Solar finance and green loans in Wellington need checking before work is booked. We are not a lender and do not make lending decisions. We prepare a clear installation scope and explain information lenders may request, including a quote, property details, equipment scope and any programme conditions for the installer and proposed work at your specific property address in advance.
What is included in a solar finance discussion
We begin with the project you are considering, such as rooftop solar, a battery, an inverter replacement or an expansion. We then prepare a clear quote scope that describes the proposed work, site considerations and electrical documentation. This gives you a practical document to discuss with your bank or mortgage adviser. We do not act as a lender, promise approval or represent that a particular product is suitable for every borrower.
We also explain the questions that may affect the scope, including connection requirements, export settings, roof work and whether storage is intended for self-consumption or backup. Lenders may ask for their own documents or use their own eligibility rules. We recommend confirming the current terms, approval process and any installer requirements directly with the lender before committing to work.
Signs it is time to check finance options
It can be useful to check finance before finalising a solar project when the property has a mortgage and you want to understand whether a home-loan top-up is available. It is also sensible when you are comparing solar-only, solar-and-battery or an upgrade, because the lender may define eligible work differently. Starting this conversation early can prevent a quote being prepared around assumptions that do not meet the bank's current criteria.
You may also need clarification if a lender requires a quote from an installer with a particular membership or provider status. The Sustainable Energy Association NZ provider directory supports green-loan eligibility for several banks. ANZ states that its Good Energy home loan requires a quote from a SEANZ-member installer. We will confirm what your lender needs; we do not claim SEANZ membership.
Green loan top-ups and other ways to fund work
These are lender products, not an offer from us, and terms can change.
A home-loan top-up may suit some owners, while others may prefer to use savings or another finance arrangement. The useful comparison is not only the repayment method. It should include the proposed scope, expected electricity-use pattern, export limits and whether a battery is needed for backup or only later-day use. We can provide a clear quote scope, but your lender decides eligibility, rate and approval.
What affects the financing scope
The finance conversation is affected by the type of work, property ownership, existing mortgage arrangements, lender criteria and the documents requested. The installation scope itself can change with roof condition, wind exposure, shading, switchboard work, battery location and lines-company requirements. We set out these practical components clearly so you can ask the lender about the exact project, not a vague solar allowance.
For grid-connected projects, the network may set export conditions that affect the design. Published buy-back rates are typically below import prices, so self-consumption is usually more valuable than export. We therefore explain solar sizing around useful on-site electricity use rather than presenting exported energy as a fixed source of income. Lenders will have their own assessment of affordability and security.
Wellington region connection steps before finance is final
A lender quote should reflect the address and the network that serves it. Wellington Electricity serves Wellington City, Porirua, Lower Hutt and Upper Hutt, while Electra serves Kāpiti Coast and Powerco serves Wairarapa. Their distributed-generation application processes differ. We identify the relevant lines company and explain what needs to be confirmed before installation work is scheduled.
Wellington conditions also matter to the scope presented for finance. Hills, valleys and tree cover make shading site-specific, while many sites have higher wind exposure. Coastal properties can need corrosion-exposure assessment for frames and fixings. We include these project factors in the quote discussion so the lender documentation is based on an address-specific scope rather than a generic system description.
How the work is planned
- Tell us whether you are considering solar, a battery, repairs or an expansion and which lender you plan to approach.
- We assess the address, roof, shading, wind exposure, electrical scope and relevant network connection requirements.
- We provide a clear quote scope for you to discuss with the lender or mortgage adviser.
- You confirm current lender terms, eligibility, approval requirements and any SEANZ-member quote condition directly with the lender.
- Once funding and scope are confirmed, we coordinate electrical work, lines-company steps and required documentation.
What a good solar quote should show
Verified lender terms, clearly attributed
We identify these as lender information, not a finance offer from us, and ask you to check current terms directly.
Installer requirements are stated plainly
ANZ states that its Good Energy home loan requires a quote from a SEANZ-member installer. The Sustainable Energy Association NZ provider directory supports green-loan eligibility for several banks. We do not claim SEANZ membership. Instead, we will confirm what your lender needs before you rely on a quote for an application. This keeps the funding discussion accurate and avoids implying eligibility that the lender must decide.
The quote reflects the actual property
We prepare the solar scope around the address, roof, shading, wind exposure, electrical work and network process. That helps you present a concrete project to your lender rather than a generic allowance. It also makes room to explain optional storage, backup and export constraints separately. We do not promise lending approval, savings or a particular return, because those depend on lender terms and the property's eventual system design.
Your questions, answered.
Are you a lender?
No. We do not provide finance, make lending decisions or guarantee approval. We prepare an address-specific quote scope and explain project requirements for your bank or mortgage adviser. The lender decides eligibility, available products and required application documents directly.
What are ANZ's published green loan terms?
It also requires a SEANZ-member installer quote. Check ANZ's current conditions directly because products and eligibility can change.
What are BNZ's published green loan terms?
Confirm current terms, eligibility and application details directly with BNZ.
What might a lender ask for?
Requirements differ by lender, but may include a quote, property and loan information, proposed work and evidence that programme conditions are met. Some require a quote with a specified installer status. We provide a clear scope and confirm what your lender needs, but it sets the final list.
Should I finance a battery as well as solar?
It depends on your use pattern, backup priorities, export setting and lender eligibility rules. A battery stores energy for later and provides outage support only with backup capability. We explain the technical scope and trade-offs, while the lender advises on finance terms and affordability.
