Solar PV Analysis of Estepona, Spain
Estepona, Andalusia, Spain, is a good location for generating solar energy all year round. However, the amount of electricity produced varies with the seasons due to changes in sunlight intensity and duration.
In simple terms, you can expect the highest energy production during summer with an average of 8.28 kilowatt-hours per day for each kilowatt of installed solar power. Spring also has relatively high production rates at 6.34 kWh/day per kW of installed solar power.
On the other hand, autumn and winter see lower outputs due to shorter daylight hours and lower sun intensity; you can expect about 4.71 kWh/day in autumn and only about 2.99 kWh/day in winter per kW of installed solar power.
To maximize your total yearly output from a fixed panel installation at this location, it's recommended that panels are tilted at an angle of 31 degrees facing South.
As for potential local factors that could interfere with solar production here: Estepona is generally sunny but does experience some rain throughout the year which could temporarily reduce output during rainy periods or if panels get dirty from dust or debris carried by rainwater or wind.
One way to minimize this impact is by installing automated cleaning systems on your panels or scheduling regular manual cleanings to keep them clear from any dust or debris that might block sunlight.
Additionally, Estepona's coastal location means it can be subject to salty sea air which may cause corrosion over time on exposed metal parts of your PV system like mounting structures and connectors; using corrosion-resistant materials when installing your system can help prevent this issue.
Lastly, while Estepona doesn't have many tall buildings that could cast shadows on your panels (which would reduce their output), it's still important when choosing where exactly to install them that they're not shaded by nearby trees or other obstacles - especially around midday when the sun is highest in the sky as this is when they'll generate the most energy.
In conclusion, while there are some potential local factors to consider, none of them are significant enough to make Estepona a poor location for solar PV - especially if you take preventative measures like regular cleaning and using corrosion-resistant materials.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 361 locations across Spain. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Estepona
Seasonal solar PV output for Latitude: 36.4238, Longitude: -5.1443 (Estepona, Spain), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 31° South in Estepona, Spain
To maximize your solar PV system's energy output in Estepona, Spain (Lat/Long 36.4238, -5.1443) throughout the year, you should tilt your panels at an angle of 31° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Estepona, Spain
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Estepona, Spain. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 31° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 20° South in Summer | 41° South in Autumn | 52° South in Winter | 29° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Estepona, Spain
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Estepona, Spain.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Estepona, Spain
Estepona, Spain is located in the Costa del Sol region and is characterized by a mix of coastal plains and mountainous terrain. The town itself is relatively flat but it quickly gives way to the Sierra Bermeja mountains to the north. The region has a Mediterranean climate with hot summers and mild winters, making it suitable for solar power generation.
For large-scale solar PV installations, flat or gently sloping areas are generally preferred as they offer easier installation and maintenance. Therefore, while the mountainous regions might receive good sunlight, their steep slopes may not be ideal for large-scale installations.
The coastal plains around Estepona would likely be more suitable for such projects due to their flatter topography. However, land availability may be an issue given that these areas are often populated or used for agriculture.
In terms of sunlight exposure (which is crucial for solar power), Estepona has high solar irradiance levels due to its southern location and sunny climate. This makes it well-suited for solar energy production overall.
However, a more detailed site-specific assessment would need to be carried out considering factors such as local planning regulations, grid connectivity options, environmental impact assessments etc., before deciding on specific locations for large scale solar PV projects in or around Estepona.
Spain solar PV Stats as a country
Spain ranks 10th in the world for cumulative solar PV capacity, with 15,952 total MW's of solar PV installed. This means that 9.00% of Spain's total energy as a country comes from solar PV (that's 6th in the world). Each year Spain is generating 237 Watts from solar PV per capita (Spain ranks 20th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Spain?
Yes, there are several incentives for businesses wanting to install solar energy in Spain. These include the following:
1. The Spanish government offers a feed-in tariff (FIT) for businesses that install solar energy systems. This FIT guarantees a fixed price per kWh of electricity generated by the system over a period of 20 years.
2. Businesses can also benefit from tax deductions and other financial incentives when installing solar energy systems in Spain.
3. Companies may be eligible for grants or subsidies from regional governments or local authorities to help cover the cost of installation and maintenance of their solar energy systems.
4. Businesses may also be able to take advantage of net metering, which allows them to sell excess electricity generated by their solar energy system back into the grid at market prices, thus reducing their overall electricity costs even further.
