Earn £54+ Per Month with Battery Arbitrage
Buy electricity at 7p off-peak, sell at 17p per kWh with 2 cycles per day. Scotland's smartest way to maximize your battery earnings through arbitrage.
Real Example: 10kWh Duracell Battery + Octopus Tariff
Battery Capacity

How Battery Arbitrage Works:
Step 1: Charge at 7p Off-Peak
Charge 10kWh from grid during off-peak hours (00:30-04:30) at just 7p/kWh
Step 2: Discharge During Day/Peak
Use or export 9kWh (90% efficiency) during day, saving/earning 17p/kWh
Step 3: Repeat 2 Cycles Daily
18kWh throughput/day × 10p profit/kWh = £1.80/day (£54/month)
Step 4: Add Solar for Even More
With solar, charge free during day + cheap grid at night for maximum arbitrage
This is based on a typical Scottish household. Your actual earnings depend on your system size, location, and usage patterns.
