Solar PV Analysis of Toledo City, Philippines
The city of Toledo in the Philippines is a good place for generating solar energy all year round due to its tropical climate, which provides consistent sunlight most of the year. The seasons are typically characterized by wet and dry periods rather than significant temperature fluctuations.
In terms of electricity output from solar panels, you can expect to generate on average 5.62 kilowatt-hours (kWh) per day in summer for each kilowatt (kW) of installed solar power. This decreases slightly in autumn and winter, with averages of 5.03 kWh/day and 4.41 kWh/day respectively, but then increases again in spring to an average of 6.10 kWh/day.
Therefore, while you can generate solar energy throughout the year at this location, spring would be the best time since that's when you'd get maximum output from your panels.
If you're planning on installing fixed panel solar systems here, it's ideal to tilt them at an angle facing 9 degrees South as this will maximize total production from your system all year round.
As for possible factors that could hinder solar production at this location - one major concern could be weather conditions during the wet season which might involve heavy rainfall or cloud cover reducing sunlight exposure on panels. Also dust or debris accumulation on panels could potentially reduce their efficiency if not cleaned regularly.
To mitigate these issues:
1) For heavy rainfall or cloudy weather - unfortunately there isn't much one can do about nature! However having a battery storage solution connected with your system will allow storing excess power generated during sunny days which can then be used during less sunny ones.
2) For dust/debris accumulation - regular cleaning/maintenance should be scheduled especially just after the end of dry season when dust levels may be higher due to lack thereof rainfalls washing away accumulated dirt/debris off panels surfaces.
Overall though given high sun exposure levels throughout most parts of year along with right installation practices, Toledo City, Central Visayas, Philippines is a location well suited for solar energy production.
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 Toledo City
Seasonal solar PV output for Latitude: 10.3808, Longitude: 123.6381 (Toledo 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 Toledo City, Philippines
To maximize your solar PV system's energy output in Toledo City, Philippines (Lat/Long 10.3808, 123.6381) 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 Toledo 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 Toledo 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 |
|---|---|---|---|
| 6° 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 Toledo 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 Toledo 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 Toledo City, Philippines
Toledo City is located on the western coast of Cebu, Philippines. The topography of Toledo City is generally hilly and mountainous, with flat areas along the coastal regions. The city is surrounded by higher elevations to the east while it descends towards the Tanon Strait in the west.
As for solar PV installations, flat areas are generally more suited because they require less land preparation and make installation easier. Therefore, coastal plains around Toledo City may be more suitable for large-scale solar PV projects.
However, it's important to note that suitability for solar power doesn't only depend on topography but also on factors such as local climate conditions and proximity to power grids or demand centers etc.
Despite being hilly and mountainous in some parts; if properly planned and designed considering all factors including environmental impact, parts of Toledo City could still host successful large-scale solar PV projects.
Finally remember that these assessments often require detailed site-specific studies involving both field surveys and technical feasibility analyses performed by experts in renewable energy development.
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.
