Solar panels are a valuable investment in the energy future of any business or household. But did you know that a dirty panel can lose up to 30% of its performance?

In the Republic of Moldova, interest in solar energy is steadily increasing, but cleaning photovoltaic panels remains a rarely addressed topic. Toreco provides the professional solution: Pannelli Solari detergent – a product specially designed for the safe and efficient maintenance of solar panels.

Why is it important to clean solar panels?

Just like a car needs regular oil changes to operate efficiently, solar panels require periodic maintenance. According to the US National Renewable Energy Laboratorydeposits of dust, pollen, soot, leaves, or bird droppings can reduce energy output by up to 30% annually.Moreover, if dirt hardens (a process called "cementation"), it can permanently damage the panel’s surface.

Common issues that affect performance:

• Dust and pollen deposits (especially in agricultural or construction areas)
• Bird droppings
• Leaves, ash, or other plant debris
• Lack of rainfall during dry periods în perioadele secetoase

The solution: Pannelli Solari Cleaner

Pannelli Solari is a professional liquid cleaner, available in 5 kg format, specially designed for the safe and efficient cleaning of solar and photovoltaic panels,without damaging sensitive materials like silicon, paint, or rubber seals.

Product benefits:

Method of use:

Dilute 5–15% in water, depending on the level of dirt. Apply with a sponge soft, brush long-handled or specialized cleaning equipment.

Professional cleaning vs. DIY – what to choose?

If the panels are ground-mounted, cleaning can be done by the user with simple, non-abrasive tools.For roof-mounted systems, it is recommended to hire professionalsto avoid accidents and damage.

Toreco’s tip: Do not use pressure washers or harsh chemicals — they may scratch or damage the surface of the panels!

How often should panels be cleaned?

The answer varies depending on:

• Geographic area (near roads, construction sites, or agricultural fields – cleaning should be more frequent)
• Weather conditions (in dry periods, dirt accumulates faster)
• Presence of trees or birds nearby

General recommendation:: Monthly visual check + full cleaning 2–4 times per year.

Cost efficiency: a small effort, a big gain

Cleaning your panels is not just maintenance; it is a strategy to maximize your investment.A clean system means:
