Naumai Solar Farm

Overview

Protecting tomorrow’s energy -today. Signage built for the next generation.

Naumai Solar Farm is a landmark project in Northland’s push for regional energy independence. Located in Ruawai, it uses 7,500 solar panels with sun-tracking capabilities to meet most of the district’s daytime power needs.

Infratec needed a signage solution that matched the farm’s long-term design life - and Identimark delivered. Our U3 signs, backed with Natgum adhesive, are built to last over 40 years, providing clarity, safety, and reliability without ongoing maintenance.

U3 signage lifespan exceeds 32+ years

Fast, secure installation using Natgum adhesive

Fully compliant safety and asset ID labelling

Continued partnership with Infratec for high-spec renewable projects

Challenge

What needed to be solved.

As a future-focused renewable energy project, Naumai Solar Farm was designed to operate reliably for three decades with minimal maintenance.

That meant every product used - from panels to labels -had to be built for durability. Signage, in particular, needed to maintain legibility and compliance for the entire asset lifecycle. Infratec needed a signage partner who understood this, and could deliver without compromise.

Key challenges included:

30+ year operational life: All components had to meet long-term performance specs.

Minimal maintenance model: Any sign failure would compromise asset clarity and compliance.

Environmental exposure: Signage needed to withstand rural weather and high UV conditions.

Identimark worked with Infratec to scope a full signage package tailored to the needs of solar infrastructure. Using our fade-free U3 material and Natgum adhesive system, we delivered long-life signage that installs fast and stays secure, ensuring compliance without the cost of rework. Every sign was engineered for visibility, safety, and endurance in Northland’s rural climate.

The result is a solar site that looks as good as it performs, delivering safe, clean power for the community with signage built to last just as long.

Key solutions included:

U3 High-Durability Signage

UV-stable, fade-free, and compliant - engineered to last over 32+ years without degradation.

Natgum Adhesive System

Quick to install and field-tested for long-term adhesion across metal and composite surfaces.

Custom Solar Signage Design

Labelling and safety warnings aligned with Infratec’s asset standards and visual guidelines.
