Solar PV Analysis of Arona, Spain
Located at latitude 28.0485 and longitude -16.6611, Arona, Canary Islands, Spain is an optimal location for harnessing solar energy due to its year-round sunlight exposure. The city's average daily kilowatt-hours (kWh) produced per kilowatt (kW) of installed solar capacity varies across the seasons: it stands at 7.08 in summer, reduces to 5.14 in autumn, further drops to 4.14 in winter before rising again to 6.77 in spring.
The high figures during the summer months can be attributed to longer daylight hours and increased intensity of sunlight which maximize the photovoltaic power generation potential of solar installations.
A fixed panel installation at this location should ideally be tilted at an angle of 25 degrees towards the south for optimum energy production throughout the year.
Despite these promising figures, there are environmental factors that could potentially hinder optimal solar production in Arona such as periodic rainfall or occasional snowfall which could obscure sunlight and reduce energy generation from photovoltaic systems.
To mitigate these potential impediments, it would be prudent when installing solar panels to ensure they have a clear line-of-sight towards the sky without any obstructions that might block direct sunlight exposure such as tall buildings or trees nearby.
Moreover, incorporating a system for cleaning and maintaining panels will help keep them free from dust or snow accumulation which could otherwise degrade their performance over time.
In summary, while Arona's geographical position makes it well-suited for generating substantial amounts of solar power throughout most parts of the year; careful planning around installation site selection and regular maintenance can help ensure consistent high levels of energy production despite occasional adverse weather conditions.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° 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 Arona
Seasonal solar PV output for Latitude: 28.0485, Longitude: -16.6611 (Arona, 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 25° South in Arona, Spain
To maximize your solar PV system's energy output in Arona, Spain (Lat/Long 28.0485, -16.6611) throughout the year, you should tilt your panels at an angle of 25° 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 Arona, 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 Arona, Spain. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 25° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 12° South in Summer | 33° South in Autumn | 43° South in Winter | 21° 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 Arona, 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 Arona, 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 Arona, Spain
The topography around Arona, Spain is generally flat and low-lying. Areas to the south of the town are particularly suitable for large-scale solar PV installations due to their proximity to the coast and relatively high levels of sunlight. The nearby towns of Los Cristianos and Las Americas also provide good sites for solar PV systems due to their open spaces and clear skies. Further inland, areas such as El Médano may also be suitable locations for large-scale solar PV projects.
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.
