Solar designed for your site, your demand, and your future
Custom solar systems for homes, farms and large-scale projects across Wānaka, the Upper Clutha and Central Otago
Rising power bills, outages, EV charging and winter demand — we design smart home solar systems to suit your lifestyle and your household.
High daytime load, pumps, irrigation, non-standard sites and ground-mounted systems built for serious demand and long-term savings.
Partner with us for new builds and retrofits. We take care of design, approvals, installation, electrical inspection and commissioning.
We’re proud locals of Wānaka and the Southern Lakes, passionate about helping our community harness the benefits of solar power. We design solar systems that fit your life now and in the future, delivering lasting benefits and real savings.
We start with electrical demand, site conditions and performance, not a pre-set package.
We discuss options for expanding or adding on later, so your system can grow as your needs change.
Ground mounted, high demand and complex systems are our area of expertise
Assessment, designing, approvals, installation, commissioning and handover all with one team.
We help you get the system running the way it was designed to run, and we stay available when you need us.
Rob and Neil bring years of electrical and solar knowledge to complex and challenging jobs, as well as being Mains Parallel Generation endorsed and Rob certified as an electrical inspector.
Our team installs and tests your system for safe operation. Final sign-off by electrical inspector.
We hand over the system and analyse data to ensure you are maximising its performance.
From vineyard operations and dairy farms to commercial properties and industrial usage, we design and install large-scale solar systems that handle high electrical demand, including ground-mounted solar. Our team has hands-on experience with large, complex projects designed to meet the specific requirements and operational challenges of each property.
SigEnergy‘s modular energy ecosystem combines solar generation, battery storage, and smart energy management in one integrated system. Monitor and control your energy production and consumption from anywhere.
You’ll have clear insight into what your system is generating, what you’re using, and what you’re importing or exporting. The Southern Solar team supports the full setup and optimisation process, ensuring your system is configured correctly and operating as intended. You’re then supported by the AI-powered mySigen monitoring app, which provides ongoing insight and confidence in your system’s performance.
Visualise energy flows between solar, battery, grid, and home loads with animated, detailed charts
An advanced AI assistant that analyses usage patterns to optimise battery charging and minimise costs.
Remotely manage and set schedules for smart home appliances and electric vehicle chargers, prioritising the use of excess solar energy (PV Surplus).
Access to comprehensive daily, weekly, and monthly energy reports, including battery performance, self-consumption rates, and ROI tracking.
