Hence this reduces the light transmittance of the solar panel, causing energy loss. It is proven that standard solar panels may lose up to 30% to 40% of their efficiency within one year due to unclean panel surfaces. Currently in the market, the automatic-cleaning solution does not have the capability to remove heavy dirt from panel surfaces. The most common maintenance of solar panels is to manually clean with a brush and solvent. Considering the manual nature of these services, it may be more costly and unsafe
(especially cleaning roof-mounted systems.) our cleaning system targets these problems, making sure your investment in solar energy coupled with our cleaning system will give you the most economical benefit Features 1: Water spray along with wiper, enabling the effective removal of dirt, snows, bird droppings, and other pollutants from the surface of the panel. 2: Once activated, water sprays along the top of the frame, and then a wiper moves down the frame and back up. The cleaning capacity is at maximum 6kgs on the solar panel surface. 3: Our cleaning system can be mounted on multiple kinds of solar panels, new or existing, whether with frame or not. 4: Remote control and programmable settings makes cleaning convenient. 5: Our system has been tested under different climate conditions. It can work well under rain, sandstorm, typhoon, etc. Functions:
The PV systems with our cleaning systems mounted on, provide the following functions:
1: Enable to clean the solar panel effectively, optimize their ability to absorb the solar energy, maintain its efficiency. It is proven that the pollutants attached on the solar panel for 1-5 months, the solar panels conversion efficiency will reduce from approximately 15% to 8-10%. It means that the rate of work decrease up to almost 50%. This is just considering everyday use, excluding heavy snow. Our cleaning systems enable the user to clean the panels surface anytime, optimize their ability to absorb solar energy, keep them working efficiently avoiding 30-40% energy loss caused from the unclean surfaces. 2: Protect the solar panel, minimize the risk of failure As debris and pollutants accumulate on the solar penal surface over frame over time, there is risk of burnout caused from overheating. Cleaning the solar panel often can well decrease this risk, especially in desert areas, or in snow covered areas, there are some pollutants that covers often covers on the solar panel. Removing the pollutants from its surface can well promise the PV system to maintain its good working condition. 3: Guarantee the life time of the other accessories in PV system, and bring down the high economical return. The PV system with our cleaning system mounted on, can work efficiently and stably. Hence it minimize the risk of failures for the its accessories, guarantee that life time. So that it can reduce the budget in the investment for equipment and maintenance. Technical Data:

ID: 01 means its ID is the first one. STATE means the conditions (pass is for success, fail is for failure.) if the state show pass, that means its ID is successfully recorded into the main engine (control box). Then getting the power off; disconnect the extensions (the frame) and the main engine
(control box). And record this frames ID as the first, and takes note on this frame. The same operation on the following extensions (the frame) 2345630. Manual operation If the automatic operation is not workable, it can be operated manually. Firstly connect the extensions (the frame) and the main engine (control box), then get the power on , press the button menu, the screen show as (picture 2), press the button up or down to choose the ID in need , if the state show pass, that means its ID is successfully recorded into the main engine (control box). Picture 1 Picture 2 If the users would like to check the cleaning total working, press the button menu for seconds , then the screen show the states (as picture 3.) RUN CONUTER (5) (means the cleaning total working is 5 times.)
