In the pursuit of renewable energy and sustainability, many homeowners are turning to solar power and innovative energy management systems. This case study highlights the experience of a family who has embraced these technologies, achieving greater energy independence and contributing to a greener planet.

This family began their renewable energy journey in 2011 and 2012 by installing solar (PV) panels through the Feed-in Tariff (FIT) scheme. This programme guaranteed payments for the solar energy they generate over a 25-year period. As of 2024, they will have fully recouped their capital investment through FIT receipts, while simultaneously reducing their reliance on imported energy. With 12 years remaining on the FIT scheme, they consider this initiative a resounding success.

In 2016, they enhanced their energy efficiency by adding a Powervault 4kWh battery storage unit to enable them to store excess solar energy for later use, further optimizing their energy management.

The family has chosen Octopus Energy’s Agile tariff, which adjusts electricity prices every half hour based on wholesale rates. With a smart meter in place, they receive real-time updates on their energy consumption.

They have also taken advantage of Powervault’s SMARTSTOR software to maximise their savings.

‘SMARTSTOR manages everything for us: when to force charge the battery, when to draw power from the battery to meet demands in the house, how to ensure we have battery storage capacity available to store more power for use later, and it also checks the weather forecast to maximise our solar generation. We think it’s a brilliant system. For example, this month it has reduced our electricity imports from the grid by 30% and at the same time has arranged our imports to occur at times when the cost per unit is lowest. With Powervault plus Octopus we can choose the best time to turn on our household appliances.’

With no space for additional PV panels and wind power not feasible for their small garden, the family sought other renewable energy opportunities. They recently invested in a share in a 200kW wind farm developed by Ripple Energy, a cooperative society. Scheduled to begin generation at the end of 2026, this project promises to provide energy at costs well below wholesale prices. The difference will be credited to their Octopus Energy account, reducing their overall electricity charges. Ripple Energy will also handle all maintenance and repairs, making this a low-maintenance investment.

This family’s commitment to renewable energy has not only led to substantial financial savings on their energy bills but has also positioned them as proactive stewards of the environment. By integrating solar power, battery storage, and wind energy, they are reducing their carbon footprint and contributing to a sustainable future.

As they look forward to the benefits of their wind farm investment, they remain optimistic about further decreasing their energy costs and enhancing their positive impact on the planet. This case study serves as an inspiring example for others interested in transitioning to renewable energy solutions.
