Polycrystalline panels, as well as monocrystalline, are made of silicon cells. But unlike monocrystalline, polycrystalline panels, otherwise known as multi -crystalline, are made up of cells, which are a combination of multiple small silicon crystals. This is the reason, why their surface is not homogeneous, thus, they are slightly less efficient and simultaneously, less expensive. Thanks to those characteristics of polycrystalline panels, they are commonly used in residential buildings and in large solar power plants.
The most commonly used material for the production of photovoltaic cells is silicon. It has the most efficient processing of solar radiation (beside gallium arsenide, which is only used in space due to the high cost). Monocrystalline panels are composed of individual cells that are formed of a homogeneous silicon crystal with systematic internal structure. They are formed by cutting the silicon block of appropriate size, for layers thick of about 0.3 mm. Panel produced this way has the highest level of efficiency and service life.
The inverter is an essential component of photovoltaic systems, which is used to convert direct current to alternating current. Appropriately selected device ensures safe and reliable operation of the system. Solar panels and inverters work in the less predictable conditions. Given the high cost of panels and associated electronics, it is therefore important, to use additional safeguards to protect the system against possible defects. Especially, the overvoltage, overload and temperature protection should be ensured.
Mounting system allows for a secure and stable installation of photovoltaic panels. Depending on the type of photovoltaic system there are different mounting systems. This is primarily determined by the conditions of buildings, such as: mounting on the roof or on a flat surface. The design may include, among others, supporting structures, roof brackets, mounting rails, flexible tubes. Well done mounting structure is designed to provide adequate slope of the photovoltaic panel and its safe operation.
The principle of the construction of thin film panels is different from the mono and polycrystalline panels. It involves the deposition of thin layers of silicon (about 2 microns) on the surface of another material, such as glass. It’s impossible to isoyearse the individual cells. It is the most economical way of producing
Accessories and cables are an essential element constituting the effectiveness, efficiency and safety of operation of the photovoltaic system. The main feature of these elements must be their perfect adaptation to other elements of the system and the highest quality of their workmanship.
