To produce enough energy, solar panels have to be exposed to sunlight. In most cases, rain is usually to enough to keep it naturally clean. However, if you live in an area with a lot of dust and smog, or if your compound has a lot of birds, you have to constantly clean it.
A dirty solar panel may reduce the energy yield by around 25 % because the dirt reduces the amount of sunlight getting through. When you decide to clean your solar panel, you can hire cleaning professionals, or you can do it yourself.
If you are a Melbourne resident, Melbourne solar cleaner is the best solution. If you live in a drought-prone area or a place where the solar panels get dirty often, it is best to clean your panels yourself. It saves you money, time, and it is convenient.
It is also easy because you have most of the things you need and if not, you can get them from the nearest stores. You should also always ensure to read the manufacturer’s instructions and recommendations for cleaning the panels.
In as much as it saves some money, there are some risk factors that you may encounter like;
1. Injuries and damages
Solar panels, being on the roof, needs you to be on the roof when cleaning. That in itself already poses a lot of risks because you may fall off the roof and break a bone or two, especially without the proper safety equipment like safety ropes.
You might also be exposed to the risk of getting hurt by the roof. If your roof is old, some of its parts may have come off, especially if it is made from iron sheets or bricks. Some of the damaged parts may cut into your skin, causing a lot of harm.
Before cleaning your solar panel, ensure that you have taken all the safety precautions and have all the safety gear and gadgets needed. To avoid most of the injuries, try cleaning the solar panel from the ground.
You might also cause damages to the panels, for example, if the water gets on the inside of the panels. You might also damage it in your efforts to remove it from the roof to clean it on the ground.
2. Using the wrong materials
Solar panels, just like any other electronic gadget, are delicate, especially when it comes to their maintenance and cleaning. The materials you use to clean your solar panel will determine how clean it will be and its functionality.
Do not use a hard brush to scrub it, but instead, use a soft brush or a sponge. You should also avoid using soap when cleaning your solar panel because soap will leave a residue or a film on it, which will shade the panels and encourage the faster build-up of dirt.
You should also ensure not to use metal materials on the panels because they can scratch on the surface of the panels.
3. Using the wrong cleaning methods
How you clean the panels will also determine how clean they will be and how effective they will be after the clean. You may have the right materials, but the cleaning methods may be wrong.
While you are advised to only use water while cleaning your solar panels, the pressure of the water matters. You might find it hard to attain the pressure that will effectively clean the panels and not damage them.
Too high water pressure may damage the panels by breaking the glass, and too low pressure might not entirely clean the panels.
4. You may not clean the entire panel surface
Solar panels may be large, and there are some corners you may not reach while cleaning it yourself. If you do not have the right equipment to help reach those corners or reach the entire panel, those uncleaned places will be damaged faster and easier than the clean parts.
5. Cleaning them under unfavorable weather conditions
Experts know when to clean the solar panels and the dangers that may be involved by washing them under harsh weather conditions. Since solar panels are made of glass on the top, washing them under very high temperatures will damage them.
The high temperatures will cause high temperatures on the glass on the panels, and when you wash them with cold water, those extreme temperature changes will cause the glass to crack.
Also, the water will evaporate before you can do any cleaning, which leaves a lot of dirty watermarks on the glass.
