Shining Bright in Potchefstroom: Why Clean Solar Panels Matter for Homes and Businesses

Potchefstroom and the broader North West province of South Africa enjoy abundant sunshine throughout the year. This sunny climate makes solar power popular for both homes and businesses.
However, the region’s dry, dusty seasons, especially in winter when rain is scarce, can leave solar panels coated with dirt and grime. Cleaning those panels isn’t just about appearances; it’s crucial for maintaining performance and maximizing your return on a solar investment.

Keeping solar panels clean ensures they can absorb as much sunlight as possible, which means more electricity for your property. Dust, pollen, and bird droppings create a film that blocks sunlight, reducing the panels’ efficiency.
In fact, studies have found that accumulated dust can cut solar output by up to 20%, and some experts report losses as high as 25% or more in very dirty conditionsg. That kind of power drop translates to higher bills and a slower return on investment, whether you’re running a large commercial array or a few panels on your home.
Beyond immediate energy loss, cleaning also protects your solar investment for the long run. Dirt and debris left to sit can lead to corrosive buildup or scratches on the panel surface.
Regular cleaning prevents these issues, helping extend the lifespan of your panels and keeping you in compliance with warranty requirements (many manufacturers expect periodic cleaning).
How Often Should Solar Panels Be Cleaned?
Experts generally recommend cleaning solar panels at least once or twice a year. In many cases, a good washing every six months will keep your panels operating at peak efficiency.
The ideal schedule depends on local conditions: in a rainy climate, occasional showers might rinse off dust so annual cleaning could suffice. But in a dry, dust-prone area like Potchefstroom, a biannual cleaning (for example, each spring and autumn) is often best.
This clears any dirt built up over the dry winter and after the windy late-winter period, so you head into the sunnier months with panels that can perform optimally. Of course, if you notice a significant drop in your system’s output or see visible grime, it’s wise to clean sooner rather than waiting for the next scheduled date.
Safety Precautions for Solar Panel Cleaning
Cleaning solar panels is straightforward, but remember these safety precautions:
Shut off the system: Always turn off your solar power system before cleaning. This protects you from shocks and prevents any electrical damage while you work.
Use soft tools: Clean with a soft sponge, cloth, or brush. Avoid abrasive pads or harsh scrubbers that could scratch the glass surface, scratches will hurt efficiency more than the dirt does.
Stick to mild soap and water: A garden hose and a bit of ordinary dish soap are usually all you need to wash panels. Don’t use strong chemicals like bleach (they can damage coatings), and never use a high-pressure spray which could crack the glass or dislodge panel seals.
Clean during cool hours: Tackle cleaning in the early morning or late afternoon when the panels are cooler. If the sun is hot, use lukewarm water (not cold) to avoid thermal shock to the glass.
Watch your footing: If panels are on a roof, use a sturdy ladder and consider a safety harness. Wear shoes with good grip, since the roof can be slippery when wet and of course, never walk on the panels themselves.
Know when to call a pro: If you’re uncomfortable with heights or have many panels to clean, hiring a professional is the safest option. Falls and injuries are a serious risk, so let trained technicians with proper gear handle those tricky jobs.
