Alor Gajah, Melaka, Malaysia, located in the tropics at latitude 2.2982 and longitude 102.2824, offers a promising environment for solar energy production throughout the year. The region experiences consistent sunlight, with seasons characterized more by wet and dry periods rather than traditional temperature-based seasons.
Year-round Solar Energy Potential
The solar energy potential in Alor Gajah remains relatively stable across all meteorological seasons. Spring sees the highest output at 5.59 kWh per day for each kilowatt of installed solar capacity, followed closely by autumn at 5.46 kWh/day. Summer and winter show slightly lower but still substantial outputs of 5.16 kWh/day and 5.18 kWh/day, respectively.
This consistency in solar energy production throughout the year makes Alor Gajah an ideal location for solar PV installations. The minimal variation between seasons ensures a reliable energy supply, reducing the need for supplementary power sources during specific times of the year.
Optimal Panel Tilt Angle
For fixed panel installations in Alor Gajah, Melaka, the ideal tilt angle to maximize year-round solar production is 2 degrees South. This slight tilt helps optimize energy capture throughout the year, taking into account the location's proximity to the equator and the sun's position in the sky.
Environmental and Weather Considerations
While Alor Gajah's tropical climate is generally favorable for solar energy production, there are some factors to consider:
- Heavy rainfall during the monsoon season (typically October to March) may temporarily reduce solar output.
- High humidity levels can lead to increased dust accumulation on panels, potentially affecting efficiency.
To mitigate these issues, consider implementing the following measures:
- Install panels at a slightly steeper angle to promote natural cleaning during rainfall.
- Use anti-soiling coatings on panels to reduce dust accumulation.
- Implement a regular cleaning schedule, especially during drier periods.
- Choose high-quality, weather-resistant panels designed for tropical climates.
Overall, Alor Gajah presents an excellent opportunity for solar energy production, with consistent year-round output and manageable environmental challenges that can be addressed through proper installation and maintenance practices.
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 2° South in Alor Gajah, Malaysia
To maximize your solar PV system's energy output in Alor Gajah, Malaysia (Lat/Long 2.2982, 102.2824) 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 Alor Gajah, 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 Alor Gajah, 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 |
|---|---|---|---|
| 14° North in Summer | 8° South in Autumn | 17° South in Winter | 4° 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 Alor Gajah, 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 Alor Gajah, 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 Alor Gajah, Malaysia
The area surrounding Alor Gajah, Malaysia, is characterized by a diverse and gently undulating landscape. Located in the state of Melaka, this region features a mix of low-lying plains, rolling hills, and scattered patches of tropical vegetation. The terrain gradually rises from the coastal areas in the west towards the inland regions, creating a subtle elevation change across the landscape. Alor Gajah itself sits at a relatively low elevation, with the surrounding areas consisting of a patchwork of agricultural lands, small forests, and residential developments. The topography is generally favorable for human settlement and various land uses, with few extreme elevation changes or challenging terrain features.
Suitable Areas for Large-Scale Solar PV
When considering locations for large-scale solar photovoltaic (PV) installations near Alor Gajah, several factors come into play. The most suitable areas would typically be those with ample flat or gently sloping land, good sun exposure, and minimal shading from natural or man-made structures. The agricultural plains to the north and east of Alor Gajah present promising opportunities for solar PV development. These areas often feature expansive, open fields with few obstructions, allowing for optimal sunlight exposure throughout the day. The relatively flat terrain in these regions would also simplify the installation process and reduce construction costs. Another potentially suitable location would be the slightly elevated areas to the southeast of Alor Gajah. These higher grounds might benefit from increased sun exposure and reduced risk of flooding, which could be advantageous for long-term solar infrastructure. It's important to note that while the topography around Alor Gajah is generally favorable for solar PV installations, other factors such as land ownership, proximity to power infrastructure, and environmental considerations would also play crucial roles in determining the most appropriate sites for large-scale solar projects. Additionally, local regulations and zoning laws would need to be carefully considered before any development could take place.Malaysia solar PV Stats as a country
