Camalig, Bicol Region, Philippines, which is located in the Tropics, could be a good location for generating solar energy all year round. This area gets consistent sunlight throughout most of the year and seasons are often characterized more by wet and dry periods rather than significant temperature changes.

In terms of electricity output per kW of installed solar power, you can expect about 5.60kWh/day in summer, 4.74kWh/day in autumn, 4.08kWh/day in winter and 6.25kWh/day in spring at this location.

The best times to generate solar energy here would typically be during spring and summer when daily outputs are highest due to longer daylight hours and stronger sun intensity.

For a fixed panel installation at this location, tilting panels at an angle of 11 degrees South is ideal as it will maximize total yearly production from solar PV systems.

However, there may be some local factors that could hinder solar production at this location such as typhoons or heavy rainfall which are common occurrences in the Philippines especially during rainy season (June-November). These weather conditions can cause damage to panels or reduce their efficiency due to cloud cover or debris accumulation on the surface of the panels.

To prevent these issues from affecting your system’s performance significantly:

1) Install durable mounting structures that can withstand strong winds.
2) Regularly clean your panels especially after storms to remove any dust or debris that might have accumulated.
3) Consider installing protective covers over your panels if severe weather conditions are forecasted.
4) Have regular maintenance checks on your system to ensure it's always working efficiently.

Overall though with proper care & precautions taken into account; Camalig seems like a suitable place for harnessing Solar Energy effectively throughout the year!

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 Camalig

Seasonal solar PV output for Latitude: 13.1839, Longitude: 123.6517 (Camalig, 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 5.60kWh/day in Summer.

Average 4.74kWh/day in Autumn.

Average 4.08kWh/day in Winter.

Average 6.25kWh/day in Spring.

Ideally tilt fixed solar panels 11° South in Camalig, Philippines

To maximize your solar PV system's energy output in Camalig, Philippines (Lat/Long 13.1839, 123.6517) throughout the year, you should tilt your panels at an angle of 11° 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: 13.1839, Longitude: 123.6517, the ideal angle to tilt panels is 11° South

Seasonally adjusted solar panel tilt angles for Camalig, 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 Camalig, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 11° 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 Camalig, 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 Camalig, 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 Camalig, Philippines

Camalig, Philippines is located in the Bicol region of Luzon Island and is characterized by a mix of flatlands, hills, and mountains. The area includes Mount Mayon to the northeast, which is an active stratovolcano known for its perfect cone shape. The rest of the region consists mostly of agricultural land with some forests.

In terms of solar PV potential, flatlands would typically be more suitable than hilly or mountainous areas because they can accommodate large-scale installations more easily. In Camalig's case, areas such as those found towards south and southeast could potentially be good candidates due to their relatively flatter topography compared to the volcanic regions.

However, suitability for solar PV also depends on other factors like sunlight intensity (irradiance), local climate conditions (temperature and humidity), land use restrictions (e.g., protected natural areas or agricultural lands) as well as infrastructural considerations like proximity to power grids or roads. Therefore a comprehensive feasibility study would need to be conducted before determining specific locations for large-scale solar PV installations in this area.

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.
