If you’re getting ready to put solar on an Auckland roof—or upgrade from a smaller array—this guide will help you quickly compare three solar deals NZ from Solar Republic: 5kW, 7kW, and 10kW. We’ll cover price, what’s included, who each size fits, installation conditions, and practical tips so you can turn sunshine into reliable savings without surprises.
Why these three tiers make sense for Auckland
Auckland households often use the most power in the morning and evening, while rooftop solar peaks through the middle of the day. For many homes, a hybrid (battery-ready) inverter is the smartest foundation: you can enjoy daytime bill cuts now and add a battery later to soak up excess generation for the evening peak. These bundles stand out among solar deals NZ because pricing is inclusive of GST and installation, and the provider handles grid-connection, meter coordination, and compliance paperwork. That removes much of the scope creep that can derail a “cheap” quote elsewhere.
Quick comparison (5kW vs 7kW vs 10kW packages)
If you’re scanning solar deals NZ for installed pricing, here’s the nutshell. The 5kW package is $8,999 (was $9,999) with 12 panels and a 5 kW hybrid inverter. It’s a sharp entry point for ~2–4 people who want a battery-ready system with minimal fuss. The 7kW package is $10,899 (was $12,999) with 16 panels and a 6 kW hybrid inverter; it’s the sweet spot for families of 4+ or anyone with more daytime loads (laundry in daylight, bigger fridges/freezers, pool pump). The 10kW package is $14,999 (was $18,999) with 22 panels and a 10 kW hybrid inverter—ideal for high-usage homes, large roofs, EV charging plans, or near-term battery upgrades.
What’s included (and what isn’t)
All three bundles are genuinely turnkey. Hardware covers high-efficiency panels (12/16/22), a hybrid inverter, roof-mount kit (rails, clamps, brackets, fixings), and electrical & safety materials (AC/DC cabling, conduits, breakers/switches, comms cables, warning labels). Professional services include qualified installation, end-to-end project management, grid-connection consent application, meter upgrade coordination, and compliance documentation (Certificate of Compliance and Electrical Safety Certificate).
Not included: third-party charges such as certain lines-company fees or specific meter upgrades. These pass-through costs are standard across New Zealand; just keep a small buffer in your budget.
Warranties that matter
Good solar deals NZ aren’t just about watts and dollars; protection counts. These bundles include 25-year panel manufacturer warranty plus a 15-year panel performance warranty, a 10-year inverter manufacturer warranty, and a 5-year workmanship warranty on installation defects. Together, they cover the big three risk zones: hardware reliability, long-term output, and the quality of the install.
Standard install conditions (read before you buy)
The list prices assume a standard install: your property is within 50 km of Auckland CBD, the home is single-storey, you have an iron (metal) roof, and the roof pitch is ≤ 25°. If you’ve got a tile roof, a two-storey home, a steeper pitch, or you’re further out, you can still proceed—expect a tailored scope and price to reflect extra access equipment, materials, or time.
How to choose the right size
Think in terms of daytime self-consumption. Exporting to the grid is useful, but you’ll squeeze the best value by using power as it’s generated.
- Choose 5kW if you’re a smaller household (~2–4 people) with moderate daytime activity. Shift washing, drying, and dishwashing into sunny hours and you’ll cover a big chunk of daytime demand. The hybrid inverter lets you add a battery later without re-engineering the system.
- Go 7kW if you’re 4+ people or your daytime loads run higher: multiple work-from-home days, bigger appliances, or a pool pump. The extra panels provide headroom so you import less from the grid when the house is busiest.
- Step up to 10kW if you’re high-usage, planning EV charging, running multiple large appliances in daylight, or you simply have a large, shade-free roof. It’s also a strong match for future medium-to-large batteries, giving you “once-and-done” headroom.
Roof space and layout basics
Modern panels are roughly 1.7 m × 1.1 m. As a quick rule of thumb, allow about 20–24 m² for 12 panels (5kW bundle), 27–32 m² for 16 panels (7kW), and 37–44 m² for 22 panels (10kW), plus room for rails and access lanes. North-facing arrays deliver the strongest yields in Auckland; east/west splits can better match morning/evening demand. Common roof pitches around 20–30° are fine; racking can tweak angles. If you have chimneys, trees, or nearby structures, raise shading during quoting so the designer can optimise stringing and layout.
Turn watts into savings: three practical moves
- Run appliances in daylight. Use timers on the dishwasher, washing machine, and dryer to hit the midday solar peak.
- Prioritise hot water and EVs. Consider a hot-water diverter to capture midday surplus, and schedule EV charging when the sun is strongest.
- Watch the app and adjust habits. Your inverter or monitoring app will show generation vs. consumption—nudge energy-hungry tasks into those bright hours.
Why these bundles stand out among solar deals NZ
There are three reasons these bundles stand out among solar deals NZ: transparent installed pricing (GST included, clear inclusions), battery-ready design (hybrid inverters across the board), and bank finance options to align repayments with typical bill savings. In a rising-power-price environment, that mix keeps both upfront and ongoing costs predictable.
Your pre-purchase checklist
- Book an on-site assessment to confirm roof structure, shading, layout, and cable routes.
- Ask for the panel and inverter datasheets to confirm efficiency, app features, and battery compatibility.
- Ensure your quote clearly states what’s included/excluded and the standard-install boundaries—that keeps delivery aligned with expectations.
Bottom line
For Auckland homes, these tiered solar deals NZ make choosing straightforward. 5kW is a budget-friendly start for smaller households, 7kW is the sweet spot for most families seeking extra daytime headroom, and 10kW suits high-usage homes, EV owners, and anyone who wants to future-proof with a battery. Get the site check, lock in the equipment specs, and you’ll translate sharp upfront pricing into long-term value.
