The location of Pasig-bo, Western Visayas, Philippines, situated at 11.096 latitude and 122.4584 longitude, presents a promising opportunity for solar energy generation throughout the year. Being in the tropics, this area benefits from consistent sunlight and experiences wet and dry seasons rather than traditional four-season cycles.

Seasonal Solar Output

Solar panel performance at this location varies across the meteorological seasons. Spring stands out as the most productive period, with an impressive daily output of 6.10 kWh per kW of installed solar capacity. Summer follows closely, generating 5.47 kWh/day, while autumn and winter produce 4.86 kWh/day and 4.26 kWh/day, respectively. These figures indicate that Pasig-bo maintains relatively high solar energy potential throughout the year, with only a moderate dip in production during the winter months. The consistent sunlight in this tropical region contributes to this stable energy output.

Optimal Panel Tilt

For fixed solar panel installations in Pasig-bo, Western Visayas, the ideal tilt angle to maximize year-round energy production is 9 degrees facing South. This slight tilt helps optimize the panels' exposure to sunlight throughout the year, taking into account the location's latitude and the sun's changing position in the sky.

Environmental Considerations

While Pasig-bo'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, it's crucial to use sturdy mounting systems and panels designed to withstand high winds. 2. Heavy rainfall: During the wet season, frequent rain can reduce solar panel efficiency. Installing panels at the optimal angle helps with water runoff, and using high-quality, water-resistant equipment is essential. 3. High humidity: The tropical climate's humidity can potentially lead to moisture buildup on panels. Regular cleaning and maintenance, along with proper sealing of electrical components, can help prevent issues related to humidity. By taking these factors into account and implementing appropriate preventative measures during installation, solar energy systems in Pasig-bo can achieve optimal performance and longevity. Overall, this location offers excellent potential for year-round solar energy generation, with spring and summer being particularly productive seasons.

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 Pasig-bo

Seasonal solar PV output for Latitude: 11.096, Longitude: 122.4584 (Pasig-bo, 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 Pasig-bo, Philippines

To maximize your solar PV system's energy output in Pasig-bo, Philippines (Lat/Long 11.096, 122.4584) 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 Pasig-bo, 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 Pasig-bo, 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	27° 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 Pasig-bo, 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 Pasig-bo, 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 Pasig-bo, Philippines

The topography around Pasig-bo, Philippines, located at approximately 11.096 degrees latitude and 122.4584 degrees longitude, is characterized by a diverse landscape typical of the Western Visayas region. This area is part of Panay Island, known for its varied terrain that includes coastal plains, rolling hills, and mountainous regions. Near Pasig-bo, the land is predominantly composed of gently sloping terrain and low-lying areas. As you move inland from the coast, the elevation gradually increases, giving way to more undulating hills and small valleys. The region is dotted with numerous rivers and streams that flow from the higher elevations towards the sea, creating fertile alluvial plains along their banks.

Suitable Areas for Large-scale Solar PV

When considering areas nearby that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would be relatively flat or gently sloping areas with good exposure to sunlight throughout the day. Based on the topography of the region, the following areas near Pasig-bo could be potential candidates: The coastal plains to the west and southwest of Pasig-bo offer expansive, flat terrain that could accommodate large solar arrays. These areas typically have fewer obstructions to block sunlight and are easily accessible for construction and maintenance. Some of the broader valley floors between the rolling hills inland from Pasig-bo might also be suitable. These areas often have good sun exposure and are protected from strong winds by the surrounding hills. The gently sloping hillsides facing south or southwest could be considered for solar installations. While not as ideal as flat land, these slopes can still provide excellent sun exposure and may be less valuable for agricultural purposes. It's important to note that while topography is a crucial factor, other considerations such as land ownership, proximity to power infrastructure, and environmental impact must also be taken into account when planning large-scale solar PV projects. Additionally, local weather patterns, particularly the frequency of typhoons in the region, would need to be carefully evaluated to ensure the long-term viability and safety of any solar installation.
