You’ve decided to invest in solar panels for your home. Great choice. But now you’re wondering about timing.
Should you wait for the summer sunshine? Is winter actually better for booking an installer? What about those unpredictable spring showers?
It’s a common question we hear at Electrical Innovations. While solar panels work effectively year-round in the UK, the timing of your installation can affect everything from how quickly the work gets done to how much you might pay. It can impact installer availability and even how soon you’ll see those savings on your electricity bill start to stack up.
This blog will walk you through the things to consider, to help you choose the right time of year for your solar panel installation.
So, when is the best time of year to get your solar panels installed?
The short answer is… it depends on your priorities and what matters most to you.
Summer usually means better weather for the installation work, but you may have to wait longer to book an installer. In winter, you might be dealing with colder conditions, but it could get your system up and running faster, so you can start saving money.
The good news is that solar panels work effectively year-round in British conditions. Once they’re installed, they’ll generate electricity whether it’s January or July, though obviously with seasonal variations in output.
Rather than focusing on when your panels will produce the most power, it’s worth considering when the installation process itself will be most convenient and cost-effective for you.
Benefits of a summer installation
Summer brings some obvious benefits for getting your solar panels installed. The longer daylight hours mean your installer can work for longer, completing your installation quicker once they begin the work.
The warmer, drier weather also brings more favourable working conditions. There’s less chance of rain, and accessing your roof is generally safer when it’s not wet and slippery.
If you install during summer, you’ll also start generating solar power at the peak production time of the year. Your panels will immediately begin working at their highest capacity, giving you a quick taste of their full potential and maximum savings from day one.
However, it’s worth noting that summer is peak season for solar installations. Many homeowners have the same idea, which means you might face a longer wait and potentially higher prices due to the increased demand.
Benefits of a winter installation
While it might seem counterintuitive, winter can actually be a good time to install solar panels.
Availability is the most significant advantage. Most installers experience lower demand during the winter months, which means you’re likely to face a shorter wait. Instead of waiting months for an installation slot, you might get your system installed within weeks.
Another benefit is that you’ll have your system in place and ready to go when spring arrives. As the days get longer and sunnier, your panels will begin generating more electricity, meaning you’ll be perfectly positioned to capture the full benefit of the spring and summer production peaks.
The main drawback, of course, is the weather. Your installer team may face challenges with rain, wind or even snow, which could potentially delay your installation. The shorter daylight hours also mean less time each day for installation work, potentially extending the process.
Benefits of a spring or autumn installation
The other seasons – spring and autumn – offer a middle ground that many homeowners find appealing.
These seasons typically bring milder weather with moderate temperatures that make working conditions more comfortable for your installation team. While spring can be showery in the UK, it generally presents fewer extreme weather challenges than winter.
Spring installation has the added advantage of getting your system in place ahead of the summer production peak. Installing in April or May means your panels will be generating significant power within weeks of installation.
Autumn installation, meanwhile, gives you plenty of time to optimise your system before the following summer. Any initial adjustments or fine-tuning can be addressed during the winter months, ensuring everything is running perfectly when the next summer arrives.
Other factors to consider
While weather and installer availability are essential considerations, other factors might influence your decision.
Energy prices typically increase (or even decrease) in April and October in the UK when the price cap is reviewed. Installing solar just before these potential increases can maximise your savings from day one.
Manufacturers release new panel designs and more efficient inverters throughout the year. If investing in the latest technology is important to you, it’s worth asking your installer about upcoming releases that might affect your timing.
Government incentives occasionally change, although the UK’s solar landscape has been relatively stable in recent years, with the Smart Export Guarantee scheme. If there are rumours of changing incentives, it might influence your decision.
And if you’re a business owner, installing commercial solar panels near the end of a tax year might offer advantages for your capital allowances or other tax benefits. It’s worth consulting with your accountant about optimal timing.
These factors won’t be decisive for everyone, but they’re worth considering when planning your installation.
Making your decision
Summer’s great if you want optimal conditions and immediate solar generation, and you don’t mind potentially waiting a bit longer for your installation. If you want your system installed quickly and are comfortable with possible delays, winter is your best bet.
Above all, remember that the best solar panels are the ones that are actually installed and generating power. While timing matters, the most important step is getting started on your solar journey.
