Solar Panel Building Approval in Tasmania: What to Check

Solar installations involve building work and electrical work, and some properties also need planning approval. The correct pathway depends on the building class, panel area, roof layout, mounting method and structural details—not simply the system’s kilowatt rating.

The current CBOS regulatory guide for solar panels is the authoritative starting point. If the category is unclear, confirm it with a building surveyor or your local council before work begins.

When Can Rooftop Solar Be Low-Risk Work?

For houses and sheds (Class 1 and 10 buildings), CBOS lists a roof-mounted installation as low-risk only when all relevant criteria are met:

• The mounting system is a proprietary product or pre-engineered solution.

• Panels are parallel to the roof rather than tilted above it.

• The solar-panel array covers no more than 38 m².

• The array adds no more than 100 kg of dead load at any single attachment point.

• There is no more than 100 mm between the roof surface and the underside of the panels.

• Panels remain at least 200 mm from the edge of the roof plane.

The 38 m² figure is only one condition. A design can fall outside the low-risk category even when its panel area is smaller. Conversely, system capacity in kW does not by itself determine whether approval is required. Commercial buildings and ground-mounted systems have different criteria.

Planning, Building, Electrical and Network Checks Are Separate

These requirements are related but not interchangeable:

• Planning: Your local council can advise whether the property, heritage controls or planning scheme require approval.

• Building: The work must be classified as low-risk, notifiable or permit work under Tasmanian requirements.

• Electrical: Electrical work must be completed by a licensed electrician.

• Network connection: Grid-connected systems need the required connection approval from TasNetworks, or Hydro Tasmania on the Bass Strait Islands.

CBOS also warns that work completed without required approvals can attract penalties. A council may allow retrospective approval, but it may also require an installation to be removed. See CBOS guidance for homeowners for the current overview.

Who May Need to Be Involved?

Depending on the design and work category, the process may involve the solar designer, licensed electrician, building surveyor, structural engineer and council permit authority. An engineer or building surveyor is not automatically required for every installation, so the quote should state which checks apply to the specific property and who is responsible for each one.

What Does Approval Cost?

There is no reliable flat price for Tasmania. Fees can vary by council, surveyor, engineering work, building class and project complexity. Treat a generic online figure as an estimate only. Before accepting a proposal, ask for the expected approval pathway and all known third-party fees in writing.

Questions to Ask Before Signing

• Which building-work category applies to this design, and why?

• Does the layout meet every low-risk criterion—not only the 38 m² limit?

• Who will obtain any planning, building, electrical and network approvals?

• Are surveyor, engineering and council costs included in the proposal?

• What approval and compliance documents will I receive after installation?

How Solvitec Approaches the Process

Solvitec reviews the property, proposed layout and system requirements before installation. We explain the expected approval pathway, identify who is responsible for each step and discuss known third-party costs before work proceeds. If specialist advice is required, we coordinate the relevant parties rather than treating approval as an afterthought.
