Solar PV Analysis of Marikina City, Philippines
In Marikina City, Metro Manila, Philippines (latitude: 14.6426, longitude: 121.1069), solar power generation is highly feasible due to its tropical climate and consistent sunlight exposure throughout the year. The average daily energy production per kW of installed solar varies by season, with 5.18 kWh in Summer, 4.40 kWh in Autumn, 3.98 kWh in Winter, and 6.17 kWh in Spring.
To optimize energy production at this location, fixed solar panel installations should be tilted at an angle of 12 degrees towards the South direction. Although occasional high winds or heavy rains might temporarily impact solar power generation efficiency, these factors are not significant enough to undermine the overall potential for harnessing substantial amounts of energy from solar PV systems.
When installing solar panels in Marikina City, Metro Manila, it is essential to ensure proper mounting and secure fastening to withstand any adverse weather conditions that may arise occasionally throughout the year. This will help maintain optimal performance and maximize energy production while minimizing any disruptions caused by environmental factors such as wind or rainstorms.
Overall, Marikina City's geographic location and climate make it a suitable site for generating substantial amounts of renewable energy through solar PV systems all year round.
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 Marikina City
Seasonal solar PV output for Latitude: 14.6426, Longitude: 121.1069 (Marikina 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 12° South in Marikina City, Philippines
To maximize your solar PV system's energy output in Marikina City, Philippines (Lat/Long 14.6426, 121.1069) 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 Marikina 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 Marikina City, 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 Marikina 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 Marikina 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 Marikina City, Philippines
The topography around Marikina City is generally flat, with small hills in some areas. The nearby areas that would be most suited to large-scale solar PV installations are the flat rooftops of buildings and open fields with minimal obstructions such as trees or other structures. Additionally, some areas near the coastline may also be suitable for solar PV due to their exposure to sunlight.
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.
