To keep it simple, let's break down what contributes to the total load of a PV system: Solar panels – Typically weigh between 10-15kg per square metre, depending on the make and model. Most high-strength solar panels are designed to support loads exceeding 5400 Pa, which is roughly equivalent to 540 kg per square meter. 5 square feet of panel area per module. Heavier, high-wattage or larger-format modules can approach 50 pounds, while some lightweight. . On average, a complete solar array adds about 2 to 4 pounds per square foot (psf) to the roof. For a standard 6kW system covering 400 square feet, this translates to an additional 800 to 1600 pounds distributed across the roof structure. A typical residential array will weigh well below the average roof's weight-bearing capacity.

Shielding effect: Dust particles act as a barrier, blocking and scattering incoming sunlight before it reaches the solar cells. . The presence of dust on solar panels can have a profound impact on their energy production capabilities. Studies have consistently shown that the accumulation of dust on panel surfaces directly translates to decreased power output. After examining the articles published in international scientific journals, many differences between the studies were found within the context of the PV. . The dust deposition on the surfaces is a complex phenomenon which depends on a large number of different environmental and technical factors, such as location, weather parameters, pollution, tilt angle and surface roughness.
