#1 – Best Solar Panel Performance Test
The bases of the study are the following:
- Sample of more than 12,000 photovoltaic installations.
- Analysis of production samples since 2010.
- Official data of the Italian Electricity Network Agency (GSE)
- Official radiation data obtained from the Eumesat (European Organization for the Exploitation of Meteorological Satellites)
Starting from this base, with official data, we continue with the article’s exposition.
The question we always ask before buying solar panels for a photovoltaic system is:
Will I achieve good performance throughout the 25-30 years of my installation life?
To answer this question, we must seek and contrast many information, most of which are only paper data, without much empirical evidence of real performance.
This question already has an answer !!
As we said, the Italian online monitoring company “SunReport” has been reviewing, investigating, contrasting and collecting production data of more than 12,000 photovoltaic installations in operation since 2010.
The results of these years of work have been reflected in a published study showing the performance of these photovoltaic plants.
In the study, photovoltaic projects have been included in operation, where the best brands have been:
Many other renowned brands such as Luxor, Axitec, Amerisolar, Jinko, Yingli Solar …. Did not appear in the publication, because their performance was much lower than the average.
This has been empirically confirmed by the independent online monitoring portal “Sunreport”, which compared the performance data of solar energy systems throughout Italy and giving the SolarWorld brand outstanding in its performance results.
The results show once again that quality always pays off.
#2 – What has been the result of the solar panel performance test done by SunReport?
Here is an image of the best-positioned manufacturers that speaks for itself:
As can be seen, the solar panels with the best performance obtained in the solar plants in operation are SolarWorld and only surpassed by Sanyo (Panasonic).
It is true that Sanyo modules was HIT technology, therefore, being strict, for the standard crystalline technology, SolarWorld solar panels are, by far, the manufacturer that obtains the best performance.
Of course, other brands, as Aleo, SunTech or SHARP pv panels, between others, are really good performance too. In fact, we can appreciate that SunTech is the best Chinese solar panel performance. We could say, this list could show us a background of the probably best solar panels in the world.
It is important to remember again that the data shown in the image have been the result of the analysis of more than 12,000 photovoltaic installations in operation since 2010-2012. It has been made with official data from the Italian GSE network. And that the data for the calculation of the radiation have been obtained from the Eumesat(European Organization for the Exploitation of Meteorological Satellites).
That is, they are official data and with complete reliability.
The conclusion we can draw from this study on the performance of the best solar panels:
As it has been demonstrated, the quality can be somewhat more expensive, but it compensates widely if we consider the useful life of a photovoltaic system.
You only need to make some numbers and draw conclusions than it can assume to have a production of an average annual 10% more solar panels with SolarWorld compared to the average performance of solar panels of the other manufacturers shown in the study.
