1.  Should all solar panels be cleaned?

Absolutely yes! Dirt accumulate on the panel surface are blocking the sunlight, thereby reducing electricity output of the system. Local soiling such as bird feces may reduce the solar system’s output. In those systems, when one or some panels within a string is/are dirty, the generating capacity of the entire string will decrease.

 

2.  How often should solar panels be cleaned?

Cleaning frequency depends on the amount of dirt accumulated and varies by location and season. Solar Cleaning robot can be settled for the needed cleaning frequency to prevent even small reduction in generating capacity. Also, a unique module that monitors electric output daily and executes cleaning process upon measured output reduction can be added.

 

3.  How does cleaning affect electricity production?

Dirt accumulation on solar panels reduces electricity output by 3-15% (assuming solar panels that are manually cleaned 8 – 12 times annually). Therefore, maintaining panel cleanliness can bring back those lost electrons and system profit.

 

4.  Can the Solar cleaning robot be used to clean any solar systems?

Generally speaking the answer is Yes, we have different robot items for different kinds of solar plants. The more uniform the structure of the system, and the longer the rows, better economic profitability is expected. It is possible to customize.

 

5.  What is the cost of the cleaning?

The cost of cleaning is determined in accordance with the PV system by a number of variables, the main one being the number of panels in the system. Compared to manual cleaning, robot cleaning cost is much lower. The main difference between robot cleaning and manual cleaning is that the purchase price covers many more cleanings.

Indeed, when cleaned more frequently, automated cleaning expenses are not higher (Because robot electricity is from the robot itself & most robots are waterless), and these expenses are relatively negligible when compared with the gain in system’s output. For more information regarding pricing, please contact us for a consultation.

 

6.  What is my profit from frequent cleaning?

Frequent cleaning means cleaning every day or every several days. This is way more frequent than once a month or once every two month of manual cleaning. Cleaning frequency will be different from system to system because of the dirt accumulation rate. In terms of system output, frequent cleaning will increase the output by 3% – 15% of the ground solar plants, even 20%-25% of the rooftop solar plants which is dirty easily.

 

7.  Is purified water necessary for cleaning the panels? Which water should be used by the Solar cleaning robot?

Water is not necessary for our dry-cleaning robot. When you use the water-cleaning robot, purified water will be recommended for best cleaning results. Tap water are not recommended because of scale buildup on the panels is expected over time, blocking the passage of the sun’s rays, and reducing the electricity output.

 

8.  Is the cleaning done automatically?

Yes. We have the Solar Cleaning robot which activates its cleaning cycle according to a program. Supervision or the presence of an operator is not required during the process.

 

9.  Is The Solar Cleaning robot eco-friendly?

Definitely yes! The Solar Cleaning robot is working at dawn or at night to make sure not block the solar rays. Also, the cleaning robot will generate electric by the solar plane & storage the electric itself, no need external electric power. And it’s waterless working to save water cost.

 

10.  Does the cleaning require use of soap?

No, soap is not needed. Frequent cleaning with purified water followed by brushing maintains the panels clean.

 

11.  Why does the automatic cleaning system superior to manual cleaning?

a. Frequent cleaning prevents decrease in electricity production due to dirt on the panels.

b. Installing the bridge-wares is a more efficient arrangement to maximize number of panels used, and increase profit.

c. The system can be cleaned daily or as needed, at no extra cost (except for maintenance).

d. Installing an automated system prevents the risk of working at heights and the risk of electric shock.

 

12.  Does the system require regular maintenance?

Yes but no. Most of system components are designed to work for many years without maintenance and maintenance frequency depends on cleaning frequency. Mainly, Brush will be replaced every three years and check every half year; battery every five years, motor every ten years.
