Solar Energy Potential in Dungun, Terengganu, Malaysia

Dungun, Terengganu, Malaysia, located at latitude 4.8168 and longitude 103.3036, offers promising conditions for solar energy generation throughout the year. This tropical location benefits from relatively consistent sunlight patterns, making it a favorable site for solar PV installations. The seasonal solar energy production shows good consistency across the year. In Spring, the location achieves its highest output at 5.93 kWh per day for each kilowatt of installed capacity. Summer follows closely with 5.59 kWh/day, while Autumn delivers 5.47 kWh/day. Winter sees a slight dip to 4.79 kWh/day, but still maintains reasonable production levels compared to many other global locations. For fixed solar panel installations in Dungun, Terengganu, the ideal tilt angle to maximize year-round energy production is just 3 degrees South. This nearly horizontal orientation reflects Dungun's proximity to the equator, where the sun passes almost directly overhead throughout much of the year.

Environmental Considerations

Several environmental factors could potentially impact solar energy production in Dungun:

• High humidity and frequent rainfall, especially during the monsoon season (typically November to March), can reduce solar efficiency through cloud cover and panel soiling
• Coastal proximity may expose installations to salt spray corrosion and higher humidity
• Tropical vegetation growth can create shading issues if not properly managed

Preventative Measures

To maximize solar energy production in Dungun's tropical environment, several preventative measures should be considered: Installing corrosion-resistant mounting hardware and marine-grade components will help combat the effects of salt air and high humidity. Regular cleaning schedules should be implemented to remove dust, salt deposits, and bird droppings that accumulate on panels, particularly after dry periods. Elevation of panels and strategic placement away from fast-growing vegetation can minimize shading issues. Additionally, investing in microinverters or power optimizers rather than string inverters can help mitigate production losses when partial shading occurs. For large installations, weather monitoring systems can provide advance warning of incoming storms, allowing for protective measures to be taken when necessary. Despite these challenges, Dungun's consistent year-round solar radiation makes it a highly viable location for solar energy production with proper planning and maintenance.

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

Ideally tilt fixed solar panels 3° South in Dungun, Malaysia

To maximize your solar PV system's energy output in Dungun, Malaysia (Lat/Long 4.8168, 103.3036) throughout the year, you should tilt your panels at an angle of 3° 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 Dungun, 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 Dungun, Malaysia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 3° 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	10° 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 Dungun, 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 Dungun, 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 Dungun, Malaysia

Dungun sits along the eastern coastline of Peninsular Malaysia in the state of Terengganu, characterized by a diverse topographical landscape that transitions from coastal plains to inland hills. The immediate coastal area features sandy beaches and low-lying terrain, with elevations generally below 50 meters above sea level. This coastal strip extends several kilometers inland before the landscape begins to rise gradually. Moving westward from the coast, the topography becomes increasingly undulating with rolling hills and small valleys. The western parts of the Dungun district rise into the foothills of the Terengganu highlands, part of the larger Titiwangsa Range that forms the backbone of the Malay Peninsula. These areas reach elevations of 200-400 meters in many places, with some peaks extending higher.

Hydrological Features

The Dungun River (Sungai Dungun) is a prominent feature of the local landscape, flowing eastward to meet the South China Sea. This river system creates fertile valleys and floodplains that have historically supported agriculture in the region. Several smaller streams and tributaries branch throughout the district, creating a network of natural drainage systems.

Vegetation and Land Cover

Natural vegetation in the Dungun area consists primarily of tropical rainforest, though significant portions have been modified for human use. Coastal areas often feature coconut palms and beachfront vegetation adapted to sandy soils and salt spray. Inland areas maintain patches of tropical rainforest, particularly in steeper terrain, while plantation agriculture (primarily oil palm and rubber) occupies many of the gentler slopes and valleys.

Suitable Areas for Solar PV Development

For large-scale solar photovoltaic installations, several aspects of Dungun's topography present favorable conditions: The coastal plains offer extensive flat terrain that would minimize site preparation costs for solar arrays. These areas typically have minimal shading concerns from natural features and good accessibility via existing transportation infrastructure. The relatively low elevation also simplifies construction logistics. Cleared agricultural land, particularly former plantation areas with gentle slopes of less than 5 degrees, presents another opportunity for solar development. These areas have already undergone land conversion, potentially reducing environmental impact and simplifying permitting processes. Some of the rolling hills with south-facing slopes (in the Northern Hemisphere, north-facing slopes would be preferred, but Malaysia's equatorial position means orientation is less critical) could also accommodate solar installations, though these would require more extensive site preparation. Areas to avoid would include the steeper hillsides and mountains to the west, where installation would be technically challenging and environmentally disruptive. Floodplains along the Dungun River should also be avoided due to periodic inundation risks. The northeastern coastal sections of the district, where land meets the South China Sea, combine favorable topography with proximity to existing transmission infrastructure that serves coastal communities. This potentially reduces interconnection costs for new solar facilities while utilizing land that may have fewer competing uses than fertile agricultural valleys.
