Basically, there are three basic types of solar cells: amorphous – or thin-film – solar cells, monocrystalline and polycrystalline cells. Their efficiency and production costs are, however, very different. Below you can find types of solar cells:
Amorphous solar cells
This type of solar cells is the most popular since its production costs are low. The efficiency of amorphous solar panels is between 6 to 8 % that is not as high as the other solar cells. Due to its low efficiency it requires much higher surface to cover the same efficiency. The amorphous solar cell utilizes better the scattered light than the direct sunshine.
Monocrystalline solar cells
Nowadays it is the best of existing solar cells in efficiency with its 16 to 18 % performance. The monocrystalline solar cell can make better utilization of the direct sunshine.
Polycrystalline solar cells
Its efficiency is between 14 to 15 %. Thanks to the advanced technologies its efficiency is slightly lower than that of the monocrystalline solar cell. The polycrystalline solar cells can make better utilization of the scattered solar energy.
Thanks to their output signal shape and triggering current signaling abilities they are applicable in wide range of utilization. Due to their excellent parameters (such as high efficiency, low idle power consumption, wide range of protection functions, low mass, etc.) they are rightly popular and appreciated. With the inverter it is possible to produce 230V - 50Hz voltage from lower voltage source (12V, 24V, 36V). Such as i.e. batteries that can be fed by solar systems and then can be increased to grid voltage level by inverters.
