Profile: Yenny Industry Co., Ltd specializes in developing and applying small power vertical wind turbines (VAWT) & solar photovoltaic systems. Vertical axis wind turbine has a power of 300 w-10 kw. The blades of the turbine are in C type design which make it easy to start up. The wind resistance is smaller and our turbine can catch much more wind power when start up and the cut in wind speed is lower. Power beyond 2kw have in-grid controller and inverter for choose. Our solar panel includes mono solar module and poly solar module. Photovoltaic (PV) or solar cell is the basic building block of a PV or solar electric system. An individual PV cell is usually quite small, typically producing about 1 or 2 watts of power. To boost the power output of PV cells, we connect them together to form larger units called modules. Modules, in turn, can be connected to form even larger units called arrays, which can be interconnected to produce more power, and so on.
