The truth is, solar panels work on light, not just direct sunlight. Even on overcast days, panels continue generating electricity—just at slightly lower efficiency. Countries like Germany and the UK, which have similar weather conditions, have some of the highest solar adoption rates in Europe. So yes, solar panels do work effectively in London.

Myth 2: Solar Panels Are Too Expensive

The idea that solar installations are unaffordable is outdated. Over the last decade, the cost of solar panel systems has significantly decreased.

Properly matched to your energy consumption, solar panels can power almost everything, from lights and appliances to heating systems.

Myth 4: Maintenance Is Complicated and Expensive

Contrary to popular belief, solar panels require very little maintenance. They have no moving parts and typically only need an occasional cleaning to remove dust, leaves, or bird droppings.

Moreover, your home remains connected to the national grid, ensuring consistent energy availability regardless of solar output.

Myth 9: Solar Panels Are Bad for the Environment
