Winter will be here before we know it, and many people are questioning the effectiveness of solar panels during colder months. They fear the drop in solar power output during winter and while there is a slight drop, it’s not for the reasons you might think. The most common reasons are due to more cloud cover, shorter days and the angle of the sun. But, don’t dismay, because there is plenty you can do to ensure that your PV panels generate efficient energy all through winter.
Winter doesn’t always mean less solar power. In fact, solar panels are tested at 25 degrees Celsius and will reduce output efficiency for every degree above that. This means that your solar panels will perform much better in cooler, sunny weather than during summer. And since South African winters are mild compared to other countries and we have plenty of sunshine during the day, your solar panels will work just fine.
How to Increase Solar Panel Efficiency
If you haven’t done it recently, give them a good clean to get rid of dirt or grime buildup. Avoid using rough brushes and harsh chemicals to clean panels and use a soft cloth or sponge with warm water instead. If you can’t reach your PV panels easily, get in touch with your installer for routine maintenance and cleaning.
Make sure your panels are still getting sufficient sunlight. Your PV panels typically receive full sun from around 9 am to 5 pm. But, with the angle of the sun differing from summer to winter, it would be wise to trim any overgrown trees or stray branches that might be in the way of your precious sunlight.
It’s no secret, solar is the way forward! And if you’re worried that your solar panels won’t be as effective in winter as in summer, don’t be! For more information or a free quote, speak to the team at Nupower today!
