Solar PV Analysis of Reus, Spain
Located in Reus, Catalonia, Spain (latitude: 41.1548, longitude: 1.1212), the average daily solar energy production per kilowatt of installed solar capacity across all seasons is quite promising for photovoltaic power generation. During the summer months, each kilowatt produces an average of 7.34 kWh per day due to extended daylight hours and more direct sunlight exposure. In autumn, the daily yield decreases to an average of 3.75 kWh due to shorter days and lower sun intensity.
Winter sees a further reduction in yield with an average production of 2.42 kWh per day per kilowatt installed owing to shorter daylight hours and lower sun angles which reduce the amount of sunlight reaching the panels directly. However, as spring arrives with longer days and higher sun angles, there is a significant increase in solar energy production averaging at around 5.81 kWh per day for each installed kilowatt.
For optimal performance at this location, it's recommended that fixed panels are tilted at an angle of approximately 35 degrees facing southward for maximum exposure to sunlight throughout the year.
While Reus offers substantial potential for solar power generation given its seasonal averages, certain environmental factors could potentially impact productivity levels from time to time such as heavy rainfall or strong winds which may temporarily decrease panel efficiency by blocking sunlight or causing physical damage respectively.
To mitigate these risks during installation and ensure maximum energy output throughout their lifespan irrespective of weather conditions; sturdy mounting systems should be used that can withstand high wind speeds while also incorporating appropriate drainage solutions that prevent water accumulation on panel surfaces during periods of heavy rainfall thereby ensuring unimpeded access to direct sunlight whenever available.
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 Reus
Seasonal solar PV output for Latitude: 41.1548, Longitude: 1.1212 (Reus, 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 35° South in Reus, Spain
To maximize your solar PV system's energy output in Reus, Spain (Lat/Long 41.1548, 1.1212) throughout the year, you should tilt your panels at an angle of 35° 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 Reus, 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 Reus, Spain. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 25° South in Summer | 45° South in Autumn | 56° South in Winter | 34° 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 Reus, 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 Reus, 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 Reus, Spain
The topography around Reus, Spain is generally flat with some slight rolling hills. The nearby area that would be most suited to large-scale solar PV is the plains and valleys in the surrounding areas. These areas have plenty of open space and are usually free from any obstructions such as trees or buildings that could block sunlight from reaching the panels. Additionally, these plains and valleys tend to have good wind speeds which can help increase efficiency of the solar PV system.
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.
