Or try it on the web →This solar installation quote template is for residential jobs up to 10kW. It's built for Aussie solar installers quoting standard grid-connect systems. Most quotes go wrong in two places: under-pricing the labour on a steep or tricky roof, and miscalculating the STC rebate value on the day. Get those right, and you protect your margin. This template helps you list every component, from the panels down to the DC isolators, so you can price accurately and show the customer exactly what they're paying for before the rebate is applied.
Pricing Labour and Hardware for a Standard 6.6kW System
A standard 6.6kW system has a pre-rebate base cost of around $5,500 to $8,000. This covers hardware and labour before your margin. Labour for two installers for a full day on a single-storey tin roof will be about $1,200 to $1,800. The hardware adds up: 16 x 415W panels from a supplier like One Stop Warehouse will be about $2,800. A 5kW Sungrow or Fronius string inverter adds another $1,200. Mounting gear from Clenergy might be $600. Add another $400 for cabling, conduit, and breakers from a wholesaler like TLE. The total pre-margin cost sits at a minimum of $6,200.
What Gets Left Off a Solar Quote: Access, Safety, and Switchboards
The items that kill your profit are scaffold hire and switchboard upgrades. A steep tile roof (over 22 degrees) or any two-storey job requires edge protection under safety rules, adding $600 to $1,500 to your costs. If the customer's house has an old ceramic fuse board, it needs a full upgrade to comply with AS/NZS 3000, which can be another $1,000 to $2,000 surprise. Using a quoting app like QuoteMate lets you create saved line items for these extras so you can add them instantly. Always check the switchboard during the site visit. All solar work must follow AS/NZS 5033.

Frequently Asked Questions
Calculate STCs based on system size, location (zone), and the current year's deeming period. A 6.6kW system in Melbourne (Zone 4) creates fewer STCs than one in Brisbane (Zone 3). The STC price changes daily. Check a live trading site like Formbay for today's price, which usually sits between $38 and $40 per certificate.
Quote microinverters for roofs with partial shading from trees or chimneys, or for customers wanting panel-level monitoring. They add around $2,000 to a 6.6kW system compared to a string inverter. For a simple, unshaded north-facing roof, a quality string inverter from a brand like Sungrow, sourced via a wholesaler like Middy's, is the most cost-effective option.
For battery storage, you must quote a hybrid inverter, not a standard solar inverter. A hybrid inverter like a Fronius Gen24 costs about $1,000 more than its solar-only equivalent. The battery itself, like a 10kWh Sungrow SBR, will add at least $7,000-$9,000 to the total quote, plus extra labour for installation and commissioning.
