Potrero, Metro Manila, Philippines is a great place for generating energy via solar photovoltaic (PV) systems all year round. This is because it's located in the Tropics where sunlight is quite consistent throughout most of the year. The amount of electricity that can be generated from each kilowatt of installed solar varies slightly by season but remains fairly high: 5.27kWh/day in Summer, 5.19kWh/day in Autumn, 5.07kWh/day in Winter and peaks at 6.94kWh/day in Spring.

In terms of ideal times to generate solar power at this location, Spring seems to be the best due to its higher daily output compared to other seasons.

For a fixed panel installation at this location, tilting panels at an angle of 14 degrees towards South will help maximize total year-round production from solar PV.

However, there are some factors that could potentially impede solar production here such as heavy rainfall during wet seasons or dust and debris covering the panels which can reduce their efficiency. To ensure greater energy production despite these challenges:

1) Regular maintenance including cleaning the panels especially after heavy rains or windy days when dust might accumulate on them would be recommended.
2) Installing protective measures like weather-resistant casing for PV systems can help protect against damage during extreme weather conditions.
3) Having a good drainage system around your installation site can also prevent water accumulation which could lead to system damages.

Overall though, Potrero offers very favourable conditions for harnessing solar energy throughout the year with only minor adjustments needed to overcome potential environmental or weather-related impediments.

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 Potrero

Seasonal solar PV output for Latitude: 14.6708, Longitude: 120.9811 (Potrero, 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 5.27kWh/day in Summer.

Average 5.19kWh/day in Autumn.

Average 5.07kWh/day in Winter.

Average 6.94kWh/day in Spring.

Ideally tilt fixed solar panels 14° South in Potrero, Philippines

To maximize your solar PV system's energy output in Potrero, Philippines (Lat/Long 14.6708, 120.9811) throughout the year, you should tilt your panels at an angle of 14° 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: 14.6708, Longitude: 120.9811, the ideal angle to tilt panels is 14° South

Seasonally adjusted solar panel tilt angles for Potrero, 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 Potrero, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 14° 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 Potrero, 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 Potrero, 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 Potrero, Philippines

Potrero, located in Malabon City, Philippines, is part of the Metro Manila area. The topography is generally flat and urbanized with a low elevation level as it's situated near the coast. The region experiences a tropical climate with high temperatures and humidity throughout the year.

Regarding solar PV installations, large-scale projects would require vast open spaces with minimal shading for maximum efficiency. Given Potrero's highly urbanized nature, finding such spaces within the city might be challenging. However, nearby provinces like Bulacan or Pampanga have more rural areas that could potentially accommodate large-scale solar farms.

Additionally, rooftops of commercial and residential buildings in Potrero itself can also be utilized for smaller-scale solar panel installations. These can collectively contribute to significant clean energy generation without requiring additional land resources.

As always though before proceeding with any installation project it’s important to conduct a detailed site analysis including factors like sun path (solar irradiance), local weather patterns and potential physical obstructions to ensure optimal performance from the PV systems.

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.
