The Three-Step Home Energy System
Solar → Battery → EV Charger
Build a complete home energy system in three steps. Each stage delivers real savings on its own — combined, they can cut your energy costs by £2,000–£3,000 per year and charge your electric car for less than 2p per mile.

The Three Steps Explained
Each step builds on the last. You can start at Step 1 and add more later, or install all three together for the biggest bundle saving.
Start with Solar Panels
The Foundation — Generate Free Electricity
Solar panels generate free electricity from daylight hours — typically 8am to 6pm depending on the season. A well-designed system produces more energy than most households can use during the day, with the excess currently exported to the grid at a low Smart Export Guarantee rate (6–15p/kWh). This is the essential starting point, and for many households it makes sense to add battery storage at the same time rather than retrofitting later.
What You Get
- 4–10 kWp AIKO solar panels (highest efficiency available)
- SolarEdge or SMA inverter with lifetime warranty
- Smart monitoring via app — see real-time generation
- MCS-certified installation, 0% VAT
- Up to 30-year panel performance warranty
- Smart Export Guarantee registration included
Expected Savings
Annual Saving
£700–£1,400/yr
Typical Payback
6–8 years
Homeowners looking to reduce electricity bills and make their first investment in clean energy.
Add Battery Storage
Store Your Solar — Use It Day and Night
Without a battery, solar panels can only power what you are using at the moment they are generating. Add a battery and you store the excess energy from midday for use in the evenings when electricity is at its most expensive. The difference in savings is dramatic: without a battery, households typically self-consume 30–40% of what their panels generate. With a battery, this rises to 70–80%. A battery also provides backup power during outages if installed with a hybrid inverter.
What You Get
- Tesla Powerwall, Hanchu, Fox ESS, or Sigenergy battery
- Lifetime battery warranty
- 5–14 kWh usable capacity (sized to your usage)
- Backup power capability (hybrid inverter)
- Tariff optimisation — charge from cheap overnight rates
- Battery management app integration
Expected Savings
Annual Saving
£1,200–£2,000/yr total
Typical Payback
5–7 years (combined)
Solar panel owners or new installations where evening energy use is high, or where grid outages are a concern.
Add an EV Charger
Charge Your Car for ~2p/Mile
Pairing a home EV charger with solar panels and a battery creates a complete home energy ecosystem. Your solar system charges the battery during the day; your EV charges from the battery in the evening using free solar energy. A typical EV driving 10,000 miles per year saves £800–£1,400 annually compared to petrol, and when charged with solar electricity the per-mile cost drops below 2p. Smart solar-diverting chargers automatically route excess solar generation directly to your car.
What You Get
- 7kW smart home EV charger
- Solar divert functionality — charges from excess solar first
- App-based scheduling and smart tariff integration
- NAPIT-certified installation
- OZEV-compliant installation documentation
- Pairs with any EV or PHEV on the market
Expected Savings
Annual Saving
£800–£1,400/yr additional (vs. petrol)
Typical Payback
Under 2 years
EV owners or those planning to switch, who want to minimise running costs by charging with their own solar electricity.
Combined System Savings Over 25 Years
Based on typical South Yorkshire household usage (4,000 kWh/yr), a 4kWp system, and current electricity prices (24.5p/kWh).
| Configuration | Annual Saving | Payback | 25-Year Total Saving |
|---|---|---|---|
| Solar Panels Only | £700–£1,400 | 6–8 years | ~£18,000 |
| Solar + Battery | £1,200–£2,000 | 5–7 years | ~£32,000 |
| Solar + Battery + EV Charger | £2,000–£3,200 | 4–6 years | ~£48,000 |
Savings are estimates based on current energy prices and typical usage patterns. EV charger saving assumes switching from petrol at 150p/litre, 30mpg. Individual results vary.
