A misconception is that solar power performs dramatically worse in the UK than in Germany due to latitude. That is wrong, London is on same latitude as Dortmund, while Hamburg is on the same as Manchester. Solar potential is more comparable across these regions than many assume. To evaluate the viability of a small solar installation in London, we can use the EU’s PVGIS calculator (which still works perfectly fine for the UK). Let’s define a realistic small-scale setup: London scenario Using these parameters, the system yields: Annual energy production: 614.65 kWh This is a solid output for such a small installation, and there is really no need to tilt „better to the sun“ as that would only increase summer output, where we already have enough energy. Keep it vertical and catch the winter sun! Now let’s translate that into economic terms: Assuming half of the generated electricity is used directly: gives you a usable energy: 600 kWh × 50% = 300 kWh whtich translates to Annual savings: 300 kWh × £0.249 ≈ £74 per year. With annual savings of about £74: you get a Payback time: ≈ 5.4 years. Even in London’s climate—and with a less-than-ideal vertical installation—a small … Can pluginpv work in the UK? weiterlesen
