Queenstown Estate, Singapore (Lat: 1.2958, Long: 103.8025) is an excellent location for solar PV generation due to its consistent sunlight throughout the year and high average daily energy production per kW of installed solar in each season (4.77 kWh in Summer, 5.08 kWh in Autumn, 5.01 kWh in Winter, and 5.41 kWh in Spring). The highest amount of solar energy is generated during the Spring months as there are more sunny days and less rain compared to other seasons.
Situated within the Tropics, Queenstown Estate experiences relatively constant temperatures and sunlight all year round, ensuring a stable environment for solar power generation with no significant weather-related impediments. The ideal angle for fixed panel installations at this location is a tilt of 1 degree facing South to optimize exposure to sunlight.
While there may be occasional clouds or rainfall that could temporarily reduce solar production at this location, these factors are not significant enough to negatively impact overall performance significantly. To further ensure optimal energy production from installed panels while accounting for potential environmental factors such as dust or debris accumulation on panel surfaces, regular maintenance and cleaning should be performed as part of a comprehensive system management plan.
Overall, Queenstown Estate's favorable climate conditions combined with proper installation techniques make it an ideal location for generating clean and efficient solar power year-round without major hindrances from local environmental or topographical factors.
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.

Solar output per kW of installed solar PV by season in Queenstown Estate
Seasonal solar PV output for Latitude: 1.2958, Longitude: 103.8025 (Queenstown Estate, Singapore), 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 1° South in Queenstown Estate, Singapore
To maximize your solar PV system's energy output in Queenstown Estate, Singapore (Lat/Long 1.2958, 103.8025) 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 Queenstown Estate, 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 Queenstown Estate, 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 Queenstown Estate, 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 Queenstown Estate, Singapore.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Queenstown Estate, Singapore
The topography around Queenstown Estate, Singapore is hilly and relatively flat. Areas that are most suited to large-scale solar PV would be the flat areas such as rooftops and open fields. The surrounding hills may also provide good sites for solar PV installations, depending on the angle of inclination and orientation relative to the sun's path.
Singapore solar PV Stats as a country
Singapore ranks 56th in the world for cumulative solar PV capacity, with 433 total MW's of solar PV installed. This means that 0.80% of Singapore's total energy as a country comes from solar PV (that's 37th in the world). Each year Singapore is generating 76 Watts from solar PV per capita (Singapore ranks 42nd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Singapore?
Yes, there are several incentives for businesses wanting to install solar energy in Singapore. The SolarNova Programme provides funding support for the installation of solar photovoltaic (PV) systems on rooftops and other suitable areas. Businesses can also benefit from the Solar Capability Development Grant, which helps them develop their capabilities in solar PV system design and installation. Additionally, businesses may be eligible for tax deductions or exemptions under the Productivity and Innovation Credit Scheme (PIC).
