Buona Vista, Singapore, situated at 1.2827° N, 103.7915° E, presents a favorable location for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than traditional temperature-based seasons.

Year-round Solar Energy Potential

The solar energy output at Buona Vista demonstrates remarkable consistency across all meteorological seasons. Spring stands out as the most productive period, with an average daily output of 5.43 kWh per kW of installed solar capacity. Summer, somewhat counterintuitively, shows the lowest output at 4.76 kWh/day, while autumn and winter maintain strong production levels at 5.10 kWh/day and 5.00 kWh/day, respectively. This pattern indicates that Buona Vista is an excellent location for year-round solar energy generation, with only minor fluctuations between seasons. The consistently high output throughout the year ensures a steady and reliable source of renewable energy.

Optimal Panel Tilt

For fixed panel installations in Buona Vista, the ideal tilt angle to maximize year-round solar production is just 1 degree South. This nearly horizontal orientation is due to the location's proximity to the equator, where the sun's path remains relatively high in the sky throughout the year.

Environmental Considerations

While Buona Vista offers excellent conditions for solar energy production, there are some environmental factors to consider: 1. High humidity: Singapore's tropical climate means high humidity levels, which can potentially lead to moisture-related issues for solar equipment. 2. Heavy rainfall: The region experiences significant rainfall, particularly during the monsoon seasons, which could temporarily reduce solar output. To mitigate these factors, the following preventative measures can be taken during solar installation: - Use high-quality, weather-resistant solar panels and components designed for tropical climates. - Ensure proper sealing and waterproofing of all electrical connections and equipment. - Implement effective drainage systems to prevent water accumulation on or around the solar panels. - Regular cleaning and maintenance to remove any dust or debris that may accumulate due to the humid environment. By implementing these measures, solar installations in Buona Vista can maximize their energy production potential and maintain long-term efficiency despite the challenging tropical 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 12 locations across Singapore. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 1° South in Buona Vista, Singapore

To maximize your solar PV system's energy output in Buona Vista, Singapore (Lat/Long 1.2827, 103.7915) throughout the year, you should tilt your panels at an angle of 1° 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 Buona Vista, Singapore

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 Buona Vista, Singapore. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 1° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
15° North in Summer	7° South in Autumn	16° South in Winter	5° North 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 Buona Vista, Singapore

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 Buona Vista, Singapore.

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 Buona Vista, Singapore

Buona Vista, located in the western part of Singapore, is characterized by a mix of urban development and green spaces. The topography of the area is generally flat to gently undulating, typical of Singapore's landscape. The region sits at a low elevation, with most of the land being only a few meters above sea level. The surrounding area features a combination of residential neighborhoods, commercial districts, and educational institutions. To the north and east of Buona Vista, you'll find more densely built-up areas with high-rise buildings and apartment complexes. To the south and west, the landscape becomes slightly more varied, with pockets of greenery interspersed among the urban development.

Notable Topographical Features

One of the most prominent topographical features near Buona Vista is the Kent Ridge Park, located just to the south. This park sits on a ridge that offers slightly higher elevation compared to the surrounding areas, providing some of the only notable changes in elevation in the vicinity. The park's hilly terrain and lush vegetation create a stark contrast to the flat, urbanized areas nearby. Another significant feature is the Ulu Pandan Park Connector, which runs along a canal to the north of Buona Vista. This linear park follows the natural contours of the land, creating a green corridor through the urban landscape.

Potential for Large-scale Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations would be flat, open spaces with minimal shading from buildings or trees. Given these criteria, a few areas near Buona Vista show potential: 1. The rooftops of large industrial or commercial buildings in the one-north business park, located just east of Buona Vista, could provide suitable spaces for solar panel installation. These buildings often have flat roofs with minimal obstructions, making them ideal for solar PV systems. 2. The open spaces around the National University of Singapore campus, situated to the south of Buona Vista, might offer potential sites for ground-mounted solar arrays. However, careful consideration would need to be given to preserving green spaces and avoiding disruption to campus activities. 3. The area around Clementi, to the west of Buona Vista, includes some larger open spaces that could potentially accommodate solar installations. However, these would need to be carefully planned to avoid conflict with existing land uses and future development plans. It's important to note that Singapore's high population density and limited land area pose challenges for large-scale solar PV installations. As a result, the most practical approach in this urban environment would likely involve a combination of rooftop installations on existing buildings and creative use of available open spaces, rather than dedicating large tracts of land solely to solar energy production.
