The quality of the panels has been tested by PVEL
The reliability of the panels was tested, as it is every year, by PV Evolution Labs (PVEL), with contrasting results. A total of 122 panel types from 25 manufacturers were designated as "Top Performers". The "best results ever obtained" in certain categories and more powerful panels were compensated.

Will the photovoltaic industry run out of polyethylene or silicon?
Manufacturers in the photovoltaic industry are in danger of running out of polyethylene, and therefore developers of solar panels. Yet there are many solar power plant construction projects underway in India and China. There is also a possible shortage of silicon.

Dog-shaped robot from 2019 to monitor a solar park
Spain's Acciona has been using a dog-like robot since 2019, instead of drones, to monitor a solar park in Chile. The device has a built-in thermal vision system that generates thermographic reports on the status of the various components of the PV plant, as it walks between the rows of panels following a programmed route.
One drone can carry 5 kilos, the dog three times that. The drones have a range of 30 minutes, the dog three times that, but the drones travel much faster than the dog

An aluminium finned heat sink
Malaysian scientists have developed a multi-level aluminium fin heat sink. These reduce the panel's operating temperature by 8.45 degrees Celsius and increase energy efficiency by 10.75%. The cost of the system has been estimated at $0.60/W.
The heat sinks are made of aluminium alloy. They were glued to the rear face of a 120 W monocrystalline panel. The use of glue is intended to eliminate air gaps and improve thermal conductivity between the cooling system and the panel.

PV Magazine,1 February 2022
Editor's note Reducing the temperature under the panels is often extremely useful for increasing their efficiency. However, the cost of the proposed system seems particularly high, representing twice the price of a panel today and three times the price a year ago! This dooms the product unless it is simplified, or if its price can be lowered through industrialisation. In fact, these multiple fins will quickly come to a halt due to clogging, lack of rotation and the tangled nature of the fins.
