Maximising Self-Sufficiency with Solar and Battery Storage in Falmouth

How we helped Greg harness the Cornish sun to power his home in Falmouth with a high-efficiency 5.4kW solar PV and GivEnergy battery system.

10th February, 2026


Natural Generation customer Greg approached us as he was looking to reduce his reliance on the grid, as well as to protect his home against rising energy costs.

Living in Falmouth, Greg's house was perfectly situated to benefit from solar gain, but the goal was not just to generate energy; it was to keep as much of it as possible for use within the home, day and night.

 

The Solar System We Installed

To meet the high demand for self-sufficiency, our team designed a system that paired high-wattage modules with a substantial storage capacity.

  • Solar Array: 12 x 450W Trina Solar modules (5.4kW total capacity)
  • Inverter: GivEnergy Hybrid Inverter
  • Battery Storage: 9.5kWh GivEnergy Battery

By installing 450W Trina modules, we maximised the power density of the roof space. The integration of the GivEnergy 9.5kWh battery allows Greg's household to store excess generation during the day to power the home through the evening, significantly reducing the need to buy electricity from the grid.

 

The Results

The system is projected to produce an impressive 5,538 kWh of clean energy annually, and with the large battery capacity and intelligent inverter management, Greg can enjoy up to 90% self-sufficiency.

This means that for the vast majority of the year, the home runs entirely on sunshine, leaving them almost entirely independent of volatile energy prices.

 

Customer Feedback

Greg was delighted with the professional installation and the communication throughout the project:

"Just like to say a big Thank You to the whole team for taking us through this process, we are very happy with the panels and battery. The solar panel team were efficient and tidy, Robin the electrician was great, very easy to discuss potential routing issues and come up with an amicable plan. I will definitely recommend Natural Generation to others."

Nothing makes our week quite like feedback like this!
