Choosing to install solar panels is a long-term calculation. Good quality panels will provide electricity for 30 years or more, paying for themselves several times over. It is true you should expect less output in the short dark days of winter, but there are no compelling reasons for waiting until spring to install them. In fact, there is no time like the present.

Why autumn and winter are good times to install solar panels

The first reason is that most other people don’t, so it is easier to book the installation for the date you want and get the undivided attention of the engineers.

The second is that it makes little sense to forget about home improvements as soon as the nights turn chilly. With the approach of the coldest and wettest months we should be giving more thought to our energy efficiency, not less. If you are installing solar panels on a roof, it is also possible to combine it with a roof inspection and have any weak spots sorted at the same time, before the snows arrive and find them for us.

How well do solar panels work in winter?

Cold weather is not a problem for photovoltaic solar panels. In fact, they are more efficient at lower temperatures and their pitch is usually enough for snow to slide straight off.

Short dull days are a bigger problem, but even in the dead of winter on a reasonably clear day you can expect up to half the energy output you will get in summer. The orientation of your panels will make a lot of difference. Roofs facing south with a clear view toward both horizons will be less affected, while those surrounded by tall buildings will be impacted more. Some installations let you adjust their angle to catch more low sun.

Make sure you install enough good quality panels and you will be warm all year round without worrying about the fuel bill.
