Grid-tied, hybrid and off-grid systems
Every site is different—so we don’t push a one-size-fits-all solution. We’ll walk you through the pros and cons of different setups to match your budget, property, and power use.
- Grid-tied: Works with the electricity grid, exporting surplus power. Great for homes and urban sites.
- Hybrid: Includes battery storage with grid access for backup. Offers more control and backup during outages.
- Off-grid: Fully independent. Perfect for rural properties, remote sites, or lifestyle blocks with no grid access.
Already off-grid or planning a move? We’ve been installing remote and off-grid setups for years and can design a solution that works year-round, even through Central Otago winters.
Support, monitoring and advice
Our service doesn’t end once the panels go up. We provide ongoing help so you get the most from your system:
- Friendly, local support team—real people, not call centres
- Remote monitoring support using intuitive app-based dashboards
- Advice on future upgrades or usage changes
- Maintenance services, fault repairs, and system inspections
- Battery and system performance checks
- Thermal imaging available for insurance or early fault detection
We also offer periodic verification reports and compliance inspections for commercial systems.
EV charger installation and certification
As electric vehicles become more common, we’re helping homeowners, councils, and businesses set up charging stations safely and efficiently. We install EV chargers for homes and garages, commercial premises, public parking areas, and remote or off-grid sites with solar support.
With the right setup, your EV charger can run on solar power—maximising your energy investment and lowering vehicle running costs.
We handle the entire process—from design to installation and certification. That includes:
- Assessing your current power supply and usage
- Integrating EV chargers with your solar system (if applicable)
- Installing standalone or solar-supported chargers
- Providing EV charger certification and annual re-inspections for public or commercial use
