PV Cleaning & Cooling Robot
Transcript of PV Cleaning & Cooling Robot
In our project, we introduce the idea of a special robot for PV Cells, specializes in clean solar cell from dirt and snow accumulation, as well as to cool the solar cells at high temperature.PV-cleaning robot can be used without need for Human intervention using special sensors for heat and dust. The robot moves on tracks that are mounted on the photovoltaic panel structure.
The effect of dirt
Pollution, traffic dust, leaves and even bird droppings contribute to preventing sunlight from reaching the solar cells in your solar panels The more dirt – the lower amount of electricity they will produce. . That loss may range as high as 25% - 30% .
The effect of high temperature
The energy production efficiency of solar panels drops when the panel reaches hot temperatures. A field experiment in the United Kingdom revealed a drop of 1.1% of peak output for every increase in degrees Celsius of a home photovoltaic solar panel once the panel reached 42 degrees Celsius .
Despite the positive effects of low temperature in the solar energy production, accumulation of snow on the surface of cells leads to blocking access to sunlight, thus reducing the efficiency of the system.
The effect of snow
With the increased use of solar cells for electricity generation . There is a need for automatic methods to clean the cells. And when you see the methods currently used in clean solar cells, and even now is cleaning the cells manually once every 10 days, from here the idea of project is generated .
Cleaning PV-cell from dirt and snow.
Cooling PV-cell in high-level temperature.
Increase the efficiency of the PV Cell
Save time and effort
Reduce the Human resources
Use modern cleaning methods
Reduce the time and effort and money by using sensors .
Clean the solar panel by 75% .
Reduce the panel temperature .
The efficiency of the PV cell increase .
Lack of sufficient forming machines to accomplish a lot of the pieces needed for the project.
Difficulty in getting a lot of the pieces necessary, and to resort to imported from abroad
The mosfet on the drive circuit failed because it couldn’t bear the high current so we replaced it by relay .
We face a problem by using two pumps , so we replace one of the two by a solenoid .
Glass has been used as an alternative to solar panels for non-availability

Solar Energy around the world
Solar Energy in Arab World
Saudi Arabia announced it was raising funds to spend $109 billion on solar energy, in a push to secure a third of its electricity from renewable resources by 2032
Abu Dhabi began operating the world’s largest solar power plant, Shams 1.
Now, solar expenditures are expected to increase 40% year after year through 2017 in the Middle East, South America and Africa
The part of installed capacity of renewable energy will represent 42% of total electric installed capacity by the year 2020
