Solar is cheaper when it goes on during the build
Installing solar during construction costs less than retrofitting it later. The scaffolding is already up, the roof is clear and unobstructed, cable runs happen before wall linings go on, and the switchboard can be specified correctly from the start. If you are building, this is the cheapest solar will ever be for your home.
Why build-time is cheaper
- Scaffolding is already there. On a retrofit, scaffolding is a real line item. On a new build it is already up and paid for.
- Clear roof access. No working around a finished, occupied home. Faster, safer, cheaper.
- Cabling before linings. Cable runs go through open framing rather than being fished through finished walls or run in surface conduit. Neater result, less labour.
- Correct switchboard from the start. Specify it once rather than upgrading later.
- One disruption, not two. The house is a building site already.
If you are building
Talk to us before the roof goes on, ideally at design stage. Roof pitch, orientation and penetrations are all easier to get right before they are built. We can work alongside your builder and electrician.
If you are a builder or developer
We work with group builders and developers on standard packages across multiple homes. Consistent specification, predictable install windows, and a genuine differentiator on your build offering as buyers increasingly ask about running costs.
Talk to us about a standing arrangement.
If you have just moved into a new build
New builds are our cheapest and fastest retrofit installs. Simple pitches, no mature-tree shading, modern switchboards, no asbestos, no surprises. Usually done in a day.
