Do solar panels work in winter?

At this time of year, many people wonder whether solar panels will continue to work during the winter months. The fact is that while they are generally not capable of producing the same levels of energy as is the case during spring and summer, PV solar panels still produce a significant amount throughout the colder months of the year.

One of the most widespread misconceptions about solar power is that it requires heat. In fact, solar energy is drawn and converted from the light of the sun, not its warmth. PV solar panels are designed this way in order to ensure they can provide a consistent level of energy whenever possible. As long as the panels are exposed to some level of daylight throughout the winter, energy will be produced.

However, as we mentioned, the panels do tend to produce less power in these months. With the sun typically lower in the sky and shorter daylight hours, the PV solar panels do not get struck by as many light particles as in other seasons. Most tests and measurements indicate that in winter a PV solar panel can be relied on to produce around about 25% of the energy it would during summer months. This does at first seem like a significant fall off in output, but ultimately it underlines the point that solar power really does work throughout the entire year.

As leading electricians in Derbyshire, we can always be trusted to position and fit PV solar panels in a way that allows them to give you the maximum level of efficiency possible. With storms and seasonal weather causing disruptions to supplies from the national grid over winter, the power produced by these panels may well be enough to ensure that you are able to keep the lights on at all times.
