Polycrystalline silicon panels are becoming very popular these days. However, they are not as efficient as monocrystalline due to the quality of silicon used. The average cost of polycrystalline solar cells ranges between $200-$500. They also do not perform well in warm temperatures. This is why they are cheaper than monocrystalline.
Amorphous silicon cells, also known as thin-film, use the least amount of silicon. Due to this, it is not very efficient. However, they are one of the cheapest options and degrade faster than other panels. The cost ranges from $175-300 USD per panel. These types of panels usually require more space and are not recommended for smaller homes. They need twice as much space as required by mono or polycrystalline solar cells.
Some other specifications
Solar panels have different specifications based on which their performance depends. These specifications indicate their technical attributes. It can help you in the long run if you take note of them when making a choice. Voltage and coefficient of temperature should be one of your major concerns. A good temperature coefficient indicates better performance in high temperatures. For voltage, 100V DC minimum should be considered for safety. For the factor of power tolerance, it is advised to look for 0% negative power tolerance in panels.
Quality
The quality of solar panels should be taken into account when you are buying them. This is something that makes things reliable or poor. Various types of manufacturing companies produce multiple solar panels, varying based on quality, price, and efficiency. The quality of the material and the process of production decide the reliability of solar panels. Some companies invest a lot of time and money into research and development from start to the end to ensure quality. However, other companies do not manufacture them but only assemble them rather than invest time and money. Hence when choosing the supplier, it is advised to take a look at all these factors. Since it will be a huge financial investment, it is wise to check the history of the company and look at its review.
Hence, now you have the factors that you can compare to get the solar panel systems that best suits your needs. You should take a deep look at these parameters and perform complete research. Before being deceived by the hot offers or sales, you should compare them and find the original and genuine one.
