Large Domestic Heat Pump and BESS Client

Challenge

The client aimed to decarbonise their property and achieve self-sufficiency due to occasional power outages. With no existing solar installations and a desire to expand their property with an orangery, the client needed a comprehensive renewable energy solution that could handle increased energy demands while providing income through energy generation.

Solution

To meet the client’s needs, we conducted a detailed analysis of the current and forecasted energy usage. Our solution encompassed:

• Installation of a 120kWh battery and a 30kW inverter to store and manage energy efficiently.
• Initial installation of a 21kWh ground-mounted PV system, followed by an additional identical array to double the generation capacity.
• Integration of an additional 80kWh battery capacity with an additional 20kW inverter to further enhance storage capabilities.
• Installation of a G100 compliant switchgear to manage export limits, ensuring compliance and maximising financial returns from generated energy.
• Future plans to connect hydropower to the battery storage system, further increasing energy generation and resilience.

Results

• Enhanced Energy Capacity: The installations significantly increased the property’s energy generation and storage capacity from zero to 42kWp.
• Income from Energy Exports: The client is now able to generate substantial income by exporting excess energy, with Q Energy’s AI technology automatically managing the storage capacity.
• Prepared for Future Expansion: The infrastructure setup has been future-proofed with provisions for integrating hydropower, aligning with the client’s vision of a fully sustainable and self-sufficient home.

Impact

This project not only transformed the property’s energy system but also set a benchmark for residential renewable energy solutions:

• Decarbonisation: The comprehensive setup supports a substantial reduction in carbon emissions.
• Energy Independence: The client achieved a high degree of energy self-sufficiency, crucial for regions experiencing frequent power outages.
• Economic Benefits: The ability to sell back excess energy provides a continuous income stream, offsetting installation costs and contributing to long-term financial sustainability.

Continued monitoring and optimisation of the system are planned to ensure maximum efficiency and performance. The upcoming integration of hydropower will complete the client’s vision of a diversified and robust renewable energy portfolio.
