BrightGridGenerating solar electricity is only part of the equation. How much of that electricity your home uses directly can influence the financial value of the system. Fortunately, many household loads can be shifted towards periods of stronger solar generation.
Start with simple load shifting
- Run the washing machine during sunny periods.
- Run the dishwasher during solar generation.
- Use appliances with timers.
- Heat hot water during solar production.
- Charge phones and other devices during the day.
- Use an EV charger when solar is available.
Use battery storage
A battery can store surplus solar electricity that would otherwise be exported and make it available later in the evening.
Use your EV as a flexible load
If the vehicle is at home during daylight hours, smart charging can direct surplus solar electricity into the vehicle.
Use solar for hot water
Electric hot-water systems or suitable controls can sometimes be scheduled to use surplus electricity when solar generation is high.
| Load | Potential strategy |
|---|---|
| Washing machine | Run during daytime solar generation |
| Dishwasher | Schedule for solar periods |
| EV | Use smart solar charging |
| Hot water | Heat during surplus generation |
| Battery | Store surplus for later use |
Monitor before changing everything
Your monitoring data can reveal when solar generation peaks and when your household uses electricity. This allows you to target the largest opportunities rather than changing every appliance schedule.
The goal is not to use electricity simply because solar is available
The goal is to shift flexible electricity demand where doing so makes practical and financial sense.

Check Your SavingsFrequently asked questions
How can I use more of my solar electricity?
Shift flexible appliances, hot-water heating and EV charging into periods when solar generation is available, and consider battery storage.
Is it better to use solar electricity or export it?
The best option depends on the value of avoided electricity purchases compared with available export payments and system losses.
Can I charge my EV from excess solar?
Yes, using a compatible smart EV charger.
Does a battery increase solar self-consumption?
A battery can increase the proportion of solar generation used on site by storing surplus electricity for later.
