Solar PV Analysis of Naic, Philippines
Naic, Calabarzon, Philippines (latitude: 14.3175, longitude: 120.7673) is a prime location for solar power generation due to its consistent sunlight exposure throughout the year. The average kilowatt-hour (kWh) per day per kilowatt (kW) of installed solar varies slightly by season but remains relatively high overall. In summer, one can expect an average of 5.27 kWh/day per kW; in autumn, the figure drops slightly to 5.19 kWh/day per kW; winter sees a further decrease to 5.07 kWh/day per kW; while spring boasts the highest yield with an impressive average of 6.94 kWh/day per kW.
The ideal tilt angle for fixed panel installations at this location is towards the south at a gradient of thirteen degrees for optimal efficiency and maximal energy output from your panels.
Located within the tropics, Naic experiences minimal seasonal variation in terms of temperature or daylight hours which is conducive for solar power generation year-round.
However, it's important to note that tropical climates are often characterized by distinct wet and dry periods which could potentially impact solar production due to cloud cover during rainy seasons or dust accumulation on panels during dry spells.
Preventative measures such as installing weather-resistant panels and regular cleaning can help mitigate these potential disruptions and ensure greater energy production from your installed solar system despite these environmental factors.
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 Naic
Seasonal solar PV output for Latitude: 14.3175, Longitude: 120.7673 (Naic, 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 13° South in Naic, Philippines
To maximize your solar PV system's energy output in Naic, Philippines (Lat/Long 14.3175, 120.7673) throughout the year, you should tilt your panels at an angle of 13° 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 Naic, 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 Naic, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 13° 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 Naic, 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 Naic, 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 Naic, Philippines
The topography around Naic, Philippines is mostly flat, with some rolling hills and low mountains in the surrounding area. Areas to the east of Naic have a higher elevation than those to the west, so large-scale solar PV systems would be better suited for areas on the eastern side of town. These areas should have plenty of open space and access to direct sunlight for optimal efficiency.
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.
