NZ-wide, Auckland-based
Right system. Right roof. Right installer.
We've vetted installers across Auckland and the wider region - comparing design quality, warranty, real-world production, and post-install support. So your system fits your home, not a sales template.
See our 5-step processWho We Are
Independent. Customer-first. Built for New Zealand.
SGS is an independent solar advisory and installation coordination company based in Auckland. We are not tied to any single installer or brand. Our loyalty belongs to one party only - the customer.
New Zealand's solar market is growing rapidly, but quality, pricing transparency and technical standards vary widely. SGS exists to help customers make informed, safe and long-term optimal decisions in a complex market.
Our Vision
To become New Zealand's most trusted solar decision-making advisory platform - so every home and business can transition to clean energy with confidence.
- Solar energy is a key part of the future energy landscape.
- Installing solar does not automatically mean installing the right solar.
- Proper system design matters more than brand names.
Our Core Values
Four principles, every project.
Client-First, Always
Every recommendation we make is judged by one standard: what serves you best over the next 25 years.
Grounded in Real Numbers
Real production estimates, consumption patterns, ROI calculations and risk analysis — so every choice rests on numbers, not narratives.
Safety & Compliance First
We only work with installers who meet New Zealand electrical safety and AS/NZS installation standards.
Long-Term Value, Not Lowest Price
The cheapest system often hides undersized inverters, poor configuration, no shading analysis and weak after-sales support.
How It Works
How SGS picks the right installer for you
We don't recommend one installer to everyone. We match the right installer to the right client.
- 01
Energy Profile Analysis
Power bills, consumption patterns, day vs. night usage, battery suitability, future load growth (e.g. EVs).
- 02
Roof & Site Assessment
Roof orientation, pitch and shading, installable capacity, grid connection and switchboard capacity.
- 03
Multi-Installer Comparison
From our installer network we compare design logic, realistic production estimates, equipment, warranty and true value.
- 04
Risk Screening
We flag overpromised production, unrealistic ROI claims, unnecessary battery upselling and hidden installation risks.
- 05
Installation Oversight
We help you confirm the system matches the contract, the install quality is sound and monitoring is operational.
