Why This Tonbridge Home Went Solar
Like many homeowners in Kent, this customer wanted to:
- Lower their reliance on the grid
- Reduce rising energy costs
- Make their property more environmentally friendly
After analysing their energy usage and property layout, our design team created a bespoke 13.92 kW PV system — one that could comfortably power the home’s needs and deliver an expected annual saving of over £2,100 in the first year alone
System Overview: Built for Long-Term Performance
Here’s what we installed at the Tonbridge property:
32 x 435W All Black solar panels
2 x Fox 10kW H3 Inverters
1 x FOX Energy Cube 9.6kWh Battery Storage System
This combination ensures the home captures, converts, and stores solar energy efficiently — giving the homeowner clean, renewable power day and night.
The system is designed to generate 10,079 kWh of clean electricity each year, significantly reducing the home’s reliance on grid energy.
Maximising Self-Consumption with Battery Storage
Battery storage was a key part of this Tonbridge solar installation.
On sunny days, any excess solar power is stored in the 9.6 kWh FOX Energy Cube battery, ready to be used in the evenings when the sun’s gone down.
This setup helps the homeowner reduce grid dependence by 60%, with only around 40% of their power now coming from the grid. It also means they’ll save even more on electricity costs while protecting themselves from future price hikes.
In fact, this Kent homeowner found themelves protected by the recent increase in the energy bill price cap. Learn more about that here.
The Results – Lower Bills, Higher Efficiency
The results speak for themselves:
- Annual Generation: 10,079 kWh
- Self-consumed energy: 7,408 kWh
- Expected savings: £2,148
- Export income: £411
- Total annual benefit: £2,559
- Expected payback period: 3.5 years
This means the Tonbridge solar system could pay for itself in just a few years — and continue delivering savings for decades to come.
Environmental Impact: A Cleaner, Greener Tonbridge
Beyond the financial benefits, the environmental impact is just as impressive.
This Tonbridge solar installation will save approximately 2,087 kg of CO₂ every year. That’s the equivalent of driving 7,453 fewer miles, or the CO₂ absorbed by 96 trees annually.
That’s a meaningful contribution to making Kent a greener county, one home at a time.
