Based on the data provided, Cainta, Calabarzon, Philippines is a good location for generating solar energy throughout the year. This is because it's located in the tropics where sunlight is consistent most of the year.

The amount of energy you can generate from solar panels depends on how much sunlight they get. In Cainta, Calabarzon, you can expect to generate around 5.18 kilowatt-hours (kWh) per day for each kilowatt (kW) of solar panels installed in summer, 4.40 kWh/day in autumn, 3.98 kWh/day in winter and as much as 6.17 kWh/day in spring.

So what does this mean? Well, a higher number means more energy production - so spring would be an especially good time to generate solar power at this location because it has the highest daily energy production rate.

However, while these numbers are important they're not everything - how you set up your solar panels also matters a lot! For example at this location if you want to get maximum total yearly production from your solar panels then ideally they should be tilted at an angle that faces 12 degrees South.

Now let's talk about local factors that might affect your ability to produce solar power here: One potential issue could be weather conditions like heavy rainfall or typhoons which are common in Philippines and could damage or dirty your panels reducing their efficiency; however precautions such as sturdy mounting systems and regular cleaning can help mitigate these issues.

Also topographical features like tall buildings or mountains could potentially block sunlight if they're between your panels and the sun; careful positioning of your installation can help avoid such problems though!

In conclusion: Cainta seems like a pretty good place for generating lots of clean renewable energy from sunlight all year round with some considerations taken into account during installation!

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 Cainta

Seasonal solar PV output for Latitude: 14.5777, Longitude: 121.119 (Cainta, 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 5.18kWh/day in Summer.

Average 4.40kWh/day in Autumn.

Average 3.98kWh/day in Winter.

Average 6.17kWh/day in Spring.

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

To maximize your solar PV system's energy output in Cainta, Philippines (Lat/Long 14.5777, 121.119) 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: 14.5777, Longitude: 121.119, the ideal angle to tilt panels is 12° South

Seasonally adjusted solar panel tilt angles for Cainta, 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 Cainta, 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 Cainta, 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 Cainta, 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 Cainta, Philippines

Cainta is located in the province of Rizal, in the Luzon region of the Philippines. It is part of Metro Manila's conurbation and is situated on a flat plain that gradually slopes towards Laguna de Bay, which lies to its south. The land around Cainta is primarily urban and suburban, with some agricultural areas further out.

The topography around Cainta does not present any significant barriers to large-scale solar PV installation. However, due to its predominantly urban and suburban nature, finding suitable land for such a project could be challenging.

Potential locations for large-scale solar PV installations would ideally be open spaces with minimal shading from trees or buildings. This could include unused agricultural lands or rooftops of large industrial buildings.

However, it's important to note that while physical suitability is one aspect of selecting a site for solar PV installation; factors such as local regulations, grid connectivity and social acceptance also play crucial roles in determining the feasibility of such projects.

For more specific assessments regarding potential sites for solar power plants near Cainta or anywhere else in the Philippines (or globally), specialized geographical information system (GIS) software can be used. These tools can analyze various factors including sun exposure levels throughout the year (solar irradiation), slope inclination, land use type etc., which are crucial when planning renewable energy projects like Solar PV farms.

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.
