The cost of installing a solar panel system in Spain depends on the size of your property, your energy requirements, and the quality of the system installed. On average, residential installations typically range between €4,000 and €9,000, while larger villas or commercial properties may require systems costing €12,000 or more. While the upfront investment may seem significant, solar panels quickly prove their value. With more than 300 days of sunshine per year across Málaga, Cádiz, and Gibraltar, solar systems often pay for themselves in just 5–8 years. After that, you continue to benefit from free, renewable energy and protection against rising electricity costs. Choosing an experienced installer like Complete Property Solutions ensures your system is tailored to your needs and delivers maximum return on investment.

The installation time for solar panels varies depending on the size and complexity of the system. For most residential homes, the actual installation process can be completed in 1 to 3 days, while larger or commercial projects may take up to a week. However, the total timeline may be slightly longer if paperwork, permits, or grid connection is required. At Complete Property Solutions, we handle all planning, logistics, and approvals for you, making the process as smooth as possible. Our experienced solar engineers ensure that panels are installed safely, efficiently, and with minimal disruption to your daily routine. Once fitted, your system begins producing clean energy immediately.

In most cases, standard residential solar panel installations in Spain do not require planning permission, particularly when mounted on rooftops. However, exceptions may apply in protected areas, listed buildings, or for large-scale ground-mounted systems. Commercial installations may also require additional permits depending on their size and location. At Complete Property Solutions, we assess your property before installation and advise whether any paperwork is required. Where necessary, we handle all permit applications and grid connection processes on your behalf. This ensures your installation is fully compliant with local regulations while avoiding unnecessary delays.

Most roofs are suitable for solar panels, but a professional assessment is always recommended. Factors such as the roof’s structure, angle, material, and shading from nearby buildings or trees all influence whether panels can be installed effectively. South-facing roofs with minimal shade generally perform best, but east- and west-facing installations can still be highly efficient. At Complete Property Solutions, our team carries out a full structural and suitability check before installation to ensure safety and maximum efficiency. Even if your roof is not suitable, ground-mounted solar systems may still be an option.

Modern solar panels are designed to be highly durable, with most systems lasting 25 to 30 years or more. Performance gradually decreases over time, but good-quality panels maintain around 80% efficiency even after 25 years. Regular maintenance, such as cleaning and inspection, helps extend their lifespan and ensures optimal output. Inverters, which convert solar energy into usable electricity, may need replacement after 10–15 years, but panels themselves often last decades. At Complete Property Solutions, we use only high-quality panels backed by strong manufacturer warranties, giving you confidence that your system is built to last.

The amount you can save depends on your system size, household consumption, and electricity tariffs. On average, Spanish households see savings of 40–70% on their electricity bills after installing solar panels. With over 300 days of sunshine annually in Málaga, Cádiz, and Gibraltar, solar panels generate consistent energy, reducing reliance on costly suppliers. Adding battery storage can further increase savings by storing excess energy for use at night. Over time, these savings often cover the cost of installation, making solar panels one of the best long-term investments available.

Yes, solar panels still generate electricity on cloudy days, although at reduced efficiency. Modern photovoltaic panels are designed to capture both direct sunlight and diffused light, meaning they continue producing energy even when the weather isn’t perfect. Output may be lower, but in regions like southern Spain, with abundant sunshine throughout the year, this reduction has minimal impact on overall performance. To maximise efficiency, we design systems tailored to your property’s needs and local climate.

Systems designed for optimal year-round performance

Solar panels require minimal maintenance, but regular checks are recommended to ensure maximum efficiency. The most common task is cleaning, as dust, dirt, and bird droppings can reduce performance. In southern Spain, occasional rinsing is usually enough, though professional cleaning may be needed for hard-to-reach installations. Annual inspections of wiring, inverters, and mounting systems also help prevent issues and extend lifespan. At Complete Property Solutions, we offer tailored maintenance packages to keep your system running smoothly.

Yes, keeping your solar panels clean is important for maintaining maximum efficiency. Dust, pollen, salt from sea air, and bird droppings can build up on the surface and reduce energy output. In southern Spain, rainfall often helps to keep panels relatively clean, but a professional clean is still recommended once or twice a year, especially in areas prone to dust or near the coast. For rooftop systems, it’s safer to let trained technicians carry out cleaning, as they use the right equipment and avoid damaging the panels. At Complete Property Solutions, we offer solar cleaning as part of our maintenance packages to ensure your system performs at its best all year round.

Yes, adding battery storage to your solar panel system allows you to store excess energy generated during the day and use it at night. This reduces reliance on the grid, increases savings, and provides greater energy independence. Battery systems are available in different sizes, depending on how much energy you want to store and use. They are particularly useful for households or businesses with high evening consumption. At Complete Property Solutions, we supply and install high-quality solar batteries that integrate seamlessly with your system, giving you round-the-clock access to clean, renewable energy.

Yes, solar panels can be used to charge electric vehicles (EVs), offering an excellent way to reduce both running costs and environmental impact. By generating your own renewable electricity, you can power your car for free rather than relying solely on grid electricity or costly public charging stations. Over time, this can add up to significant savings, particularly for drivers who use their vehicles daily. Our team can design systems that include EV charging integration, ensuring your panels provide enough capacity to meet both home and vehicle needs. This makes solar panels not only a smart choice for your property but also a sustainable solution for transport.
