Solar Panel Cleaning Equipment South Africa
Solar panel cleaning equipment removes the dust and grime that cut PV output, using soft rotating brushes and pure water. PV panel cleaning describes the same job: photovoltaic panels and solar panels are one surface, and both need a soft brush and deionised water so the glass is not scratched. Window Washing stocks a mains-powered rotating roller machine with telescopic reach to 7.5 m, plus water-fed solar brushes and poles from R5,175.00. The rotating machine carries a 2-year warranty on core components, and everything ships across South Africa.

Solar Panel Cleaning: Common Questions
How Can You Clean Solar Panels With A Waterfed Pole?
The waterfed pole is an ideal tool for cleaning solar and photovoltaic systems, as it offers a safe and effective way to remove dirt without damaging the PV panel. It utilises pure water, delivered through a hose connected to either mains or deionised water sources; this results in superior end-results with no risk of scratching the surface. Water fed poles for sale provide a great solution that allows users to quickly clean large areas and reach difficult locations. We offer these systems to the South African market.
The process involves using the telescopic handle and brush head attached at one end, while attaching the other end of the pole to a filtered water source. The brush loosens grime from the surface of the solar panel before being rinsed off with pure water which effectively removes all traces of dust and debris. This simple yet effective technique leaves solar panels looking like new again – ready for maximum efficiency!
Common Mistakes To Avoid During Solar Panel Cleaning
Solar panel cleaning can be a complex process, however it is important to take the time and attention necessary to ensure that your panels are cleaned safely and correctly. There are several common mistakes to avoid in order to properly clean solar panels:
- Not using filtered water – Hard or unfiltered water contains minerals which can leave deposits on the surface of the panel when dried.
- Excessive scrubbing – Be gentle with your solar panel! The top layer of glass is delicate, so use only soft cloths and brushes for cleaning.
- Incorrect pressure levels – Too much pressure from high-powered hoses or sprays can damage sensitive components like wiring insulation and junction boxes.
- Ignoring safety precautions – Safety should always come first when dealing with ladders or other equipment at height. Follow safety guidelines carefully.
How Often Should I Clean My Solar Panels?
Regular maintenance of solar panels is essential to ensure optimal performance. It is recommended that they be cleaned at least twice a year with additional cleanings during winter months, when the accumulation of dirt and debris can reduce efficiency by as much as 25%. Cleaning should include both dry and wet methods; wiping down the surface with soft cloths or rags for dust, bird droppings and other small particles, followed by using a low-pressure water hose for larger pieces of debris such as leaves or branches.
In order to avoid damage to the delicate photovoltaic cells, it is important not to use abrasive materials like steel wool or brushes on the panel surfaces. Additionally, harsh chemicals and solvents should also not be used due to their potential corrosive effects on the components over time. Therefore, mild soap mixed in warm water will suffice for most cleaning needs. When finished, it is advisable to check that all connections are secure so there won't be any unexpected loss of power output from loose fittings.
What Happens If I Clean My Solar Panels With Normal Tap Water
When cleaning solar panels, it is important to understand the potential effects of using normal tap water. Tap water can contain minerals, chemicals and other impurities that can cause damage over time. The main issue with using tap water for solar panel cleaning is that it can leave behind a residue or film on the surface of the panel which could lead to reduced efficiency and output. This is because the films left by normal tap water can act as an insulator, blocking sunlight from reaching the cells and reducing their effectiveness.
The use of deionized (or distilled) water in solar panel cleaning is recommended due to its ability to reduce mineral deposits and other impurities which are found in tap water. These impurities can cause streaks, spots, and other blemishes on the surface of your solar panels which will reduce their performance over time. Deionized water also reduces corrosion, oxidation and other environmental factors which could damage your panels if not properly cleaned regularly.
It is therefore advised that when cleaning solar panels with a Waterfed Pole System, only deionized (distilled) water should be used. This will help ensure that your panels remain in top condition with no residue or film remaining after each clean. Additionally, regular maintenance should be undertaken to ensure that the surface remains free from dirt or debris build-up which could impede the performance of your solar panels over time.
Importance Of Not Using Chemicals To Clean A Solar Panel
The use of chemicals to clean a solar panel is not recommended, as it can be damaging to the photovoltaic material. This is due to the fact that many chemicals contain alkalis, acids and other substances which can damage the surface of the solar panels, leading to corrosion and other problems which reduce the efficiency of the solar panel. It is therefore important to avoid using any kind of chemical agent when cleaning a solar panel.
In addition, some types of chemicals used for cleaning can leave behind a residue on the surface of the solar panel. This residue acts like an insulator, reducing its ability to absorb light and thus reducing its efficiency. Furthermore, this residue can also form deposits which are difficult to remove, further affecting the performance of the solar panel.
Using waterfed poles with purified water is an effective way to clean a solar panel without risking any damage or leaving behind any residue. Waterfed pole systems use filtered water under pressure which helps remove dirt and grime quickly and efficiently while avoiding any potential harm being done to your solar panels. Furthermore, this method does not require additional tools or personnel since one person can easily handle a waterfed pole system alone.
