Case Study: High-Capacity Solar & Battery Installation – Harpenden, Hertfordshire
Project Overview
On 17 April 2024, TEMS Solar completed a high-capacity residential solar and battery installation in Harpenden, Hertfordshire, a historic market town known for its green spaces and community-focused living. The system was designed to maximise energy generation on a south-easterly roof aspect while providing substantial battery storage to support self-consumption and energy independence.
System Design & Specifications
The installation features a total solar PV capacity of 7.83kWp, achieved with 18 JINKO 435W modules. The panels are positioned on a south-easterly roof, optimised to capture morning and midday sunlight effectively.
A Fox H1 5.0kW hybrid inverter manages the solar generation and energy storage system, while a high-voltage Fox ECS 17.28kWh battery allows the homeowner to store significant excess energy for evening use or periods of low sunlight. This large battery ensures maximum utilisation of solar power and minimises grid reliance.
Installation Highlights
The standout feature of this project is the combination of a high panel count with a large high-voltage battery on a south-easterly aspect. TEMS Solar optimised panel placement and inverter sizing to maximise efficiency, particularly during morning peak generation hours.
Results & Benefits
The completed system provides the homeowner with:
High renewable energy generation tailored to a south-easterly aspect
Substantial energy storage for evening or low-generation periods
Reduced electricity bills and increased energy independence
A future-ready system capable of supporting additional household energy needs
Conclusion
This installation demonstrates how careful planning of panel orientation, high-capacity PV arrays, and significant battery storage can deliver a powerful, efficient, and sustainable energy solution. TEMS Solar delivered a system designed to maximise both performance and long-term value.
