Why Add Battery Storage?
How battery storage works with your solar system
A home battery stores excess solar energy that your panels produce during the day but your villa doesn't immediately consume. Without a battery, this surplus is exported to the grid at a low compensation rate (currently around €0.05–0.08/kWh in Spain), while you buy electricity back at €0.15–0.30/kWh during evenings and nights. A battery captures that surplus and releases it when you need it — typically from sunset through the night and early morning. This dramatically increases your self-consumption ratio from a typical 30–40% (solar only) to 70–90% (solar plus battery). For a villa consuming 12,000 kWh per year, that difference can mean an additional €800–€1,500 in annual savings. We install lithium iron phosphate (LFP) batteries from BYD, Huawei, and Pylontech, which offer 6,000+ charge cycles and excellent thermal stability for Mediterranean climates.
Blackout protection for Costa Blanca villas
Power outages in Costa Blanca North are more common than many new residents expect. Storm damage, grid maintenance, and summer demand peaks can cause outages lasting from minutes to several hours. For villas with swimming pools, the consequences include pool pump failure leading to algae growth, loss of refrigeration, disabled security systems, and no internet or air conditioning during the hottest periods. A battery with backup functionality maintains power to your essential circuits during grid outages — typically covering refrigeration, lighting, internet router, security cameras, pool pump, and selected power outlets. Our hybrid inverters detect grid failure within milliseconds and switch to battery power seamlessly, with zero interruption to connected devices.
Choosing the right battery size for your villa
Battery sizing depends on your evening and overnight consumption, not your total daily usage. A typical villa in Costa Blanca uses 8–15 kWh between sunset and sunrise. We analyse your smart meter data or estimate from your bills to determine the optimal battery capacity. A 5 kWh battery suits smaller villas with moderate evening consumption. A 10 kWh battery covers most standard villas with pool and AC. A 15–20 kWh battery is recommended for large villas with high overnight consumption, multiple AC units, or EV charging. We always recommend starting with the size that matches your current needs — our systems are modular, meaning you can add battery capacity later without replacing existing equipment. We also help you evaluate whether a battery makes financial sense for your specific situation.
