Zero Upfront Cost Solar: What Happened to SolarZero?

SolarZero, New Zealand's best-known zero-upfront solar subscription provider, went into liquidation in November 2024 after roughly 15,000 households had signed up, according to reporting confirmed by the company's then-owner BlackRock and covered widely in New Zealand media. The short version: the subscription model itself didn't disappear, but the largest player collapsed, leaving thousands of homeowners locked into long-term contracts attached to panels on their roofs. If you're weighing up a "no upfront cost" solar deal in 2025, the honest answer is that for most owner-occupiers, a low-interest green home loan now beats subscription on total lifetime cost, on flexibility, and on who actually owns the gear. Below is the full picture: how subscriptions work, where they genuinely suit a household, the exit clauses that catch people out, and why the finance landscape has quietly shifted under the whole model.

What actually happened to SolarZero

SolarZero ran a subscription model: instead of buying a system, you paid a fixed monthly fee (commonly reported in the range of $60 to $100+ per month, depending on system size and battery) over a long term, typically 20 to 25 years. The company owned the panels and battery on your roof; you paid for the energy and the service.

In November 2024 SolarZero was placed into liquidation. At the time it was owned by global investment giant BlackRock, which had acquired it in 2022. The liquidators, Deloitte, were appointed to work through what happens next for the roughly 15,000 households with live contracts.

That number matters. It means a meaningful slice of New Zealand's residential solar fleet was sitting on a subscription arrangement when the provider went under. If you're one of those households, your panels keep generating; the immediate practical question is who now holds the contract, who maintains the gear, and what your obligations are. The liquidation process determines that, and affected owners should be reading every letter from the liquidator carefully rather than assuming the arrangement simply vanished.

The bigger lesson for anyone shopping today is structural, not about one company. A 20-year promise is only as good as the company making it, and a 20-year solar subscription asks you to trust that a business will still be solvent, well-run, and honouring its terms two decades from now. That's a long time in any industry, let alone one moving as fast as solar and storage.

How subscription solar works (and why it appeals)

The pitch is genuinely attractive on the surface, and it's worth understanding why so many sensible people signed up.

• No upfront cost. A fully installed 5kW system in New Zealand runs roughly $9,000 to $13,000 in 2025, and adding a battery can push the total past $20,000. Subscription removes that barrier entirely.
• Maintenance included. The provider owns the system, so they're responsible for keeping it running. No worrying about inverter replacements or panel faults.
• A predictable monthly number. For households on a tight budget, swapping an unpredictable power bill for a fixed-ish monthly figure feels like control.
• No lump sum, no loan on the books. You don't take on debt in the traditional sense.

For a household that genuinely cannot access finance, has no savings to draw on, and plans to stay put for decades, the model can make sense. That's a real group of people, and dismissing subscription outright would be dishonest. But it's a narrower group than the marketing suggested, and the maths underneath deserves a hard look.

The catch the brochures skip: total lifetime cost

Here's the bit the smooth sales process tends to glide over. Add up 20 to 25 years of monthly payments and the number is large. At, say, $80 a month for 22 years, that's around $21,000 in total payments, and at the end of it, in many subscription structures, you may not even own the system outright without a further buyout.

Compare that to buying. A 5kW system bought outright for around $11,000, or financed on a low-interest green loan, is yours from day one. Over the same 22 years you've paid once (plus any finance interest), you own an asset, you keep every dollar of bill savings and buy-back credit, and you control what happens to the system.

The genuinely useful framing is this: with a subscription, the bill savings on your power account are partly offset by the monthly subscription fee. The provider is, in effect, taking a slice of the value the panels generate as their margin and return on capital. With ownership, that entire slice stays in your pocket. We walk through the full ownership maths properly over here: How Much Do Solar Panels Cost?

A worked comparison

Take two near-identical houses in Hamilton, both on the WEL Networks area, both using a fair chunk of power during the day.

• House A signs a subscription at $80/month for 22 years. Total paid: roughly $21,000. The system reduces their power bill, but a portion of that saving is consumed by the monthly fee. They don't own the asset and can't easily modify or upgrade it.
• House B buys the same system for $11,000 on a 0% green home loan over 7 years (around $131/month while the loan runs, then nothing). After year 7, the system is fully owned and every dollar of saving and buy-back is theirs, for the remaining 15-plus years of the panels' life.

