Your ideal commercial solar partner

Engineered Feasibility & Energy Profiling

 

Anyone can bolt a panel to a roof, but a professional system starts with data. We don't guess; we analyze.

  • Load Profile Analysis: We deep-dive into your half-hourly interval data to align solar generation with your highest usage periods.

  • Structural & Seismic Assessment: Given New Zealand’s unique conditions, we ensure your roof’s structural integrity is verified for solar dead loads and wind uplift.

  • Financial Modelling: Clear, no-nonsense projections on ROI, payback periods (typically 4–7 years), and the IRD Investment Boost tax incentives.

Compliance & Grid Integration

 

Navigating the regulatory landscape is where experience counts. We handle the "hard stuff" so you don’t have to.

  • Lines Company Liaison: We manage the entire application process with your local lines company (Vector or Counties Energy) for solar export and grid connection.

  • AS/NZS Standards Mastery: Every install strictly adheres to AS/NZS 5033 and AS/NZS 4777.1, ensuring your insurance remains valid and your site stays safe.

  • Zero-Export & Battery Ready: We specialize in complex configurations, including zero-export controls for constrained grids and BESS (Battery Energy Storage Systems) for true energy independence.

Asset Management & Performance Monitoring

 

A commercial solar array is a 25-year asset. We ensure it’s an "set and forget" investment for you, while we keep an eye on the metrics.

  • Cloud-Based Monitoring: Real-time visibility into your production vs. consumption via mobile or desktop.

  • Proactive Maintenance: Scheduled thermal imaging (to detect hot spots) and electrical testing to prevent downtime.

  • Performance Guarantees: We use Tier-1 components (panels and inverters) backed by industry-leading warranties, ensuring your system delivers the kilowatt-hours promised on day one.
