Dunedin solar installer pricing
What solar installers should charge in Dunedin
Dunedin solar is constrained on heritage-listed stock (most of central Dunedin, Maori Hill and Roslyn) and concentrated in outer-suburb modern housing (Mosgiel, Brockville, Wakari modern infill, Andersons Bay modern) and detached villa stock with rear or hidden roof slopes (St Clair, St Kilda, Macandrew Bay). SEANZ (Sustainable Energy Association of NZ) membership is the trust signal. EWRB registration is mandatory for the electrical sign-off. Dunedin's southern latitude (45.9 degrees South) means lower solar irradiance than Auckland but still viable; quote conservative output figures.

Dunedin quote factors
What to factor into your Dunedin solar installer quote
Local context that should shape what you quote as a solar installer in Dunedin. Temperate cool maritime (coldest of NZ major cities except Queenstown). Mild summers (Dec-Feb, 18-22°C, rarely above 25°C), cold winters (June-Aug, 4-10°C days, regular overnight frost, occasional snow at sea level), moderate rainfall (~750mm/year, drier than Auckland/Wellington), persistent strong southerly wind. Earthquake risk moderate (Alpine Fault).
Southern latitude solar output
Dunedin's 45.9 degrees South latitude gives lower annual solar irradiance than Auckland (around 1,250 kWh per kW installed per year vs 1,400 kWh in Auckland). Quote conservative output: a 6kW system in Dunedin produces around 7,500 kWh per year vs 8,400 kWh in Auckland. State actual expected output on every quote; over-promising on output is the number one complaint. South-facing roofs are unusable in Dunedin (true south is straight away from the sun in the southern hemisphere).
EWRB, SEANZ and grid-export approval
EWRB registration is mandatory for the electrical sign-off on every solar install. SEANZ (Sustainable Energy Association of NZ) membership is the trust signal premium clients ask for. Grid-export approval through Aurora Energy (Dunedin's lines company) is required before commissioning. Quote SEANZ membership, EWRB practising licence number and Aurora Energy connection fee (NZ$115 to NZ$395) on every quote.
Per-kW pricing tier
Quote 6kW system NZ$4,360 to NZ$7,260 installed (standard pitched-roof Colorsteel or Decramastic). 8kW system NZ$5,600 to NZ$9,130. 10kW system NZ$7,260 to NZ$11,600. Battery add-on (Tesla Powerwall 2, Enphase IQ, BYD HVS) NZ$5,600 to NZ$9,130. Add GST at 15 percent. State expected payback (typically 8 to 12 years in Dunedin) on every quote.
Heritage roof restrictions
Heritage listed Category 1 and 2 stock (most of central Dunedin, Maori Hill, Roslyn) cannot have visible solar panels on street-facing roof slopes. Dunedin City Council heritage planners enforce. Quote rear-roof or hidden-slope install where viable; resource consent (NZ$625 to NZ$2,080) and an 4 to 8 week consent timeline on any visible install. Solar slates (specialty product) may be considered on some heritage roofs but are expensive (NZ$11,600 to NZ$22,850 for a 6kW equivalent).
Battery and off-grid demand
Dunedin's cold winters and Aurora Energy's variable outage record drive demand for battery storage. Quote Tesla Powerwall 2 (NZ$5,600 to NZ$7,260 installed), Enphase IQ Battery (NZ$4,770 to NZ$6,430) or BYD HVS (NZ$4,360 to NZ$6,020). Off-grid systems in Otago Peninsula rural and Wakatipu basin are a niche; quote off-grid sizing fee (NZ$625 to NZ$2,280) and 30 to 50 percent additional system capacity for winter shortfall.
Aurora Energy export tariffs
Aurora Energy (Dunedin's lines company) sets export approval and connection terms. Retailer export buy-back rates vary by retailer (Meridian, Contact, Genesis, Mercury, Octopus Energy NZ); quote a representative buy-back rate (around NZ$0 to NZ$0 per kWh exported in 2026) and state which retailer's terms apply on the quote. State 'retailer subject to client choice' on the commissioning line.

Around 1,250 kWh per kW installed per year (vs Auckland's 1,400 kWh per kW). A 6kW Dunedin system produces around 7,500 kWh per year vs 8,400 kWh in Auckland because of Dunedin's southern latitude (45.9 degrees South). State actual expected output on every quote; over-promising is the number one complaint. South-facing roofs are unusable (true south faces away from sun in southern hemisphere).

Limited. Heritage listed Category 1 and 2 stock cannot have visible solar panels on street-facing roof slopes. Quote rear-roof or hidden-slope install where viable; resource consent (NZ$625 to NZ$2,080) and an 4 to 8 week consent timeline on any visible install. Solar slates (specialty product) may be considered on some heritage roofs but are expensive (NZ$11,600 to NZ$22,850 for a 6kW equivalent).
Tesla Powerwall 2 NZ$5,600 to NZ$7,260 installed. Enphase IQ Battery NZ$4,770 to NZ$6,430. BYD HVS NZ$4,360 to NZ$6,020. Dunedin's cold winters and Aurora Energy variable outage record drive demand. Off-grid systems in Otago Peninsula rural are niche; quote off-grid sizing fee (NZ$625 to NZ$2,280) and 30 to 50 percent additional system capacity for winter shortfall.
Per kW installed in {YEAR}: $500 to $1,040 in the US, £1,200-2,000 in the UK, A$375-1,800 in Australia, R18,000-35,000 in South Africa, and C$995-3,800 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 $125-1,500. Worth it on large projects.
