What is the ratio of the loss of income caused by the loss of the power of the solar panels to the power loss? Although this ratio is expected to be the correct proportion, the loss of production is more than the loss of power.
First, let’s look at a work we did last week.
I share the IV chart of 10 sample arrays in a SPP consisting of 160 arrays. You can see that the lines that normally need to overlap start from different short circuit currents and follow different characteristics. First of all, we see that the array is facing an incompatibility problem. The power within the power of the arrays converges to the lowest panel. A similar situation has occurred here.
When we look at the measurement values after solar panels control, we see that the losses occurred after deducting the error margins and deviations. In summary, the 270W solar panels are moving between 250-260W. When we get the average of 160 series, we are facing a coverage rate of 95%. On average, solar panels are powered by 256W instead of 270W. This is a very serious difference. At the same time, there are various hot spots and production problems in the physical examination of the solar panels.
Now let’s go to production.
Have you noticed anything? On sunny days, the spread opens even further. In the IV measurements, the solar panels, which we found 95% productivity, fall to 87% in production. As the intensity of the radiation increases and the temperature increases, the internal resistance of the solar panels increases, the effect of the problems arising from the production increases, and the solar panels produce less than expected, and the solar panel which produces the least as it draws down the complete string.
Today, the only problematic panel in the strings consisting of 20-24 solar panels decreases the others. The field in which we conducted this inspection was a little more fortunate in terms of detecting this error, because they were able to determine the difference because there were also regular solar panels in the same facility. What if your entire facility is missing? The only way to find out is to inspect your facility.
