Note: Evening energy costs are higher because everyone is cooking, watching TV and doing washing up etc. after a long day at work. So by having a battery, you can use generated power during the day instead.
Store Daytime Generation for Later
Your solar panels are typically generating power during the middle of the day, when your home is generating very little. This means that your solar panels can generate power for your battery during the day, and for your home’s use in the evening.
Match Your Battery to Evening Demand
A 5 kWh battery is sufficient to cover evening usage of typical households (2-3 kWh evening usage). Very little Grid import will be necessary during peak hours.
Use Time-of-Use Tariffs
Use Solar Battery Storage with Smart Tariffs. Use overnight cheap rates to top up your Solar Battery Storage and then discharge the energy throughout the evening. This will help cut your evening energy costs.

Set Your Inverter Discharge Schedule
By setting the inverter discharge schedule to match your evening peak usage hours, solar battery storage can cut evening energy costs for your household automatically.
Watch How Export Behaviour Changes
For solar battery installation in the Midlands and South West, see Precision Green Energy (link).
A well-sized battery with a sensible discharge schedule can make evening grid electricity optional.
