Palo, Eastern Visayas, Philippines, located at 11.1611°N, 124.9907°E, offers a promising environment for solar energy generation. Situated in the tropics, this location benefits from consistent sunlight throughout the year, with seasons primarily characterized by wet and dry periods rather than temperature variations.

Solar photovoltaic (PV) panels in Palo can produce substantial amounts of electricity year-round. The energy output varies across meteorological seasons, with spring being the most productive at 6.24 kWh per day for each kilowatt of installed solar capacity. Summer follows closely at 5.84 kWh/day, while autumn and winter see slightly lower outputs at 4.95 kWh/day and 4.19 kWh/day, respectively.

Optimal Panel Positioning

For fixed panel installations in Palo, Eastern Visayas, the ideal tilt angle to maximize year-round solar production is 9 degrees facing South. This angle ensures optimal exposure to sunlight throughout the year, taking into account the Earth's elliptical orbit and the location's latitude.

Seasonal Variations

The most favorable time for solar energy generation in Palo is during the spring months, followed closely by summer. While autumn and winter produce less energy, the difference is not as pronounced as in locations farther from the equator. This relatively consistent output makes Palo an excellent location for year-round solar energy production.

Environmental Considerations

Despite the generally favorable conditions, there are some environmental factors to consider when installing solar PV systems in Palo:

1. Typhoons: The Philippines is prone to typhoons, which can damage solar installations. To mitigate this risk, use sturdy mounting systems and panels designed to withstand high winds.
2. Heavy rainfall: During the wet season, frequent rain can reduce solar efficiency. Installing panels at the optimal angle helps with water runoff and reduces dust accumulation.

To maximize energy production and protect the solar installation, consider using typhoon-resistant mounting systems, high-quality waterproof components, and implementing a regular cleaning and maintenance schedule. These measures will help ensure consistent and efficient solar energy generation in Palo 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 Palo

Seasonal solar PV output for Latitude: 11.1611, Longitude: 124.9907 (Palo, 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 Palo, Philippines

To maximize your solar PV system's energy output in Palo, Philippines (Lat/Long 11.1611, 124.9907) 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 Palo, 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 Palo, 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	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 Palo, 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 Palo, 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 Palo, Philippines

The topography around Palo, Philippines, located at latitude 11.1611 and longitude 124.9907, is characterized by a diverse landscape that combines coastal lowlands, gently rolling hills, and more elevated terrain as you move inland. Situated on the eastern coast of Leyte Island, Palo is nestled between the Leyte Gulf to the east and the Cordillera Central mountain range to the west. The coastal areas of Palo feature relatively flat terrain with sandy beaches and some mangrove forests. As you move slightly inland, the landscape transitions into a mix of agricultural lands and low-lying plains. These areas are primarily used for rice cultivation and other crops, taking advantage of the fertile soil deposited by rivers flowing from the mountains. Further inland, the topography becomes more varied, with undulating hills and small valleys. These hills gradually increase in elevation as they approach the Cordillera Central, which forms the spine of Leyte Island. The slopes of these hills are often covered in tropical vegetation, including coconut plantations and patches of forest.

Potential Areas for Large-scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Palo, several factors come into play, including available land, sun exposure, and proximity to existing infrastructure. Based on the topography of the region, the following areas could be suitable for solar PV development: The coastal plains and low-lying areas just inland from Palo offer potential for solar farms. These relatively flat areas receive ample sunlight and have fewer obstructions that could cast shadows on solar panels. However, care must be taken to avoid areas prone to flooding or storm surges. The gently rolling hills to the west of Palo present another opportunity for solar PV installations. These elevated areas may benefit from increased sun exposure and reduced risk of flooding. The slopes of these hills, if not too steep, could be utilized for solar arrays, potentially maximizing energy generation throughout the day. Agricultural lands that are less productive or have been abandoned could be repurposed for solar energy production. This approach would need to balance the region's agricultural needs with renewable energy goals. It's important to note that while these areas may be topographically suitable, other factors such as land ownership, environmental considerations, and grid connectivity would need to be carefully evaluated before embarking on any large-scale solar PV project in the region.
