Domestic Solar, Battery & EV Charger Installation Case Study – Windsor
Windsor, located in Berkshire, is a historic town well known for its proximity to Windsor Castle and its mix of traditional and modern residential properties. The area benefits from favourable solar conditions in the South East of England, particularly for south-facing aspects that maximise energy generation.
Project Overview
This domestic renewable energy system was installed by TEMS Solar on 8th May 2024, combining solar PV, battery storage, and EV charging to create a highly efficient, future-ready home energy solution.
System Specifications
System Type: Domestic Solar, Battery & EV Charger Installation
Solar PV Capacity: 5.67 kWp
Panels Installed: 14 × JA Solar 405W modules
Inverter: Fox H1 5.0kW Hybrid Inverter
Battery Storage: Fox ECS – 5.8 kWh
System Design & Installation
The system makes full use of a large, south-facing roof, enabling strong solar generation throughout the day. Fourteen JA Solar 405W panels were installed to deliver a total capacity of 5.67 kWp, providing a solid balance between generation and household demand.
A Fox H1 5.0kW hybrid inverter was selected to seamlessly integrate both solar generation and battery storage. The addition of a 5.8 kWh Fox ECS battery allows excess daytime energy to be stored and used later, improving overall system efficiency and self-consumption.
An EV charger was also incorporated into the system, allowing the homeowner to charge their electric vehicle using self-generated solar energy—further enhancing cost savings and sustainability.
All equipment is outdoor-rated, meaning installation did not require indoor space, preserving the usability and aesthetics of the home’s interior.
Performance & Benefits
This integrated system delivers a range of key advantages:
Maximises solar generation through optimal roof orientation
Increases self-consumption with battery storage
Enables low-cost EV charging using renewable energy
Allows excess electricity to be exported back to the grid for additional financial return
Reduces overall energy bills and carbon footprint
By combining multiple technologies, the system ensures that more of the generated energy is used efficiently within the home.
Conclusion
This project showcases how combining solar PV, battery storage, and EV charging can significantly enhance the performance and value of a domestic renewable energy system. Installed by TEMS Solar, the solution provides long-term financial and environmental benefits while maintaining a clean and unobtrusive installation.
