Job overview

The homeowner, located in Winchester, Hampshire, was keen to minimise their energy consumption and environmental impact. With a high-energy household featuring air source heat pumps, electric cars, and a hot tub, they needed a comprehensive and efficient renewable energy solution.

Vanadium provided a tailored solution, installing 24 solar PV panels and two Tesla Powerwall 3 batteries. The team also integrated a Myenergi Zappi EV charger and ensured seamless connectivity with the existing air source heat pump. Vanadium's transparent approach involved discussing various options, including different PV panel and battery configurations, to achieve the optimal balance for the homeowner's specific needs.

The installation process was smooth and professional, with Vanadium's team completing the work efficiently and without disruption. The homeowner quickly gained control over their energy usage through the intuitive Tesla app, which showed 99% self-powering on the commissioning day. The system was also integrated with an Intelligent Octopus Go tariff, allowing the household to maximise savings by charging electric vehicles and batteries during off-peak hours, making their home significantly cheaper to run.
