Everything you need to know about Solar Energy in Málaga

  • Why is it so profitable to install solar panels in Málaga and the Costa del Sol? Málaga is one of the provinces with the most sun hours in Europe (over 3,000 hours per year). This allows a photovoltaic installation to pay for itself much faster than in other regions, enabling savings of up to 70% on your electricity bill from the very first month.
  • What is surplus energy and why shouldn’t I give it away for free? Surplus energy is the power your panels produce but you don’t consume at that moment. Utility companies usually pay for it at a very low price. At Luz Solar Málaga, we recommend installing batteries to “store” that sunlight and consume it at night, thus avoiding giving your energy away to the grid.
  • How long does a solar panel installation last? A well-executed and maintained installation has a lifespan of more than 25-30 years. Current components, such as those from Enphase or Huawei, offer very solid long-term performance warranties.
  • What maintenance do my solar panels need in winter? In Málaga, winter brings strong gusts of Poniente and Levante winds. It is vital to perform a retightening of the bolts and mounting clamps to prevent vibrations or structural damage. Preventive maintenance ensures your system remains safe and efficient.
  • How does dust and the Málaga “calima” affect my panels? Environmental dust and bird droppings create a layer that prevents light from reaching the solar cells, reducing performance by up to 20%. We recommend a professional cleaning at least once a year to maintain maximum productivity.
  • Can I monitor my production from my phone? Yes. All our installations include an App (such as Solar.web for Fronius, FusionSolar for Huawei, or Enlighten for Enphase) where you can see in real-time how much you produce, how much you consume, and the status of your batteries.
  • What happens if there is a power outage in my area? For safety, most installations shut down during a power cut. However, with backup systems from brands like Fronius, Enphase, or Huawei, we can configure a Back-up or Island Mode. This allows you to keep the lights on in your home using your battery energy even if the general grid is down.
  • What is an LFP lithium battery and why do we recommend it? Lithium Iron Phosphate (LFP) batteries are the safest and most durable technology on the market. They do not contain cobalt, are very stable against heat (ideal for Málaga summers), and offer more than 10 years of useful life while maintaining great performance.
  • What is the difference between Huawei LUNA, BYD, and Enphase batteries? Each has its advantages: Huawei LUNA is modular and smart; BYD stands out for its high discharge power; and Enphase IQ Battery is a leader in safety by not using high-voltage DC. At Luz Solar Málaga, we advise you on the one that best suits your consumption habits.
  • Do I need permission from my neighbors’ association to install solar panels? According to Article 17.5 of the Horizontal Property Law, you do not need board approval to install panels in a common area for your own self-consumption, although you must provide prior notice or a “responsible declaration” to the administrator or president.
  • How is my installation legalized with the Junta de Andalucía? We take care of everything. Once the work is finished, we issue the Electrical Installation Certificate (CIE) and register the plant with the Junta de Andalucía so you can benefit from surplus compensation and potential subsidies.
  • Is it legal to install a charging point for an electric car in a community garage? Totally legal. You only need to notify the homeowners’ association in writing. The installation complies with the ITC-BT-52 regulation and guarantees that the electricity consumption is charged directly to your private meter.

Installation and Support

A standard residential installation is usually completed within 2 to 3 business days, depending on the complexity of the roof and the number of components. At Luz Solar Málaga, we care about excellence in assembly as much as speed:

    • Day 1: Structure and Waterproofing. We focus on fixing the aluminum structures to the roof using high-resistance materials and specific sealants to guarantee total waterproofing.
    • Day 2: Photovoltaic Assembly and Wiring. We place the panels and run the DC cables to the inverter. We pay close attention to aesthetics, using conduits that integrate seamlessly with the home’s architecture.
    • Day 3: Electrical Connection and Commissioning. We install the inverter, electrical protections, and the battery (if applicable). We finish by configuring the monitoring App so you can see your savings instantly.

Of course. We offer a triple layer of protection:

