St. James’ Hall, Long Bennington

The Project

The 28.05 kWp solar installation comprises 55 AIKO Neostar 2S+ 510W panels, a SolaX three-phase hybrid inverter and battery storage. Multiple roof areas with different orientations and pitches were individually assessed and modelled to create a balanced system focused on genuine energy performance rather than simply maximising panel numbers.

Greenio designed and delivered a substantial solar PV and battery storage system for St. James’ Hall in Long Bennington, Nottinghamshire. The community and multi-use venue has annual electricity consumption of approximately 36,000 kWh, with demand varying according to events, operating hours and day-to-day use.

The Customer

Importantly, the original design allowed the energy storage to be expanded later. As real-world usage became clearer, additional SolaX battery capacity was installed in phases, enabling the system to evolve without requiring a redesign of the original solar infrastructure.

The hall wanted a long-term way to reduce electricity costs, lower grid reliance and improve environmental performance, but the investment also needed a clear and realistic financial case. Greenio assessed roof geometry, energy consumption and usage patterns before designing the solar and battery system around how the building actually operates.

The Customer Said...

We needed to know the numbers stacked up before making the investment. Greenio talked us through the options in plain English and designed something around how the hall actually operates. Being able to add more storage later has been a real advantage.

Where Are They Now

The solar PV system is designed to generate approximately 23,731 kWh of renewable electricity annually, with estimated first-year electricity savings of £6,407 from the original configuration and annual carbon savings of approximately 4.9 tonnes of CO2.

Battery storage has subsequently been expanded to 12 x 3.68 kWh SolaX batteries, increasing the amount of solar electricity that can be retained and used on site. The additional capacity supports evening and event-driven demand, reduces peak grid imports and demonstrates the value of designing renewable energy systems with future expansion in mind.
