Bagong Silang, Calabarzon, Philippines, situated in the tropics, offers a promising location for solar PV energy generation throughout the year. This area experiences consistent sunlight and is characterized by wet and dry seasons rather than traditional four-season cycles.

Seasonal Solar Output

The solar energy production in Bagong Silang demonstrates relatively stable output across seasons, with a notable peak in spring. The average daily electricity output per kW of installed solar capacity is as follows:

• Spring: 6.94 kWh/day
• Summer: 5.27 kWh/day
• Autumn: 5.19 kWh/day
• Winter: 5.07 kWh/day

Spring stands out as the most productive season, likely due to clearer skies and optimal sun angles. The other seasons maintain fairly consistent output, with only slight variations between them.

Optimal Panel Positioning

For fixed panel installations in Bagong Silang, Calabarzon, the ideal tilt angle to maximize year-round solar production is 13 degrees facing South. This angle has been calculated taking into account the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data.

Environmental Considerations

While Bagong Silang's tropical climate is generally favorable for solar energy production, there are some environmental factors to consider. The region experiences a monsoon season, which could potentially impact solar output due to increased cloud cover and rainfall. To mitigate this, installing high-quality, weather-resistant panels and ensuring proper drainage systems are in place can help maintain efficiency during wet periods.

Additionally, the area may be prone to typhoons, which could pose a risk to solar installations. Implementing sturdy mounting systems and using impact-resistant panels can help protect the solar array during extreme weather events. Regular maintenance and cleaning of panels, especially after storms, can also help ensure optimal performance year-round.

Overall, with proper planning and preventative measures, Bagong Silang presents a highly suitable location for consistent solar energy production 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.

Ideally tilt fixed solar panels 13° South in Bagong Silang, Philippines

To maximize your solar PV system's energy output in Bagong Silang, Philippines (Lat/Long 14.3966, 120.9459) throughout the year, you should tilt your panels at an angle of 13° 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.

At Latitude: 14.3966, Longitude: 120.9459, the ideal angle to tilt panels is 13° South

Seasonally adjusted solar panel tilt angles for Bagong Silang, 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 Bagong Silang, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 13° South tilt angle throughout the year.

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 Bagong Silang, 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 Bagong Silang, 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 Bagong Silang, Philippines

The topography around Bagong Silang, Philippines, is characterized by a mix of gently rolling terrain and relatively flat areas. This region is part of the larger Cavite province, which is known for its diverse landscape that transitions from coastal lowlands to more elevated inland areas.

Bagong Silang itself is situated in a predominantly flat to slightly undulating area. As you move away from the town, the terrain gradually becomes more varied. To the east and northeast, the land begins to rise, forming low hills and ridges. These elevations are generally modest, rarely exceeding a few hundred meters above sea level.

To the west and southwest of Bagong Silang, the terrain tends to be flatter, eventually giving way to coastal plains as you approach Manila Bay. This area is characterized by a mix of agricultural land, urban developments, and scattered patches of vegetation.

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

1. The flatter areas to the west and southwest of Bagong Silang. These regions offer expansive, open spaces with minimal shading from natural features, which is crucial for maximizing solar energy capture.
2. Gently sloping hillsides to the east and northeast, particularly those facing south or west. These areas can provide good exposure to sunlight throughout the day while potentially requiring less land preparation than steeper terrain.
3. Former agricultural lands or brownfield sites in the surrounding municipalities. These areas often provide large, unobstructed spaces that are well-suited for solar farm development.

It's important to note that while topography is a crucial factor, other considerations such as proximity to power infrastructure, local regulations, and environmental impact assessments would also play significant roles in determining the most suitable locations for large-scale solar PV projects in this region.
