Commercial Solar Panel FAQs

How much do commercial solar panels cost in Auckland?

The cost varies depending on system size, panel type, battery storage, and installation complexity. A small commercial system typically starts from around $15,000–$20,000, while larger warehouse or industrial installations can vary significantly. We provide free, no-obligation quotes — contact us to get an accurate price for your site.

How long does a commercial solar installation take?

Most standard commercial rooftop installations are completed within two to four days. However, larger systems or those requiring switchboard upgrades or grid tie-in applications may take longer. We will give you a clear timeline before work begins.

How long does it take to recoup the investment?

Most commercial solar systems in New Zealand pay back their installation cost within five to eight years, depending on your current energy usage and tariff. After payback, the system generates free electricity for the remainder of its 25+ year lifespan. Furthermore, rising electricity prices shorten payback periods over time.

Do I need resource consent or council approval?

Most commercial rooftop solar installations in New Zealand are permitted activities and do not require resource consent. However, some heritage buildings or specific zones may have requirements. Additionally, grid-tied systems require a Distributed Generation application to your lines company. We handle all of this as part of our installation service.

What happens to surplus solar energy we generate?

Surplus electricity can be exported back to the grid under a buy-back arrangement with your electricity retailer. Alternatively, battery storage allows you to store surplus energy for use later. Therefore, we can advise on the best option based on your energy usage profile and retailer rates.

Do you offer solar for warehouses and industrial properties?

Yes — large roof areas on warehouses and industrial facilities are ideal for commercial solar. In particular, high daytime energy consumption in these settings means solar can offset a significant portion of your power bill. Contact us to discuss your site.
