When shopping for a solar panel brand, the issues at the forefront of people?s minds are usually topics such as the efficiency and wattage of a solar energy system. An often overlooked issue is glass and the type of glass used on a solar panel really does matter. When selecting either a monocrystalline, polycrystalline or amorphous solar panel, be sure to check out the type of glass being used. Look for panels that utilize tempered glass. This should be clearly stated in the panel specifications. Tempered glass, also known as safety glass or toughened glass, is anything up to six times the strength of normal plate glass. Using poly is cheaper than using glass but is less efficient and deteriorates over time. Tempered glass does not. You get what you pay for.
