Espargos, located in Cabo Verde, offers a promising location for solar energy generation due to its tropical climate and consistent sunlight throughout the year. This location, situated at 16.7524° N latitude and 22.942° W longitude, experiences relatively stable solar output across all seasons.

Seasonal Solar Performance

The solar energy production in Espargos demonstrates a favorable pattern throughout the year. Spring stands out as the most productive season, with an impressive daily output of 7.19 kWh per kW of installed solar capacity. Summer follows closely, generating 6.45 kWh per day. Even during the less productive seasons, the output remains substantial, with autumn and winter producing 5.66 kWh and 5.30 kWh per day, respectively.

Optimal Panel Installation

For those considering a fixed panel installation in Espargos, the ideal tilt angle to maximize year-round solar production is 15 degrees facing South. This angle has been calculated taking into account the location's latitude, daily solar elevation angles, and Earth's elliptical orbit, ensuring optimal exposure to sunlight throughout the year.

Peak Production Periods

The most favorable times for solar energy generation in Espargos are during the spring and summer months. These seasons offer longer daylight hours and more direct sunlight, resulting in higher energy output. However, it's worth noting that even during the less productive autumn and winter months, the solar output remains relatively high due to the location's tropical climate.

Environmental Considerations

While Espargos presents an overall ideal location for solar energy production, there are a few environmental factors to consider: 1. Dust and sand: Given Cabo Verde's proximity to the Sahara Desert, dust and sand can accumulate on solar panels, potentially reducing their efficiency. 2. Salt spray: Being an island location, salt spray from the ocean can build up on panels over time. To mitigate these issues, regular cleaning and maintenance of the solar panels is crucial. Installing panels at a slight angle (as recommended) can help with natural cleaning during rainfall. Additionally, using protective coatings on the panels can help resist salt and dust accumulation. In conclusion, Espargos, Cabo Verde, presents a highly favorable location for solar energy production throughout the year. With proper installation and maintenance, solar PV systems in this area can expect consistent and substantial energy output across all seasons.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Solar output per kW of installed solar PV by season in Espargos

Seasonal solar PV output for Latitude: 16.7524, Longitude: -22.942 (Espargos, Cabo Verde), 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 15° South in Espargos, Cabo Verde

To maximize your solar PV system's energy output in Espargos, Cabo Verde (Lat/Long 16.7524, -22.942) throughout the year, you should tilt your panels at an angle of 15° 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 Espargos, Cabo Verde

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 Espargos, Cabo Verde. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 15° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
1° South in Summer	22° South in Autumn	32° South in Winter	10° 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 Espargos, Cabo Verde

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 Espargos, Cabo Verde.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Espargos, Cabo Verde

The topography around Espargos, Cabo Verde, is characterized by a mix of flat and gently rolling terrain. Espargos is located on the island of Sal, which is known for its relatively flat landscape compared to other islands in the Cape Verde archipelago. The area surrounding Espargos features low-lying plains with occasional small hills and rocky outcrops. The island of Sal is predominantly arid and desert-like, with sparse vegetation and limited natural water sources. The terrain is mostly composed of sandy and rocky surfaces, with some areas of volcanic origin. The coastline near Espargos is marked by stretches of sandy beaches interspersed with rocky shorelines.

Suitability for Large-Scale Solar PV

The areas surrounding Espargos are particularly well-suited for large-scale solar photovoltaic (PV) installations due to several favorable factors. The flat and gently sloping terrain provides ideal conditions for the construction and placement of solar panels, minimizing the need for extensive land preparation or terracing. The region experiences abundant sunshine throughout the year, with very few cloudy days, making it an excellent location for solar energy generation. The lack of tall vegetation or geographical features that could cast shadows on solar arrays further enhances the area's suitability for solar PV projects. Some of the most promising areas for large-scale solar PV installations near Espargos include: 1. The expansive plains to the east and southeast of the town, where large, unobstructed areas of flat land are available. 2. The slightly elevated areas to the north and northwest of Espargos, which offer good exposure to sunlight and minimal interference from urban development. 3. The coastal regions to the west and southwest, where the combination of flat terrain and reflective properties of nearby water bodies could potentially enhance solar energy capture. It's worth noting that while the entire island of Sal presents favorable conditions for solar PV, areas closer to existing infrastructure and power distribution networks would be more practical for large-scale installations. Additionally, care should be taken to avoid ecologically sensitive areas or locations of cultural significance when planning such projects.
