Putrajaya, Malaysia, situated at 2.9269° N, 101.6971° E, offers a favorable location for solar energy generation throughout the year. This tropical city experiences consistent sunlight, with its seasons characterized more by wet and dry periods rather than traditional temperature-based seasons.

Year-round Solar Energy Potential

The solar energy output in Putrajaya remains relatively stable across all meteorological seasons. Spring sees the highest production at 5.68 kWh per day for each kilowatt of installed solar capacity. This is closely followed by autumn with 5.55 kWh/day, summer with 5.39 kWh/day, and winter with 5.22 kWh/day. These figures demonstrate a minimal variation between seasons, indicating that Putrajaya is an excellent location for consistent solar energy generation throughout the year.

Optimal Panel Tilt

For fixed solar panel installations in Putrajaya, the ideal tilt angle to maximize year-round energy production is 2 degrees South. This nearly flat orientation is due to the city's proximity to the equator, where the sun's path remains relatively high in the sky throughout the year.

Environmental and Weather Considerations

While Putrajaya's location is generally ideal for solar energy production, there are some environmental factors to consider: 1. Rainfall: The region experiences a monsoon season, typically from October to March, which can lead to increased cloud cover and potentially reduced solar output. 2. Haze: Occasional haze events, often caused by regional agricultural burning, can temporarily decrease solar irradiance. To mitigate these factors, consider the following preventative measures when installing solar panels:

Preventative Measures

1. Use high-efficiency panels that perform well in diffuse light conditions. 2. Install a robust cleaning system to remove dust and debris, which can accumulate during dry periods. 3. Implement a monitoring system to track performance and quickly identify any issues caused by environmental factors. 4. Consider adding energy storage solutions to balance out production during periods of reduced sunlight. In conclusion, Putrajaya's tropical location provides an excellent opportunity for year-round solar energy generation, with only minor seasonal variations. By addressing the few environmental challenges through proper system design and maintenance, solar installations in this area can achieve high and consistent energy production.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Solar output per kW of installed solar PV by season in Putrajaya

Seasonal solar PV output for Latitude: 2.9269, Longitude: 101.6971 (Putrajaya, Malaysia), 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 2° South in Putrajaya, Malaysia

To maximize your solar PV system's energy output in Putrajaya, Malaysia (Lat/Long 2.9269, 101.6971) throughout the year, you should tilt your panels at an angle of 2° 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 Putrajaya, Malaysia

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 Putrajaya, Malaysia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 2° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
13° North in Summer	9° South in Autumn	18° South in Winter	3° 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 Putrajaya, Malaysia

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 Putrajaya, Malaysia.

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 Putrajaya, Malaysia

Putrajaya, the planned administrative capital of Malaysia, is situated in a relatively flat area with gentle undulations. The topography around Putrajaya is characterized by low-lying plains and subtle hills, typical of the Klang Valley region. The city itself was built on former oil palm and rubber plantations, which were converted into a modern urban landscape. The surrounding area features a mix of natural and man-made elements. To the north and east of Putrajaya, the terrain gradually rises into low hills covered with tropical vegetation. These hills are part of the larger Titiwangsa Range that runs through peninsular Malaysia. To the south and west, the landscape is predominantly flat, with occasional small hillocks and shallow valleys.

Wetlands and Water Bodies

One of the most prominent features of Putrajaya's topography is its extensive network of man-made lakes and wetlands. The Putrajaya Lake, covering an area of about 650 hectares, is the centerpiece of the city's landscape. This artificial lake, along with several smaller water bodies, not only enhances the aesthetic appeal of the area but also serves important ecological functions.

Suitable Areas for Large-Scale Solar PV

When considering areas nearby Putrajaya for large-scale solar photovoltaic (PV) installations, several factors come into play. The most suitable locations would be: 1. The flat, open areas to the south and west of Putrajaya: These regions offer expansive spaces with minimal shading from natural features, making them ideal for solar farms. The relatively level terrain would simplify installation and reduce costs associated with land preparation. 2. Former agricultural lands: Many areas surrounding Putrajaya were once plantations. These cleared, open spaces could be repurposed for solar energy production, providing an environmentally friendly alternative use for the land. 3. Industrial zones: The nearby industrial areas, particularly those on the outskirts of Putrajaya and neighboring cities like Cyberjaya, often have large, flat rooftops that could be utilized for solar panel installations. 4. Gentle slopes facing south: While less common in the immediate vicinity of Putrajaya, any gently sloping areas that face south would be excellent for maximizing solar exposure throughout the day. It's important to note that while the topography around Putrajaya is generally favorable for solar PV installations, other factors such as local regulations, grid connectivity, and environmental impact assessments would need to be considered for any large-scale solar project in the region.
