Rodriguez, Calabarzon, Philippines, located in the tropics, offers a promising environment for solar energy generation throughout the year. This location benefits from consistent sunlight and experiences seasons primarily characterized by wet and dry periods rather than significant temperature variations.

Seasonal Solar Performance

The solar energy output at this location varies across the meteorological seasons:

• Spring: 6.17 kWh/day
• Summer: 5.18 kWh/day
• Autumn: 4.40 kWh/day
• Winter: 3.98 kWh/day

Spring stands out as the most productive season, with winter showing the lowest output. However, even during winter, the energy generation remains substantial, highlighting the location's year-round suitability for solar power.

Optimal Panel Angle

For fixed panel installations in Rodriguez, Calabarzon, the ideal tilt angle to maximize year-round solar production is 12 degrees facing South. This angle has been calculated considering daily solar elevation angles, optimal panel tilt, and weighted by daily photovoltaic potential using NASA's solar irradiance data.

Environmental Considerations

While Rodriguez generally offers favorable conditions for solar energy production, there are some environmental factors to consider: Rainfall: The Philippines experiences a monsoon climate, with a wet season typically occurring from June to November. Heavy rainfall during this period can temporarily reduce solar panel efficiency. To mitigate this, ensure proper drainage systems are installed and panels are angled correctly to allow water runoff. Typhoons: The country is prone to tropical cyclones, which can pose a risk to solar installations. Robust mounting systems and high-quality, weather-resistant panels should be used to withstand strong winds and flying debris. Dust and pollution: Urban areas may experience higher levels of dust and air pollution, which can accumulate on panels and reduce efficiency. Regular cleaning and maintenance schedules should be implemented to address this issue. By taking these factors into account and implementing appropriate preventative measures, solar installations in Rodriguez can maximize their energy production potential and take full advantage of the location's favorable solar 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 Rodriguez

Seasonal solar PV output for Latitude: 14.6376, Longitude: 121.1165 (Rodriguez, 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:

 

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

To maximize your solar PV system's energy output in Rodriguez, Philippines (Lat/Long 14.6376, 121.1165) 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.

Seasonally adjusted solar panel tilt angles for Rodriguez, 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 Rodriguez, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 12° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
2° North in Summer	20° South in Autumn	30° South in Winter	8° South in Spring

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 Rodriguez, 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 Rodriguez, 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 Rodriguez, Philippines

The area around Rodriguez, Philippines, which is located at approximately 14.6376 degrees North latitude and 121.1165 degrees East longitude, has a varied and interesting topography. This region is situated in the eastern part of Metro Manila, near the border of Rizal Province.

The landscape around Rodriguez is characterized by a mix of lowland areas and hilly terrain. To the west, the land is generally flatter, forming part of the larger Metro Manila urban area. As you move eastward, the terrain becomes more elevated and rugged, transitioning into the foothills of the Sierra Madre mountain range.

The town itself is nestled in a valley, with hills and small mountains surrounding it on multiple sides. These elevated areas are often covered in lush vegetation, typical of the tropical climate in this part of the Philippines. Several rivers and streams flow through the area, including the Marikina River, which plays a significant role in shaping the local topography.

When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, there are a few factors to consider. Ideally, solar farms require relatively flat, open spaces with good sun exposure throughout the day. Given the topography of Rodriguez and its surroundings, the most suitable areas for solar PV would likely be found in the following locations:

1. The flatter, western portions of the region, where the terrain transitions into the Metro Manila lowlands. These areas may offer more expansive, open spaces that could accommodate large solar arrays.
2. Gently sloping hillsides or plateaus to the east of Rodriguez, provided they are not too steep or heavily forested. These elevated areas might benefit from reduced urban shadowing and potentially clearer skies.
3. Any large, cleared agricultural lands in the vicinity that are not prime farmland. These areas often provide the flat, unobstructed spaces ideal for solar installations.

It's important to note that while the topography plays a crucial role in determining suitable locations for solar PV, other factors such as land ownership, proximity to power infrastructure, and local regulations would also need to be considered for any large-scale solar project in this area.
