The biggest benefit of solar panels is that it is both clean and a renewable source of energy. Because of global climatic changes, it is becoming imperative that we do whatever we can to decrease the pressure on the atmosphere due to the discharge of greenhouse gases. The solar panels that we recommend possess no moving parts and require a minimum amount of maintenance. They are ruggedly built and last for a long duration of time if maintained properly. Another benefit of the solar panels we recommend is that you will pay for the initial installation but will be provided with power for more than 30 years free of cost!

When choosing solar modules, one of the basic decisions to make is about technology. Do you prefer Poly-crystalline or Mono-crystalline modules?
Monocrystalline Silicon Solar Cells
Solar cells made of monocrystalline silicon (mono-Si), also called single-crystalline silicon (single-crystal-Si), are quite easily recognizable by an external even coloring and uniform look, indicating high-purity silicon, as you can see on the picture below:
Polycrystalline Silicon Solar Cells
The first solar panels based on polycrystalline silicon, which also is known as polysilicon (p-Si) and multi-crystalline silicon (mc-Si), were introduced to the market in 1981. Unlike monocrystalline-based solar panels, polycrystalline solar panels do not require the Czochralski process. Raw silicon is melted and poured into a square mold, which is cooled and cut into perfectly square wafers.
Solar panels are now being designed to take advantage of a broader spectrum of the sun’s rays. The panels are built with multiple layers of cells. Solar energy is stored in each layer. To maximize efficiency, each layer of cells is constructed of a different substance. Each substance is particularly receptive to the type of solar energy that layer stores. Referred to as multifunction devices, these solar panels use amorphous silicon combined with gallium arsenide.
Solar energy that is found in the shorter wavelengths has the greatest levels of natural energy. These are absorbed in the top layers. There, an electrical charge is created. When solar energy from different wavelengths in the spectrum reach the top layer, they pass through to the lower layers in the panel. It is in these lower layers that they are absorbed and an electrical charge is produced. While the theory behind these multifunction devices seems sound, research is still being conducted.
Choosing the right type of solar panel
Each type of panel, whether it uses a crystalline or amorphous silicon, has inherent benefits and drawbacks. Monocrystalline panels are incredibly efficient but costly. Polycrystalline panels are less expensive but less efficient. Amorphous panels are very inexpensive to purchase and install, but yield much less energy efficiency and thus, lower long-term savings. To select the right type of solar panels for your home, you will need to consider your budget and energy requirements. In the end, you’ll need to think of the long-term savings balanced by your upfront investment.
