Kangar, Perlis, Malaysia, situated at coordinates 6.4312, 100.2048, offers a promising location for solar energy generation throughout the year. This tropical city experiences consistent sunlight, with seasons primarily characterized by wet and dry periods rather than traditional temperature-based seasons.

Year-round Solar Potential

The solar energy output in Kangar remains relatively stable across all meteorological seasons. Spring sees the highest production at 6.09 kWh per day for each kW of installed solar capacity. Winter follows closely with 5.57 kWh/day, while summer yields 5.42 kWh/day. Autumn experiences a slight dip but still maintains a respectable 4.97 kWh/day. These figures indicate that Kangar is an excellent location for solar PV installations, with consistent energy production throughout the year. The spring months offer the most favorable conditions for solar generation, making it an ideal time for maintenance or system upgrades.

Optimal Panel Tilt

For fixed solar panel installations in Kangar, Perlis, the ideal tilt angle to maximize year-round production is 6 degrees facing South. This shallow angle reflects the city's proximity to the equator, where the sun's path remains relatively high in the sky throughout the year.

Environmental Considerations

While Kangar'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 efficiency. 2. Dust and pollution: Tropical environments can accumulate dust and airborne particles on solar panels, affecting their performance. To mitigate these issues, consider the following preventative measures:

• Install panels with anti-reflective coatings to improve performance in high humidity.
• Implement a regular cleaning schedule to remove dust and debris from panels.
• Use weather-resistant mounting systems to protect against corrosion in the humid climate.
• Consider microinverters or power optimizers to minimize the impact of partial shading from clouds.

By addressing these factors, solar installations in Kangar can maintain high efficiency and capitalize on the location's excellent year-round solar potential.

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 77 locations across Malaysia. 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 Kangar

Seasonal solar PV output for Latitude: 6.4312, Longitude: 100.2048 (Kangar, 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 6° South in Kangar, Malaysia

To maximize your solar PV system's energy output in Kangar, Malaysia (Lat/Long 6.4312, 100.2048) throughout the year, you should tilt your panels at an angle of 6° 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 Kangar, 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 Kangar, Malaysia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 6° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
10° North in Summer	12° South in Autumn	21° South in Winter	0° 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 Kangar, 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 Kangar, 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 Kangar, Malaysia

The topography around Kangar, Malaysia, located at 6.4312°N latitude and 100.2048°E longitude, is characterized by a diverse landscape that combines flat lowlands with gently rolling hills. Kangar, the capital of Perlis state, sits in a relatively flat area near the coast of the Strait of Malacca. The surrounding region features a mix of agricultural plains, scattered hills, and some forested areas. To the east of Kangar, the terrain gradually becomes more undulating, with low hills and small valleys dotting the landscape. These hills are typically covered in lush vegetation, owing to the tropical climate of the region. As one moves further east, the terrain becomes more pronounced, eventually leading to the Titiwangsa Mountains, which form the backbone of Peninsular Malaysia. To the west and northwest of Kangar, the land is predominantly flat, consisting of coastal plains and agricultural fields. This area is part of the larger alluvial plain that extends along much of Malaysia's western coast. The flat terrain in this direction continues across the border into southern Thailand.

Areas Suitable for Large-scale Solar PV

When considering areas near Kangar that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would have ample sunlight exposure, relatively flat terrain, and minimal environmental impact. The coastal plains to the west and northwest of Kangar present promising opportunities for solar PV development. These areas benefit from consistent sunlight exposure and flat terrain, which simplifies installation and maintenance of solar panels. Additionally, many of these regions are already used for agriculture, potentially allowing for dual-use solar farms that combine energy production with crop cultivation. Some of the gently rolling hills to the east of Kangar could also be suitable for solar PV installations. While not as flat as the coastal plains, these areas still offer good sun exposure and may have fewer competing land uses. However, care would need to be taken to minimize environmental impact and preserve forested areas. It's worth noting that any large-scale solar PV project would require careful environmental and social impact assessments. Factors such as proximity to existing power infrastructure, local weather patterns, and land ownership would also play crucial roles in determining the most suitable locations for solar energy development in the region around Kangar.
