Solar Panels for Sheds, Garages and Outbuildings: What's Practical?

Quick answer: Yes, solar panels can go on a shed, garage or other outbuilding if the roof is solid, mostly unshaded and faces roughly north, and a licensed electrician can connect it to your switchboard. Most owners add these panels to their main system instead of building a separate one.

Is a shed roof a good place for solar panels?

Sometimes it beats the house roof. A detached garage with a clear north-facing roof has no skylights, vents or chimneys to work around, which leaves room for a tidy array. A workshop, studio or double garage usually makes a better host than a small garden shed, because panels need solid fixing points and a small roof offers few of them.

When you weigh up solar panels for a shed, the size, age and condition of the building matter as much as which way the roof faces. If trees or the house shade the roof for part of the day, read our solar panel shading guide first.

What does the structure need to handle?

Panels add weight and wind load to a building that was never designed around them. Follow the mounting manufacturer's engineering certification, including foot spacing, fixing type and clamping zones, and meet the wind requirements.

On a shed, that means fixing into the frame, not only the roof sheeting. Ask your installer to confirm the frame can carry solar panels on the shed roof, and bring in an engineer if the structure is light or old. Our roof types guide and roof weight and warranty guide cover mounting and load in more detail.

How does the power reach your home?

Through a cable run to your switchboard, installed by a licensed electrician. If the outbuilding shares your property's supply, shed-roof panels can feed the same system as any house panels, so they power the whole property, not only the shed.

Cable distance changes the quote, so ask for it to be itemised, and keep the electrical compliance certificate your electrician issues when the work is finished. Your electricity distributor must also approve the system before it is switched on.

Do you still get the STC discount?

Yes, if the system meets the normal rules. The Clean Energy Regulator requires Clean Energy Council (CEC) approved panels and inverters, a Solar Accreditation Australia (SAA) accredited designer and installer, compliance with Australian standards, and STCs created within 12 months of installation.

STCs are assigned to a property address, and the regulator notes that systems on transportable buildings may be eligible if they meet every requirement. Our STC rebate guide explains how the discount works.

Do you need council approval?

It depends on your state and council. In NSW, City of Newcastle explains that some solar panels are exempt development under the Transport and Infrastructure SEPP if they meet set conditions, while others need a complying development certificate or a development application. Other states have their own rules. Check with your council or certifier before booking, and confirm the shed itself is approved.

Grid-connected or standalone?

Grid-connected is the practical choice for a building that already has mains power, and a battery can be added later. If you already have panels on the house, the shed roof can sometimes take extra capacity rather than a second system, which your installer can assess.

A standalone system suits a remote shed where bringing in mains power would cost too much, but it needs its own design by an SAA-accredited stand-alone power system installer. Our grid, off-grid and hybrid guide compares the options.

Shed solar checklist

  • The roof faces roughly north and is shaded for little of the day.
  • The frame and fixings can carry the array under local wind conditions.
  • A licensed electrician has quoted the cable run.
  • You have checked planning rules with your council.
  • Your installer holds current SAA accreditation and uses CEC-approved products.
