Our Simple Process
Solar Island Technology manages the full process from site review through installation and commissioning.
01
Site Assessment
We carry out a professional site visit and technical assessment, including:
- Review of electricity usage and load patterns
- Roof structure and installation suitability
- Solar system sizing and layout assessment
- Energy system configuration (solar, battery, or grid-connected)
02
System Design & Proposal
Following assessment, we prepare:
- Recommended system size
- Estimated energy production
- Layout drawings
- Project cost estimate
We provide a clear and structured proposal tailored to your site.
03
Installation
Once approved, we manage:
- Equipment procurement
- Delivery to site
- Professional installation
- Electrical integration
- Testing and commissioning
All systems are installed to meet Tonga Power requirements and local environmental conditions, including cyclone-rated mounting systems.
04
Commissioning
After installation:
- System testing is completed
- Grid connection approval is confirmed (if applicable)
- The system begins producing energy
For battery systems, backup and self-consumption settings are configured to suit the site’s needs.
05
Ongoing Support
Solar systems require minimal maintenance.
We remain available for:
- Technical support
- Performance checks
