as more homeowners are deciding that they want to reduce their energy bills. In addition to reducing their carbon footprint, amorphous silicon panels have several advantages. Amorphous silicon panels are easier to manufacture and tend to be less expensive than crystalline silicon. However, there are still some disadvantages, which we'll discuss below. Amorphous silicon is not yet as efficient as crystalline silicon.
