Introduction
Following a detailed site survey and technical assessment, ApolloGrid developed a tailored system designed to maximise solar generation across both pitched and flat roof sections while integrating battery storage for increased energy independence.
Customer Background
The property is a large, modernised residential home featuring a combination of pitched and flat roof areas, roof windows, and a recent extension. The homeowner wanted to utilise available roof space effectively while ensuring the installation complemented the property’s appearance and existing architecture.
With rising energy prices and increasing demand for sustainable living, the customer sought a future-proof energy solution capable of reducing reliance on the national grid.
Challenges Faced
Several design considerations were identified during the survey process:
- Combination of pitched and flat roof structures requiring bespoke system design.
- Multiple roof windows limiting panel placement options.
- Large mature trees surrounding the property creating potential future shading considerations.
- Complex cable routing between roof-mounted panels and external system equipment.
- Requirement to maximise generation while maintaining the property’s visual appeal.
ApolloGrid Solution
ApolloGrid designed a customised solar PV and battery storage solution tailored specifically to the property’s unique layout.
The solution included:
- Strategic solar panel placement across both pitched and flat roof sections.
- Hybrid inverter technology to optimise energy generation and consumption.
- Battery storage integration to store excess solar energy for use during evenings and periods of low generation.
- External wall-mounted inverter and battery installation positioned for accessibility and ventilation.
- Smart monitoring functionality enabling real-time performance tracking.
- Carefully planned AC and DC cable routes to ensure a clean and professional installation.
Installation Highlights
- Large detached family home in South West London.
- Combination of pitched and flat roof mounting areas.
- External inverter and battery installation.
