First UK Solar PV System 95% Efficient 20 Years Later
The UK’s first grid connected solar system has been tested on its 20th anniversary, to find it still has a 95% generation rate from its initial installation 20 years ago.
The domestic solar system was installed and connected 20 years ago by residential renewable system installers, Wind & Sun. The 2.16kW array is south facing on an oak frame with 36, Solarex 60Wp, polycrystalline modules, and an SMA PV WR-1800 inverter – the first SMA inverter installed in the UK.
After 20 years, Wind & Sun measured solar irradiance and back of cell temperature, while performing a full I-V curve test from open-circuit voltage to short circuit current. With the results a comparison in performance was made against the original panel flash test data when it left the factory.
