The location at Compostela, Central Visayas, Philippines is quite suitable for generating solar energy all year round. This is because it's located in the tropics where sunlight remains consistent throughout most of the year. However, there are variations depending on the season. In summer, you can expect to generate about 5.82 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar power. In autumn, this drops slightly to 5.16 kWh/day per kW and further decreases to 4.41 kWh/day per kW in winter before rising again to 6.20 kWh/day per kW in spring.

Therefore, if you're looking for the best time of year to generate solar power at this location, spring would be your best bet followed by summer then autumn and lastly winter.

If you're installing a fixed panel system at this location, tilting your panels towards south at an angle of 9 degrees will maximize your total yearly production from solar PV.

However, it's important to note that while Compostela is generally ideal for solar power generation due its consistent sunlight exposure throughout most of the year; there may be some local factors that could hinder optimal production such as periods of heavy rainfall during wet seasons which could limit sun exposure or cause dirt accumulation on panels reducing their efficiency.

To counter these potential issues and ensure greater energy production from your installation:

1) Consider installing a monitoring system that alerts you when output dips below expected levels so cleaning or maintenance can be scheduled promptly.
2) Install appropriate covers or shields over panels as protection against heavy rains.
3) Regular cleaning schedules should also be maintained especially after periods with high rainfall.
4) If possible install systems that allow slight adjustments in panel angles during different times of the year based on sun’s position – although not absolutely necessary since even with fixed tilt installations like suggested here; one can still achieve good overall annual output given the location’s generally favorable conditions.

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 Compostela

Seasonal solar PV output for Latitude: 10.4544, Longitude: 124.0147 (Compostela, 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:

Average 5.82kWh/day in Summer.

Average 5.16kWh/day in Autumn.

Average 4.41kWh/day in Winter.

Average 6.20kWh/day in Spring.

Ideally tilt fixed solar panels 9° South in Compostela, Philippines

To maximize your solar PV system's energy output in Compostela, Philippines (Lat/Long 10.4544, 124.0147) 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.

At Latitude: 10.4544, Longitude: 124.0147, the ideal angle to tilt panels is 9° South

Seasonally adjusted solar panel tilt angles for Compostela, 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 Compostela, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 9° South tilt angle throughout the year.

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 Compostela, 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 Compostela, Philippines.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Compostela, Philippines

Compostela is located in the province of Cebu, Philippines. The topography around Compostela mainly consists of coastal plains and rolling hills with some mountainous areas. The region has a tropical climate with high levels of sunlight throughout the year.

Regarding solar PV installations, flat or gently sloping areas would be most suitable as they allow for easier installation and maintenance, while maximizing exposure to sunlight. Coastal plains around Compostela could potentially serve as good sites for large-scale solar PV projects.

However, it's important to note that suitability for solar PV also depends on factors other than topography such as local climate conditions (amount of sunlight), land use restrictions, environmental considerations and proximity to electricity grids for power transmission.

A detailed site-specific assessment would be required to identify the best locations for large-scale solar PV in and around Compostela. This would involve analysis not only of topographical data but also factors like local weather patterns, land ownership status and existing infrastructure among others.

Additionally, rooftops in urban or residential areas can also be utilized for installing smaller scale distributed solar systems. These can collectively contribute a significant amount of power while avoiding potential issues related to land acquisition that may arise with larger scale projects.

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.
