Why Winter Is The Best Time To Install Solar Panels in the UK

When we think of solar panels, we tend think of summer with long sunny days easily generating masses of electricity for our home. But what many don’t know is that solar panels work all year round – even in winter! In fact, installing solar panels in winter might be the best decision you’ll make for your home. Let’s get into why winter is the best time to go solar and how you’ll benefit short and long term.

Winter Solar Myths

One of the biggest reasons people don’t install solar panels in winter is the myth that they won’t work efficiently during the colder, darker months. Many homeowners think solar panels need direct, intense sunlight to work properly but that’s not the case. Well, we call out this nonsense!

Solar PV (photovoltaic) panels generate electricity from light, not heat. They work by capturing photons from sunlight – even on cloudy days. Yes, it’s true that output will be lower in winter due to fewer daylight hours but solar panels in winter will still produce energy as long as there’s daylight. In the UK where sunny days are rare regardless of the season, solar panels are designed to make the most of any available light – whether it’s January or July.

Winter Performance of Solar Panels

It might seem crazy but solar panels in winter can actually perform better in certain conditions. Solar panels are sensitive to temperature and extreme heat can reduce their efficiency. The cooler temperatures of winter combined with sunlight means solar panels can work at optimal efficiency without the risk of overheating.

Although the days are shorter and there’s more cloud cover, solar panels are very good at capturing diffused light. Even on cloudy days, they can convert ambient light into electricity, making them highly efficient even when the skies are grey. So even on overcast winter days in the UK, solar panels will still produce electricity. The idea that panels “stop working” in winter is a myth – winter might reduce the total energy production slightly, but solar panels are still working to power your home.

Winter Installations

Another reason to install solar panels in winter is availability. Many homeowners wait until the warmer months to install solar panels, so spring and summer is peak season for installers. Winter is usually quieter for solar installers, so you’ll find more flexibility in booking your installation.

This also means faster installation times as installers have fewer jobs on their books. And with some companies offering winter discounts or promotions you could save even more by installing in the winter.

Save on Energy Bills for Spring and Summer

By installing solar panels in winter you’re preparing your home to make the most of the brighter spring and summer months. Once your system is installed it will start generating electricity immediately. Even if winter days are shorter the energy your system produces will start to offset your energy bills.

And when the longer days of spring and summer arrive your system will already be in place and ready to go. You’ll have a head start on energy savings. And you’ll already know your system is working well and how to monitor it so you’ll be fully prepared when the high solar production months come around.

Maximise Government Incentives and Schemes

The UK government is still promoting renewable energy through various schemes for homeowners who install solar panels in winter. These schemes can help reduce the upfront cost of solar panels and make the switch to renewable energy more affordable.

By installing in winter, you can use current schemes and avoid any changes or reductions that may happen in the next financial year. By acting now you’ll lock in any available grants or tax breaks and be ahead of any future policy changes.

Winter Installation is Safe and Reliable

Some homeowners worry that installing solar panels in winter will be more complicated or result in a lower quality installation due to the weather – rain, snow or ice. But professional installers are equipped to handle winter. They’re trained to install solar systems whatever the season.

Winter weather doesn’t affect the installation itself. Whether it’s rain or shine reputable solar installation companies will ensure your panels are installed securely and efficiently so they work optimally from day one.

Do Solar Panels Work in the Snow?

Snow in the UK is minimal but it’s natural to wonder if solar panels in winter will work if there’s snow on the roof. Luckily snow doesn’t usually pose a problem for solar panels.

Firstly, solar panels are installed at an angle so snow will slide off naturally. Secondly solar panels generate heat whilst they’re in operation which will melt any snow that settles. If snow does accumulate it can usually be cleared without affecting the panels themselves. And because of the angle and design of the panels snow has little impact on long term performance.

Energy Self Sufficiency: Get Ahead of Rising Energy Costs

With energy prices rising energy self-sufficiency is a tempting idea for many UK homeowners. Installing solar panels in winter means you can take control of your energy bills and start saving now. By generating your own electricity you’ll be less dependent on the big six and more protected from future price increases.

Winter is the perfect time to install solar panels because you’ll be ready to generate your own electricity as soon as the sun comes out and maximise your savings.

Solar Batteries: Store Energy in Shorter Days

One of the best ways to get the most out of solar panels in winter is to pair them with a solar battery system. While daylight hours are shorter in winter your solar panels will still generate energy during the day. A solar battery stores any excess energy your system generates so you can use it later – such as in the evening when the sun has gone down.

This is a great way to reduce your grid reliance and get the most out of your solar PV system all year round. By storing energy during the day, you’ll ensure your home is powered by renewable energy even when the sun isn’t shining.

Winter is a Great Time to Switch to Solar!

If you’ve been thinking of switching to solar energy then don’t wait for summer! Solar panels in winter have many benefits – better efficiency in cooler temperatures, more availability for installation and you’ll be ready to generate maximum energy come spring and summer.

Winter may seem like an odd time to install solar panels but it’s actually one of the best times to make a long-term investment in your home. Get ahead of rising energy prices, take advantage of government incentives and start saving on your bills now.
