Pasir Mas, Kelantan, Malaysia, located at 6.0105° N, 102.1393° E, offers a promising environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than significant temperature variations.

Seasonal Solar Performance

Solar panel performance in Pasir Mas varies slightly across the meteorological seasons. Spring stands out as the most productive period, with an impressive 6.48 kWh per day for each kilowatt of installed solar capacity. Summer follows with 5.85 kWh/day, while winter and autumn yield 5.39 kWh/day and 5.02 kWh/day, respectively. These figures indicate that Pasir Mas maintains strong solar potential year-round, with only modest fluctuations between seasons. The relatively high output during winter is particularly noteworthy, as many locations experience significant drops in solar production during colder months.

Optimal Panel Positioning

For fixed solar panel installations in Pasir Mas, Kelantan, the ideal tilt angle to maximize year-round energy production is 5 degrees facing South. This slight tilt helps optimize sunlight capture throughout the year, accounting for the location's proximity to the equator and the Earth's elliptical orbit.

Environmental Considerations

While Pasir Mas offers favorable conditions for solar energy generation, there are some environmental factors to consider: 1. Rainfall: The region experiences a monsoon season, typically from November to March, which may lead to increased cloud cover and potentially reduced solar output. 2. Humidity: High humidity levels can slightly decrease panel efficiency and may contribute to faster degradation of equipment over time. To mitigate these factors, consider the following preventative measures:

• Use high-quality, weather-resistant solar panels and components designed for tropical climates.
• Implement a regular cleaning schedule to remove dust and debris, which can accumulate more quickly in humid environments.
• Install a robust mounting system to withstand potential strong winds during monsoon seasons.

Despite these considerations, Pasir Mas remains an excellent location for solar energy production. With its consistent sunlight and relatively stable seasonal performance, solar PV systems in this area can provide reliable and substantial energy output throughout the year.

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 Pasir Mas

Seasonal solar PV output for Latitude: 6.0105, Longitude: 102.1393 (Pasir Mas, 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 Pasir Mas, Malaysia

To maximize your solar PV system's energy output in Pasir Mas, Malaysia (Lat/Long 6.0105, 102.1393) 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 Pasir Mas, 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 Pasir Mas, 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
10° North in Summer	11° 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 Pasir Mas, 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 Pasir Mas, 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 Pasir Mas, Malaysia

Pasir Mas, located in the state of Kelantan, Malaysia, is situated in a predominantly flat and low-lying area. The topography of the region surrounding Pasir Mas is characterized by expansive plains and gentle undulations, with occasional areas of slightly elevated terrain. This landscape is largely influenced by the presence of the Kelantan River, which meanders through the area, shaping the local geography over millennia. The immediate vicinity of Pasir Mas consists mainly of agricultural land, with rice paddies and small plantations dominating the scenery. These flat, open spaces extend for considerable distances, interrupted only by scattered rural settlements and occasional patches of vegetation. As one moves further from the town center, the terrain remains relatively consistent, with minimal changes in elevation.

Potential 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 flat topography of the region surrounding Pasir Mas presents a significant advantage for solar energy development. Large, unobstructed areas are ideal for maximizing solar exposure and simplifying the construction and maintenance of solar arrays. The agricultural lands to the north and east of Pasir Mas offer promising potential for solar PV projects. These areas benefit from minimal shading and have already been cleared for cultivation, reducing the environmental impact of repurposing the land. Additionally, the proximity to existing infrastructure and power grids in Pasir Mas could facilitate easier integration of solar-generated electricity into the local energy network. However, it's important to note that the region's susceptibility to flooding, particularly during the monsoon season, should be carefully considered when planning large-scale solar installations. Areas slightly elevated above the flood plains, such as gentle slopes or higher ground to the west of Pasir Mas, might offer more suitable locations for solar PV development. These areas would provide better protection against potential water damage while still benefiting from the region's abundant sunlight. In conclusion, while the flat topography around Pasir Mas generally favors solar PV development, careful site selection is crucial to balance optimal sun exposure with protection against environmental risks. The most suitable areas would likely be those that combine the advantages of the region's flat terrain with slightly elevated positions to mitigate flooding concerns.
