The location at Tampines New Town, Singapore is a good spot for generating energy via solar panels all year round. This is because it's located in the tropics where sunlight is quite consistent throughout the year. On average, you can expect to generate around 4.77kWh/day per kW of installed solar in summer, 5.08kWh/day in autumn, 5.01kWh/day in winter and 5.41kWh/day in spring.

The best times of the year to generate solar power at this location are during autumn and spring when daily generation rates are slightly higher compared to other seasons.

For a fixed panel installation at this location, tilting your panels at an angle of 1 degree facing south would give you the most amount of sunlight exposure across all seasons.

However, there could be some local factors that might affect your solar production such as environmental or weather conditions like heavy rainfall or cloud cover during wet seasons which might reduce sunlight exposure on your panels and hence lower energy production.

Also depending on how built-up or hilly the area around Tampines New Town is, nearby buildings or trees could potentially cast shadows over your panels especially if they are not mounted high enough above ground level.

To ensure greater energy production despite these potential challenges:

1) You can consider installing adjustable tilt mounts for your panels so that their angles can be adjusted seasonally to optimise sun exposure.
2) Ensure regular maintenance checks on your system especially after heavy rains or storms to check for any dirt build-up or damages which might reduce panel efficiency.
3) If possible try to install your system away from tall obstructions like buildings/trees that might cast shadows over it.
4) Consider investing in more efficient types of solar cells/panels which work better under less ideal light conditions.
5) Utilise battery storage systems so excess power generated during peak sunny hours can be stored and used when sun exposure is not optimal.

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 Tampines New Town

Seasonal solar PV output for Latitude: 1.3579, Longitude: 103.9429 (Tampines New Town, 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:

Average 4.77kWh/day in Summer.

Average 5.08kWh/day in Autumn.

Average 5.01kWh/day in Winter.

Average 5.41kWh/day in Spring.

Ideally tilt fixed solar panels 1° South in Tampines New Town, Singapore

To maximize your solar PV system's energy output in Tampines New Town, Singapore (Lat/Long 1.3579, 103.9429) 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.

At Latitude: 1.3579, Longitude: 103.9429, the ideal angle to tilt panels is 1° South

Seasonally adjusted solar panel tilt angles for Tampines New Town, 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 Tampines New Town, Singapore. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 1° South tilt angle throughout the year.

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 Tampines New Town, 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 Tampines New Town, 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 Tampines New Town, Singapore

Tampines New Town, Singapore is located in a relatively flat area with an average elevation of only 15 meters above sea level. The terrain is largely urbanized with high-rise residential buildings and commercial establishments, as well as some open spaces like parks.

For large-scale solar PV installations, the most suitable areas would be open spaces that receive plenty of sunlight and have minimal obstructions. In the case of Tampines New Town, rooftops of high-rise buildings could potentially be utilized for solar panel installation due to their ample sun exposure.

Additionally, there are several other potential locations for large-scale solar PV around Tampines including industrial areas such as the Tampines Industrial Park and Changi Business Park which have larger rooftop spaces or open grounds.

However, it's important to note that implementing large-scale solar PV projects in densely populated urban areas like Tampines can pose challenges due to space constraints and potential shading from surrounding buildings. Therefore detailed feasibility studies will need to be conducted before any project implementation.

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).
