Reduce Limited was tasked with assessing the feasibility of a solar and energy storage system for Manor House, a large property in Chipping Warden. After a detailed evaluation, it was determined that a 15kWp solar array would provide the optimal balance between generation capacity and property needs. Additionally, we recommended the installation of 30MWh of energy storage to maximize the use of solar energy. This capacity was later increased to 40MWh to accommodate the increased energy demand from a new swimming pool plant.

Energy Demand and Financial Performance

Prior to the solar installation, Millets Farm’s energy demand was substantial due to the farm’s varied operations, including retail, visitor attractions, and agricultural processes. The solar arrays were installed to cover a large portion of this demand. The Play Barn array alone is expected to meet 41% of its energy needs, while the entire project will contribute significantly to reducing the farm’s overall grid dependency.

The export of excess energy at 12p/kWh provides additional revenue, further enhancing the financial viability of the project. The combination of energy savings and revenue from exported energy is projected to yield substantial long-term savings.

Planning and Approvals

One of the critical stages of the project was obtaining the necessary approvals and planning consent. Reduce Limited coordinated the entire planning application process for both the solar array and the battery storage system. Additionally, we applied for a grid connection for two supplies within the property, ensuring the smooth integration of the new renewable systems into the existing infrastructure.

Design and Installation Coordination

The solar array installation was designed to be ground-mounted, with a hybrid inverter setup incorporating a G99 relay to manage both solar generation and battery charging. The system’s design, as outlined in the final site layout diagram, featured a 17.6kWp photovoltaic array connected to the pool house plant room through high-efficiency DC-to-AC inverters.

Key elements of the design included:

• A 15kW 3-phase hybrid inverter to manage the flow of electricity between the solar array, the grid, and the battery storage system.
• Two separate MPANs for the property’s main house and annex, ensuring proper billing and export monitoring.
• A robust energy storage setup capable of operating in both summer and winter conditions, utilizing grid power for charging when solar energy was insufficient.

The project was a success, resulting in the seamless installation of a 17.6kWp solar array and 40MWh battery storage system. The system now provides Manor House with sustainable energy, reduces reliance on the grid, and allows excess energy to be stored for evening use. With the addition of the swimming pool plant, the property has also been able to accommodate its growing energy needs without compromising its environmental goals.
Overall, the project demonstrated Reduce Limited’s ability to manage renewable energy installations from feasibility assessments through to design, planning, and installation, delivering a tailored energy solution for large properties.
