Background
Along with the continuous reduction of the component cost, the advantages of the intelligent photovoltaic component are increasingly highlighted, the development trend of the photovoltaic component is formed, and the intelligent photovoltaic component is also a great direction for the transformation and upgrading of Chinese photovoltaic component manufacturing enterprises. The rapid increase in 2018, SolarEdge, a global leader in the field of "power optimizers", also demonstrates this. According to statistics of IMS Research 2019, the market share of Solar Edge is about 85%. Enterprises such as Chinese photovoltaic module manufacturers, namely Australian, China and south photovoltaic, Saiying, Yihui and the like, have adopted a SolarEdge's power optimizer and have won the market in a differentiation manner in intense competition.

Compared with the traditional photovoltaic assembly, the intelligent photovoltaic assembly integrates a power electronic conversion device, such as a micro inverter or a power optimizer, and has the function of improving the overall power generation efficiency of a photovoltaic power station. In application, a plurality of photovoltaic modules are generally connected in series. If one of the blocks is blocked by the shadow, the output power of the block is reduced, the outputs of other components are also affected, and the power output of the whole string is greatly reduced. This is the so-called "series effect" or "domino effect" in photovoltaic power plants. The micro-inverter or the power optimizer can control the power conversion of the monolithic component, thereby eliminating the influence of the series effect. Meanwhile, the MPPT function of the component layer can convert the power generation capacity of the component to the maximum extent.
The photovoltaic module is a device for converting light energy into electric energy by using a photovoltaic effect. Because the output voltage of the single solar cell is low, and the electrodes of the unpackaged cells are easy to fall off due to the influence of the environment, a certain number of single cells are sealed into a solar cell module in a series-parallel connection mode to prevent the electrodes and interconnection lines of the cells from being corroded, and the cells are prevented from being cracked due to the packing, so that the outdoor installation is facilitated, the service life and the reliability of the solar cell module are determined by the quality of the packing quality, and the solar cell module is composed of a high-efficiency crystalline silicon solar cell, ultra-white cloth grain toughened glass, EVA (ethylene vinyl acetate), a transparent TPT (thermoplastic vulcanizate) back plate and an aluminum alloy frame. Has the characteristics of long service life, strong mechanical pressure resistance and external force, and the like. The conventional solar cell modules have the following structural forms, namely a glass shell type structure, a bottom box type module, a flat plate type module and an all-glue sealing module without a cover plate, and a wireless sensor generally uses a photovoltaic module for supplying power, but various solar modules on the market still have various problems.
