The results of the Fraunhofer Institute show that many solar panels do not provide the strength that promises it, and this is a big problem for them Your wallet And the future of our energy, according to a summary of the institute on Xplore Technology.
You expect to get what you pay for Buy solar panels. However, the research conducted by the respectable Fraunhofer Institute in Germany for solar Solar Systems ISE reveals that many low -performance photovoltaic units compared to the manufacturer’s demands.
The researchers found a disturbing pattern after analyzing more than 70,000 solar panel measurements made since 2012: before 2016, solar panels usually meet or exceed energy classifications. Since then, the actual performance has increased increasingly below the declared levels, as 2023 shows that the panels are 1.3 % on average.
“Since then, the data has shown a negative direction,” said Daniel Philip, head of the Fraunhofer ISE department and reliability unit description. “During the year 2023, this was crowned with a negative deviation between the manufacturer’s specifications and our review of about 1.3 %. A positive deviation has not been observed at all.”
The latest data shows the minimum improvement. “In 2024, we noticed the slight reflection of the direction, but on average still strong negative deviations of 1.2 %,” Philip explained.
If you are installing solar energy, you may get less energy than you have paid it. It was applied to solar additions in Germany 2024 alone, and this deficiency is equal to 1.2 % about 195 MW, equivalent to one of the largest solar gardens in Germany.
“The results also show the importance of reliable, continuous and independent infrastructure to monitor quality in the photovoltaic units,” said Professor Andreas Pitt, director of the institute at Fraunhofer ISE, especially when German and European photovoltaic markets depend on 90 % on the PV pore document. “
This research emphasizes the reason for the importance of the independent test, especially since more people resort to solar energy to reduce their electricity costs and reduce air pollution. With the prosperity of solar installations around the world, sincere energy classifications are needed so that consumers can choose wisely.
Currently, if you shop for solar panels, think that the advertised electric power may be optimistic. Look for strong reputable manufacturers and request an independent performance to ensure that you get out of the clean energy you pay.
