Solar PV Analysis of Tuguegarao City, Philippines
Tuguegarao City, Cagayan Valley, Philippines is a good location for year-round solar energy production. This is because it's located in the tropics, where sunlight is fairly consistent throughout the year. The seasons here are usually distinguished more by wet and dry periods rather than drastic changes in temperature.
The amount of electricity that can be generated from solar energy varies with each season. In summer and spring, you can expect to generate 6.10kWh/day and 6.70kWh/day respectively per kW of installed solar power system. These are the ideal times for generating solar power due to more sunlight hours.
During autumn and winter, the output decreases slightly to 4.91kWh/day and 3.84kWh/day respectively per kW of installed solar power system due to fewer daylight hours.
For optimum results from your solar panels at this location, they should be fixed at an angle facing 15 degrees South to capture as much sunlight as possible throughout the year.
However, there could be some local factors that might hinder optimal performance of your solar panels in Tuguegarao City:
1) Rainy Season: As mentioned earlier, Tuguegarao has a wet season which could reduce the amount of sunlight reaching your panels thereby reducing their efficiency.
2) Dust & Debris: Being a city area there may be dust or other debris which could accumulate on your panel surface blocking sunlight penetration leading to reduced efficiency.
To overcome these issues:
1) Regular Cleaning: Ensure regular cleaning of your panels especially during dry seasons when dust accumulation might be high.
2) Weather-Proofing: Consider weather-proofing measures like protective covers during heavy rainfalls or storms.
3) Professional Installation: Get professional help for installation ensuring optimal tilt angle and direction for maximum exposure to sun rays all through the year.
4) Regular Maintenance: Regular maintenance checks will ensure any damage or issue is detected early preventing long term loss in efficiency.
In conclusion, Tuguegarao City is a great place for solar energy production with its consistent sunlight. However, local factors like wet seasons and dust accumulation need to be considered and managed for optimal performance of your solar panels.
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 Tuguegarao City
Seasonal solar PV output for Latitude: 17.608, Longitude: 121.7219 (Tuguegarao 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 Tuguegarao City, Philippines
To maximize your solar PV system's energy output in Tuguegarao City, Philippines (Lat/Long 17.608, 121.7219) 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 Tuguegarao 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 Tuguegarao 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 |
|---|---|---|---|
| 1° South in Summer | 23° South in Autumn | 33° 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 Tuguegarao 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 Tuguegarao 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 Tuguegarao City, Philippines
Tuguegarao City in the Philippines is located in the Cagayan Valley region, which is characterized by a broad flat landscape surrounded by mountains. The city lies near the Sierra Madre and Cordillera mountain ranges to the east and west respectively, while to its north lies a vast plain leading up to the Babuyan Channel.
The city has a tropical climate with abundant sunlight throughout most of the year, making it an excellent location for solar power generation. The relatively flat terrain in and around Tuguegarao City would be ideal for large-scale solar PV installations.
In terms of specific areas suited for large-scale solar PV:
1. The plains surrounding Tuguegarao City: These areas offer ample space for setting up large arrays of photovoltaic panels.
2. Unused agricultural lands: If there are any unused or less productive agricultural lands around Tuguegarao City, these could potentially be converted into sites for solar farms.
3. Industrial zones: Any industrial zones or brownfield sites within or close to Tuguegarao City could also serve as potential locations for large-scale solar PV installations.
However, before any decisions are made on specific locations, detailed site assessments should be conducted considering factors like land ownership rights, proximity to power grids (for ease of connection), environmental impact assessments etc., along with consultation with local communities and stakeholders.
