Most solar cells are made of polycrystalline or monocrystalline silicon. Polycrystalline cells are most common as the relation of price and efficiency is quite good. Thin film solar cells are more expensive, but have some significant advantages to others.
Professional maintenance and installation of solar panels are important for good performance. Your solar installer will supply the equipment that is necessary for the scaffolding. Once the system is installed, only little ongoing maintenance is required.
Installing solar panels is a great way to invest in the health of our environment. The cost to install a solar panel may seem intimidating, but in reality the installation cost of a solar panel system is now more affordable than ever before.
