The project aims to maximise the benefits of smart energy systems by integrating solar PV, storage batteries, and air source heat pumps. The goal is to enable social housing occupants to power their lives affordably, sustainably, and in alignment with the UK’s net-zero goals.
The ambitious project, led by Together Housing Group, seeks to implement solar and storage in 27,000 social homes in the UK. GivEnergy was selected for its manufacturing infrastructure, quality, and system flexibility, making it ideal for complex requirements. This includes a compact design for installation in challenging spaces and easy scalability for varying household sizes.
In addition to product quality, the company’s API facilitated smooth collaboration with multiple manufacturers and an aggregator, ensuring the project’s overall success. With GivEnergy technology seamlessly integrated with solar PV and third-party air source heat pumps, occupants can store green energy from renewables or the grid during off-peak tariffs, use the stored energy for affordable and clean home power, and manage their energy system with a user-friendly app, resulting in a controlled approach to energy consumption.
The specific projections for the project include an assumed average solar install size of 3 kW peak, utilising PVGIS solar data and 2017 UK government CO2 figures. With a 2017 rate of 0.35156 kg CO2e/kWh, the project is estimated to save 211,200 kg CO2e across all homes, equivalent to 844.8 kg CO2e per house annually. The estimated annual generation is 2403 kWh per house, with 80% assumed for customer use, resulting in potential energy savings of £282.44 to £299.74 per house annually. This represents a 60% reduction in CO2 compared to the average annual domestic electricity consumption of 4000 kWh, contributing to the UK’s net-zero target by 2050.
Converting England’s homes to renewable energy is crucial for the UK’s net-zero target by 2050. While there’s consensus on the need to decarbonise housing, providers require confidence in the sustainability for both tenants and finances.
