    • Various embodiments herein include at least one of systems, methods, and software to facilitate automatic solar power surface-cleaning. Such embodiments include at least one automatic solar power surface-cleaning robot that uses no water or external power, continuously cleans the solar power surfaces and requires no maintenance or external power. The solar power surface-cleaning robot is easy to retrofit in an existing solar power generation plant. An automatic solar power surface-cleaner uses high-voltage AC electric fields to sweep particulates and debris as the robot traverses the surface to be cleaned. Photovoltaic solar cells supply the power for the robot. No external power is required. The robot clamps to the surface to be cleaned at the edges using motor driven rollers. Electronics inside the device generate high-voltage AC that is applied to conductors close to the surface to be cleaned.
    • 本文的各种实施例包括用于促进自动太阳能表面清洁的系统,方法和软件中的至少一个。 这样的实施例包括至少一个不使用水或外部电力的自动太阳能表面清洁机器人,连续地清洁太阳能发电表面,并且不需要维护或外部电力。 太阳能表面清洁机器人在现有的太阳能发电厂中易于改造。 自动太阳能表面清洁器使用高压交流电场来扫描微粒和碎屑,因为机器人穿过要清洁的表面。 光伏太阳能电池为机器人提供动力。 不需要外部电源。 机器人使用马达驱动的滚轮将其夹在边缘的待清洁表面上。 设备内部的电子产生高压AC,其被施加到靠近待清洁表面的导体。

    • Described herein is a low-voltage unidirectional bypass element connected across a solar cell and operable to allow current to flow when the operation of the solar cell is suspended. The bypass element includes a single field effect transistor connected between first and second terminals as a switch, and a detection circuit for detecting suspension of the solar cell's operation and activating the switch to bypass the solar cell in the event of its operation suspension. Diodes are connected in parallel with the normally-open switch and receive current, when the solar cell's operation is suspended, to trigger operation of the detection circuit. The detection circuit includes a charge pump, a timer circuit, a control generation unit and a switch control circuit. The switch control circuit generates a control signal to close the switch and to allow current to bypass the solar cell.