House B pays more per month in the early years but stops paying entirely after the loan clears. House A keeps paying for two decades. Over the full life of the panels, House B is comfortably ahead and owns a real asset. That's the structural reason finance has overtaken subscription for most owner-occupiers.

The exit clauses that catch people out

This is where you need to read slowly. Subscription contracts are long-term agreements tied to your property, and the exit terms are where the real risk sits. Across the various subscription and "solar as a service" offers that have operated in New Zealand, the recurring pressure points are these.

• Selling your house. What happens when you sell? In many arrangements the buyer must agree to take over the contract, or you must buy out the remaining term. A purchaser who doesn't want a 15-year solar obligation attached to the property can complicate your sale, and a buyout can run into the thousands.
• Early termination fees. Walking away early typically triggers a fee designed to recover the provider's remaining return. Read exactly how it's calculated.
• Buyout pricing. If the contract lets you buy the system out, check how the price is set and whether it's a fair reflection of a depreciated asset or a number that protects the provider's margin.
• What happens if the provider fails. The SolarZero liquidation made this concrete. Where does the contract sit, who maintains the system, and what are your rights if the company behind a 20-year promise is no longer there to keep it? This is no longer hypothetical.
• Property encumbrances. Some arrangements register an interest against the property. Your lawyer needs to see the full contract before you sign anything, not a summary.

None of this means every subscription is a trap. It means the contract is the product, and you must read it the way you'd read a mortgage, because the term is comparable. If a salesperson won't give you the full contract to take to a lawyer before you commit, that alone is your answer.

Why green home loans changed the equation

The reason subscription made sense to a lot of people a few years ago was simple: borrowing to buy solar was either expensive or hard to arrange. That has changed materially, and it's the single biggest reason to rethink "zero upfront" deals.

Several major New Zealand banks now offer low or zero-interest lending specifically for energy-efficiency upgrades including solar:

• Westpac's Greater Choices Home Loan offers a portion of lending at 0% interest for eligible sustainable upgrades, including solar and batteries, typically up to a set amount over a fixed term. We've broken down the eligibility and the fine print over here: Guide to Westpac's 0% Greater Choices Home Loan
• ANZ, ASB, Kiwibank and BNZ have all run their own green or healthy-home lending products at reduced rates for solar and insulation. Terms and availability change, so check the current offer directly with each bank.

The effect is straightforward. A 0% loan means you can spread the cost of buying your own system over several years with no interest, then own the asset outright and keep the full benefit for the rest of its 25-plus year life. That's the upside of subscription (no big lump sum today) without giving away ownership or locking yourself into a 20-year contract with a company whose future you can't control.

The insight most people miss: you keep the optionality

Here's something the subscription model quietly takes from you, and almost nobody talks about it. When you own your system on a green loan, you keep all your future options. Want to add a battery in three years when prices have dropped? You can. Want to switch retailers to chase a better buy-back rate? You can, freely. Want to add an EV charger and reconfigure how your household uses daytime solar? It's your gear, do what you like.

Under a long subscription, your system is locked to one provider's hardware, one set of terms, and often one preferred retailer relationship. Solar and battery technology is improving and getting more cost-effective every year. Tying yourself to today's hardware for 20 years, on someone else's terms, means you don't get to benefit from any of that. Ownership keeps you nimble in a market that's still moving fast.

Who should still consider a subscription

Being honest about the model means naming where it genuinely fits. A subscription may still suit you if:

• You cannot access any form of finance and have no capital to put down.
• You are certain you'll stay in the home for the full contract term.
• You strongly prefer a hands-off arrangement where someone else owns and maintains the equipment, and you accept paying a premium for that.
• The provider is well-established, transparent with its full contract, and the exit terms are genuinely fair.

Even then, get the full contract in front of a lawyer, model the total lifetime cost against a financed purchase, and go in with clear eyes about what happens if the company changes hands or fails.

Who should not

For most owner-occupiers, especially anyone who can access a green home loan or has some savings, buying makes more sense on the numbers and on flexibility. You should be especially wary of subscription if:

• You might sell within the next decade. The contract can complicate or cost you on the sale.
• You qualify for 0% or low-interest green lending. The financial advantage of subscription largely evaporates.
• You like the idea of upgrading or expanding your system later.
• You want to chase the best buy-back rate by switching retailers freely.

