Solar batteries mainly consist of silicon photovoltaic cells, which are essentially large semiconductor diodes. The most popular solar batteries on the market are manufactured using monocrystalline or polycrystalline silicon technology.
- Monocrystalline silicon production technology was developed first. Monocrystalline solar batteries are relatively more expensive, as their production requires the use of very pure monocrystalline silicon. The production process is technologically complex, but monocrystalline solar batteries have a very high efficiency coefficient.
- Polycrystalline silicon solar batteries have lower production costs, but their efficiency coefficient is a couple of percent lower than that of monocrystalline solar batteries.
The output of a single solar battery panel ranges from 150W to 300W. Depending on the output required, systems with multiple batteries are formed – usually systems of at least several kW (1kW (kilowatt) = 1000W (watts)).
Solar batteries are placed on building roofs, facades or on the ground. An inverter is installed inside the building, which converts the direct current generated by the solar batteries into alternating current for self-consumption and for feeding surplus energy into the shared electricity grid.
The generated energy can not only be fed into the shared grid, but can also be stored in special batteries during daylight hours, for use during the dark hours of the day or during power supply interruptions from the grid.
COMMODUS offers solar batteries, system components, as well as ready-made solar battery system packages. Ready-made system packages help you better understand what such systems consist of, what the total installation costs are, and allow you to purchase them more cheaply.
