Energy Storage Solutions
A battery isn't always worth it, but when it is, it can make a big difference. We'll be honest about whether one makes sense for your setup.
When Does a Battery Make Sense?
Good Reasons to Add a Battery
- You're out during the day and can't use solar as it's generated
- You're on a smart tariff: charge at 7p/kWh overnight, use it at peak rates
- You want backup power for outages (useful in rural Devon/Cornwall)
The Financial Picture
- Typical savings: use 70-80% of your solar generation instead of 40-50%
- Smart tariff arbitrage can save £300-500/year on top of solar savings
- Most systems are expandable. Start with what makes sense now, add more later
