Polycrystalline, which is also called poly or multicrystalline, has been used since 1981. Polycrystalline solar panels are easily identified by their solar cells that have a textured look resembling a granite countertop or shattered glass.
Polycrystalline cells are composed of multiple silicon crystals, which is a cheaper way to manufacture solar modules. Put simply, these cells are easier for a factory to produce, so they are less expensive. Polycrystalline cells are made by several methods, but most commonly with a cast of molten silicon. When these cells are being created, they cool faster, creating smaller crystals. Just remember that “poly” means “many,” so it has many crystals.
Polycrystalline solar panels are one of the cheapest systems available. Polycrystalline solar panels are made up of silicon crystals that convert the energy produced by sunlight to electricity. While Polycrystalline is one of the oldest solar panel technologies, it has been tested and refined, making it one of the cheapest and therefore ideal for a variety of homes and businesses. When properly installed, these panels augment electricity from local power company grids, reducing monthly consumption and costs.
Regardless if you are looking for a rooftop array to add to your home’s electrical supply or a series of arrays to augment power for a factory operation, Global Efficient Energy can meet your needs. Our installation teams and technicians will set up your new photovoltaic panels and construct a system to deliver power directly to your breaker box and into your home or business for use. With this method, captured solar power is used before electricity from your power company; reducing your monthly energy bill.
