TEMS Solar were commissioned to design and install a fully integrated domestic solar PV and battery storage system at a residential property on Sheep Fair Lane, Overton.
The client selected TEMS Solar based on our strong engineering background and technical expertise, ensuring a high-quality install

System Specification

The installation utilised premium, industry-leading equipment to deliver reliability, efficiency, and long-term performance:

• 24 x AIKO 3S 495W (All Black) Solar Panels
• SMA Smart Energy 6kW Hybrid Inverter
• SMA Sunny Boy 3.68kW String Inverter
• 2 x SMA Home Storage 3.2kWh Batteries (6.4kWh total)
• SMA Home Manager (Energy Management System)

This configuration provides a flexible hybrid energy system, combining solar generation with intelligent battery storage and real-time energy management.

System Design & Installation

The property featured a multi-aspect roof, with panels distributed across all elevations:

• 9 panels – South facing (primary generation)
• 9 panels – North facing
• 3 panels – East facing (morning generation)
• 3 panels – West facing (afternoon/evening generation)

This engineered layout ensures:

• Consistent energy generation throughout the day
• Improved morning and evening performance
• Maximum utilisation of available roof space

By combining hybrid and string inverter technologies, TEMS Solar delivered a system optimised for balanced, real-world energy production rather than peak-only output.

Engineering & Installation Standards

TEMS Solar maintained its commitment to engineering-led installation practices, ensuring long-term reliability and system integrity:

• 6mm PV Ultra DC cable used throughout for enhanced efficiency and durability
• Enviroguard bird protection system installed to prevent nesting and maintain airflow
• Clean, structured cable management
• Full compliance with current electrical and installation standards

Smart Energy Integration

The inclusion of the SMA Home Manager enables intelligent energy control across the property, allowing the client to:

• Monitor generation and consumption in real time
• Optimise battery charging and discharge cycles
• Maximise self-consumption of solar energy
• Reduce reliance on grid electricity

This creates a fully integrated smart energy ecosystem, tailored to the client’s usage profile.

Estimated Annual Generation & Savings

With an installed capacity of 11.88 kWp, the system has been designed to balance generation across all roof orientations.

Estimated Annual Generation

 9,000 – 10,000 kWh per year

This reflects:

• Multi-orientation roof layout
• Reduced efficiency from north-facing panels
• Typical UK weather conditions

Estimated Annual Savings

With 6.4 kWh battery storage and smart energy control:

 £1,900 – £2,400 per year

This includes:

• Reduced grid electricity usage
• Export income (where applicable)
• Optimised energy usage through battery storage

Performance Advantage of This Design

Rather than relying solely on peak midday generation, this system delivers:

• More usable energy across the full day
• Better alignment with household demand
• Increased effectiveness of battery storage
• Reduced reliance on evening grid imports

Project Outcome

The completed system delivers a high-performance, future-ready domestic energy solution, providing:

• Increased energy independence
• Reduced electricity costs
• Lower carbon emissions
• Full visibility and control over energy usage
