Perth quote factors
What to factor into your Perth solar installer quote
Local context that should shape what you quote as a solar installer in Perth. Mediterranean. Hot dry summers (Dec-Feb, frequent 35°C+, 40°C+ events), mild winters (June-Aug, rarely below 5°C), most rainfall in winter (~750mm/year). Fremantle Doctor afternoon sea breeze cools coast. Extreme UV year-round. Bushfire risk in Perth Hills (BAL ratings mandatory in hills suburbs).
CEC accreditation mandatory for STC
Clean Energy Council (CEC) accreditation is mandatory for STC (Small-scale Technology Certificate) eligibility under the Federal Renewable Energy Target. Building and Energy WA electrical licence required for electrical connection. Print CEC accreditation number, electrical licence number, ABN and GST status on every quote and invoice. AS/NZS 5033 (PV array) and AS/NZS 4777 (grid connection) compliance mandatory.
Per-kW installed cost
Perth residential 6.6kW system runs A$2,480-A$4,280 fully installed including GST and STC rebate netted at point of sale. Per-kW: A$375-A$650. Premium tier (Cottesloe, Dalkeith, Peppermint Grove) with Tier 1 panels (REC Alpha Pure, SunPower Maxeon, LG NeON, Q Cells), microinverters (Enphase IQ8) and battery storage at A$520-A$835 per kW.
Synergy DEBS lower buyback than east coast
WA replaced the old REBS feed-in tariff with the Synergy Distributed Energy Buyback Scheme (DEBS), paying a lower export rate than east-coast states (peak vs off-peak buyback windows). Size systems for self-consumption first, export second. State the current DEBS peak and off-peak rates and battery payback explicitly on the quote; conversion rate doubles when DEBS economics are visible.
STC rebate netted at point of sale
Federal STC rebate (Small-scale Technology Certificate) currently delivers roughly A$900-A$1,580 off a 6.6kW system at point of sale (assigned to retailer in exchange for upfront discount). State the STC number, deeming period (currently to 2030, reducing annually), and net price clearly on every quote. Customers compare net price; lead with net.
Battery storage growth + Synergy economics
Perth battery storage growing fast thanks to Synergy DEBS lower export rate (self-consumption beats export economically) and grid resilience. Quote battery storage (Tesla Powerwall 3, Sungrow SBR, BYD HVM, sonnenBatterie) at A$4,500-A$8,100 per battery installed. Multi-battery systems common in Cottesloe and Dalkeith at A$9,900-A$24,750. State payback period (currently 7-12 years with Synergy DEBS) on every quote.
Western Power coordination + STC paperwork
Western Power is the state-owned DNO for most of Perth metro. Quote Western Power application and approval as a separate line; typical lead time 4-10 weeks. STC paperwork and assignment must be lodged within 12 months of install. Print Western Power application reference on the contract.

Yes, growing market thanks to Synergy DEBS lower export rate. Perth battery storage grows fast because self-consumption beats export economically. Quote Tesla Powerwall 3, Sungrow SBR, BYD HVM, sonnenBatterie at A$4,500-A$8,100 per battery installed. Multi-battery systems common in Cottesloe and Dalkeith at A$9,900-A$24,750. State payback period (currently 7-12 years with Synergy DEBS) on every quote.
Per kW installed in {YEAR}: $540 to $1,130 in the US, £1,200-2,000 in the UK, A$405-1,800 in Australia, R18,000-35,000 in South Africa, and C$1,080-3,800 in Canada. Larger systems get cheaper per-kW due to scale; tier-1 panels and premium inverters push toward the top.
Most 3-bed homes need 5-8kW; 4-bed+ homes with pool or EV need 8-12kW. Look at your last 12 months of electricity bills, divide annual kWh by 1,300 (Australia/SA), 950 (UK/Canada), or 1,200 (US average). That gives kW capacity to offset most of your bill.
Depends on your feed-in tariff. Where FIT is high (Australia historically), batteries have 10-12 year payback; export to grid is more valuable. Where blackouts are common (South Africa) or FIT is low (UK), batteries pay back faster and add resilience. Quote both options.
A standard 5-10kW residential install is 1-2 days on the roof for a 3-person team, plus grid connection paperwork (1-6 weeks depending on utility). Larger systems and commercial installs take 3-7 days.
Site visits and verbal quotes for systems over 4kW are usually free. A detailed shading analysis, structural roof report, and load-flow calc for a 20kW+ commercial system takes 4-8 hours and may be charged $135-1,500. Worth it on large projects.
