Solar powered street lamps installed outdoors are inevitably affected by natural factors, such as strong winds and heavy rain. Whether purchasing or installing, windproof and waterproof designs are often considered. However, many people overlook the impact of dust on solar powered street lamps. So, what exactly does dust do to solar powered street lamps?
Tianxiang self-cleaning solar street lights use high-quality solar panels and comes with a brush for regular cleaning, removing dust, bird droppings, and other debris. Whether it’s a rural road or an ecological trail in a scenic area, this self-cleaning solar street light is suitable, providing long-lasting, stable, and green lighting.
1. Obstruction
The most obvious obstacle is obstruction. solar powered street lamps operate primarily by absorbing light energy from solar panels and converting it into electricity. Dust on the panels can reduce light transmittance and alter the angle of light incidence. Regardless of the type, light will be unevenly distributed within the glass cover, unsurprisingly affecting the solar panel’s absorption of light and, consequently, its power generation efficiency. Data indicates that dusty panels have output power at least 5% lower than clean panels, and this effect increases with increasing dust accumulation.
2. Temperature Impact
The presence of dust doesn’t directly increase or decrease the temperature of the solar panel. Rather, dust adheres to the surface of the module, increasing its thermal resistance and indirectly affecting the panel’s heat dissipation efficiency. Silicon panels are highly sensitive to temperature, so this impact is significant. The higher the temperature, the lower the panel’s output power.
In addition, because areas covered by dust heat up faster than other areas, excessive temperatures can lead to hot spots, which not only affect the panel’s output power but also accelerate aging and even burnout, posing a safety hazard.
3. Corrosion
Dust also has a corrosive effect on solar street light components. For glass-surfaced solar panels, contact with moist, acidic, or alkaline dust can easily trigger a chemical reaction, corroding the panel surface.
Over time, if dust is not cleaned promptly, the panel surface can easily become pitted and imperfect, affecting the transmission of light, resulting in less light energy and, consequently, lower power generation, ultimately impacting output.
Dust also attracts dust. If not cleaned promptly, the accumulation of dust increases and accelerates. Therefore, it’s crucial to regularly and effectively clean solar panels to ensure efficient solar street light generation.
We need to develop a regular cleaning habit.
Use a soft cloth to wipe and clean; never use hard or sharp tools like brushes or mops to avoid damaging the street light. When cleaning, wipe in one direction with moderate force, being especially gentle with delicate components. If you encounter stubborn stains that are difficult to clean, you can use a detergent. However, be careful not to use detergents that may corrode the solar powered street lamps. Instead, choose a neutral detergent to better ensure the quality of the solar powered street lamps.
