Cotabato City, Autonomous Region in Muslim Mindanao, Philippines, located in the tropics, offers a promising environment for solar energy generation. This location experiences consistent sunlight throughout the year, with seasons primarily characterized by wet and dry periods rather than traditional four-season cycles.

Year-round Solar Energy Potential

The solar energy output at this location remains relatively stable across the meteorological seasons. Spring and summer show the highest potential, with 5.94 kWh/day and 5.92 kWh/day respectively per kW of installed solar capacity. Autumn follows with 5.37 kWh/day, while winter sees a slight dip to 4.92 kWh/day.

These figures indicate that Cotabato City maintains good solar energy generation potential throughout the year. The minimal variation between seasons suggests a reliable and consistent energy source, making it an attractive location for solar PV installations.

Optimal Panel Tilt Angle

For fixed panel installations in Cotabato City, Autonomous Region in Muslim Mindanao, the ideal tilt angle to maximize year-round solar production is 6 degrees South. This slight tilt helps optimize energy capture throughout the year, accounting for the location's proximity to the equator and the Earth's elliptical orbit.

Environmental and Weather Considerations

While Cotabato City's tropical climate is generally favorable for solar energy production, there are some factors to consider:

1. Rainfall: The region experiences a monsoon climate with significant rainfall, particularly from June to October. Heavy cloud cover during these months may temporarily reduce solar output.
2. Humidity: High humidity levels can potentially impact solar panel efficiency and longevity.

To mitigate these factors, consider the following preventative measures:

• Use high-quality, weather-resistant solar panels designed for tropical climates
• Implement proper drainage systems to prevent water accumulation on panels
• Regular cleaning and maintenance to remove dirt and moisture buildup
• Install panels at the optimal tilt angle to maximize sunlight exposure and facilitate natural cleaning during rainfall

Overall, Cotabato City presents a favorable location for solar PV installations, with consistent year-round energy potential and manageable environmental challenges.

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 257 locations across Philippines. 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 Cotabato City

Seasonal solar PV output for Latitude: 7.0356, Longitude: 124.3896 (Cotabato City, Philippines), 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 6° South in Cotabato City, Philippines

To maximize your solar PV system's energy output in Cotabato City, Philippines (Lat/Long 7.0356, 124.3896) throughout the year, you should tilt your panels at an angle of 6° 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 Cotabato City, Philippines

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 Cotabato City, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 6° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
9° North in Summer	13° South in Autumn	23° South in Winter	1° 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 Cotabato City, Philippines

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 Cotabato City, Philippines.

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 Cotabato City, Philippines

The topography around Cotabato City, Philippines, is characterized by a diverse landscape that includes coastal plains, river valleys, and rolling hills. Situated on the island of Mindanao, Cotabato City is nestled along the banks of the Rio Grande de Mindanao, one of the country's largest river systems. The city itself is primarily flat, with an elevation close to sea level, making it vulnerable to flooding during heavy rains and storm surges. As you move away from the city center, the terrain gradually becomes more varied. To the north and east, the land rises into gently rolling hills and low-lying mountains. These areas are often covered in lush vegetation, including tropical forests and agricultural lands. The southern and western parts of the region are dominated by the vast Liguasan Marsh, a complex network of wetlands, swamps, and ponds that plays a crucial role in the local ecosystem.

Potential Areas for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Cotabato City, several factors come into play. The ideal areas would have ample sunlight exposure, relatively flat terrain, and be easily accessible for construction and maintenance. The coastal plains to the southwest of Cotabato City offer promising potential for solar PV development. These areas typically have fewer obstructions to sunlight and provide large, open spaces that could accommodate extensive solar arrays. The relatively flat terrain would minimize the need for extensive land preparation, reducing installation costs. Another suitable location could be the gently sloping hills to the north and east of the city. While these areas may require some land preparation, they often receive excellent sun exposure throughout the day. Additionally, the slightly elevated position could help mitigate potential flooding risks that are more common in the lowland areas. It's important to note that any large-scale solar PV project would need to carefully consider environmental impacts, particularly in relation to the sensitive ecosystems of the Liguasan Marsh. Proper planning and environmental assessments would be crucial to ensure that renewable energy development does not come at the cost of biodiversity and ecological balance in the region. In conclusion, while the topography around Cotabato City presents some challenges, there are viable options for large-scale solar PV installations. The key lies in balancing the need for suitable terrain and sun exposure with environmental considerations and accessibility.
