Monocrystalline solar panel cells tend to achieve higher levels of efficiency because they are made of more pure silicon. You will notice a uniformity to their coloring. Their cylindrical shape also helps these cells achieve higher efficiency. When choosing between a monocrystalline and polycrystalline solar panel system, it will be important to find your solar sun number score. This will allow you to find out how much potential your system will have with your location and amount of sunlight it receives.
