Lagre overskuddsenergi fra solen til når du trenger den som mest.
Every technician on your roof is a permanent member of our team, trained to our exact standards of neatness and technical precision.
No guesses. We calculate exactly how many kilowatt-hours your specific roof orientation and shading will generate.
We are based in Cómpeta. If you need us, we're a short drive away, not a distant call center.
In the Axarquía region, the sun is abundant, but your energy consumption doesn't always align with peak production hours. This is the fundamental challenge of solar energy: what happens when the sun goes down or when your AC is running at midnight? Traditional net billing (Compensación Simplificada) in Spain allows you to sell surplus back to the grid, but you always sell for less than you buy. At Competa Solar, we specialize in high-performance Battery Storage Systems (BSS) that bridge this gap, allowing you to achieve up to 95% energy independence from the national grid.
Modern battery technology in Spain has evolved from bulky, unreliable lead-acid banks to ultra-efficient Lithium Iron Phosphate (LiFePO4) systems. These aren't just 'backup' devices; they are the heart of a smart energy ecosystem. By storing every excess watt produced during the intense Andalusian midday, you ensure that your evening 'comfort'—from lighting to pool filtration—is powered entirely by the energy you captured hours earlier.
A unique advantage for solar owners in Spain is the 'Batería Virtual' (Virtual Battery). Unlike a physical battery that stores electrons, a virtual battery stores 'euros.' Under Royal Decree 244/2019, any surplus energy you export to the grid can be converted into a monetary credit. With a Virtual Battery service, this credit doesn't expire at the end of the month. It accumulates in a digital 'piggy bank' that can be used to offset your bill's fixed costs, taxes, and even the bills of a second property in Spain.
At Competa Solar, we design systems that maximize this financial lever. For many of our clients, combining a mid-sized physical battery for daily autonomy with a Virtual Battery for seasonal surpluses (like those long July days) results in 'Zero Euro' bills for much of the year. We help you navigate the contracts of providers like Energy Nordic, Próxima Energía, and Lidera to find the most efficient 'monetization' of your surplus.
In the heat of Southern Spain, not all batteries are created equal. High ambient temperatures can significantly degrade the lifespan of lower-quality units. We specify systems with superior thermal management and depth-of-discharge (DoD) capabilities.
Power cuts are not uncommon in rural parts of the Málaga province. Most standard solar systems shut down during a grid failure for safety reasons. However, with a 'Full Backup' battery configuration, your home stays powered. We install 'Automatic Transfer Switches' (ATS) that disconnect you from the grid and activate your battery storage in less than 20 milliseconds—so fast you won't even see the lights flicker.
Furthermore, for clients in areas where the grid connection is 'saturated' and won't allow export, we implement 'Zero-Injection' protocols. The battery acts as a buffer, soaking up every available solar watt and ensuring nothing is 'leaked' to the grid, maintaining 100% compliance with local Endesa/i-DE infrastructure requirements while maximizing your personal consumption.
“We conduct an 'Energy Flow Audit' before every battery installation, identifying your peak evening draws (ovens, heaters, motors) to size your battery's 'C-Rating' correctly. This ensures your battery can actually handle the current you need when you need it.”
Is battery storage worth it? In 2024, the answer is a resounding yes. With electricity prices in Spain remaining volatile and the introduction of 'Time-of-Use' (ToU) tariffs, the ability to 'Peak Shave'—using battery power during expensive peak hours and charging from the sun or cheap off-peak grid power—can reduce your payback period by 30%. In Andalusia, a well-managed battery system adds significant value to your property, as energy-autonomous homes are increasingly sought after by international buyers in the Axarquía market.
