DETERMINING TIMING FOR CLEANING ELECTRICITY GENERATING SOLAR PANELS

摘要

A system for detecting an optimal timing for cleaning duty solar panels is provided herein. The system includes: a simulation sensor and a reference sensor which include photovoltaic cells identical to the photovoltaic cells of the duty solar panels, wherein the simulation sensor is configured to generate a simulation electrical signal which simulates electricity signal generated by the duty solar panels; and wherein the reference sensor is configured to generate a reference electrical signal which simulates electricity signal generated by the duty solar panels in a clean condition; and protection means configured to selectively expose the reference sensor for a specified period of time, wherein the system is configured to compare the simulation signal and the reference signal when the reference sensor is uncovered and provide an indication that the duty solar panels should be cleaned if a difference between the simulation and the reference signals exceeds a predefined level.
