01 · Solar panels

Tier-one panels sized for your roof.

We install Jinko Tiger Neo 440 W and Canadian Solar HiKu6 455 W panels — both Tier 1, both backed by 25-year product warranties and 30-year performance guarantees. Every system is designed in-house using LiDAR roof data and Marlborough's 2,400+ sunshine hours to maximise your yield.

Before solar

  • Average Marlborough power bill: $280/month
  • 100% grid-dependent
  • No export credits
  • Rising lines charges every year

After a 6.6 kW install

  • Bill drops to ~$85/month on average
  • 70–80% self-consumption in summer
  • Export credits of 12 c/kWh to Marlborough Lines
  • Locked-in generation for 25+ years

Estimates based on a north-facing roof at 25° pitch in Blenheim with 1,450 kWh/kWp annual generation and a 34 c/kWh grid rate (Meridian, September 2026).

02 · Battery storage

Store the sun for after dark.

A battery lets you use your solar power at night, ride out grid outages and avoid peak-rate charges. We install three proven systems:

05 · How it works

Five steps from call to kilowatts.

  1. Free assessment

    We visit your property, measure the roof, check your switchboard and review twelve months of power bills. Takes about 45 minutes.

  2. System design

    We model your roof in PVsyst using Blenheim's solar irradiance data and design a system that offsets at least 70% of your usage.

  3. Quote & consents

    A fixed-price quote with no hidden costs. We lodge the building consent application with Marlborough District Council on your behalf.

  4. Installation

    Our crew installs in one to two days. All wiring is completed by a registered electrician to AS/NZS 5033 and tested before sign-off.

  5. Commission & monitor

    We commission the system, connect the monitoring app and register your panel and inverter warranties. Then we come back at twelve months for a free check-up.
