Acarigua, Portuguesa, Venezuela represents an excellent location for year-round solar photovoltaic energy generation. Located in the tropics at coordinates 9.5568°N, -69.2009°W, this area benefits from consistent sunlight throughout most of the year, with seasons characterized more by wet and dry periods rather than traditional temperature variations.

Solar Energy Production Potential

The solar energy output data for Acarigua demonstrates strong and consistent performance across all seasons. Winter emerges as the peak production period, generating 5.73 kWh per day per kW of installed solar capacity. Autumn follows closely with 5.66 kWh/day per kW, while Spring produces 5.33 kWh/day per kW, and Summer yields 5.09 kWh/day per kW. This seasonal pattern is typical for tropical locations, where the sun's position relative to the earth during winter months actually provides more direct solar radiation to areas near the equator. The relatively small variation between seasons (only 0.64 kWh difference between the highest and lowest producing seasons) makes Acarigua particularly attractive for solar installations, as energy production remains reliable year-round. For fixed panel installations at this location, the ideal tilt angle is 10 degrees facing South. This angle maximizes total year-round solar production by optimizing the panels' exposure to the sun's path throughout the annual cycle.

Environmental and Weather Challenges

Several environmental factors could potentially impact solar energy production in Acarigua and require careful consideration during installation planning. The tropical climate brings intense rainfall during wet seasons, which can create challenges for solar installations. Heavy rains may cause temporary reductions in energy output due to cloud cover, and the accumulation of debris, leaves, and sediment on panels can significantly reduce their efficiency. Additionally, high humidity levels common in tropical regions can accelerate corrosion of metal components and electrical connections. Dust accumulation presents another significant challenge, particularly during dry seasons when fine particles can settle on panel surfaces and create a film that blocks sunlight. In agricultural areas surrounding Acarigua, Portuguesa, airborne particles from farming activities may compound this issue. The intense tropical sun, while beneficial for energy production, can also cause thermal stress on solar equipment. High temperatures may reduce panel efficiency and accelerate the degradation of system components over time.

Preventative Measures for Optimal Performance

Several installation strategies can help mitigate these environmental challenges and ensure maximum energy production:

• Install panels with adequate spacing and ventilation underneath to promote air circulation and reduce heat buildup
• Use corrosion-resistant mounting materials such as aluminum or stainless steel specifically rated for tropical marine environments
• Apply protective coatings to electrical connections and use weatherproof enclosures for inverters and other sensitive equipment
• Design drainage systems that quickly channel rainwater away from panel surfaces and mounting structures
• Install panels at sufficient height and angle to promote self-cleaning during rainfall

Regular maintenance becomes particularly important in this environment. Establishing a routine cleaning schedule, especially during dry periods, will help maintain optimal panel efficiency. Monitoring systems can alert operators to performance drops that may indicate cleaning or maintenance needs. Professional installation with proper grounding and surge protection is essential, given the potential for intense tropical storms and lightning activity. Quality inverters with high temperature ratings will perform better in the consistently warm climate. Despite these considerations, Acarigua's strong and consistent solar resource makes it an ideal location for solar PV installations when proper planning and maintenance practices are implemented.

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 Acarigua

Seasonal solar PV output for Latitude: 9.5568, Longitude: -69.2009 (Acarigua, 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 10° South in Acarigua, Venezuela

To maximize your solar PV system's energy output in Acarigua, Venezuela (Lat/Long 9.5568, -69.2009) throughout the year, you should tilt your panels at an angle of 10° 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 Acarigua, 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 Acarigua, Venezuela. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 10° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
6° North in Summer	15° South in Autumn	25° South in Winter	3° 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.

   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 Acarigua, Venezuela

Topographical Features of Acarigua

Acarigua sits in the heart of Venezuela's Portuguesa state, positioned within the expansive Llanos region that characterizes much of the country's central plains. The city itself rests at a relatively modest elevation of approximately 200 meters above sea level, surrounded by gently rolling terrain that gradually transitions from the foothills of the Andes Mountains to the east toward the vast flatlands that stretch northward to the Orinoco River basin. The immediate landscape around Acarigua consists primarily of undulating plains with gentle slopes and broad valleys. These plains are part of the larger Llanos ecosystem, characterized by grasslands interspersed with gallery forests along waterways and scattered patches of deciduous woodland. The terrain exhibits minimal elevation changes across large areas, with most variations being subtle rises and depressions rather than dramatic hills or valleys. To the south and southeast of Acarigua, the topography begins to show more pronounced changes as the land gradually rises toward the Andean foothills. This transition zone features more varied elevation patterns, with rolling hills becoming increasingly common as one moves away from the central plains. The northern and western areas maintain the characteristic flat to gently undulating profile typical of the Llanos region.

Water Features and Drainage

The region's hydrology is dominated by several important river systems that flow generally northward toward the Orinoco. The Portuguesa River, along with numerous tributaries and seasonal streams, creates a network of waterways that influence the local topography through their floodplains and associated wetland areas. These river corridors often feature slightly lower elevations and can experience seasonal flooding during the wet season, creating temporary wetland conditions in adjacent low-lying areas. Many of these waterways meander across the landscape, creating natural boundaries and influencing soil composition in their vicinity. The presence of these water features also supports ribbons of gallery forest that contrast with the more open grassland areas typical of the broader region.

Optimal Areas for Large-Scale Solar Development

The most promising locations for large-scale solar photovoltaic installations around Acarigua would be the extensive flat to gently rolling plains that dominate the northern and western portions of the area. These locations offer several topographical advantages, including minimal grading requirements, consistent solar exposure without significant shading from terrain features, and relatively uniform slopes that facilitate efficient panel installation and maintenance access. Areas situated on the broad interfluves between major waterways would be particularly well-suited for solar development. These elevated plains provide good drainage while avoiding the seasonal flooding risks associated with river corridors and their associated floodplains. The gentle, consistent slopes in these areas also minimize the need for extensive earthwork while ensuring adequate drainage for solar installations. The transitional zone to the southeast, while featuring more varied topography, could also accommodate solar projects on selected sites where south-facing slopes provide optimal panel orientation. However, the increased terrain complexity in these areas would likely require more careful site selection and potentially higher development costs compared to the flatter northern and western zones. Areas to avoid for large-scale solar development would include the immediate floodplains of major rivers, seasonal wetland zones, and the steeper terrain found in the far southeastern portions of the region where the Andean foothills begin to exert more influence on the landscape.
