Ultimate Guide to Virtual Batteries in the Valencian Community (2026 Edition)
Is it possible to pay €0 on your electricity bill? In the Valencian Community, thanks to the hours of solar irradiation and the current regulatory framework, the answer is a resounding yes. In this guide, we explain how the Virtual Battery (or Solar Wallet) has transformed self-consumption in Valencia and Alicante.
What is a Virtual Battery, Solar Wallet, or Solar Piggy Bank, and how does it work?
Unlike physical lithium batteries, the Virtual Battery is a surplus management service. When your solar panels produce more energy than you consume, that excess is “stored” as economic value (Euros) in a digital piggy bank, rather than in physical kilowatts.
Surplus Generation:
Your panels produce energy while you are not at home.
Standard compensation:
The retailer discounts the value of those surpluses until the energy term of your bill reaches zero.
The power of the Virtual Battery:
If you have more money left over after bringing your energy cost to zero, that balance is saved for the following month or applied to the power term, taxes, or even a second residence.
Advantages of the Virtual Battery in the Valencian Community
Our region is privileged for this system due to three key factors:
High Radiation:
Valencia and Alicante exceed 2,800 hours of sunshine per year, which generates massive surpluses during the spring and summer months.
Real €0 Bill:
With Energías Renovables HG management, we optimize your installation so that the accumulated balance covers 100% of the fixed costs on your bill.
Second Residences:
Many of our clients in Dénia, Jávea, or Benidorm use the surpluses from their primary residence to pay the electricity bill for their holiday apartment.

Quick Questions for Users
Does the Virtual Battery expire?
In most of the retailers we work with at Energías Renovables HG, the accumulated balance does not expire month by month, allowing you to use the savings generated in summer during the winter.
Do I have to switch energy retailers?
Yes, it is necessary to be with a company that offers this service. We handle the process of selecting the one that pays the best rate for surpluses in the current 2026 market.
Can I have both a physical and a virtual battery at the same time?
Yes, it is the configuration for maximum savings. The physical one gives you nighttime autonomy and the virtual one ensures your bills are always €0.
