The location at Angono, Calabarzon, Philippines is generally good for generating energy using solar photovoltaic (PV) panels throughout the year. This is because it's located in the tropics where sunlight is pretty consistent most of the time. The amount of electricity that can be produced per unit (kW) of installed solar varies slightly with each season: you can expect around 5.18 kWh/day in Summer, 4.40 kWh/day in Autumn, 3.98 kWh/day in Winter, and a high of 6.17 kWh/day in Spring.
Spring seems to be the best time to generate solar power here because it produces more electricity than other seasons, followed by summer then autumn and winter respectively.
For a fixed panel installation at this location, tilting your panels at an angle of about 12 degrees towards South will help you get maximum production from your solar PV system all year round.
However, there are some factors that could potentially affect or reduce your solar production here:
1) Weather: Although sunlight is generally consistent throughout most part of the year due to its tropical climate; heavy rainfall during wet seasons may reduce sun exposure which could lower energy output from your panels during these periods.
2) Environmental Factors: If there are tall buildings or trees near your installation site they might cast shadows on your panels thereby reducing their efficiency.
To help ensure greater energy production despite these challenges:
a) Install a weather monitoring system alongside with your PV system so as to predict weather patterns and adjust operations accordingly.
b) Choose an installation site with minimal shading throughout the day if possible.
c) Regular maintenance such as cleaning off dust or debris from panel surfaces can also enhance overall performance over time.
d) Installing adjustable tilt mounts could allow for changing angles depending on seasonal variations for optimal performance all year round.
In conclusion; while there are minor challenges like weather changes and potential shading issues; Angono Philippines still remains a great spot for solar PV installation due to its consistent sunlight exposure.
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 Angono
Seasonal solar PV output for Latitude: 14.5258, Longitude: 121.1546 (Angono, 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 12° South in Angono, Philippines
To maximize your solar PV system's energy output in Angono, Philippines (Lat/Long 14.5258, 121.1546) throughout the year, you should tilt your panels at an angle of 12° 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 Angono, 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 Angono, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 12° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 2° North in Summer | 20° 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 Angono, 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 Angono, 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 Angono, Philippines
Angono, Philippines is located in the province of Rizal and is part of the larger Metro Manila area. The topography around Angono consists mainly of flat lowlands with some hilly areas towards the east. It is situated near Laguna de Bay, which is the largest lake in the Philippines.
The town itself has a mix of residential, commercial and industrial areas. There are also agricultural lands surrounding it, mainly used for rice cultivation and fish farming.
In terms of solar PV potential, open flat spaces such as agricultural lands would be ideal for large-scale installations due to their exposure to sunlight. However, considerations must be made regarding land use conflicts and potential impact on local agriculture or other activities.
Another option could be installing solar panels on rooftops within urbanized areas or industrial zones. This can make use of existing structures without needing additional land space.
Lastly, floating solar farms could potentially be implemented on Laguna de Bay given its proximity to Angono. This has been done in other places around the world where land space might be limited but there are large bodies of water available.
However, any decision regarding large-scale solar PV installations should take into account various factors including local climate conditions (amount of sunlight received), environmental impacts, social acceptance and economic feasibility among others.
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.
