Traditionally, the original blueprint of buildings was used as a reference of measurement when carrying out planning and calculations for installing new photovoltaic stations. An alternative is for workers to manually scale the roofs and take measurements by hand. The process is long, tedious and pose a safety hazard to workers. These processes are often affected by inclement weather and equipment constraints. Ultimately, it reduces the accuracy of measurement data and efficiency of photovoltaic station installation.

Slight occlusions, burns and cracks cause solar panels to generate hotspots, affecting the electricity generation efficiency of the solar panels. These damages could lead to permanent damage of solar-powered battery cell components or even trigger a fire hazard. Traditional maintenance methods rely on human patrols, but given that photovoltaic stations usually span over large areas with great changes in altitude throughout the stations, this method is inefficient and can pose safety hazards. In addition, inspection results are based on the staff's experience in detecting damages, which commonly result in deviations of the reliability of inspection results.
