Solar cells are often connected and wrapped an electrical system as a module. This module will usually have. Glass front (facing the Sun). Let light through while it protects the semiconductor wafers from scratch and raengkrathop due to dust, rain, wind, blow came with the hail, etc, solar cells also have a serial connection on the pressure phopwok module together. Although the cell connection in parallel to give higher currents, but there are very important issues that occur. For example, the impact can make the row from the shadow (of multiple cells per serial) weak close the parallel decrease (less bright), causing a significant loss of power, and also destroyed a row of the weak. Due to the assumption that Dubai is back, too, that the cell shadow lighting partners. A string of serialized cell often managed independently and not be connected in parallel unless they are in parallel, even if the module can be connected between each other to create an array with. Maximum DC voltage and load generation by using independent MPPTs (maximum power point trackers) that will provide a better exit. In cases where there is no parallel shunt diodes can be used to reduce the energy loss due to shadows in the array to set the cell to a serial/parallel.In order to use the energy generated by the Sun in practice. Most often the input electric current electric grid using inverters (photovoltaic systems connected to the grid); In stand-alone systems, batteries are used to store energy that is not required. Solar panels can be used to provide power or charge portable devices.
