Solar modules and equipment operate reliably for years, but the accumulation of dust, pollen, smog, soot, leaves, and bird droppings can gradually reduce light transmission and decrease energy production. In many cases, rain and wind are not sufficient to remove persistent contamination, especially at smaller module pitch.
That is why our O&M approach is based on three key principles: preventive inspections, timely module cleaning, and rapid response whenever irregularities occur. This minimizes the risk of standstill in time, protects the equipment, and preserves the long-term value of the solar power plant investment.

We perform module cleaning using methods that are safe for PV surfaces. Appropriate soft-bristle tools are used, along with demineralized water when necessary, in order to prevent mineral residues and dirt accumulation.
The recommended cleaning interval is typically at least twice per year, although the frequency is adjusted according to site conditions and environmental factors such as dust, industrial pollution, vegetation, nearby roads, and actual production data.
When Is It Time to Clean the Modules?
When a prolonged drop in energy production is noticed compared to the expected seasonal performance.
When visible dirt, stains, dust deposits, or leaves accumulate on the modules – in many cases, a simple visual inspection is enough to determine the need for cleaning.
Inspections and condition of modules, mounting structures, and visible connections to ensure that any deviation are detected at an early stage.

We develop and construct large-scale ground-mounted solar power plants for investors and industrial projects. Our solutions cover the entire process – from project development and permitting to construction and grid connection.
We design systems for maximum energy yield, with the option of fixed constactions or tracker systems, depending on site conditions and investor objectives.

We specialize in the design and construction of rooftop solar systems for industrial, commercial, and public buildings. Rooftop solutions enable efficient use of existing surfaces and provide long-term reductions in electricity costs.
Each system is tailored to the specific characteristics of the building, roof structure, and energy needs of the client, with minimal impact on client business during installation.
