Battery storage for solar panels in Marbella and across the Costa del Sol, from €4,200 (5 kWh) to €13,500 (20 kWh). Huawei, BYD & Enphase, backup power, up to 90% self-consumption. Free quote in 24h.
A 5 kWh battery starts around €3,500 installed, a 10 kWh system costs roughly €5,500–€7,500, and a Tesla Powerwall installation is typically €9,500–€12,000 including the hybrid inverter and commissioning.
Size the battery to your evening and night consumption. An average Costa del Sol household uses 8–12 kWh after sunset, so 10 kWh covers most homes, while villas with pool pumps and air-conditioning often need 15–20 kWh. We calculate this from your actual Endesa consumption data.
Yes, when the system is installed with backup functionality. We fit a backup gateway so essential circuits — lighting, fridge, internet, alarm and water pump — keep running automatically during a grid outage and recharge from your solar panels the next day.
The lithium (LFP) batteries we install are rated for 6,000–10,000 cycles, which is 15 years or more of daily use, and come with a 10-year manufacturer warranty guaranteeing at least 70% of the original capacity at the end of that term.
