Solar Panels Southern Spain FAQ | Your Questions Answered

Southern Spain is one of Europe’s sunniest regions, with Almería and surrounding areas receiving around 3,000+ hours of sunshine per year. A typical 5 kWp system here can generate 7,000–8,500 kWh annually — significantly more than the same system in northern Europe.

For most residential installations you’ll need a municipal building licence (licencia de obras) and, once installed, you must register with your autonomous community’s energy registry (REES) and notify the electricity distributor. Here at Go Solar we handle all paperwork on your behalf.

Yes. Since 2021, Spain’s ‘autoconsumo colectivo’ regulations allow you to feed surplus electricity into the grid and receive a credit on your electricity bill (compensación simplificada). The rate is set by your energy supplier and varies, but it’s a straightforward way to offset costs.

Yes. The Spanish government and the Junta de Andalucía periodically offer grants through programmes such as Plan MOVES III and European Recovery Fund initiatives, which can cover 15–40% of installation costs.

System size depends on two factors. Firstly your annual electricity consumption and secondly your available roof space. A typical family home in southern Spain uses around 4,000–6,000 kWh per year, and a 3–6 kWp system will usually cover most of that. We carry out a free on-site assessment to recommend the right size for you. If you would like us to come and take a look and provide a quote give me a call: +34 654 59 62 47

Batteries are optional but increasingly popular. Without storage, surplus energy is exported to the grid (with compensation). With storage, you can use your own solar energy at night and during cloudy periods, increasing self-consumption to 70–90%. We’ll model both scenarios for you. Take a look at our Virtual Battery page for more information.

For a standard residential installation, the physical work typically takes 1, sometimes 2 days. We also submit permit applications and grid connection paperwork.

In southern Spain, most residential systems pay for themselves in 5–8 years, depending on system size, energy consumption, and grid tariff. With a system lifespan of 25–30 years, you can expect 17–25 years of near-free electricity. And before that – guilt free use of air con and heating.

Yes — panels generate electricity from daylight, not direct sunlight, so they still produce on overcast days (though output is reduced). Interestingly, panels are most efficient at cooler temperatures; the intense summer heat of Andalusia can reduce peak output slightly, but longer days more than compensate.

Very little. Panels are self-cleaning to a large extent, though in dusty areas like Almería it helps to rinse them a few times a year. Most quality panels carry a 25-year performance warranty and a 10–12 year product warranty.

We install on all roof types — pitched clay or concrete tile, flat concrete, metal, and SIPS panels. Flat roofs use adjustable mounting frames angled for optimal sun exposure. We conduct a structural survey before installation to ensure the roof can support the panels safely. Some roofs are just not suitable due to the orientation or the complex angles. We will let you know. There might be other options you wish to consider, like a bespoke Solar Pergola or a Solar Car Port.

Yes, you should notify your insurer so the system is covered under your policy. Most standard home insurance policies in Spain will extend to cover solar panels, though some insurers require a specific rider. We can provide documentation for your insurer upon completion.

The average useful life of a solar panel is about 25 years at above a 81% production. This long useful life together with the fact that the maintenance of the installation is very simple makes the return on investment of solar energy compelling.

This depends on the type of installation and therefore the initial investment made, and how much electricity is used. If we talk about installations connected to the grid, which is the most widespread type of solar installation in homes in our country, it can be amortized in a period between 2 and 5 years.

Yes, it is possible to expand a solar installation. Before carrying out the expansion, we can do a site visit to verify that the rest of the equipment in the installation can support a greater power of solar generation.
