Tasek Gelugor, Penang, Malaysia, situated in the tropics, presents a promising location for solar energy generation throughout the year. This area experiences consistent sunlight, with seasons primarily characterized by wet and dry periods rather than traditional temperature-based seasons.
Year-round Solar Performance
The solar energy potential in Tasek Gelugor remains relatively stable across all meteorological seasons. Spring sees the highest output at 5.95 kWh per day for each kilowatt of installed solar capacity, followed closely by winter at 5.75 kWh/day. Summer and autumn show slightly lower but still impressive outputs of 5.44 kWh/day and 5.19 kWh/day, respectively. These figures indicate that Tasek Gelugor is an excellent location for solar PV installations, with strong performance throughout the year. The minimal variation between seasons suggests that solar energy systems in this area can provide a consistent and reliable power supply.Optimal Panel Placement
For fixed panel installations in Tasek Gelugor, Penang, the ideal tilt angle to maximize year-round solar production is 5 degrees facing South. This relatively low tilt angle is typical for locations near the equator, where the sun's path stays high in the sky throughout the year.Environmental Considerations
While Tasek Gelugor's tropical climate is generally favorable for solar energy production, there are some environmental factors to consider: 1. High humidity and rainfall: The region's wet seasons can lead to increased cloud cover and rainfall, potentially reducing solar output. 2. Dust and particulate matter: Agricultural activities and industrial processes in the area may contribute to air pollution, which can accumulate on solar panels and decrease efficiency. To mitigate these challenges, consider the following preventative measures:- Install a reliable cleaning system or schedule regular manual cleaning to remove dust and debris from solar panels.
- Use anti-soiling coatings on panels to reduce dust accumulation and make cleaning easier.
- Implement a slight increase in panel tilt angle (beyond the optimal 5 degrees) to promote natural cleaning by rainfall.
- Choose high-quality, weather-resistant solar panels designed to perform well in humid, tropical conditions.
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 Tasek Gelugor
Seasonal solar PV output for Latitude: 5.368, Longitude: 100.3039 (Tasek Gelugor, 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 5° South in Tasek Gelugor, Malaysia
To maximize your solar PV system's energy output in Tasek Gelugor, Malaysia (Lat/Long 5.368, 100.3039) throughout the year, you should tilt your panels at an angle of 5° 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 Tasek Gelugor, 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 Tasek Gelugor, Malaysia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 5° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 11° North in Summer | 11° South in Autumn | 20° South in Winter | 1° 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 Tasek Gelugor, 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 Tasek Gelugor, Malaysia.
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 Tasek Gelugor, Malaysia
The area surrounding Tasek Gelugor, Malaysia, is characterized by a diverse topography that reflects the region's geological history and human influence. Located in the northwestern part of Peninsular Malaysia, this area features a mix of low-lying coastal plains and gently rolling hills. Near the coast, which is approximately 10 kilometers to the west of Tasek Gelugor, the terrain is predominantly flat and low-lying. This coastal plain is part of the larger Kedah-Perlis Plain, known for its fertile soil and extensive rice cultivation. The land here is generally less than 10 meters above sea level, with numerous irrigation canals and small rivers crisscrossing the landscape. As one moves inland and slightly eastward from Tasek Gelugor, the topography gradually transitions to more undulating terrain. Here, small hills and ridges begin to emerge, creating a patchwork of elevated areas interspersed with shallow valleys. These hills typically range from 20 to 100 meters in height, offering a gentle contrast to the flatlands near the coast. Further east, about 15 to 20 kilometers from Tasek Gelugor, the landscape becomes more pronounced with higher hills and steeper slopes. This area marks the beginning of the central mountain range that runs through the spine of Peninsular Malaysia. However, compared to the more mountainous regions further inland, these hills are still relatively modest in elevation, rarely exceeding 300 meters.
Suitability for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would combine favorable topography with practical considerations such as land availability and proximity to existing infrastructure. The flat coastal plains to the west of Tasek Gelugor present promising opportunities for solar PV development. These areas offer large, unobstructed spaces that receive ample sunlight throughout the year. The lack of significant elevation changes makes construction and maintenance easier. However, potential flooding risks and competition with agricultural land use should be carefully evaluated. The gently rolling hills to the east and southeast of Tasek Gelugor also show potential for solar PV installations. These slightly elevated areas may benefit from reduced flood risk and could potentially capture more sunlight due to their sloped surfaces. The varied topography might allow for creative panel arrangements to maximize energy capture. It's important to note that while the hilly regions further east may seem attractive due to their elevation, the steeper slopes and more complex terrain could increase installation costs and complicate maintenance procedures. Additionally, these areas might have more vegetation cover, which would need to be cleared, potentially raising environmental concerns. Ultimately, the most suitable areas for large-scale solar PV near Tasek Gelugor would likely be found in the transition zones between the coastal plains and the beginning of the hilly regions. These areas could offer a balance of favorable topography, adequate land availability, and reasonable proximity to existing power infrastructure, making them prime candidates for solar energy development in the region.Malaysia solar PV Stats as a country
