As autumn arrives, you might wonder whether it is worth getting solar panels before winter, or whether you should wait until spring. After all, the days are getting shorter, the weather is changing and solar generation will naturally be lower during the winter months.
However, solar panels are a long term home energy investment. Therefore, it makes more sense to look at expected generation across the whole year rather than judging a solar PV system by its winter performance alone.
Installing solar panels during autumn can also mean your system is already generating electricity before spring and summer arrive. So, if you are considering solar panels in Blackpool, Poulton le Fylde, Thornton Cleveleys, Lytham St Annes or elsewhere across Lancashire, there is no need to automatically wait for warmer weather.
Do Solar Panels Work in Winter?
Yes. Solar panels can still generate electricity during winter.
Solar PV panels convert light into electricity. They do not require hot weather to operate. However, the amount of electricity a system generates depends on several factors, including available solar irradiance, the size and orientation of the system, shading and local conditions.
As a result, shorter winter days generally mean lower generation compared with spring and summer.
That does not mean your solar panels stop working.
For example, even on a cold but bright winter day, a solar PV system can generate electricity for your home. Generation will simply vary throughout the day and across the seasons.
Is It Worth Getting Solar Panels Before Winter?
If you are already planning to install solar PV, autumn can still be a suitable time to go ahead.
Waiting until spring does not necessarily provide an advantage. In fact, installing solar panels before winter means your system can begin generating as soon as it has been commissioned.
More importantly, it will already be installed when daylight hours begin increasing again.
Solar should usually be considered over a much longer period than a single season. When we design a system, we look at factors such as the property, roof, household electricity consumption and expected annual generation.
Therefore, winter performance is only one part of the overall picture.
Solar Panels Generate Electricity From Light, Not Heat
One of the most common misconceptions about solar PV is that panels need hot weather.
They do not.
Solar photovoltaic panels use solar radiation to produce electricity. Consequently, a sunny summer day will often provide strong generation because there are more daylight hours and typically greater solar irradiance. However, it is the available light rather than outdoor temperature that enables generation.
This is an important distinction when considering solar panels in the UK.
Naturally, the shorter days during December and January reduce the amount of time available for generation. Nevertheless, your system can continue producing electricity whenever conditions allow.
Why Annual Solar Generation Matters More
When considering solar, it can be tempting to look at what a system might generate today. However, that only provides a snapshot.
A properly designed solar PV system should come with an estimate of its expected annual generation.
This allows you to understand how the system could perform across different seasons rather than concentrating solely on the winter months.
At West Coast Electrical & Renewables, we design systems around the individual property. Roof orientation, available space, shading and household energy requirements can all affect the final design.
Therefore, two neighbouring homes do not necessarily need exactly the same solar system.
Thinking About Solar Before Winter?
We can assess your property and design a solar PV and battery storage system around your home and electricity usage.
What Happens to Solar Generation During Winter?
You should expect your solar generation to change throughout the year.
Generally, spring and summer provide longer daylight hours. As a result, these months often account for a larger proportion of annual solar generation.
During autumn and winter, generation falls as the days become shorter.
However, your household will continue using electricity throughout these months. Any solar electricity generated and used within the property can reduce the amount of electricity you need to import from the grid at that particular time.
How much you use directly will depend on when your system generates electricity and when your household consumes it.
This is where battery storage can become particularly useful.
Should I Add Battery Storage to Solar Panels?
You do not have to install battery storage with solar panels. However, many homeowners choose to combine the two technologies.
A battery can store electricity for use at another time, subject to the system configuration, battery capacity and available stored energy.
Furthermore, some battery systems can use electricity imported from the grid during selected periods. This can be useful for households on compatible time-of-use electricity tariffs.
For example, a battery may be configured to charge during a cheaper overnight tariff and then provide stored electricity during more expensive periods.
However, electricity tariffs, import rates and export rates vary considerably between providers. Therefore, we would always recommend checking the current terms of your tariff rather than assuming a particular charging strategy will provide the best financial outcome.
Solar Panels Before Winter and Battery Storage
Combining solar and battery storage gives homeowners more options for managing their electricity.
During periods of stronger solar generation, surplus electricity may be stored in the battery rather than immediately exported, depending on how the system has been configured.
Alternatively, exporting surplus electricity can sometimes make more financial sense depending on your export tariff.
For this reason, there is no single setup that works best for every household.
Your electricity consumption, solar generation, battery capacity and tariff all need to be considered together.
Modern monitoring platforms can also help you see how electricity moves around your home. Depending on the equipment installed, you may be able to view solar generation, household consumption, battery charge and grid imports or exports through an app.
Can Solar Panels Support Other Renewable Technologies?
Solar PV can form part of a wider home energy system.
For example, homeowners may also have battery storage, an EV charger or an air source heat pump.
Each technology increases or changes the way electricity is used within the property. Therefore, considering future plans at the design stage can be worthwhile.
If you expect to purchase an electric vehicle, add battery storage or install an air source heat pump later, tell your installer during the initial solar survey.
This does not necessarily mean you need a larger solar system. Instead, it allows the installer to consider your current and potential future electrical requirements when designing the installation.
Can Solar Panels Be Installed During Autumn and Winter?
Solar installations take place throughout the year.
However, weather conditions always need to be considered. Safe working practices come first, particularly when installers are working at height.
Severe weather may occasionally mean an installation needs to be rearranged. Nevertheless, autumn itself does not prevent a solar PV system from being installed.
At West Coast Electrical & Renewables, our team assesses each installation individually. This includes the electrical installation as well as the roof, mounting requirements and proposed equipment.
Choosing an MCS Certified Solar Installer
If you are considering solar panels before winter, choosing the right installer is an important part of the process.
West Coast Electrical & Renewables is MCS certified for solar PV and battery storage. We are also RECC accredited and provide renewable energy installations alongside our wider electrical services.
We install solar PV and battery storage across Blackpool, Poulton le Fylde, Thornton Cleveleys, Lytham St Annes, Preston and surrounding areas of Lancashire.
Most importantly, we design the system around the individual property rather than using the same specification for every home.
Should You Wait Until Spring to Install Solar Panels?
There is no requirement to wait until spring.
Although your solar panels will generally produce less electricity during the darker winter months, installing now means the system can begin generating straight away. It will also already be operational as daylight hours increase through spring.
Therefore, if you are already considering solar PV, autumn can be a practical time to start planning your installation.
The important part is getting the right system for your property.
A good solar design should consider expected annual generation, your electricity consumption, roof space, orientation, shading and whether technologies such as battery storage may also suit your requirements.
