Solar PV Analysis of Arteixo, Spain
Arteixo, Galicia, Spain is a favorable location for solar PV installations due to its geographical position and weather conditions. During the summer season, one can expect an average of 6.38 kWh per day for each kW of installed solar capacity. This figure slightly reduces to 5.61 kWh/day in spring due to the change in sun's position and daylight hours but still remains substantial.
In autumn, the daily yield decreases further to 3.48 kWh/day as a result of shorter daylight hours and less direct sunlight exposure on the panels while winter sees the lowest average production at 1.92 kWh/day owing to limited sunlight availability and lower temperatures that can affect panel efficiency.
Despite being situated in Northern Temperate Zone, Arteixo enjoys ample sunny days throughout most parts of the year with occasional spells of rain or snow which could potentially impact power generation from solar PV systems temporarily.
The ideal angle for fixed panel installation at this location is tilted towards 37 degrees South which ensures optimal exposure to sunlight year-round without requiring tracking systems. However, it's important during installation process to consider potential obstructions like buildings or trees that might cast shadows on panels thereby reducing their output.
Furthermore, local environmental factors such as dust accumulation on panels or bird droppings may also decrease efficiency over time but can be mitigated through regular cleaning and maintenance routines ensuring maximum energy production from your solar PV system in Arteixo all year round.
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 Arteixo
Seasonal solar PV output for Latitude: 43.3369, Longitude: -8.4669 (Arteixo, 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 37° South in Arteixo, Spain
To maximize your solar PV system's energy output in Arteixo, Spain (Lat/Long 43.3369, -8.4669) throughout the year, you should tilt your panels at an angle of 37° 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 Arteixo, 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 Arteixo, Spain. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 27° South in Summer | 47° South in Autumn | 58° South in Winter | 36° 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 Arteixo, 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 Arteixo, 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 Arteixo, Spain
The topography around Arteixo, Spain is generally flat with some rolling hills. Areas that are most suited to large-scale solar PV installations would be those that have the highest exposure to direct sunlight and minimal cloud cover. This includes areas with open fields, clear skies, and minimal obstructions such as trees or buildings. Areas near the coast may also be suitable due to their higher levels of sunshine and lower wind speeds.
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.
