San Leonardo, Central Luzon, Philippines, situated at 15.3572° N, 120.9653° E, offers a promising location for solar energy production throughout the year. This tropical setting benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than temperature variations.

Solar Energy Potential

The solar energy potential in San Leonardo is relatively stable across seasons, with a notable peak during spring. The average daily electricity output per kilowatt of installed solar capacity is as follows: • Summer and Autumn: 5.36 kWh/day • Winter: 5.22 kWh/day • Spring: 6.94 kWh/day This data indicates that spring is the most productive season for solar energy generation in San Leonardo, Central Luzon, with a significant increase in output compared to other seasons. The consistency in summer and autumn production, coupled with only a slight decrease in winter, suggests that solar PV systems can provide reliable energy throughout the year.

Optimal Panel Tilt

For fixed solar panel installations in San Leonardo, Central Luzon, the ideal tilt angle to maximize year-round energy production is 14 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 San Leonardo's tropical climate 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 high-quality, wind-resistant mounting systems and panels designed to withstand extreme weather conditions. 2. Heavy rainfall: During the wet season, frequent rain and cloud cover may temporarily reduce solar output. Installing panels with good low-light performance can help maintain efficiency during overcast periods. 3. High humidity: The tropical climate's high humidity levels can potentially lead to moisture-related issues in solar equipment. Using corrosion-resistant materials and ensuring proper sealing of electrical components can prevent damage and maintain system longevity. 4. Dust and pollution: Agricultural activities in the region may contribute to dust accumulation on panels. Regular cleaning and maintenance, possibly including automated cleaning systems, can help maintain optimal performance. By addressing these factors during the design and installation phase, solar PV systems in San Leonardo can be optimized to harness the location's excellent solar potential throughout the year.

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 San Leonardo

Seasonal solar PV output for Latitude: 15.3572, Longitude: 120.9653 (San Leonardo, 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 14° South in San Leonardo, Philippines

To maximize your solar PV system's energy output in San Leonardo, Philippines (Lat/Long 15.3572, 120.9653) throughout the year, you should tilt your panels at an angle of 14° 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 San Leonardo, 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 San Leonardo, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 14° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
1° North in Summer	21° South in Autumn	31° South in Winter	9° 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 San Leonardo, 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 San Leonardo, 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 San Leonardo, Philippines

The topography around San Leonardo, Philippines, is characterized by a mix of flat lowlands and gently rolling terrain. This area is situated in the central plains of Luzon, known as the Central Luzon Basin. The landscape is predominantly composed of agricultural fields, with rice paddies being a common sight. The terrain gradually rises towards the east, where the foothills of the Sierra Madre mountain range begin to emerge. To the west of San Leonardo, the land remains relatively flat, extending towards the Pampanga River. This river system has played a significant role in shaping the local topography, creating fertile alluvial plains that are ideal for agriculture. The area also features scattered patches of woodland and small water bodies, including streams and irrigation canals that crisscross the farmlands.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, the flat agricultural lands surrounding San Leonardo present promising opportunities. These expansive, open areas receive ample sunlight throughout the year, making them ideal for solar energy production. The regions to the west and southwest of San Leonardo, where the terrain remains predominantly flat, would be particularly well-suited for solar PV projects. These areas offer large, unobstructed spaces that could accommodate extensive arrays of solar panels. The lack of significant elevation changes in these locations would simplify construction and maintenance processes for solar farms. Additionally, the agricultural lands that are less productive or have been left fallow could be repurposed for solar energy production. This approach would allow for the dual use of land, potentially combining solar power generation with certain types of crop cultivation, a concept known as agrivoltaics. It's important to note that while the flat terrain is advantageous for solar PV installation, careful consideration must be given to factors such as flood risk, especially in areas close to the Pampanga River and its tributaries. Elevated locations within the flatlands, if available, might be preferred to mitigate potential flooding issues. Lastly, areas near existing power infrastructure and transportation networks would be beneficial for large-scale solar PV projects, as they would facilitate easier grid connection and access for construction and maintenance. The proximity of San Leonardo to major roads and urban centers in Central Luzon could provide these advantages for nearby solar development sites.
