#PluginSolar in the #UK can never work its far to cloudy! Germany is much more sunny.

That is wrong: #London is on the same Latitude as #Dortmund. #Hamburg on the same Latitude as #Manchester.

Let’s do some math: We got to re.jrc.ec.europa.eu/pvg_tools/… works for the Great Britain, even though you left the EU. And choose London.

We choose 2025 Crystalline Silicon, 0,8 kWp and 14% system loss. Mounting is 90°, so hanging on a balcony. Azimuth: 0° is South.

As a price we choose equivalent of 500 EUR which is currently 432,92 Pound. 2% interset and 15 lifetime.

Gives us: Yearly PV energy production 614.65 kWh.

Average Price for London is 24.9 p/kWh.

We assume that you use about 50% of that electricity yourself.

600 kwh * ½ * 0,249 Pound = 74 Pound a year.

Gives you a cost return of about 5,4 years.
