Solar sits on top of electrical work, so the price drivers are a mix of panel and inverter spec and the switchboard reality behind the meterbox — a 6.6kW string job is a different quote to a 13kW three-phase system or an EV charger run across the house. STC rebates, roof complexity and battery compatibility all move the final number, and none of it is obvious to the homeowner. Tradewin prices any solar or battery job against your real costs and sends a professional quote from the roof. Save your standard systems — 6.6kW installs, battery add-ons, EV charger fits — as TradeWin Recipes™ so the next quote is a two-tap job.

The same job can vary widely. Tradewin prices against your real costs, so these factors are built in — not guessed.
Panel count and inverter spec set the base, and stepping up to a 13kW or three-phase system often forces a switchboard upgrade the customer never budgeted for.
Tile versus tin, pitch, storey height and the number of strings all change install time — the same kW system can price very differently across two roofs.
Adding storage to existing solar depends on inverter compatibility, AC versus DC coupling and cable runs, which is why battery add-ons vary so widely job to job.
Panel and battery prices move, and the STC value nets off the customer price. Quoting off current costs and rebate levels keeps the system profitable.
10kW Solar System
Varies with panel count, inverter, and any required switchboard upgrades.
13kW Solar System
Larger systems often require a 3-phase inverter or switchboard upgrade.
6.6kW Solar System
Varies with panel brand, inverter spec, roof complexity, and number of strings.
Battery Add-On (Existing Solar)
Compatibility checks, inverter upgrades, and cabling runs cause wide price variation.
Battery Storage — ~10kWh
Battery chemistry, brand, and compatibility with existing inverter affect pricing significantly.
Battery Storage — ~15kWh
Varies with brand, AC vs DC coupling, and switchboard requirements.

Yes. Tradewin supports 13+ solar & energy job types including 10kW Solar System, 13kW Solar System, 6.6kW Solar System. You can also add custom job types for work that isn't in the list.
Most tradies price and send a quote in under two minutes once costs are saved. Repeat jobs are faster — apply a TradeWin Recipe and the costs scale to the new job size automatically.
The website quote form works on the free plan and every paid plan. A dedicated inbound number is included with Business and Scale, or available through the separate number add-on on other plans. Either way, a saved Recipe can prepare a priced draft for you to review and send.
Yes. Once you issue an invoice you can push it straight to Xero as a draft — no double data entry.
Yes — you price the job against your real hardware and labour costs, then net off the STC value so the customer sees the true out-of-pocket figure. Because solar overlaps electrical, switchboard upgrades and compliance time can be built into the same quote.
It can. Battery storage, battery add-ons to existing solar, and EV charger installs are separate pre-loaded job types, so you can price a retrofit on its own or bundle it with a new system.
