Calapan, Mimaropa, Philippines is a good location for generating solar energy all year round due to its tropical climate, which provides consistent sunlight throughout most of the year. The amount of electricity that can be produced from each kilowatt (kW) of installed solar panels varies by season. In summer, you can expect about 5.57 kilowatt-hours (kWh) per day; in autumn, it's around 4.96 kWh/day; in winter, it drops slightly to 4.39 kWh/day; and in spring, it increases significantly to 6.62 kWh/day.

The best time of the year for generating solar power at this location is during the spring when sunlight is maximized and therefore energy production is at its highest.

For fixed panel installations at this location, tilting the panels at an angle of 12 degrees towards the South will help maximize total yearly production from your solar photovoltaic system.

However, there might be some local factors that could potentially hinder solar production in Calapan City such as typhoons or heavy rainstorms during wet seasons which may block sunlight and damage equipment. To prevent these issues from impacting your energy output too much:

1) Install durable mounting systems that can withstand strong winds.
2) Regularly clean and maintain your panels especially after severe weather conditions.
3) Consider installing a backup power source or storage system like batteries so you still have electricity even when your panels aren't producing as much due to bad weather conditions.
4) If possible choose high-quality PV modules with increased resistance against potential induced degradation (PID), which often happens under harsh climatic conditions.

In conclusion: Calapan City has great potential for harnessing solar energy but careful planning and maintenance are required to ensure maximum efficiency and longevity of your system given environmental challenges like typhoons or heavy rains typical for this area.

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 Calapan

Seasonal solar PV output for Latitude: 13.4142, Longitude: 121.1774 (Calapan, 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 5.57kWh/day in Summer.

Average 4.96kWh/day in Autumn.

Average 4.39kWh/day in Winter.

Average 6.62kWh/day in Spring.

Ideally tilt fixed solar panels 12° South in Calapan, Philippines

To maximize your solar PV system's energy output in Calapan, Philippines (Lat/Long 13.4142, 121.1774) throughout the year, you should tilt your panels at an angle of 12° 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: 13.4142, Longitude: 121.1774, the ideal angle to tilt panels is 12° South

Seasonally adjusted solar panel tilt angles for Calapan, 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 Calapan, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 12° 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 Calapan, 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 Calapan, 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 Calapan, Philippines

Calapan, Philippines is located in the northeastern part of Mindoro Island. The topography of the area is characterized by a mix of flat lowlands and hilly terrains. The city itself is mostly flat, which makes it ideal for agriculture and urban development. Towards the north and west, you will find mountainous regions with peaks that are part of the Halcon Mountain range.

In terms of solar PV installations, areas with flat terrain would be most suitable as they allow for easier installation and maintenance. As such, the flat lowlands within Calapan City could potentially be good locations for large-scale solar PV projects.

Moreover, considering that Calapan experiences a tropical climate with ample sunshine throughout the year (except during monsoon season), this further enhances its suitability for solar energy generation.

However, factors like land use patterns (agricultural lands or populated areas may not be available or suitable for setting up large scale solar plants), proximity to power grids (for easy transmission), local regulations regarding renewable energy projects etc., must also be taken into account before deciding on specific sites within or around Calapan city.

A detailed feasibility study including site surveys would provide more accurate insights about best locations suited to largescale solar PV in this region.

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.
