Bukit Mertajam, Penang, Malaysia, situated at 5.3323° N, 100.4645° E, offers a promising location for solar energy generation. This tropical area experiences consistent sunlight throughout the year, with seasons characterized more by wet and dry periods rather than traditional temperature-based seasons.

Solar Energy Production Potential

The solar energy potential in Bukit Mertajam is relatively stable across all meteorological seasons. Spring sees the highest production 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 substantial outputs at 5.44 kWh/day and 5.19 kWh/day, respectively. These figures indicate that Bukit Mertajam is an excellent location for year-round solar energy generation. The consistent output across seasons means that solar installations can provide reliable power throughout the year, with only minor fluctuations in production.

Optimal Panel Tilt

For fixed panel installations in Bukit Mertajam, Penang, the ideal tilt angle to maximize year-round solar production is 5 degrees facing South. This relatively low tilt angle is due to the location's proximity to the equator, where the sun's path is more directly overhead throughout the year.

Environmental and Weather Considerations

While Bukit Mertajam's tropical climate is generally favorable for solar energy production, there are some factors to consider: 1. Rainfall: The region experiences a monsoon season, which can lead to increased cloud cover and rainfall, potentially reducing solar output during these periods. 2. Humidity: High humidity levels can slightly decrease panel efficiency and may lead to increased maintenance needs due to moisture-related issues. To mitigate these factors, consider the following preventative measures when installing solar panels:

• Use high-quality, weather-resistant panels designed for tropical climates
• Implement proper drainage systems to prevent water accumulation on panels
• Schedule regular cleaning and maintenance to combat the effects of humidity and rainfall
• Consider incorporating micro-inverters or power optimizers to minimize the impact of partial shading from cloud cover

Despite these considerations, Bukit Mertajam remains an ideal location for solar energy production. The consistent year-round sunlight and relatively minor seasonal variations in output make it a prime candidate for solar PV installations, offering the potential for substantial and reliable clean energy generation.

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 Bukit Mertajam

Seasonal solar PV output for Latitude: 5.3323, Longitude: 100.4645 (Bukit Mertajam, 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 Bukit Mertajam, Malaysia

To maximize your solar PV system's energy output in Bukit Mertajam, Malaysia (Lat/Long 5.3323, 100.4645) 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 Bukit Mertajam, 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 Bukit Mertajam, 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 Bukit Mertajam, 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 Bukit Mertajam, 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 Bukit Mertajam, Malaysia

Bukit Mertajam, located in Penang, Malaysia, is characterized by a diverse topography that combines flat lowlands with hilly terrain. The area around the given coordinates (5.3323, 100.4645) is primarily dominated by the prominent Bukit Mertajam Hill, which rises to an elevation of approximately 545 meters (1,788 feet) above sea level. This hill is a distinctive landmark in the region and forms part of a larger hilly area that extends to the east and northeast.

The immediate surroundings of Bukit Mertajam feature a mix of gently rolling hills and flat plains. To the west and southwest of the hill, the terrain gradually flattens out into a more level landscape. This area transitions into the coastal plains that stretch towards the Strait of Malacca. The eastern and southeastern parts of the region maintain a slightly more undulating topography, with smaller hills and valleys interspersed throughout.

For large-scale solar PV installations, the most suitable areas would likely be found in the flatter regions to the west and southwest of Bukit Mertajam. These areas offer several advantages for solar energy development:

1. The relatively level terrain makes construction and installation of solar panels easier and more cost-effective.
2. There are fewer natural obstacles that could cast shadows on the panels, maximizing sun exposure throughout the day.
3. The proximity to existing infrastructure and urban areas could facilitate easier grid connection and maintenance.

However, it's important to note that the specific suitability of any site for solar PV would require detailed on-the-ground assessments. Factors such as local land use, environmental considerations, and proximity to transmission infrastructure would all play crucial roles in determining the most appropriate locations for large-scale solar developments in the region surrounding Bukit Mertajam.
