At SolarTherm UK, we’ve been helping homeowners across the South East and East Anglia (and the wider UK) switch to solar for over 15 years. One of the biggest challenges we face isn’t the technology itself, it’s the misconceptions about solar panels that still exist.
From whether solar panels work in cloudy weather to worries about costs, many myths are stopping households from making the switch. At SolarTherm UK, we’re here to set the record straight and respond to the most common solar myths we hear across Essex, Kent, Suffolk, Norfolk, Hertfordshire and Cambridgeshire.
Solar Panels Don’t Work in Cloudy Weather or Winter
Many homeowners still believe solar panels only work on hot, sunny summer days. In reality, solar panels work better in cooler temperatures on bright days, but also work on cloudy or overcast days, just at a lower efficiency. While output is higher in direct sunlight and the summer months, modern solar technology is designed to capture sunlight in all conditions.

The graph above shows a SolarEdge system installed in July 2020, showing solar generation each month since install. The graph shows that although generation is lower in winter months, there is still a substantial generation, meaning electricity bills will still see a reduction.
Solar Energy can Only be Stored in Hot Countries
Some people believe solar battery storage is only possible in the desert or hot climates. That’s simply not true – solar battery storage can be used in any climate, allowing you to store surplus energy for use in the evenings or on a low generation day. Whether you live in Chelmsford, Cambridge, Norwich or anywhere in the South East, a solar battery gives you the ability to have access to free electricity around the clock. The more electricity you use that is generated by your solar panels, the less you rely on expensive grid electricity, taking back control of your energy bills.
