Generally, monocrystalline silicon solar PV is the best technology to deliver efficiency, as measured by wattage output related to the panel’s size. But this efficiency can come with costs. The best value is solar PV technology is polycrystalline silicon, offering efficiency levels close to monocrystalline panels, but at half the costs in some cases.
Polycrystalline solar is made by pouring molten silicon into a cast. However, because of this construction method, the crystal structure will form imperfectly, creating boundaries where the crystal formation breaks. This gives the polycrystalline silicon its distinctive, grainy appearance, as the gemstone type pattern highlights the boundaries in the crystal.
The technology with the lowest market share is thin-film, but while it has several disadvantages, it is a good option for projects with lesser power requirements but needs for light weight and portability. Thin-film technologies have produced a maximum efficiency of 20.3%, with the most common material amorphous silicon at 12.5%.
Solar energy is converted into electricity and fed into the public grid. Efficient, reliable, high power inverters form the heart of any PV system. In the development of PV inverters, Fronius has thought out new technologies, searched for innovative solutions, and has found completely new answers. The result: Highly functional mains-connected inverters, which interact optimally with all solar modules.
