Battery Storage Installation in Redruth

Battery Storage in Redruth: Add Storage to Existing or New Solar

Redruth is CCS Heating & Renewables' home town, and the TR15/TR16 area has one of the highest installed solar PV densities in West Cornwall. Many of those systems — installed 2015–2020 — were originally solar-only because battery prices were prohibitive. Today, a Foxstar Pro 10kWh or Tesla Powerwall 3 upgrade is a half-day install that lifts your self-consumption from around 35% up to 80%+.

How Battery Storage Pays Back in Redruth

At today's typical electricity prices (around 27p/kWh peak), a 10kWh battery added to a 4kWp solar system saves a typical Redruth household £450–£700 per year. Combined with a battery arbitrage strategy on Octopus Agile or Octopus Flux, savings can rise to £900–£1,200 per year by buying cheap overnight power and using or exporting it at peak times. Payback in 5–7 years is typical, with 10-year manufacturer warranties on most leading systems.

Best Battery Systems for Redruth Properties

• Foxstar Pro 10kWh: Our most-installed battery in Redruth. Modular, expandable to 20kWh+, robust IP65 rating for outdoor mounting in Cornish weather. Excellent value for £4,500–£5,500 fitted.
• Tesla Powerwall 3 (13.5kWh, integrated inverter): Premium choice for Sandy Lane, Pennance, and the executive homes at Park Bottom. Clean aesthetics, strong app integration. Around £8,500–£10,500 fitted.
• FoxESS EP/AIO range: Good mid-range option, particularly suited to retrofits where the existing solar inverter is already a FoxESS unit. AC-coupled installations possible.

The Heat Pump Multiplier

For Redruth households running a heat pump alongside solar, battery storage is particularly valuable. The heat pump draws 2–5kW for a typical heating run — using stored solar to power that load instead of grid electricity at peak rate eliminates the worst portion of your bill. We model this combined effect at the free survey stage. See also our Redruth heat pumps page and Foxstar vs Tesla Powerwall comparison.

0% VAT Until March 2027

Battery storage installed alongside solar PV qualifies for 0% VAT until 31 March 2027 under the residential energy-saving materials VAT reduction. Standalone retrofits to an existing solar installation also qualify. CCS Heating & Renewables handles the VAT zero-rating automatically — there is no separate paperwork for the homeowner.
