Solar PV Analysis of Subang Jaya, Malaysia
Subang Jaya, Selangor, Malaysia, located in the Tropics, is a great location for generating solar energy all year round. This is because it gets consistent sunlight throughout most of the year. The amount of electricity produced each day per kilowatt (kW) of installed solar panels ranges from 5.26 to 5.44 kilowatt-hours (kWh). This means that no matter what season it is - Summer, Autumn, Winter or Spring - you can expect your solar panels to produce a similar amount of electricity each day.
The ideal times to generate solar at this location are during the Summer and Spring seasons when daily production reaches its peak at around 5.39 and 5.44 kWh/day respectively per kW of installed solar.
If you're planning on installing fixed panel installations at this location, tilting them at an angle of 3 degrees towards the South will help maximize total yearly production from your solar photovoltaic system.
However, like any other place in the world, there might be local factors that could affect how much energy you can generate with your panels such as weather conditions and environmental issues. In Subang Jaya's case being located in a tropical region means experiencing wet and dry seasons which could potentially hinder optimal operation occasionally due to cloud cover during wet periods or dust accumulation on panels during drier periods.
To mitigate these challenges:
1) Regular cleaning: Dust particles accumulating on your panels can significantly reduce their efficiency so regular cleaning especially during drier periods would be beneficial.
2) Weatherproofing: It's also important to ensure that your installation is weatherproofed properly to withstand heavy rains typical in tropical regions.
3) Shade Analysis: Before installing make sure there are no nearby structures or trees casting shadows onto the panels which reduces their effectiveness.
4) Quality Equipment: Use high-quality equipment designed for harsh weather conditions common in tropical climates like humidity and heat resistance features.
In conclusion, Subang Jaya is an ideal location for solar energy production all year round with just a few considerations to keep in mind for optimal operation.
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 Subang Jaya
Seasonal solar PV output for Latitude: 3.0501, Longitude: 101.5696 (Subang Jaya, 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 3° South in Subang Jaya, Malaysia
To maximize your solar PV system's energy output in Subang Jaya, Malaysia (Lat/Long 3.0501, 101.5696) 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 Subang Jaya, 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 Subang Jaya, 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 |
|---|---|---|---|
| 13° North in Summer | 9° South in Autumn | 18° South in Winter | 3° 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 Subang Jaya, 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 Subang Jaya, 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 Subang Jaya, Malaysia
Subang Jaya is located in the state of Selangor, Malaysia. The topography here is generally flat with a few hilly areas. It is an urban area with residential, commercial and industrial sectors.
Given that Subang Jaya has limited open land available due to its urban development, large-scale solar PV installations may not be feasible within the city limits. However, there are possibilities for rooftop solar panels on buildings or structures.
In terms of larger scale solar PV projects, nearby less densely populated areas such as the district of Kuala Langat to the south or Hulu Selangor to the north could be more suitable because they have more open land available. These regions also have similar tropical climate conditions as Subang Jaya which are conducive for solar energy generation - high temperatures and good levels of sunlight throughout the year.
However, it's important to note that successful implementation would require careful planning and consideration of factors such as local regulations, potential environmental impacts and grid connectivity among others.
Malaysia solar PV Stats as a country
Malaysia ranks 33rd in the world for cumulative solar PV capacity, with 1,787 total MW's of solar PV installed. This means that 2.40% of Malaysia's total energy as a country comes from solar PV (that's 32nd in the world). Each year Malaysia is generating 55 Watts from solar PV per capita (Malaysia ranks 51st in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Malaysia?
Yes, there are several incentives for businesses wanting to install solar energy in Malaysia. The Malaysian government offers a range of financial incentives and tax breaks for businesses that invest in renewable energy projects. These include the Renewable Energy Fund (REF), which provides grants and loans to support the development of renewable energy projects; the Green Technology Financing Scheme (GTFS), which provides financing for green technology investments; and the Feed-in Tariff (FiT) scheme, which guarantees a fixed price for electricity generated from renewable sources. Additionally, businesses may be eligible for capital allowances on their investments in solar energy systems.
