Germany has smothered itself in solar panels, adding more last year than at any time since 2013. Last year they contributed a tenth of the country’s total electricity. Most generation happens in the summer. Owners will know that this is a peak time when their panels feed into the grid to earn their keep. In our exercise carbon saved in the grid returns to homeowners. With that assumption the carbon footprint of an average family home consuming 3900 kWh per year is covered almost entirely by a 4kw home solar system in both countries. Due to less sunlight, 12 or so panels work about a tenth less effectively in the UK compared to Germany. But the UK’s cleaner power grid — about half the carbon intensity of Germany’s — means smaller carbon footprints from powering British homes. Including those calculations, plus the carbon cost of production for panels, our 4kw home array saves almost 700kg of CO2, or 84 per cent of a UK home’s annual power-related carbon footprint. Germany’s dirtier grid lifts the CO2 saving to 90 per cent. Even in murky settings, using solar can boost a home’s carbon credentials.

Switching to solar power could save people in Brighton and Hove almost £200 on their electricity bills, according to new research. The study, which compared Britain’s 30 biggest cities, also found that the relatively sunny local climate meant that Brighton and Hove consumers could save more than anywhere else.
