Solar PV Analysis of Obando, Philippines
Obando, Central Luzon, Philippines is a good location for generating solar energy throughout the year. Given its tropical climate, it receives consistent sunlight most of the time which makes it suitable for solar power generation. The average amount of electricity that can be generated from each kilowatt (kW) of installed solar panels varies slightly by season: 5.27 kWh/day in summer, 5.19 kWh/day in autumn, 5.07 kWh/day in winter and 6.94 kWh/day in spring.
The best time to generate solar energy at this location would be during spring when daily output reaches its peak at nearly 7kWh per day for every kW of installed solar panels.
For fixed panel installations here, the optimal angle to tilt your panels is 14 degrees towards the south to maximize overall yearly production from your photovoltaic (PV) system.
As far as environmental or weather factors are concerned that could potentially impede solar production at this location - one significant factor could be the rainy season which typically occurs between June and November in Obando. During this period there may not only be less sunlight but also more cloud cover which can reduce efficiency of PV systems.
To mitigate these issues and ensure greater energy production throughout these months, you might consider installing a larger number of panels or using ones with higher efficiency ratings that can capture more light even under suboptimal conditions like overcast skies or lower light levels typical during rainy seasons.
Another potential issue could be dust accumulation on the surface of PV modules due to local air pollution; regular cleaning/maintenance should help keep performance high by ensuring maximum exposure to sunlight.
Lastly, if there's risk from extreme weather events such as typhoons common across parts of Philippines – sturdy installation methods using robust mounting hardware will help protect your investment while maintaining high level power output even under challenging conditions.
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 257 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 Obando
Seasonal solar PV output for Latitude: 14.7156, Longitude: 120.9415 (Obando, 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 Obando, Philippines
To maximize your solar PV system's energy output in Obando, Philippines (Lat/Long 14.7156, 120.9415) 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 Obando, 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 Obando, 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 Obando, 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 Obando, 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 Obando, Philippines
Obando is located in the province of Bulacan in the Philippines. It is a coastal town situated on flat, low-lying terrain near Manila Bay. The area is characterized by plains and agricultural lands, which are prone to flooding during heavy rains due to its proximity to several rivers including the Meycauayan River and Polo River.
This flat topography could potentially be suitable for large-scale solar PV installations as it allows for easier installation and maintenance of solar panels. However, factors such as local climate (including sun hours), soil stability, flood risk, land availability and use should also be considered.
Areas with less agricultural activity or unused lands would generally be more suited for installing large-scale solar PV systems to avoid disruption of food production. Also, areas that are less prone to flooding would also be ideal given that water can damage the solar panels and reduce their efficiency.
Moreover, rooftops of industrial buildings in nearby urban areas like Valenzuela City or Malabon City could also be utilized for installing smaller scale distributed solar PV systems without requiring additional land resources.
In any case, a thorough site assessment considering all these factors needs to be conducted before deciding on a specific location for large-scale solar PV installation.
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.
