Solar PV Analysis of Lagos, Portugal
Lagos, Faro, Portugal, situated at 37.1052° N latitude and -8.6713° E longitude, offers a promising location for solar PV energy generation throughout the year. This coastal town in the Algarve region benefits from its position in the Northern Temperate Zone, experiencing a Mediterranean climate with abundant sunshine.
Seasonal Solar Production
Solar energy production in Lagos varies significantly across seasons. Summer stands out as the most productive period, with an impressive 8.23 kWh per day for each kW of installed solar capacity. Spring follows closely, generating 6.70 kWh/day. Autumn sees a moderate decrease to 4.78 kWh/day, while winter experiences the lowest output at 2.82 kWh/day.
The substantial difference between summer and winter production highlights the region's distinct seasonal patterns. However, even during the least productive winter months, Lagos still maintains a respectable solar energy output, making it a viable location for year-round solar power generation.
Optimal Panel Installation
To maximize year-round solar energy production in Lagos, Faro, fixed solar panels should be tilted at a 32-degree angle facing south. This optimal angle ensures the panels capture the most sunlight throughout the year, accounting for the sun's changing position across seasons.
Environmental Considerations
While Lagos generally provides favorable conditions for solar energy production, there are a few environmental factors to consider:
- Coastal salt spray: Being close to the Atlantic Ocean, solar panels may be exposed to salt air, which can potentially corrode equipment over time.
- Occasional dust from Saharan winds: Lagos sometimes experiences dust carried by winds from the Sahara Desert, which can temporarily reduce panel efficiency.
To mitigate these issues, installers should use corrosion-resistant materials and implement regular cleaning schedules. Additionally, installing panels at the recommended angle helps with natural cleaning during rainfall, reducing dust accumulation.
Overall, Lagos presents an excellent location for solar PV installations, with its abundant sunshine and mild climate contributing to strong year-round energy production potential.
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 179 locations across Portugal. 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 Lagos
Seasonal solar PV output for Latitude: 37.1052, Longitude: -8.6713 (Lagos, Portugal), 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 32° South in Lagos, Portugal
To maximize your solar PV system's energy output in Lagos, Portugal (Lat/Long 37.1052, -8.6713) throughout the year, you should tilt your panels at an angle of 32° 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 Lagos, Portugal
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 Lagos, Portugal. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 21° 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 Lagos, Portugal
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 Lagos, Portugal.
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 Lagos, Portugal
Lagos, Portugal is situated in the Algarve region, known for its diverse and picturesque topography. The area around Lagos features a mix of coastal and inland landscapes that offer a variety of terrain types.
The coastline near Lagos is characterized by stunning cliffs, sandy beaches, and rocky outcrops. These dramatic coastal features give way to gently rolling hills as you move inland. The terrain gradually becomes more elevated, with some areas reaching heights of around 150-200 meters above sea level within a few kilometers of the coast.
To the north and northeast of Lagos, the landscape transitions into the foothills of the Monchique mountain range. This area is marked by more rugged terrain, with steeper slopes and deeper valleys. The vegetation becomes denser in these parts, with cork oak and eucalyptus trees being common sights.
For large-scale solar PV installations, the most suitable areas would likely be found inland, away from the immediate coastal zone. The gently rolling hills to the north and east of Lagos offer promising locations for solar farms. These areas typically have:
- More consistent exposure to sunlight throughout the day
- Less interference from coastal weather patterns like fog or sea mist
- Larger, flatter areas that can accommodate extensive solar panel arrays
- Fewer conflicts with prime tourism and residential zones
Specifically, the regions between Lagos and the towns of Bensafrim and Odiáxere might be well-suited for solar PV development. These areas feature expansive, open landscapes with good sun exposure and relatively flat terrain. Additionally, the slightly higher elevations in these parts can help minimize shading issues and maximize solar energy capture.
It's worth noting that while the Algarve region receives abundant sunshine, making it attractive for solar energy production, any large-scale development would need to carefully consider environmental impacts, local regulations, and grid connection capabilities. The region's natural beauty and ecological significance mean that thorough planning and environmental assessments would be crucial for any major solar PV project.
