How We Tailor Your Solar Panel Installation to Your Location
Spain is located in the south of Europe
Spain receives more solar energy than the northern regions of Europe, but less than the African ones. This makes Spain a great place to install solar panels and benefit from clean and renewable energy. We also take into account your location in Spain, as this affects the amount and quality of solar radiation.
Spain is sunnier than the European average
Spain enjoys an average of 2,940 hours of sunshine per year, which is higher than the European average of 1,700 hours. This means that Spain has more potential to generate solar power and save on electricity bills. We also take into account the number of sunny days in your particular city, as this affects the reliability and consistency of solar power.
The sun's rays have different angles of incidence in Spain
Spain lies between 36° and 43° north latitude. This affects the efficiency of solar panels. The closer to the equator, the more solar energy there is. That's why we adjust the tilt and orientation of the panels to suit the location. We also take into account the angle of incidence of the sun's rays for each area, as this affects the intensity of the solar radiation.
Spain has different climates in different regions
Spain has a Mediterranean climate in the south and an Atlantic climate in the north. High temperatures reduce the efficiency of the panels and high humidity increases the risk of corrosion. That's why we use high quality materials and protective coatings for our panels. We take into account the different climates in the different regions of Spain.

How do Solar Panels Work (for Those Unfamiliar)
Understanding the Mechanism of Solar Cells: A Step-by-Step Overview
Step 1: Absorbing Solar Radiation
Solar panels operate by harnessing the power of sunlight and transforming it into direct current (DC) electricity. Through photovoltaic cells composed of semiconductor materials, solar panels absorb photons from sunlight, initiating an electron flow within the cells.
Step 2: Conversion to Alternating Current (AC)
To align with the requirements of commonly used electronic devices and appliances, the generated DC electricity must undergo conversion into alternating current (AC) electricity. This transformation is facilitated by an inverter, which ensures compatibility with various household items.
Step 3: Utilization and Grid Interconnection
At this point, the electricity produced is available for immediate consumption within your property. Simultaneously, any surplus electricity can be redirected to the grid, making it accessible for use by others. An energy meter allows tracking the amount of electricity imported from or exported to the grid.
Frequent questions about the installation of solar stations
Yes, solar panels in Spain are definitely worth it for several reasons. Firstly, Spain has a lot of sunlight, making it an ideal place to install solar panels. The installation of solar panels can significantly reduce or even eliminate your electricity bills while helping you reduce carbon emissions. Additionally, Spain offers attractive financial incentives such as subsidies, tax credits, and net metering programs for those who install solar panels. Finally, as energy costs continue to rise, investing in solar panels can provide an economically efficient and sustainable energy solution for your home or business. Given these advantages, it becomes clear that solar panels are a smart investment in Spain.
No, solar panels do not work at night because they rely on sunlight to generate electricity. Solar panels convert the energy of photons from sunlight into direct current (DC) electricity through a process called the photoelectric effect. At night, there is no sunlight available for the panels to convert into electricity. However, many households and businesses use battery storage systems to store excess energy generated during the day for use at night when there is no sunlight. This provides a continuous supply of electricity even when the solar panels are not actively producing energy. Additionally, some solar panels are equipped with technology that allows them to continue producing a small amount of electricity from moonlight.
Yes. When installed correctly, solar panels can generate enough electricity to supply the energy needs of a typical household in Spain. The system involves the installation of solar panels on the roof or ground, connected to an inverter that converts the generated power into usable AC electricity. The energy produced during the day can be used immediately to power appliances and lighting in the house, while any excess energy can be stored in batteries or sold back to the grid.
Fires can be caused by improper installation or damage that affects the safe operation of panels. However, it is important to know that solar panels today are designed to withstand harsh weather conditions, including heat, without catching fire. Some models are even equipped with safety features that help prevent fires, such as automatic shutdown in case of malfunction. To ensure uninterrupted operation of solar panels and reduce the risk of fire, it is essential to regularly perform technical maintenance by a qualified specialist.
You do need permission to install solar panels in Spain, but the type and level of permission may vary depending on the autonomous region, the type of installation (on-grid or off-grid), and the size and location of the panels. In general, you need to obtain planning permission (licencia de obras) from your local town hall, access and connection permission from your utility company, and registration of your installation with the regional energy authority.

| 2015-2018 | 4699-5467 | The “sun tax” slowed down the growth from 2015 to 2018. After it was removed, the sector boomed and reached its target. |
| 2019 | 10118 | About 500 000 households had solar panels in Spain. The solar energy sector experienced a boom, with a 94% increase in installed capacity compared to 2018. |
| 2020 | 14000 | About 650 000 households had solar panels in Spain. The solar energy sector was resilient to the COVID-19 pandemic, with a 30% increase in installed capacity compared to 2019. |
| 2021 | 18000 | About 800 000 households had solar panels in Spain. The solar energy sector continued to grow, with a 28% increase in installed capacity compared to 2020. |
| 2022 | 22000 | About 950 000 households had solar panels in Spain. The solar energy sector reached a new record, with a 22% increase in installed capacity compared to 2021. |
| 2023 | 26000 | About 1 100 000 households had solar panels in Spain. The solar energy sector achieved its target, with a 18% increase in installed capacity compared to 2022. |
Key facts:
