Conclusion - are renewables effective throughout winter?
Heat Pumps – With the ability to extract heat from the air in temperatures of -25°C, these systems are more than capable of dealing with the relatively mild winters that the UK experiences. Far from leaving your home to freeze, you home might be a few degrees colder than the summer temperatures, but you’ll never have to ‘wait for the heating to come on’ because it’ll never turn off!
With the highest rate of usage in Europe, Sweden leads the way in ground source heat pump installations. For these to have excelled in such an environment shows the durability of these systems in extreme temperatures. The expertise and innovation of heat pumps in Sweden is another reason why we’re proud to only fit Swedish based Nibe’s heat pumps for our customers.
Solar Power – Solar panels are inherently limited by the hours of daylight received daily, meaning that they are always going to be affected by the reduced hours of light over winter. Despite this, they’re still able to provide energy throughout winter but the feasibility of relying purely on this system will depend on the overall capacity of the solar panels you’ve installed. If your panels are only just meeting your summer energy requirements, then they would be insufficient during the darkest winter months. However, this can be avoided if you’re producing a surplus of energy over the summer months – a feature that can still be profitable if the excess is being sold back to the grid. Despite the government ending their feed-in tariff scheme, the smart export guarantee was launched on the 1st of January 2020 and means that suppliers such as Octopus are still offering payment for excess energy supplied to the grid.
