San Francisco, Zulia, Venezuela, located in the tropics at 10.8221° N, 71.2726° W, offers a favorable environment for solar energy production throughout the year. This location benefits from consistent sunlight and experiences wet and dry seasons rather than traditional four-season cycles.
Solar Energy Production Potential
The solar energy output at this location remains relatively stable across all seasons, with only minor fluctuations. Winter sees the highest production at 6.34 kWh per day per kW of installed solar capacity, followed closely by spring at 6.05 kWh/day, summer at 6.01 kWh/day, and autumn at 5.75 kWh/day. This consistent output throughout the year makes San Francisco, Zulia, Venezuela, an ideal location for solar PV installations. The minimal variation between seasons ensures a reliable energy supply, reducing the need for supplementary power sources during less productive periods.Optimal Panel Tilt Angle
For fixed panel installations in this location, the ideal tilt angle to maximize year-round solar production is 11 degrees facing South. This angle has been calculated considering daily solar elevation angles, optimal panel tilt, and weighted by daily PV potential using NASA's solar irradiance data.Environmental and Weather Considerations
While San Francisco, Zulia, Venezuela, offers excellent conditions for solar energy production, there are some environmental factors to consider: 1. High humidity: The tropical climate can lead to increased moisture, potentially affecting solar panel efficiency and lifespan. 2. Heavy rainfall: During the wet season, frequent rain may temporarily reduce solar output. To mitigate these factors, the following preventative measures can be taken:- Use corrosion-resistant materials for mounting systems and electrical components
- Install panels at the optimal angle to promote water runoff
- Implement regular cleaning and maintenance schedules to prevent dirt and debris accumulation
- Consider using hydrophobic coatings on panels to improve water resistance
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 83 locations across Venezuela. 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 San Francisco
Seasonal solar PV output for Latitude: 10.8221, Longitude: -71.2726 (San Francisco, Venezuela), 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 11° South in San Francisco, Venezuela
To maximize your solar PV system's energy output in San Francisco, Venezuela (Lat/Long 10.8221, -71.2726) throughout the year, you should tilt your panels at an angle of 11° 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 San Francisco, Venezuela
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 San Francisco, Venezuela. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 11° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 5° North in Summer | 17° South in Autumn | 26° South in Winter | 5° 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 San Francisco, Venezuela
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 San Francisco, Venezuela.
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 San Francisco, Venezuela
San Francisco, Venezuela, is situated in a region characterized by diverse topography. The area surrounding this location features a mix of coastal plains, rolling hills, and rugged mountains. To the west, the landscape gradually slopes down towards the shores of Lake Maracaibo, a large brackish bay connected to the Caribbean Sea. The eastern side of San Francisco is marked by the foothills of the Andes Mountains, which begin to rise more dramatically as one moves further inland. The immediate vicinity of San Francisco consists primarily of gently undulating terrain, with occasional small hills and shallow valleys. This area is part of the broader Maracaibo Basin, a geological depression that encompasses Lake Maracaibo and its surrounding lowlands. The soil in this region is generally fertile, supporting various agricultural activities.
Potential for Solar PV Development
When considering areas suitable for large-scale solar photovoltaic (PV) installations near San Francisco, several factors come into play. The most promising locations would be the relatively flat, open areas to the north and east of the city. These regions offer expansive tracts of land with minimal shading from natural features, which is crucial for maximizing solar energy capture. The gently rolling plains that extend eastward from San Francisco provide an ideal setting for solar farms. These areas receive ample sunlight throughout the year due to their proximity to the equator, and the lack of significant geographical obstacles ensures consistent exposure to solar radiation. Additionally, the stable ground conditions in these plains make it easier and more cost-effective to install and maintain large arrays of solar panels. Another potentially suitable area for solar PV development lies to the northwest of San Francisco, in the transitional zone between the coastal plains and the foothills. This region offers a good balance of flat terrain and slightly elevated areas, which can be advantageous for solar panel placement and natural air circulation, helping to keep the panels cool and efficient. It's worth noting that while the mountainous areas to the far east might seem attractive due to their elevation, they are generally less suitable for large-scale solar installations. The rugged terrain and potential shading from peaks and ridges can complicate construction and reduce overall energy production efficiency. In conclusion, the areas most suited to large-scale solar PV near San Francisco, Venezuela, are the open plains to the east and the transitional zones to the northwest. These regions offer the right combination of flat terrain, consistent sunlight exposure, and accessibility necessary for successful solar energy projects.Citation Guide
