No, there are a variety of panels. The two most commonly used are Monocrystalline silicon and Polycrystalline silicon panels. What separates the two is the purity of silicon used to manufacture the cells. Clear Solar uses Monocrystalline, all-black, 60 cell panels.
Monocrystalline solar panels have the highest efficiency rate; they are space efficient and they last the longest. The panels are made from the highest grade silicon, which allows an efficiency rate ranging from 15-20%. These solar panels yield the highest power outputs while acquiring the least amount of space. Clear Solar offers a 20-year linear power warranty on Monocrystalline solar panels.
Polycrystalline solar panels' efficiency ranges only from 13-16% and are less space efficient. Due to the lower silicon purity, polycrystalline solar panels have a lower efficiency than monocrystalline solar panels. Polycrystalline solar panels are less space-efficient due to a larger surface that must be covered to output the same electoral power as a monocrystalline solar panel.
