General technical requirements for photovoltaic module cleaning robots

1 Scope

China's national general specification for photovoltaic module cleaning robots. Soiling is the largest avoidable loss in a solar plant: dust on the glass costs a few per cent of output in a temperate climate and can cost twenty or more in an arid one, and China's largest arrays are in exactly the desert regions where it is worst. Cleaning them manually is impractical at gigawatt scale and washing them consumes water that is not available there. A cleaning robot traverses the module rows with a rotating brush, dry, on a schedule, and either lives permanently on a row or is moved between them. What the specification has to address is what the machine must not do as much as what it must: the glass has an anti-reflective coating a few hundred nanometres thick that a harsh brush will abrade, and a robot that damages the coating costs more output than the soiling it removed.

This document specifies the product classification, technical requirements, inspection rules and marking, packaging, transportation, storage requirements of photovoltaic module cleaning robots. The corresponding test method is described. This document applies to the manufacture, testing and use of photovoltaic module cleaning robots.
