Dust, bird droppings, fallen leaves, and city smog form a thick layer on the solar glass that can reduce your electricity yield by over 20%. <\/p>\n<p>We offer the service of manual washing of photovoltaic panels. This is the safest, most precise and gentle cleaning method that ensures that every corner of your investment will work at 100% of its capacity. <\/p>\n<p><strong>Why is manual cleaning the best solution for your roof?<\/strong><br \/>\nHand washing allows for an individual approach to each panel and is indispensable in a number of situations:<\/p>\n<ul>\n<li><strong>Maximum precision: <\/strong>The human eye notices even the most stubborn dirt (such as dried resin, bird droppings or calcium deposits) that automated machines often miss.<\/li>\n<li><strong>Ideal for complex roofs: <\/strong>Whether the panels are installed on a pitched roof of a house, a guest house, or on a specific structure, we find a safe way to access them.<\/li>\n<li>Complete safety for the equipment: We use special carbon telescopic levers and certified soft brushes. Since the pressure is controlled entirely manually, there is no risk of microcracks in the cells or damage to the aluminum frames. <\/li>\n<li><strong>Attention to detail: <\/strong>We clean not only the glass, but also the frames, where mud most often accumulates, preventing water from draining.<\/li>\n<\/ul>\n<p><strong>Professional technology without traces and stains<\/strong><br \/>\nTo guarantee a perfect result, we never compromise on washing technology:<\/p>\n<ol>\n<li><strong>Use of purified water: <\/strong>We work with filtered (softened\/demineralized) water. It does not contain limescale and minerals, which means that after drying, there are no white spots or streaks left on the panels. <\/li>\n<li><strong>No aggressive chemicals: <\/strong>We use only specialized, environmentally friendly biodegradable preparations (when necessary) that are completely safe for the anti-reflective coating of solar glass.<\/li>\n<li><strong>Safe temperature: <\/strong>We take thermal shock into account &#8211; washing is done early in the morning or on cloudy days to avoid the risk of cracking of the panels heated by the sun.<\/li>\n<\/ol>\n<p><strong>Who is the service suitable for?<\/strong><\/p>\n<ul>\n<li>Private homes and villas: Small installations from 3 to 30 kWp.<\/li>\n<li>Small and medium-sized enterprises: Rooftop power plants on warehouses, offices and shops.<\/li>\n<li>Specific ground structures: Where the space between rows is too narrow for tractors or robots.<\/li>\n<\/ul>\n<p><strong>Price for manual cleaning of photovoltaic panels<\/strong><br \/>\nPricing is determined based on the number of panels. Restore maximum performance of your system now!
