SAMBO Launches Innovative Self-Cleaning Nano Coating to Enhance Solar Panel Efficiency
Solar energy, as the largest renewable energy source globally, is developing rapidly. However, the accumulation of dirt on solar panels can severely impact their efficiency. Given the vast number of panels in photovoltaic power stations, regular cleaning is not only time-consuming but also labor-intensive. Therefore, the development of “self-cleaning” technology has become an ideal solution.
In response, scientists worldwide are actively conducting related research. Recently, Hong Kong startup SAMBO introduced a hydrophilic self-cleaning nano coating designed to mitigate potential material degradation and reduce cleaning costs for photovoltaic stations in both dry and humid environments.
Features of the Innovative Coating This transparent coating possesses self-maintaining, anti-fouling, and anti-static properties, initially designed to inhibit the growth of algae and lichens on solar panels. Algae growth, particularly in tropical regions, poses a significant challenge; if left unchecked, it could lead to a loss of up to 26% in solar module energy generation capacity.
According to data from the International Energy Agency’s Photovoltaic Power Systems Programme (IEA-PVPS), pollution of photovoltaic modules results in annual revenue losses exceeding $3.2 billion, and this figure is expected to reach between $6 billion and $10 billion in 2024.
Advantages of Self-Cleaning Technology In addition to preventing algae growth, the hydrophilic and anti-static properties of this coating effectively inhibit the adhesion of sand, dust, and other pollutants. Its self-cleaning feature means that rainwater can easily wash away surface contaminants. SAMBO explains, “Unlike waterproof coatings, the hydrophilic effect reduces the contact angle of water droplets, allowing water to penetrate beneath the contaminants for more effective dirt removal. Additionally, the anti-static properties enable larger particle pollutants like dust and sand to slide off easily.”
