What's a virtual battery?

A virtual battery is like a piggy bank that allows you to store the surplus from your solar panels and convert it into a financial discount on your electricity bills. A virtual battery stores all the energy that, for legal reasons, can't be deducted from the bill for the period during which it's been generated. It's returned in the form of a discount, whether on that bill, later bills or bills for other services. Find more information about virtual batteries below.

How can I get a virtual battery?

To have a virtual battery, you'll need solar panels that are installed and working. You can link all the supply points you like to that virtual battery, whether or not they have panels, as long as they're in the same name. The corresponding discount will be applied to them all.

Supply points with solar panels will help charge your virtual battery when there's excess surplus. They will also drain your virtual battery so your bills can be cut down to €0.
Supply points without solar panels will drain your virtual battery, and you'll get significant discounts that could even cut your bills down to €0 if enough surplus has been stored.

FAQs

Is surplus stored in kWh in a virtual battery?

No. We store the financial value (€) of any surplus not compensated in your virtual battery.
Why can't I link contracts in other names to my virtual battery?

Ceding your surplus to a third party would be a donation, and would have tax implications.
Does surplus expire?

No. You'll only lose your surplus if you cancel all the contracts you have linked to us.
Is a virtual battery better than a physical battery?

Physical batteries can cut down your electricity bills even more than virtual batteries can, but they involve a large investment. The Holaluz Cloud virtual battery means you get compensation for 100% of your surplus, and enjoy a significant extra saving without having to shoulder that cost.