And if your real question is whether solar stacks up for your household at all, that's worth settling first. We work through it honestly, including the homes where it genuinely doesn't pencil out, over here: Are Solar Panels Worth It in New Zealand?

What to do next

If a "no upfront cost" offer has landed in front of you, or you're just starting to look, here's the practical sequence.

• Get the real purchase price first. Before you can judge any subscription, you need to know what buying the same system outright would cost. Check current pricing per watt so you know a fair number when you see one: Current Cost Per Watt for New Zealand Solar Installations
• Check your finance options. See whether you qualify for a 0% or low-rate green loan. If you do, the case for buying is strong.
• If you're shown a subscription, demand the full contract. Read the exit clauses, the sale-of-house clause, the buyout pricing, and the early termination fee. Take it to a lawyer.
• Model the total lifetime cost. Add up every monthly payment over the full term and compare it against a financed purchase. Don't compare the monthly subscription fee against your current power bill; that's not the real comparison.
• Get more than one quote. Pricing and quality vary enormously between installers. Comparing real quotes is the single best protection against overpaying.

Frequently Asked Questions

Is SolarZero still operating in 2025?

SolarZero was placed into liquidation in November 2024, with Deloitte appointed as liquidators to manage the process for around 15,000 contracted households. If you have a SolarZero contract, read every communication from the liquidator carefully and seek legal advice if you're unsure of your position, because your rights and obligations depend on how the liquidation is resolved.

What happens to my panels if a subscription provider goes bust?

It depends on the contract and the liquidation outcome. The physical panels stay on your roof and keep generating, but who owns them, who maintains them, and what you owe is determined by the contract terms and the liquidator's process. This is exactly why understanding the full contract before signing matters so much, and why a 20-year promise carries real counterparty risk.

Is a subscription cheaper than buying solar?

Almost never over the full life of the system. While there's no upfront cost, the total of 20-plus years of monthly payments typically exceeds the cost of buying the same system outright, and you may not own the asset at the end. Buying, especially on a low-interest green loan, usually wins on total lifetime cost.

Can I get solar with no upfront cost without a subscription?

Yes. A green home loan, such as Westpac's Greater Choices 0% lending or similar reduced-rate products from ANZ, ASB, BNZ and Kiwibank, lets you buy your own system and spread the cost over several years with little or no interest. You get the no-lump-sum benefit while still owning the asset outright.

Does a solar subscription affect selling my house?

It can. Many subscription contracts require the buyer to take over the agreement or require you to buy out the remaining term, which can run into thousands of dollars. A purchaser who doesn't want a long-term solar obligation attached to the property may complicate your sale, so check the sale-of-house clause carefully before signing.

How much does a solar subscription cost per month in NZ?

Reported subscription fees have commonly sat in the range of around $60 to $100-plus per month depending on system size and whether a battery is included, over terms of 20 to 25 years. Always calculate the total across the full term rather than judging the monthly figure in isolation.

Are green home loans actually 0% interest?

Some are, for a portion of the lending and within set limits. Westpac's Greater Choices Home Loan offers a 0% rate on eligible sustainable upgrades up to a capped amount over a fixed term, while other banks offer reduced (not always zero) rates. Terms change, so confirm the current offer directly with the bank and check your eligibility before relying on it.

What's the single biggest downside of subscription solar?

Loss of ownership and flexibility. You're locked into one provider's hardware and terms for two decades, you can't freely upgrade, add a battery on your own terms, or switch retailers to chase better buy-back rates, and you carry the risk of the provider's future. Ownership keeps all those options in your hands.

The bottom line

The collapse of New Zealand's largest solar subscription provider was a hard lesson in counterparty risk, but it didn't kill the model so much as expose its weak spot. A 20-year promise is only worth the solvency of the company behind it. For most New Zealand homeowners, the arrival of genuine low and zero-interest green lending has quietly made the whole "rent your panels" proposition unnecessary. You can now get solar with no big upfront hit, own the asset outright, and keep every dollar of benefit and every future option for yourself.

The smart first move is to find out what buying would actually cost on your roof and whether you'd qualify for green finance. From there, the maths usually makes the decision for you.
