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.

A very professional installation. All the staff I met and dealt with were friendly and helpful. Would definitely recommend the Company. Thank you all, 5 stars!!
We found your service efficient and enquiries polite and considerate. I would definitely recommend your services to anyone who is looking for solar, in fact we have another farm building which will be sorted after Christmas, and would think we will be contacting you again. Thank you once again.
I have been very pleased with the speedy and efficient service we have received. Everyone in the Geo Green Power team has been pleasant to deal with and all aspects of the installation were carried out in a timely and effective manner. Many thanks for making our lives easier!
