If you’re considering solar panels for your home, your main roof isn’t your only option. Many homeowners across Essex, Kent, Suffolk, Hertfordshire and the wider South East and East Anglia are discovering that garages, sheds and other outbuildings can provide an excellent location for solar panel installation.
Whether your home roof isn’t suitable due to shading, orientation or planning restrictions, or you’re simply looking to maximise your available space, installing solar panels on alternative structures could be the ideal solution.
At SolarTherm UK, we’ve spent over 16 years designing and installing bespoke solar PV systems across the region, helping homeowners make the most of every available roof space while ensuring installations remain safe, efficient and fully compliant with UK regulations.
Can Solar Panels Be Installed on Garages, Sheds and Outbuildings?
Absolutely, as long as the building is structurally sound and receives sufficient sunlight throughout the day, garages, sheds, workshops, garden rooms, barns and other outbuildings can all support a solar PV system.
In many cases these structures actually provide better installation opportunities than the main house because they may offer:
- Better south-facing roof orientation
- Less shading from neighbouring buildings
- Easier cable routing to batteries or consumer units
- Simpler installation access
- Greater flexibility for future expansion
Many homeowners are surprised to learn that an unused garage roof can generate a significant proportion of their household electricity.
Why Install Solar Panels on a Garage?
Garages are among the most popular alternative installation locations. Whether attached or detached, garages often provide ideal roof angles while keeping the main house visually unchanged.
Benefits include:
- Maximising otherwise unused roof space
- Keeping the main property’s appearance intact
- Powering EV chargers located inside garages
- Supporting battery storage systems installed nearby
- Potentially reducing cable runs for electric vehicle charging
Garage roofs can accommodate both traditional on-roof systems and integrated solar panels where roof replacement is planned.
Are Shed Roofs Suitable for Solar Panels?
Many modern sheds and workshops are perfectly capable of supporting a small solar PV array. This can be particularly useful if you:
- Work from a home office or garden room
- Charge garden equipment
- Power lighting and security systems
- Run workshop machinery
- Charge electric bikes
Large timber buildings can also provide excellent locations for battery storage equipment when designed with adequate ventilation. Before installation, SolarTherm UK’s surveyors assess structural integrity, roof condition and loading capacity to ensure the building is suitable.
Flat Roof Solar Panels for Garages and Outbuildings
Many garages feature flat roofs, leading homeowners to wonder whether solar is possible. The answer is yes. Modern flat roof solar panels are installed using specially engineered mounting systems that position the panels at the optimum angle for maximum energy production.
Benefits include:
- Excellent performance
- Flexible orientation
- Minimal roof penetration
- Reduced visual impact
- Easy maintenance access
Ballasted mounting systems are commonly used where appropriate, helping protect roof membranes while maintaining structural integrity. Every installation is designed individually based on roof construction, wind loading, building height, local weather exposure and structural calculations.
Structural Considerations
Every installation begins with a professional structural assessment. Our experienced surveyors evaluate:
- Roof age
- Timber condition
- Roof coverings
- Load bearing capacity
- Wind exposure
- Existing damage
- Waterproofing
Installing solar onto a weak roof can cause problems later, so ensuring structural suitability is an essential part of every SolarTherm UK project.
Electrical Connections
Outbuilding installations require careful electrical design. DNO requirements, export limitations, cable sizing and routes, voltage drop, earthing arrangements and distance to the consumer unit are all factors that need to be considered. Our qualified installers design each system to maximise efficiency while remaining fully compliant with current electrical regulations.
Battery Storage for Outbuilding Installations
Many homeowners choose to install battery storage alongside garage or outbuilding solar. This offers several advantages:
- Greater self-consumption
- Backup power capability
- Lower evening electricity bills
- Better use of exported energy
- Reduced reliance on the National Grid
Battery systems can often be located inside garages where environmental conditions are suitable.
Planning Permission
In many cases, solar panels installed on garages, sheds and outbuildings fall under Permitted Development Rights. However, additional permissions may be required for listed buildings or properties within a conservation area.
SolarTherm UK can advise homeowners throughout Essex, Kent, Suffolk, Hertfordshire and the surrounding areas on the planning considerations that may apply to their property before installation begins.

Frequently Asked Questions
Yes. Provided the roof is structurally suitable and receives enough sunlight, garage roofs are often excellent locations for solar panel installation.
Yes. Modern mounting systems angle the panels correctly, allowing flat roof solar panels to generate excellent levels of electricity.
The terms are often used interchangeably. Both replace sections of the roof covering to create a flush, attractive finish rather than sitting above existing tiles.
They can be. As ground mounted solar panels can often be positioned at the ideal angle and orientation, they may achieve excellent generation where roof space is limited or poorly orientated.
Yes. Many sheds, workshops and garden buildings are suitable, provided they are structurally sound and capable of supporting the system safely.
