Solar PV Analysis of Baguio City, Philippines
The geographical coordinates of Baguio City, Cordillera, Philippines (16.4124 latitude, 120.5933 longitude) make it an excellent location for solar power generation due to its tropical climate and consistent sunlight exposure throughout the year. The city's solar energy production averages 5.46kWh per day for each kW of installed panels in the summer season, while autumn sees a slight increase to 5.47kWh/day per kW installed. Winter experiences a small drop with an average output of 5.17kWh/day per kW installed, whereas spring boasts the highest yield at approximately 6.95kWh/day per kW installed.
For optimal performance and efficiency in this location, it is recommended to tilt fixed solar panels at an angle of 15 degrees facing southward; this helps maximize sun exposure and consequently energy production.
While Baguio City is generally well-suited for solar power generation due to its favorable weather conditions and abundant sunlight, potential challenges may arise from occasional heavy rainfall or strong winds that could impact panel performance or cause damage if not properly secured during installation.
However, these weather conditions are not common occurrences in this region; hence they do not significantly impede overall solar power generation capabilities here on a regular basis.
To mitigate against such potential issues when installing solar panels in Baguio City or similar locations with occasional extreme weather events, ensure secure mounting systems are used that can withstand high wind speeds and consider protective measures such as waterproofing solutions to prevent water damage from heavy rains.
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 Baguio City
Seasonal solar PV output for Latitude: 16.4124, Longitude: 120.5933 (Baguio City, 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 15° South in Baguio City, Philippines
To maximize your solar PV system's energy output in Baguio City, Philippines (Lat/Long 16.4124, 120.5933) throughout the year, you should tilt your panels at an angle of 15° 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 Baguio City, 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 Baguio City, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 15° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 0° in Summer | 22° South in Autumn | 32° South in Winter | 10° 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 Baguio City, 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 Baguio City, 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 Baguio City, Philippines
The topography around Baguio City, Philippines is mountainous and hilly. Areas with plenty of sunlight and a flat terrain would be most suited for large-scale solar PV systems. The nearby towns of La Trinidad, Itogon, Sablan, Tuba, Tublay, Kapangan and Bakun all have relatively flat terrain that could potentially be used for this purpose.
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?
Yes, there are several incentives for businesses wanting to install solar energy in the Philippines. These include:
1. The Feed-in Tariff (FiT) program, which provides a guaranteed rate of return on investments in renewable energy projects;
2. Tax credits and exemptions from certain taxes;
3. Net metering programs that allow businesses to sell excess electricity back to the grid;
4. Grants and loans from government agencies such as the Department of Energy and the Philippine Solar Power Alliance;
5. Technical assistance from organizations like USAID’s Clean Energy Program; and
6. Access to financing through banks, venture capital firms, or other sources of private capital.
