A Smarter Energy Strategy for Home and Investment
Peter was looking to take a more strategic approach to his energy use across two properties he owns — his main residence and a rental property. With rising energy costs and a focus on long-term sustainability, his goal was to reduce reliance on the grid, lower running costs and improve the overall efficiency and resilience of both homes.
Rather than treating each property in isolation, Peter wanted a joined-up energy solution that could be tailored to the different demands of each home while still delivering consistent long-term benefits.
A Tailored Solution for Two Different Properties
To meet these requirements, both properties were assessed individually and fitted with bespoke solar PV and EcoFlow battery storage systems. This ensured each installation was matched to its specific energy usage patterns and occupancy type.
The systems prioritise the direct use of solar energy during the day, store excess generation in the battery and discharge stored energy when demand increases or solar production drops. This reduces reliance on grid electricity across both homes.
Property 1: Rental Property
Installation Specification:
- 5.58kW Solar PV System
- 15kW EcoFlow Battery System
- Estimated annual CO₂ saving: 873 kg
The larger system at Peter’s main home was designed to support higher energy usage and maximise on-site generation and storage. With increased battery capacity, the property can store more surplus energy and rely less on grid electricity during peak times and evenings.
This gives Peter and his family greater control over their energy consumption and improves resilience against rising energy costs.
Property 2: Main Residence
Installation Specification:
- 3.72kW Solar PV System (8 panels)
- 5kW EcoFlow Battery Storage
- Estimated annual CO₂ saving: 589 kg
This system was designed to provide a reliable and efficient energy solution for a rental property. It reduces day-to-day electricity consumption from the grid while improving overall energy performance.
By storing excess solar energy for later use, the property benefits from lower running costs and improved efficiency, increasing its long-term appeal and sustainability for tenants.
Combined Project Outcomes
Across both properties, Peter now benefits from a coordinated dual-home energy strategy:
- Increased solar self-consumption across both homes
- Reduced reliance on grid electricity
- Individually tailored system design for each property
- Improved efficiency for both homeowner and rental property
- Greater long-term control over energy usage and costs
Environmental Impact
The combined systems deliver meaningful carbon reductions across Peter’s property portfolio. By generating and storing renewable energy on-site, both homes significantly reduce CO₂ emissions while making better use of clean energy resources.
Conclusion
Peter’s project demonstrates how renewable energy can be successfully scaled across multiple properties with different requirements. By tailoring each system to the specific needs of the home or rental property, he has achieved improved efficiency, reduced energy costs and greater long-term energy independence.
This approach shows that solar and battery storage solutions can be flexibly designed to suit different property types, usage patterns and ownership goals.
