Photovoltaic power stations operate outdoors for long periods，and panel surfaces are highly prone to accumulating dust，bird droppings，mud and sand，fallen leaves and other debris。Many power station O&M teams overlook routine cleaning；seemingly minor dirt blockage can continuously reduce module power generation efficiency，causing substantial losses in power generation revenue over time。Implementing regular photovoltaic panel cleaning is the simplest and most efficient way to improve power station revenue and extend module service life。

The actual impact of dust and dirt on photovoltaic power generation

Based on industry field test data，even light dust accumulation on photovoltaic panel surfaces can cause 8%-15% power generation loss；in areas with frequent sandstorms and on photovoltaic panel surfaces that have not been cleaned for a long time，power generation loss can reach more than 30%。

Localized stubborn dirt can also trigger the module hot spot effect，which not only reduces power generation output，but also accelerates the aging of photovoltaic modules，shortens the overall service life of the power station，and leads to extremely high later-stage maintenance and replacement costs。

Comparison of three mainstream cleaning methods

Traditional manual cleaning：Costs are rising year by year，cleaning is uneven，there are many cleaning blind spots，and it cannot adapt to regular O&M for large-area power stations。

Simple handheld tool cleaning：Suitable for very small-area photovoltaics，time-consuming and labor-intensive，with relatively low overall O&M efficiency。

Intelligent automated photovoltaic cleaning equipment：Covers photovoltaic power stations in all scenarios，provides uniform cleaning with no dead corners，uses soft bristle brushes that do not damage the photovoltaic coating，requires no large amount of manual on-site supervision，and maximizes cost-effectiveness for long-term O&M。

For photovoltaic power stations to generate stable revenue，they cannot rely only on upfront equipment investment；regular O&M cleaning in the later stage is equally critical。Our company covers remote-controlled robots，suspended fully automatic cleaning machines，and multiple handheld cleaning devices，adapting to all-scenario needs of ground-mounted power stations and rooftop distributed photovoltaics，providing a one-stop solution to photovoltaic panel cleaning challenges and steadily improving the overall power generation revenue of power stations。
