Solar panels are photovoltaic panels made from photovoltaic (PV) modules consisting of photovoltaic cells (Solar cells) connected together at different voltages and capacities. . They play the role of collecting energy and converting the energy of sunlight into electricity to supply in commercial and residential applications, which are one of the basic components of a solar power system.
Solar cells rely on the photovoltaic effect to perform the process of converting photovoltaics into electrical energy. The main ingredients include:
This is the heaviest component of the panel, the glass layer is 2-4mm thick, is tempered glass to ensure durability, plays a protective role for the entire panel, especially the battery cells inside. This glass layer must be transparent to transmit the spectrum and light.
Photovoltaic cell class:
This is the main component of the battery that plays the role of absorbing sunlight to generate electricity.
Placed on the back, the white layer, usually made of a plastic layer, acts as electrical isolation and protection for the PV cells against the effects of humidity or weather that reduce the durability and performance of the panels.
Behind the panel there is a PV junction box that acts as its output interface.
The frame is made of metal, usually aluminum, to ensure lightness and durability.
Because of the specific layout in high positions, spacious space to receive maximum sunlight, solar panels continuously accumulate dust, dirt and garbage. The huge number of solar panels lying on the roofs of tall buildings or in remote areas always causes people to have a headache: how to clean them, because once the surface of the panels If it is dirty, its performance will decrease. Using manual labor to clean solar panels is both inefficient, costly and dangerous.
That is why researchers came up with the idea of using drones to serve the purpose of cleaning solar panels.
This “drone in the box” drone system is the result of a partnership between solar farm maintenance company Solar Drone and drone maker Airobotics – both companies. of Israel.
The system consists of a quadcopter, housed in a weather-resistant docking station and placed next to solar panels. At pre-set intervals, the two doors on the dock lid will regularly open for the drone to fly up. The drone is fitted with the necessary machinery to clean the solar panels.
Thanks to the use of advanced positioning technologies such as LiDAR sensors, mapping cameras, etc., these drones will be able to self-align their positions above each solar panel, spraying chemicals to clean and then continue to clean other panels.
After completing the mission, these drones will return to the charging dock and land automatically. In case the battery runs out or runs out of cleaning chemicals, a robot system will remove the dead batteries to install a fully charged battery, and at the same time replace the empty chemical tanks with new ones. All will be done automatically to minimize the need for human intervention or supervision.
