The improvement of photovoltaic module power is the first technical means that improves the generated energy, reduces the land area. In the early 2021, each large photovoltaic manufacturer pushes out more high-power components, and the maximum power can reach 670W. However, the high-power components are developed, and the matching technology is not perfect. The engineering practice application power is still mainly 450-530W. The application of the flat single-shaft support tracks the movement track of the sun, and the generated energy is obviously improved. The current tracking technology is relatively simple, and the timing design of a system is mainly used for tracking a track. The tracking technology cannot keep the optimal angle between the photovoltaic panel and the direct sun point, cannot solve the shielding problem, and cannot fully improve the power generation capacity. Therefore, we improve the above and propose a distributed photovoltaic measurement device which can be connected to a power grid.
