Palompon, Eastern Visayas, Philippines, situated at 11.0432° N, 124.3852° E, offers a promising location for solar energy generation due to its tropical climate and consistent sunlight throughout the year. This coastal town in Leyte province experiences relatively stable solar conditions, making it suitable for year-round solar photovoltaic (PV) energy production.

Seasonal Solar Output

The expected electricity output per kilowatt of installed solar capacity varies across the meteorological seasons: Spring sees the highest production at 6.21 kWh/day, followed closely by Summer at 5.81 kWh/day. Autumn experiences a slight decrease to 4.96 kWh/day, while Winter has the lowest output at 4.23 kWh/day. These figures indicate that Palompon maintains good solar potential throughout the year, with only moderate fluctuations between seasons.

Optimal Panel Tilt

For fixed solar panel installations in Palompon, Eastern Visayas, the ideal tilt angle to maximize year-round energy production is 9 degrees facing South. This relatively shallow angle reflects the location's proximity to the equator, where the sun's path remains high in the sky throughout the year.

Peak Generation Periods

The most productive periods for solar energy generation in Palompon are during Spring and Summer. These seasons typically experience clearer skies and longer daylight hours, contributing to higher solar irradiance and, consequently, increased energy output.

Environmental Considerations

While Palompon's location is generally favorable for solar energy production, there are some environmental factors to consider: 1. Typhoons: The Philippines is prone to tropical cyclones, which can potentially damage solar installations. To mitigate this risk, robust mounting systems and high-quality, weather-resistant panels should be used. 2. Humidity: The tropical climate brings high humidity levels, which can lead to accelerated degradation of solar equipment. Choosing corrosion-resistant materials and ensuring proper sealing of electrical components can help prevent moisture-related issues. 3. Cloud cover: During the wet season, increased cloud cover may temporarily reduce solar output. Implementing a hybrid system with battery storage can help maintain consistent energy supply during cloudy periods. By addressing these factors through appropriate design and installation practices, Palompon can effectively harness its solar potential and benefit from clean, renewable energy throughout the year.

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 268 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 Palompon

Seasonal solar PV output for Latitude: 11.0432, Longitude: 124.3852 (Palompon, 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 9° South in Palompon, Philippines

To maximize your solar PV system's energy output in Palompon, Philippines (Lat/Long 11.0432, 124.3852) 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 Palompon, 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 Palompon, Philippines. 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
5° North in Summer	17° South in Autumn	26° South in Winter	4° 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 Palompon, 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 Palompon, 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 Palompon, Philippines

The topography around Palompon, Philippines, is characterized by a diverse landscape that includes both coastal and inland features. Palompon itself is situated on the western coast of Leyte Island, facing the Visayan Sea. The immediate coastal area is relatively flat, with sandy beaches and some low-lying areas that may be prone to flooding during storms or high tides.

As you move inland from the coast, the terrain gradually becomes more varied. The landscape transitions into gently rolling hills and small valleys, with elevations generally increasing as you progress eastward. These hills are often covered in a mix of grasslands, agricultural fields, and patches of tropical vegetation. In some areas, you might find small streams and rivers cutting through the terrain, creating natural drainage systems that flow towards the coast.

Further inland, especially towards the eastern part of Leyte Island, the topography becomes more rugged and mountainous. While these higher elevations are not in the immediate vicinity of Palompon, they do influence the overall geography and climate of the region.

Areas Suitable for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would have the following characteristics:

1. Flat or gently sloping terrain: The areas just inland from the coast, where the land begins to rise into rolling hills, could be suitable. These locations offer a good balance between flat surfaces for easy installation and slight elevations that may reduce the risk of flooding.

2. Open spaces with minimal shading: Agricultural lands or grasslands that are not heavily forested would be ideal. These areas receive maximum sunlight throughout the day, which is crucial for solar energy production.

3. Proximity to existing infrastructure: Locations near roads and power lines would be preferable, as this reduces the cost of transporting materials and connecting to the electrical grid.

4. Away from flood-prone areas: While the coastal regions might seem appealing due to their flatness, it's important to choose sites that are not at high risk of flooding or storm surges.

5. Respectful of local land use: Areas that are not prime agricultural land or ecologically sensitive would be more suitable to avoid conflicts with food production or environmental conservation efforts.

Given these considerations, the most promising areas for large-scale solar PV installations would likely be found in the gently sloping terrain just inland from Palompon, where there's a good balance of open space, suitable topography, and access to infrastructure, while also being at a safe distance from coastal hazards.
