Floridablanca, Central Luzon, Philippines, located in the tropics, offers a promising environment for solar energy generation throughout the year. This location benefits from consistent sunlight and experiences wet and dry seasons rather than traditional four-season weather patterns.
Solar Energy Production Across Seasons
The solar energy output at Floridablanca remains relatively stable throughout the year, with a notable increase during spring. Here's a breakdown of the expected daily electricity output per kilowatt of installed solar capacity: • Spring: 6.94 kWh/day • Summer: 5.27 kWh/day • Autumn: 5.19 kWh/day • Winter: 5.07 kWh/day Spring clearly stands out as the most productive season, likely due to clearer skies and optimal sun angles. The other seasons show consistent performance, with only slight variations between them.Optimal Panel Installation
For fixed panel installations in Floridablanca, Central Luzon, the ideal tilt angle to maximize year-round solar production is 14 degrees facing South. This angle has been calculated taking into account the location's latitude, daily solar elevation angles, and potential daily PV output throughout the year.Environmental and Weather Considerations
While Floridablanca's tropical 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. Heavy rainfall: During the wet season, frequent rain can reduce solar output. Installing panels at the optimal angle helps with water runoff and ensures quicker drying after rain events. 3. High humidity: The tropical climate's high humidity can lead to moisture buildup on panels. Regular cleaning and maintenance, along with proper sealing of electrical components, can help prevent issues related to humidity. 4. Potential for dust and debris: During dry seasons, dust accumulation on panels can reduce efficiency. Implementing a regular cleaning schedule and considering automated cleaning systems can help maintain optimal performance. By addressing these factors during installation and maintenance, solar energy systems in Floridablanca can operate efficiently and take full advantage of the location's favorable solar conditions 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 Floridablanca
Seasonal solar PV output for Latitude: 14.9756, Longitude: 120.5313 (Floridablanca, 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 Floridablanca, Philippines
To maximize your solar PV system's energy output in Floridablanca, Philippines (Lat/Long 14.9756, 120.5313) 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 Floridablanca, 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 Floridablanca, 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 | 30° South in Winter | 8° 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 Floridablanca, 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 Floridablanca, Philippines.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Floridablanca, Philippines
The area around Floridablanca, Philippines, is characterized by a diverse topography that includes both flat lowlands and hilly terrain. Floridablanca itself is situated in a relatively flat area, which is part of the larger Central Luzon plain. This plain is one of the most extensive lowland regions in the Philippines, known for its fertile soil and agricultural productivity.
To the west of Floridablanca, the terrain gradually rises into the Zambales Mountains. These mountains form a natural barrier between the central plains and the western coast of Luzon. The foothills of the Zambales range begin to appear within a few kilometers of Floridablanca, creating a picturesque backdrop to the town.
To the east and southeast, the landscape remains predominantly flat, extending towards the Pampanga River and its tributaries. This area is part of an expansive river delta system, which includes numerous streams and irrigation channels that support the region's agriculture.
For large-scale solar PV installations, the most suitable areas would likely be found in the flat, open spaces to the east and southeast of Floridablanca. These areas offer several advantages for solar energy development:
- The flat terrain makes construction and maintenance easier and more cost-effective.
- There are fewer natural obstacles that could cast shadows on solar panels, maximizing sun exposure throughout the day.
- The proximity to existing infrastructure and power grids in the Central Luzon region could facilitate easier integration of solar-generated electricity.
- The agricultural lands in this area, if not highly productive, could potentially be repurposed for solar farms, creating a dual-use scenario for the land.
However, it's important to note that any large-scale solar project would need to carefully consider environmental impacts, land use regulations, and the balance between energy production and agricultural needs in this fertile region. Additionally, while the flat areas are generally more suitable, some gently sloping hillsides to the west could also be considered if they offer good sun exposure and don't interfere with important ecosystems or agricultural activities.
Philippines solar PV Stats as a country
Philippines ranks 40th in the world for cumulative solar PV capacity, with 1,370 total MW's of solar PV installed. Each year Philippines is generating 13 Watts from solar PV per capita (Philippines ranks 71st in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Philippines?
