In addition, self-cleaning of the solar power system will not ensure the best performance and may cause unfortunate incidents. Because inexperienced cleaners, qualified techniques and tools will lead to undesirable results. Moreover, the cost of cleaning yourself is not necessarily much more economical than hiring a professional solar system cleaning unit.
Understanding this, Intech Energy in addition to installing solar power systems, has also deployed solar power system cleaning services to assist customers in maintaining cleaning and maintenance. system in a comprehensive way, bringing the highest satisfaction to customers. Annual losses due to failure to clean or fail to clean the solar power system regularly range from 2% to 5%. That's why you need to know how often and when to clean your solar panels.

Solar panel cleaning process
Here are the important steps in the solar panel cleaning process:
- Starting in the morning (about 6-7 o'clock) is the most suitable time.
- Disconnect your PV array from the inverter by turning off the DC switch in the system electrical junction box.
- Get some distilled water and mix it with some dish soap or specialized solution for effective cleaning.
- Look for a soft brush or sponge to start cleaning PV panels with the above aqueous solution.
- After cleaning all with soap solution, we will rinse with water with low pressure spray.
- Let the modules dry we wait about 30 - 45 minutes and then turn on the DC switch again.
As you can see it's a fairly simple process, so schedule a regular cleaning of the solar panels to maximize the power output of your household.
Notes on cleaning the solar power system
Here are some notes when cleaning a solar power system:
Turn off PV system
The first step that you need to think about before cleaning is to turn off the DC switch located in the combo box. This is essential for your safety and to ensure that the solar panels are not damaged by water inside the junction box, exposed wiring or broken sealing while DC current is flowing. through the system.
New PV systems are now required to have a quick shut-off system, which will instantly reduce the voltage of the PV array to zero from an easily accessible location in a home or business. This will ensure security in all cases for homeowners or businesses.
Always remember to press that red button in the quick shutdown box before going to clean your solar panels.
Use the right tools
When cleaning solar panels, it is essential to use the right tools. The glass of a solar panel is hard but using abrasive materials can scratch the glass surface, reduce its performance, or even damage the module.
If your systems are installed above ground, then you can choose to use a simple sponge to clean them or a soft brush. However, if they are on the roof, then you must use a soft brush in combination with a long extension to make the job easier and safer from the ground.
Avoid using water with high mineral content
Module manufacturers recommend using distilled or deionized water to clean the panels. Mineral-rich water can leave particles deposited over time and its chemistry is not recommended for modules.
If you don't have access to deionized or distilled water, you can use a water softener hose attachment to filter those minerals.
Do not use high pressure sprayer
Using a direct-injection high-pressure pump to clean panels may force water into a junction box or plug that is not 100% sealed. As a general approach, it is recommended that when a hose is used, the pressure remains below 40bar.
It is also advised that jet cleaning creates a spray plate at the nozzle to reduce the pressure received by the glass.
Use water with the right temperature
Manufacturers do not recommend using cold or hot water to clean the panels. The reason behind this is that sudden and drastic differences in temperature can crack the glass surface.
It is best to clean your panel system with ambient temperature water in the early morning (6-7am), when the modules Temperature will be low after cooling down overnight and when the solar generation not started yet.
It is not recommended to use abrasive materials to clean solar panels
Sometimes the homeowner or salesperson may recommend using detergent to clean the modules. However, all you really need is dish soap and water to clean them.
Cleaners designed for other purposes should not be used as they can create moisture or delamination at the solar panel level, which will void the warranties of the panels and will definitely damage the panels. spoil them.
Never walk on modules
The panels are designed to withstand specific wind and dispersed snow loads. If your concentrated weight is higher than the design load, you can cause cracking, which degrades the module's performance over time. Besides, the surface can be slippery, and if you add soap and water to the mixture, the probability of falling is quite high.
