The location of Baras-Baras, Central Luzon, Philippines, situated in the tropics, presents a generally favorable environment for solar PV energy generation throughout the year. This area experiences consistent sunlight and is characterized more by wet and dry seasons rather than traditional four-season cycles.

Seasonal Solar Performance

Solar energy production in Baras-Baras shows impressive consistency across most of the year. Summer and autumn both yield an average of 5.36 kWh per day for each kilowatt of installed solar capacity. Winter sees only a slight dip to 5.22 kWh/day. However, spring stands out as the most productive season, with an impressive 6.94 kWh/day output. This data indicates that Baras-Baras is an excellent location for year-round solar energy production, with spring being the peak season. The minimal variation between summer, autumn, and winter suggests reliable energy generation throughout most of the year.

Optimal Panel Installation

For fixed panel installations in Baras-Baras, Central Luzon, the ideal tilt angle to maximize year-round solar production is 15 degrees facing South. This angle has been calculated taking into account the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data.

Environmental Considerations

While Baras-Baras offers favorable conditions 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 can lead to reduced sunlight and potential flooding. To mitigate these risks, several preventative measures can be taken: - Use sturdy mounting systems designed to withstand high winds - Install proper drainage systems to prevent water accumulation - Regularly clean panels to remove dust and debris, especially after storms - Consider using micro-inverters or power optimizers to minimize the impact of partial shading By implementing these measures, solar installations in Baras-Baras can maintain high energy production levels while being resilient to local weather 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 Baras-Baras

Seasonal solar PV output for Latitude: 15.5241, Longitude: 120.5638 (Baras-Baras, 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 15° South in Baras-Baras, Philippines

To maximize your solar PV system's energy output in Baras-Baras, Philippines (Lat/Long 15.5241, 120.5638) throughout the year, you should tilt your panels at an angle of 15° 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 Baras-Baras, 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 Baras-Baras, Philippines. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 15° 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	22° South in Autumn	31° South in Winter	9° 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 Baras-Baras, 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 Baras-Baras, 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 Baras-Baras, Philippines

The area surrounding Baras-Baras in the Philippines is characterized by a diverse and varied topography. Located in the province of Pangasinan on the island of Luzon, this region features a mix of flat lowlands, gently rolling hills, and more rugged terrain as you move further inland. The immediate vicinity of Baras-Baras consists primarily of flat to slightly undulating agricultural lands. These areas are predominantly used for rice cultivation, with expansive paddy fields stretching across the landscape. As you move away from the town, the terrain gradually becomes more varied. To the east and northeast, the land begins to rise, forming a series of low hills and ridges. These elevated areas are often covered in a patchwork of small farms, orchards, and patches of secondary forest. The slopes are generally gentle to moderate, making them accessible for various agricultural activities. Towards the west and southwest, the topography remains relatively flat, with occasional small hills dotting the landscape. This area is part of the larger Central Luzon plain, known for its fertile soil and extensive agricultural use.

Potential for Large-Scale Solar PV

When considering areas suitable for large-scale solar photovoltaic (PV) installations near Baras-Baras, several factors come into play. The most promising locations would be: The flat agricultural lands to the west and southwest of Baras-Baras offer excellent potential for solar PV development. These areas provide ample space, minimal shading, and easy access for construction and maintenance. However, the use of productive agricultural land for solar installations would need to be carefully balanced with food security concerns. The gently sloping hills to the east and northeast could also be suitable for solar PV installations. These areas receive good sun exposure and may be less agriculturally productive than the lowlands. The slight elevation can help reduce the risk of flooding, which is a consideration in this region. Areas of marginal agricultural land or abandoned farms near Baras-Baras could be repurposed for solar energy production. This approach would minimize the impact on current agricultural activities while making use of underutilized land. It's important to note that any large-scale solar PV development would require detailed site-specific assessments, including solar radiation studies, grid connection feasibility, and environmental impact evaluations. Additionally, local regulations and community engagement would be crucial factors in determining the most appropriate locations for such projects.
