Solar PV Analysis of Dagupan, Philippines
Dagupan, Ilocos, Philippines is a great place for solar energy production all year round due to its consistent sunlight throughout most of the year. The amount of electricity generated from each kilowatt (kW) of installed solar panels can vary slightly by season. In summer and autumn, you can expect around 5.46 and 5.47 kilowatt-hours (kWh) per day respectively, which is pretty solid output.
In winter, the output drops a little to around 5.17 kWh/day but it's still quite good considering that winter months in many places don't usually produce as much solar power due to shorter daylight hours or weather conditions like snow covering the panels.
Springtime sees an impressive surge in energy output with about 6.95 kWh/day per kW of installed solar panel - this could be due to longer daylight hours and clearer skies commonly associated with spring weather.
To get the most out of your solar installation at this location, it's recommended that you tilt your panels at an angle facing 15 degrees South as this maximizes total yearly production from your photovoltaic system.
However, there are some factors that might affect how much energy you can generate from your solar setup in Dagupan:
1) Weather Conditions: While Dagupan does have consistent sunlight for most parts of the year, it also experiences wet seasons which might reduce overall sunlight exposure on some days because of cloud cover or heavy rainfall.
2) Environmental Factors: Dust accumulation on the surface of your panels may reduce their efficiency over time if not cleaned regularly; also nearby trees or buildings casting shadows on your installation could lower its productivity too.
To mitigate these issues:
1) Regularly clean and maintain your panels especially during dry periods when dust accumulation is likely.
2) Ensure proper placement away from potential shadow-casting objects like tall buildings or trees.
3) Consider investing in high-quality equipment designed to withstand harsh weather conditions.
By taking these steps, you can ensure that your solar installation in Dagupan is optimized for maximum 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.

Solar output per kW of installed solar PV by season in Dagupan
Seasonal solar PV output for Latitude: 16.0455, Longitude: 120.3403 (Dagupan, 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 Dagupan, Philippines
To maximize your solar PV system's energy output in Dagupan, Philippines (Lat/Long 16.0455, 120.3403) 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 Dagupan, 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 Dagupan, 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 | 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 Dagupan, 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 Dagupan, 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 Dagupan, Philippines
Dagupan, Philippines is located in the province of Pangasinan. It is a coastal city lying on the flat plains along the Lingayen Gulf with an elevation of approximately 4 meters above sea level. The region features mostly flat lands and some undulating areas, with a few hills and mountains further inland.
The topography around Dagupan is generally characterized by fertile agricultural land, rivers, fish ponds and mangrove swamps towards the coast. It has a tropical climate with plenty of sunlight throughout most parts of the year which makes it suitable for solar PV installations.
For large-scale solar PV projects, areas that are relatively flat and open would be most suitable to allow for easy installation and maximum exposure to sunlight. In Dagupan's case, unutilized or under-utilized agricultural lands away from residential areas could potentially be used for this purpose.
However, it's important to note that any plans for large-scale solar installations should take into account potential impacts on local agriculture, ecosystems as well as social implications. Furthermore, due consideration must also be given to infrastructure needs such as access roads and proximity to power grids for efficient energy transmission.
It's advisable that detailed site assessments including feasibility studies are conducted before deciding on specific locations for large scale solar PV projects in order to ensure sustainability and minimize negative impact on local communities or environment.
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;
