Yes — New Zealand has excellent solar resource, and with rising electricity prices, most households and businesses see a strong return on investment. A well-sized solar system can significantly reduce your power bills, and adding battery storage means you can use your solar generation around the clock. We'll help you understand the numbers before you commit to anything.

We start with a site assessment and consultation to understand your energy usage and goals. From there we design a system tailored to your property, handle all compliance and paperwork, install the panels and any battery storage, and commission the system. We walk you through everything so you know exactly how it works before we leave.

Yes. If you already have solar panels and want to add battery storage, increase your system size, replace an aging inverter, or fix a fault, we can help. Retrofit upgrades are a cost-effective way to get more out of your existing investment without starting from scratch.

Not necessarily — solar panels alone will reduce your daytime power consumption and can export surplus energy to the grid. A battery lets you store that energy for use at night or during outages, which increases your self-sufficiency. Whether a battery makes sense depends on your usage patterns and goals. We'll give you an honest recommendation based on your situation.

Yes. All electrical work in New Zealand must be carried out by a registered electrician, and all work must comply with the Electrical (Safety) Regulations 2010. Renew Electric is fully licensed and insured, and we ensure all work is certified and compliant — protecting you, your property, and your warranty.

We handle all residential and light commercial electrical work including new builds, renovations, lighting design and installation, switchboard upgrades, safety inspections, fault finding, and more. If it's electrical, chances are we can help — contact us to discuss your project.

Yes — this is one of our specialist services. We provide technical solar consulting for commercial clients who are exploring solar energy options, and we also support other electricians who need expert guidance on solar system design, installation methodology, or compliance requirements. If you're an electrician looking for a solar specialist to collaborate with, we'd love to hear from you.

The easiest way is to contact us through our website, or call us directly on 027 42 32631. We'll have a no-pressure conversation about what you need and put together a clear, itemised quote. We're open weekdays 8am–4pm.

A standard residential solar installation typically takes one to two days on site, depending on system size and roof complexity. The design and consent process happens beforehand, and we aim to make the whole experience as smooth and disruption-free as possible. We'll give you a clear timeline when we provide your quote.
