David, Chiriquí Province, Panama, located at 8.4393° N, 82.4383° W, offers a promising environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than significant temperature variations.

Solar Energy Potential

The solar energy output in David is relatively stable across all seasons, with a slight increase during winter and spring. The average daily electricity output per kilowatt of installed solar capacity ranges from 4.70 kWh in summer to 5.49 kWh in spring. This consistency is advantageous for solar energy production, as it ensures a reliable power supply year-round. Winter and spring emerge as the most productive seasons for solar energy generation in David. During these months, the slightly higher solar output can be attributed to clearer skies and potentially less cloud cover. However, the difference in production between seasons is not dramatic, which speaks to the location's overall suitability for solar power throughout the year.

Optimal Panel Installation

For fixed solar panel installations in David, Chiriquí Province, the ideal tilt angle to maximize year-round production is 9 degrees facing South. This relatively low tilt angle is due to the location's proximity to the equator, where the sun's path is more directly overhead throughout the year.

Environmental Considerations

While David's tropical climate is generally favorable for solar energy production, there are some environmental factors to consider: 1. Rainfall: The wet season, typically from May to November, may lead to increased cloud cover and potentially reduced solar output. 2. Humidity: High humidity levels can slightly decrease panel efficiency and may contribute to faster degradation of equipment. To mitigate these factors, consider the following preventative measures:

• Use high-quality, weather-resistant solar panels designed for tropical climates
• Implement regular cleaning and maintenance schedules to prevent buildup of dust or organic matter
• Install panels at the optimal angle to maximize exposure and facilitate natural cleaning by rainfall
• Consider using microinverters or power optimizers to minimize the impact of partial shading on overall system performance

Overall, David, Chiriquí Province, Panama presents an excellent location for solar energy production, with consistent year-round output and only minor environmental challenges that can be effectively managed with proper planning and maintenance.

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 David

Seasonal solar PV output for Latitude: 8.4393, Longitude: -82.4383 (David, Panama), 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 9° South in David, Panama

To maximize your solar PV system's energy output in David, Panama (Lat/Long 8.4393, -82.4383) throughout the year, you should tilt your panels at an angle of 9° 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 David, Panama

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 David, Panama. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 9° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
8° North in Summer	14° South in Autumn	24° 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.

Calculate solar panel row spacing in David, Panama

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 David, Panama.

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 David, Panama

The area surrounding David, Panama, located at approximately 8.4393°N latitude and 82.4383°W longitude, presents a diverse and interesting topography. This region, situated in the western part of Panama, is characterized by a mix of lowlands, rolling hills, and mountainous terrain. Near the city of David itself, the landscape is predominantly flat to gently rolling, with elevations gradually increasing as one moves away from the coast. This coastal plain, known as the Chiriquí lowlands, extends for several kilometers inland before transitioning into more varied terrain. The soil in this area is generally fertile, supporting agricultural activities and providing a stable foundation for infrastructure development. As you move further inland and to the north of David, the topography becomes more pronounced. The terrain begins to undulate more significantly, with hills and small valleys creating a picturesque landscape. This area marks the transition between the coastal lowlands and the mountainous regions that dominate much of Panama's interior.

Mountainous Regions

To the north and east of David, the landscape becomes increasingly mountainous. The Cordillera Central, a major mountain range that runs through Panama, rises dramatically in this area. These mountains, part of the Talamanca Range, feature steep slopes, deep valleys, and peaks that reach heights of over 3,000 meters (9,800 feet) above sea level. The most prominent peak in this region is Volcán Barú, Panama's highest point, which stands at 3,475 meters (11,401 feet) and is visible from David on clear days.

Potential for Solar PV Development

When considering areas suitable for large-scale solar photovoltaic (PV) installations near David, several factors come into play. The most promising locations would likely be found in the relatively flat areas of the Chiriquí lowlands, extending from the outskirts of David towards the coast. These areas offer several advantages for solar PV development: Firstly, the flat terrain reduces the need for extensive land preparation and allows for easier installation and maintenance of solar panels. The open nature of these lowlands also minimizes shading issues that can reduce the efficiency of solar arrays. Secondly, proximity to David provides easier access to existing infrastructure, including roads and electrical grid connections, which are crucial for the construction and operation of large-scale solar facilities. Lastly, the region's climate, characterized by abundant sunshine throughout much of the year, makes it well-suited for solar energy production. However, it's important to note that while the lowlands offer the most practical locations for solar PV, careful environmental assessments would be necessary to ensure that such developments do not negatively impact local ecosystems or agricultural lands. While the mountainous areas to the north and east of David receive ample sunlight, their steep slopes and rugged terrain make them less suitable for large-scale solar installations. These areas would present significant challenges in terms of construction, maintenance, and grid connection, making them less economically viable for solar PV development compared to the more accessible lowland regions.
