Norzagaray, Central Luzon, Philippines, located at 14.9082° N, 121.0414° E, offers a promising environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasonal variations primarily characterized by wet and dry periods rather than significant temperature fluctuations.

Seasonal Solar Performance

Solar panel performance in Norzagaray varies across the meteorological seasons. Spring stands out as the most productive period, with an impressive daily output of 6.17 kWh per kW of installed solar capacity. Summer follows with 5.18 kWh/day, while autumn and winter see slightly reduced but still substantial outputs of 4.40 kWh/day and 3.98 kWh/day, respectively.

Optimal Panel Positioning

For fixed solar panel installations in Norzagaray, Central Luzon, the ideal tilt angle to maximize year-round energy production is 13 degrees facing South. This angle takes into account the location's latitude, the Earth's elliptical orbit, and daily solar elevation angles to ensure optimal sunlight capture throughout the year.

Environmental Considerations

While Norzagaray's tropical climate is generally favorable for solar energy production, there are some environmental factors to consider: 1. Typhoons: The Philippines is prone to tropical cyclones, which can potentially damage solar installations. 2. Heavy rainfall: The wet season may lead to reduced sunlight and increased cloud cover. To mitigate these risks, it's crucial to implement robust mounting systems capable of withstanding high winds and heavy rain. Additionally, using high-quality, weather-resistant solar panels and ensuring proper drainage around the installation can help maintain optimal performance even during challenging weather conditions.

Maximizing Solar Potential

To make the most of Norzagaray's solar potential, consider implementing a regular cleaning schedule to remove dust and debris, especially during the dry season. Installing a monitoring system can help track performance and quickly identify any issues. Lastly, combining solar PV with energy storage solutions can help balance out production variations between seasons and ensure a more consistent energy supply 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 Norzagaray

Seasonal solar PV output for Latitude: 14.9082, Longitude: 121.0414 (Norzagaray, 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 13° South in Norzagaray, Philippines

To maximize your solar PV system's energy output in Norzagaray, Philippines (Lat/Long 14.9082, 121.0414) throughout the year, you should tilt your panels at an angle of 13° 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 Norzagaray, 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 Norzagaray, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 13° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
1° North in Summer	21° 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 Norzagaray, 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 Norzagaray, 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 Norzagaray, Philippines

The topography around Norzagaray, Philippines, is characterized by a mix of lowland plains and hilly terrain. This area is situated in the province of Bulacan, which is part of the Central Luzon region. Norzagaray itself is located on the eastern edge of the province, close to the Sierra Madre mountain range.

The immediate vicinity of Norzagaray features gently rolling hills and some flat areas, with elevations gradually increasing as you move eastward towards the Sierra Madre mountains. The Angat River, an important water source for the region, flows through this area, creating some valleys and gorges in the landscape.

To the west of Norzagaray, the terrain becomes flatter as it transitions into the Central Luzon plain. This expansive lowland area stretches towards Manila Bay and is known for its agricultural productivity.

For large-scale solar PV installations, the most suitable areas nearby would likely be found in the flatter regions to the west and southwest of Norzagaray. These areas offer several advantages for solar energy development:

1. The relatively flat terrain makes construction and maintenance easier.
2. There is less natural shading from hills or mountains.
3. The land is generally more accessible, which is beneficial for transportation of equipment and grid connection.
4. Some of these areas may already be used for agriculture, potentially allowing for dual-use solar farms that combine energy production with crop cultivation.

However, it's important to note that site-specific assessments would be necessary to determine the most suitable locations. Factors such as local climate conditions, existing land use, proximity to power infrastructure, and environmental considerations would all need to be taken into account when selecting the ideal sites for large-scale solar PV projects in this region.
