Maximum power point creator collocating solar power cells for skewed surface

Solar power is spreading all over the world due to energy policy. Increasing pollution and energy price force to improve solar energy rate in total energy. On the contrary, solar power has some drawbacks. Environmental conditions such as dust, shadow and heat directly affect the solar power cell capability. Especially shadow is one of the biggest problem may can cause broken the cell increasing internal heating of cell under load. Moreover, in case of the shadow position or angle any leg of solar power may collapse and other side of leg force the collapsed side to broke via reverse current flows. Generally, maximum power point tracking method is based on reducing power flows related to generated solar power and only could be adjusted current flows regarding instant cell capability. In this study, a hardware organization was created by microcontroller to obtain maximum power ability. Grouped all cells could be connected each other's. Created groups are paralleled to increase current capability.
