Virtual battery or physical battery: which pays off on the Costa del Sol

2 September 2026 3 min read

A virtual battery stores no electricity: it turns your surplus into a credit your energy supplier applies to later bills, usually with a monthly fee or a lower buy-back rate. A physical battery stores midday sun and releases it in the evening, when the kWh is most expensive, and it keeps the house running during power cuts.

If you only use the house a few months a year, the virtual battery is usually enough. If you live here all year with a pool, air conditioning or an EV, a physical battery (from about 3,000 EUR for 5 kWh, about 5,500 EUR for 16 kWh) pays back in five to seven years.

Full comparison on virtual battery and models on solar batteries.

## Which brands we fit, and why Most readers of this guide end up searching for a specific brand: Huawei inverter, Huawei LUNA battery, Deye inverter or Solplanet. On villas in Marbella and Estepona with palm shade we usually propose [Huawei inverters](/inversores-huawei) with optimisers or the [LUNA2000 battery](/bateria-huawei-luna2000); on the clear roofs of Vélez-Málaga, the Axarquía, Cártama, Coín or Alhaurín de la Torre a [Deye hybrid](/inversor-deye) with Pylontech or LVTOPSUN cells performs almost identically for considerably less. We install, legalise and maintain with our own crew from Coín.