    • Manufacturer’s Warranty: We work exclusively with world-leading brands (warranties between 10 and 25 years).
    • Proprietary Installation Warranty: We guarantee the quality of our assembly and the waterproofing of our roof interventions in writing.
    • Official Technical Service (SAT): We are authorized technical partners for Enphase, Huawei, Fronius, and BYD. This means we handle repairs or replacements directly without relying on third-party call centers, ensuring fast and secure support.
  • What exactly is “Back-up” mode? It is a configuration that allows your inverter and batteries to continue supplying power to your home automatically when the grid fails, creating an “energy island.”
  • Can I power my entire house during a blackout? It depends on the system. You can choose Critical Loads Backup (lights, internet, fridge) or Full Backup (entire house, including A/C), provided the battery and inverter capacity allow it.
  • How long can my house last on batteries alone? With responsible use (lights, fridge, TV), a standard battery can easily cover a full night or a blackout lasting several hours.
  • Can you repair my installation if another company installed it? Yes. We are experts in diagnosing and repairing systems where the original installer has disappeared or failed to provide solutions.
  • What should I do if my inverter shows an error or a red light? Do not tamper with the electrical panel. Note the error code on the screen or App and contact our technical service. We can often diagnose issues remotely before visiting your home.
  • How can I know if my installation is producing what it should? We perform Performance Audits comparing your actual production with the theoretical yield based on Málaga’s sun hours. If there is a deviation, we find the exact fault.
  • Is it worth paying for an annual review report? Absolutely. A small 10% efficiency loss due to an undetected fault costs much more in lost savings than the price of a professional review. It is the best way to guarantee your savings remain constant for 25 years.

General

Solar thermal energy leverages the power of the Sun in the form of heat, which heats domestic hot water or heating water circuit. Solar photovoltaics converts the Sun’s energy directly into electricity and that electricity is that is used in the circuit of your home or business. The problems associated with wear and malfunction of the solar thermal facilities disappear in photovoltaic solar installations, which hardly require maintenance.
Yes, solar photovoltaics that produce your panels lets you save up to 60% on your current electricity bill. In addition, it lets you reduce the contracted power and optimize the rates in the market, which reduce it even more you invoice.
Installation has a shelf life of 30 years or more, and where one of the panels get damaged, this does not affect the functioning of the others. In addition, the production of the voltage can be adjusted by adding or removing panels.

Regulation

Yes, generation facilities connected to the grid are currently legal. There are two types of solar installations: 1. isolated facilities: those that are not connected to the grid and, therefore, the energy consumed comes from the generation of energy from its solar panels. 2. installations connected to the grid: those that are connected to the grid to complete the needs of consumption. These are those that we offer you.
While in our country than in many sun shines others, it has not been so successful so far for different reasons. The arrival of the solar energy in Spain focused on the development of very large facilities encouraged by subsidies to renewable energy. After the change in late 2010 and until October 2015 regulatory paralyzed installation of panels since the regulatory environment did not accompany him. Today in Spain is legal and is profitable.
NO, for installations up to 10 kW of power (the majority of homes in Spain) doesn’t have any cost and simply remain fixed fees you already pay currently on your light Bill for being connected to the grid. For installations whose contracted power exceeds 10 kW (profiles of consumption more related to business in Spain) there was a proposed TAX (SUN TAX) which currently never had been applied to any solar PV installation and which is under review to delete.
The over electricity generated are injected to the grid and are sold.

Installation

You must have a space available for the installation of the panels, to be able to offer you the solution that best suits you and make a simulation needed on your roof, we will need you provide your exact address and your electric bills from last year, to rely on your consumption curve. Get in touch with us!
Only two requirements are needed: owning a space or roof and have a contract of electricity to its name. If you meet them you can get in touch with us. The majority of houses in flats do not include roof property. Only if you live in the attic and the roof is of your property or if you are the owner of the building you can install.
Our engineering team is responsible for making a technical tailored to your installation project and our experienced technicians are responsible for implementing it.
A normal installation usually takes a few days, depending on the characteristics of your home or business and your roof. However, the process of administrative documents (work permits, records the installation, etc.) can be extended up to two months. These procedures do not depend on us, but we will do everything in our hands to expedite to the maximum the process, keeping you informed at all times of the State of the same.
The Government makes it compulsory register installation in an administrative record or facilities of self-consumption, councils should be issued work permits and other licenses, electricity companies must deal with changes of contract and approve facilities… but don’t worry, we take care of everything!
Our systems do not penetrate the surface of your roof are supported by this and are fastened with completely safe ballast. The installation of panels on roofs is not something new. Installers have many years using and perfecting such operations. Metal structures that we use are of the highest quality and come from reliable manufacturers of proven experience.
No, you can be safe. Prior to installing solar panels on a roof we do static calculations, analyze the load of wind in the area and determine the metal structure that we will put on your roof according to the results of our analysis. In addition, we always installed parallel to the roof panels so that it is impossible to move.

Operation

Yes, solar panels are most effective when the Sun’s rays directly affect them, but continue to generate power when it rains or is cloudy.
Solar panels convert solar energy into electricity during the day. At night you can consume the power from the mains because you’ll still connected to it.
Batteries are not necessary, but these accumulation devices allow you to harness the energy at night or at a time in which your demand is greater than your production capacity. Soon we will include this technology in our solution and will contact him if you are interested in incorporating it.
The solar system does not need much maintenance. We will do periodic checks and monitor your installation, so if by some chance we find a fault in your system, we will let you know and send to one of our specialists to check the operation.
