This is the amount of energy the solar system will produce after 31 years

1992 The first photovoltaic system was built in France to feed electricity into the grid. The NGO was responsible for this Hispole.

At the time, the manufacturer promised that the installed solar modules would still have 80 percent of their original output after 25 years. This has now been verified.

Laboratory examination

For this purpose, the solar panels were dismantled and installed Lab Brought, Hispole reports. The usual testing was done there to determine the performance of the solar modules. In a dark room and controlled environment, the units were irradiated with flashes of light. The energy production from this was compared to the value measured using the same method 31 years ago when the solar panels were manufactured.

Result: On average, the solar modules are still there 79.5 percent Its performance. The performance measurement was also conducted when the solar system celebrated its 20th anniversary. At that time, the solar modules were still producing 91.7% of their maximum output.

The oldest solar power plant in Europe is in Switzerland

The result is consistent with other tests conducted in the United States of America, Slovenia and Switzerland. Photovoltaic system Tissot-10 In Lugano, Switzerland 1982 It is connected to the grid and is therefore considered the oldest photovoltaic system in Europe.

After 35 years of operation, solar cells have been measured there and are still being made At least 80 percent the performance. The only problems caused were age-related wear and tear Environmental and infrastructure impacts arise. These include corrosion, damaged connecting cables, and hot spots. This causes parts of the solar modules to overheat, due to partial shading and associated power imbalance or damage to the solder joints.
