Solar questions, answered
Short answers with sources. Each links to a page that goes into more detail.
Cost and payback
How much do solar panels cost in NZ?
Typically $11,000 to $13,000 for 5kW, $14,000 to $15,000 for 6.6kW and $15,000 to $18,000 for 10kW installed in 2026 (Solar Scout). See solar panel cost NZ.
How long does solar take to pay back?
EECA says as little as 7 years, or 10 to 12 in other situations. Try the payback calculator.
Is there a government subsidy?
There's no national rebate for homes. Some banks offer low-rate green loan top-ups. See grants and incentives.
Do I need a battery?
Usually not for payback: solar plus battery takes 10 to 14 years to pay back against 6 to 8 for solar alone (Solar Scout). See the battery add-on.
Your home
How many panels do I need?
Yearly kWh ÷ 1,400 gives the size in kW; divide by 0.44 for 440W panels. See how many panels.
Do I need a building consent?
Not for most roof arrays under 40 m² in wind zones up to High, since 23 October 2025. See the consent guide.
Will solar work on my roof?
North, east and west-facing roofs with little shade suit solar best. Metal, tile, concrete and membrane roofs can all take panels with the right fixings. The survey or a solar report confirms it.
What if my roof needs replacing soon?
EECA suggests avoiding solar on a roof that will need replacing within 10 years. Replace the roof first.
Working with us
Who does the installation?
A partner installer we subcontract in your region, with EWRB-registered electricians. We name them before you pay a deposit. See how it works.
When do I pay?
$250 to book the survey (refundable until you sign), a deposit when you accept the fixed-price contract, and the balance after commissioning and certification.
Can I get my $250 survey deposit back?
Yes, in full, if you decide not to sign the contract. Ask and we refund it within 5 working days. See terms of trade.
Which regions do you cover?
We're launching in Auckland, Waikato, Bay of Plenty, Wellington, Canterbury and Otago. Each region takes bookings once its installer is contracted. See regions.
Will you pass my details to other companies?
No, unless you tick the box asking us to refer you where we can't do the job. We'd tell you who first.
