Store solar power instead of giving it away
Your PV system produces electricity during the day, but you need it in the evening. Without a battery, you feed cheap power into the grid and buy expensive power back. A battery storage system changes that.
Without memory
- Feed solar power into the grid for 5 Rappen/kWh
- Buy back electricity in the evening for 35 Rp./kWh
- Only 15-25% self-consumption
- Dependent on rising electricity prices
With Voltera storage
- Use your own solar power in the evening
- 60–80% Own consumption instead of 25–35%
- Save CHF 500–1,500 per year
- Independent from electricity price fluctuations

Frequently asked questions
Quick Answers to the Most Important Questions
How much does a battery storage system cost at Voltera?
The costs depend on the storage size. An 11.5 kWh system starts at CHF 12,900 (purchase) or CHF 149/month (BaaS). You can get an exact price indication for your situation in 2 minutes using the configurator.
Do I need an existing solar power system?
A battery storage system makes the most sense in combination with a PV system. Our modular storage systems are AC-coupled and compatible with all common inverters – ideal for retrofitting existing systems as well.
How long does it take from ordering to installation?
Usually 2-4 weeks after order confirmation. The installation itself usually only takes one day. You can follow the progress live in your customer portal at any time.
Are second-life batteries safe?
Yes. Every battery cell undergoes rigorous testing. Modual's proprietary BMS constantly monitors status, temperature, and performance. All storage units use LiFePO4 cells – the safest lithium-ion chemistry. 10-year warranty included.
Is it possible to start without any equity?
Yes. With our BaaS (pay monthly) or EaaS (optimized electricity price) model, no deposit is required. You benefit from day one - the storage is yours after the contract period.
