Our modules are customised with a single module size of only 766 mm and can therefore be adapted to the needs of balconies of different sizes for solar power systems. For small balconies, four 200 W modules can be installed on a balcony length of 3.2 metres to achieve 800 W of power generation. In addition, the optimised design of the system connection allows individual connection so that users can freely combine 1-6 modules according to their needs to maximise their power consumption.
