If there is one thing that we all have learned during the coronavirus pandemic, it is the utility of soap and water. Despite offense being the best defense, earlier, regularly washing our hands was our best defense. A few dirty solar panels are indeed benefitted from regular washing to prevent minimized output and efficiency. Soap wouldn’t be a viable option here.
Most of the leading solar panel cleaning services in California never apply any cleaning agent on solar panels. Rather they depend on a rotating-brush system and deionized water for washing solar panels.
Soaps may leave a film or residue that not just shades panels such as the dirt that was just washed off but may encourage dirt as well to stick and accumulate faster. Many professionals make use of deionized water that is applied through the rotating-brush system. This is the most ideal method to leave the solar panels with a spot-free shine that’s as appealing as it was on the day of their installation.
Instead of risking the safety of the professional or possible damage to the solar panels they’re cleaning, many companies use Sola-Tecs brush cleaners over the last three years. What they do is fix a rolling brush to the wheels for gliding across the solar panels, letting a nearly hands-free deep clean. Many professional experts run the customer’s water through a demineralizing and ionizing system.
Many companies use only the Sola-Tecs cleaning system. It has been observed that in combination with the water treatment process, it’s the most ideal method for cleaning solar panels. You need fewer passes, less water, and no detergents or harsh chemicals. You must always remember that if you are habituated to smell your hands after washing them with soap, you only smell the soap that is left behind, even though you don’t see any soap later on. Now, if you contemplate using soap for cleaning panels, the very small molecules of soap would be left with something behind for dust and dirt to accumulate.
While they are occupied in cleaning solar panels in California, a lot of companies provide a complete maintenance suite, including infrared inspections for tracing the damaged panels that require more than just a good wash. If you are residing close to the airport and highways, then the panels accumulate smog or oil-based pollution, which resist running off with normal rainfall. These make a few of the older blue panels seem to black at a first glimpse. Any accumulation of dirt on the surface will reflect the light away from the panels. A clean panel stays cooler, letting the flow of electrons move more effortlessly. In such a scenario too, it is better to stay away from the soap. You can use filtered water and a rotating brush to clean such panels. Certain companies use a blend of hydrogen peroxide and diluted vinegar to facilitate scrubbing away any dirt or grime.
Often, it isn’t enough to apply water. However, everyone agrees unanimously that soap should never be a tool. That’s the reason why lubricant manufacturer Polywater launched their Solar Panel Wash almost six years back. It is a heavily concentrated additive, which isn’t at all a filmy soap. Rather, it enhances the ability of the water for cleaning solar panels. If you apply it, then you will find that you give the water some capacity to lift the soil off the panel contrary to a solvent, which is mostly adjoining the dirt particle, and take it off the panel. Moreover, Solar Panel Wash works fine for the components of the panel. It’s won’t impact anti-reflective films. It won’t corrode the aluminum rails. It’ biodegradability implies that it’s non-persistent, making it environment friendly. It won't impact the groundwater. Additionally, Solar Panel Wash improves the surface tension of the water. That is the reason, rather than water covering up, it will create a continuous film across the solar panels to lift dirt and debris.
Many are installed in desert regions where the availability of water is a major challenge. If we can minimize the use of water, the environment will be benefited. At the outset, panel managers insisted not to use anything but rainwater. People were taking that seriously and then three years after the panel installation they began observing a significant degradation of productivity. For a major installation, when the efficiency goes down by 50%, it means that it is economically unjustified.
Inference
If you own a car, do you wash it with soap? Certainly not! The same logic applies to your dirty solar panels. Just refrain from using soap. Only a little elbow grease and waterwork will be okay.
