Many homeowners assume solar panels can only be installed on the main roof of their home. However, that’s not always the case. If you’re wondering whether solar panels on garage roofs are possible, the answer is often yes.
In fact, many properties benefit from installing solar panels across both the house and the garage. This approach can maximise the available roof space, increase the amount of electricity your system generates and help prepare your home for future technologies such as battery storage, EV chargers and air source heat pumps.
Every property is different, which is why a professional survey is the best way to determine the most suitable system for your home.
Can Solar Panels Go on My House and Garage?
Yes. Many homeowners choose to install solar panels on both roofs rather than limiting the system to the main house.
If your garage has good sun exposure and a suitable roof structure, it can provide valuable additional space for more panels.
Using both roofs often allows a larger solar system to be installed, helping generate more renewable electricity throughout the year.
Rather than viewing the garage as a separate building, it can become an important part of your overall renewable energy system.

What If My House Roof Is Already Full?
One of the biggest advantages of having a garage is the additional roof space it provides.
If your house roof has already reached its capacity, you may still be able to expand your system by installing additional solar panels on your garage roof.
This can be particularly useful if your electricity usage has increased over time.
For example, you may have:
- Purchased an electric vehicle.
- Added battery storage.
- Installed an air source heat pump.
- Started working from home.
- Increased your household electricity usage.
Instead of replacing your existing solar system, your installer may be able to design an extension using the garage roof.
Looking to Make the Most of Your Roof Space?
Whether you’re considering solar panels on your house, garage or both, we can design a system that suits your property and your future energy plans.
Does the Garage Roof Need to Face South?
No.
Although south facing roofs generally produce the highest annual generation, east and west facing roofs also perform very well.
In some cases, a garage roof may receive better sunlight than the main house.
Modern high efficiency solar panels allow installers to design systems across multiple roof areas to maximise overall performance.
A professional survey will determine the most effective panel layout for your property.
Is My Garage Roof Suitable?
Most garages can be assessed in exactly the same way as the main house.
During a survey, your installer will consider:
- Roof condition.
- Roof construction.
- Available roof space.
- Roof orientation.
- Shading.
- Cable routes.
If the garage roof is suitable, it can become a valuable addition to your solar installation.
Can I Add Battery Storage Too?
Absolutely.
Many homeowners combine solar panels with battery storage to make better use of the electricity they generate.
During the day, any surplus electricity can be stored in a battery instead of being exported immediately to the grid.
The stored energy can then be used later in the evening when electricity demand is often higher.
Whether your panels are installed on the house, the garage or both, battery storage can become an important part of your renewable energy system.

Can Solar Panels Support an Air Source Heat Pump?
Yes.
Air source heat pumps use electricity to heat your home and hot water.
Although solar panels won’t supply all of the electricity required throughout the year, they can help support the electrical demand of an air source heat pump during daylight hours.
Many homeowners now plan their renewable energy upgrades together by combining:
- Solar panels.
- Battery storage.
- EV chargers.
- Air source heat pumps.
Designing these technologies together helps ensure they work efficiently now while allowing room for future expansion.

Planning for an EV Charger?
If you’re thinking about buying an electric vehicle, it’s worth considering this during the design stage.
A larger solar system spread across the house and garage may generate more electricity to support your home’s overall energy usage.
Many homeowners also choose to install an EV charger alongside their solar system or add one later.
Planning ahead makes future upgrades much simpler.

Future Proof Your Home
A professionally designed solar system doesn’t just meet your needs today. It also considers future technologies such as battery storage, EV chargers and air source heat pumps.
Why Use Both the House and Garage?
You don’t always have to choose one roof or the other.
Many of the most effective solar installations use both the house roof and the garage roof to maximise generation.
Using all of the available roof space may allow you to install additional panels, generate more renewable electricity and prepare your home for increasing energy demands in the future.
A professional survey will determine the best layout based on your roof orientation, shading, electricity usage and future plans.

Can Solar Panels Be Installed on a Garage and House?
For many homes, the answer is yes.
Garage roofs often provide valuable additional space for solar panels, especially if the main house roof has already reached its capacity.
Whether you’re installing your first solar system or looking to expand an existing one, using both the house and garage roof could help maximise generation and prepare your home for battery storage, EV charging and air source heat pumps in the future.
