Solar PV Analysis of Ormoc City, Philippines
Ormoc City, Eastern Visayas, Philippines is a good location for solar energy production throughout the year due to its tropical climate with consistent sunlight. The electricity output from solar panels changes slightly with seasons but remains relatively high all year round.
In summer, each kilowatt of installed solar can produce about 5.81 kilowatt-hours of electricity per day. In autumn, this decreases slightly to 4.96 kilowatt-hours per day and further reduces to 4.23 in winter before increasing again in spring to around 6.21 kilowatt-hours per day.
The most ideal times for generating solar power at this location would be during the spring and summer months when the sun's rays are strongest and days are longer.
For maximum efficiency, it is recommended that fixed panel installations at this location should be tilted at an angle of 9 degrees towards the south.
As far as environmental or weather factors go, there could be some challenges that might affect solar production in Ormoc City such as heavy rainfall or typhoons which are common in tropical areas like this one; these can lead to cloud cover reducing sunlight exposure or even damage panels if they're not properly secured.
To combat these issues, it's important that any installation includes measures against potential damage from extreme weather events - such as securing panels firmly so they won't get damaged by strong winds or using materials that can withstand heavy rain without getting damaged easily.
Also ensuring regular maintenance checks on your system will help keep it running efficiently despite any adverse weather conditions – things like cleaning off debris after a storm can make a big difference!
So overall while there may be some challenges related to weather conditions here, with proper planning and precautions you should still be able to generate substantial amounts of energy from your solar PV system 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 Ormoc City
Seasonal solar PV output for Latitude: 11.0027, Longitude: 124.6083 (Ormoc 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 9° South in Ormoc City, Philippines
To maximize your solar PV system's energy output in Ormoc City, Philippines (Lat/Long 11.0027, 124.6083) throughout the year, you should tilt your panels at an angle of 9° 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 Ormoc 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 Ormoc City, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 9° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 5° North in Summer | 17° South in Autumn | 26° South in Winter | 4° 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 Ormoc 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 Ormoc 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 Ormoc City, Philippines
Ormoc City, located in the province of Leyte in the Philippines, is characterized by a diverse topography. The city is nestled between mountain ranges to the east and west, with flat plains and rolling hills in between. The city itself sits on a delta formed by several rivers flowing from these mountains into Ormoc Bay.
Given this topography, areas most suited for large-scale solar photovoltaic (PV) installations would likely be the flat plains and gently rolling hills surrounding Ormoc City. These areas provide ample space for solar panels and are less likely to be shaded by mountains or tall trees.
However, it's important to consider other factors as well when choosing a site for solar PV installations. For instance, access to transmission infrastructure is critical since electricity produced needs to be transported efficiently. Proximity to roads may also be important for maintenance purposes.
Areas that are not used intensively for agriculture might also be good candidates since they wouldn't require displacing food production or other valuable land uses. Therefore detailed local study would need to be carried out before deciding on specific sites.
Moreover, while this region does receive significant sunlight throughout the year due its tropical climate making it suitable for solar power generation; one must also consider that Philippines being an archipelago country often experiences typhoons which could potentially damage such installations if not properly designed and secured.
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.
