As photovoltaic solar energy installations become more and more frequent at the domestic level, the prices of each and every one of the necessary components are decreasing.
Although it is important to say that everything we buy we will not have for the rest of our days.For example, batteries have a certain useful life, and we must replace them every X time.

Time also passes for photovoltaic solar panels, which wear out over time and will gradually suffer a drop in performance. Of course, the quality of it will determine its useful life.
This is very important when sizing our photovoltaic solar installation, since obviously whoever invests in a solar installation wants to obtain an energy yield that is useful until the moment in which we have to replace our installation.
During the time in which the panels are losing performance, we must develop methods to be able to measure the wear they suffer due to changes in temperature, dirt, inclement weather, or the effects of ultraviolet rays.
If we inspect the cells of our photovoltaic solar panel from time to time, we will be able to reduce possible losses and maintain, as far as possible, their performance.
Why are Solar Panels Important?

And then what should we do to know the efficiency status of our photovoltaic solar panels? Today, many professionals in the sector work in numerous methods.
Indian engineers such as Parveen Bhola and Saurabh Bhardwaj from the Thapar Institute of Engineering and Technology have dealt with this problem for years, managing to develop statistical methods based on machine learning. These allow us to examine our solar panels in real-time.
These researchers have developed a method that, through grouped computation, makes use of historical meteorological values with which they measure degradation and performance ratios.
Solar Energy in Pakistan Thanks to this system, it is enough to know the location in which we have our solar installation, thus avoiding having to analyze our equipment on site.
The method developed takes into account aspects as different as humidity, the hours of sunshine, the solar energy that we have, the pressure of the atmosphere, the temperature, the day of the year in which we are, or the speed of the wind, for example.
By taking into account each and every one of these values, the algorithm developed offers us predictions as to what the performance of our installation will be as the days go by.

Until recently, the method that was used required an inspection of our solar panels in the location. where they were installed, which implied a high cost and also did not allow us to know the status of our installation in real-time. Instead, this method gives us an estimate of the degradation of our equipment and the loss of performance in real-time.
By means of this system, we will be able to determine with a greater possibility of success, what should be the energy that a panel or several of them produce at a specific moment, considering what degradation they should suffer.
In this way, by analyzing the energy generated, we can know if our solar panel is working optimally or not, being able to carry out maintenance. if necessary (for example, in the case that the panel is receiving shadow from some element, or because it is dirtier than it should, etc).
