Traditional Solar Monitoring System VS Pixel View Safety Pixel View can not only monitor the voltage and current of each string, but also send out alarm notifications when the system detects any underperformance, failure, or malfunction, which significantly reduces the danger of electricity leakage and electric fire due to short circuit incidents. Monitoring The robust software system can immediately diagnose the cause of any unusual electricity event to minimize the traditional manual inspection costs by increasing the O&M efficiency of power plants maintenance. Operation & Maintenance Pixel View features floor plan functionality that can clearly locate and display the abnormal solar modules to accelerate the intelligent diagnostic analysis. Technicians and maintenance personnel only need to repair or clean a particular region of modules to catch the golden 30-minute system repair time. Immediate Judgement for Shading Effects The output of cells declines when the panel is shaded by a tree branch, snow, dust, or building shadow. Since solar cells are connected in series, the shaded cell will cause a decrease in current output on a particular region of solar panels, which directly influence the current output of the entire series and drop the serial productivity. Pixel View can help users to determine when shading effect occurs and react promptly, effectively preventing permanent overheat damages to the system. 9
