Problems solved by technology

[0002] Solar cells must be connected in series, in parallel, and tightly packed into modules to be used as power sources. Photovoltaic modules are the core part of solar power generation systems. When solar cells work, they generate large operating currents. The inverter and power grid work in the frequency range of power frequency to hundreds of kilohertz, so static and alternating electromagnetic radiation will inevitably be generated, which will affect the operation of photovoltaic module equipment and human health
