Design + roof-stage
Plan-based design
We design from your plan set and lock the package before roof-on. No day-of scope surprise for the site super.
For Logan builders
Solar for Logan builders. Trade-direct, single-visit install.
Yarrabilba, Flagstone, Greenbank — Trade Solar covers every active growth corridor in Logan. BAL-rated mounting and Energex grid handling included by default. Coordinated to your roof-on date.
Why Logan
High solar yield. Compliance heat. Buyer expectation.
Logan is the highest-volume detached-house LGA in SE QLD, with Yarrabilba, Flagstone, and Greenbank driving most of the activity. NCC climate zone 2 delivers strong solar yield (~5.2 kWh/m² daily). Buyer demographics here are price-sensitive but expect solar as a baseline inclusion in mid-spec project homes — making it a fast-conversion margin line for builders running release programs in the southern corridor.

Logan-specific
What changes on the day.
-
Logan growth-corridor volume
Logan City Council currently approves the largest detached-house volume of any SE QLD LGA. Yarrabilba, Flagstone, and Greenbank are the three biggest greenfield estates and are central to most volume builders' release programs.
-
BAL overlay handling
Logan estates near rural-residential boundaries (Greenbank, Jimboomba, parts of Flagstone) carry BAL-12.5 and BAL-19 ratings. Trade Solar uses BAL-rated cable shrouding and IP-rated isolators automatically — no upcharge.
-
Energex grid connection
Logan connections route through Energex same as Brisbane. Approval typically 5–10 business days from install. We lodge the application on your behalf at install.
-
Roof aspect on Logan estates
Many Logan estates use east-west street grids that constrain north-facing roof area. We design split-array systems to help the Whole-of-Home energy budget even with non-ideal aspect.
Trust

-
Behind the builder

FAQ
Builder questions, answered.
Do you sell solar direct to our buyers?
No. Trade Solar is trade-only. We sit behind your brand on the selections sheet. If a homeowner finds us, we send them back to their builder.
When does the crew come, and how long are they on site?
We lock one install slot to roof-on (and final-fit as programmed). The crew aims for a single visit for fit and commission, with SMS to the site super beforehand. Weekdays only, 7am–5pm Brisbane time.
Who handles STCs, Energex/Ergon, and warranty after handover?
We lodge the compliance pack (including STC paperwork) and connection requirements for Energex on Logan. After handover, the homeowner contacts Trade Solar for warranty and support, not your office.
