Lewes District Council partnership continues to deliver real results for residents

We’re proud to share a fantastic outcome from our ongoing partnership with Lewes District Council, as part of their drive to make homes more energy-efficient and sustainable.

On 25th July, our team completed the installation of a 3kW solar PV system with a 4kW battery at a property in the Newhaven. In just under two weeks, the system produced 88kWh of electricity, enabling the household to achieve 78.93% energy self-sufficiency.

Key Highlights:

✅ £13 per week estimated savings on electricity bills*

✅ 88kWh of clean energy generated in less than 14 days

✅ 72.84kg of CO₂ emissions avoided

What makes these results particularly exciting is that they were achieved during a period of mostly cloudy and unsettled weather. As sunnier days return, energy production is expected to rise even further — increasing both the household’s savings and the environmental benefits.

Part of a Bigger Picture

This installation is one of many we’ve completed as part of Lewes District Council’s solar and battery programme, which is a key part of their wider climate and sustainability strategy. The goal is to help residents:

• Lower energy bills

• Reduce their carbon footprint

• Become more energy independent

Earlier Installation Shows Long-Term Benefits

One household we worked with back in December 2024 has now generated 2,340kWh of electricity this year alone — saving them an estimated £700* and cutting their carbon emissions by 2.03 tonnes.

Even with slightly lower self-sufficiency, the long-term savings and environmental gains are impressive and continue to grow.

We’re excited to keep supporting local authorities and residents on their journey to a more sustainable future. If you'd like to know more about our solar and battery solutions, or how we can support your community, get in touch with us.
