Solar PV Analysis of Kajang, Malaysia
Kajang, Selangor, Malaysia is a great location for generating solar energy all year round. This is because it's located in the tropics where sunlight is consistent throughout most of the year. The amount of electricity that can be produced from each kilowatt of installed solar power doesn't change much across seasons - you can expect around 5.39kWh/day in Summer and Autumn, slightly less at 5.26kWh/day in Winter, and a little more at 5.44kWh/day in Spring.
This means that there isn't really an 'ideal' time of year to generate solar power here - it's pretty good all year round! However, if you're installing fixed panel solar systems here, make sure they are tilted at an angle of 2 degrees facing South to get the maximum total yearly production.
As for potential obstacles to producing solar power in Kajang, Selangor, one thing that might affect production could be the weather patterns typical to tropical climates like heavy rainfalls or monsoons which may block sunlight temporarily or cause damage to panels. To prevent this from affecting your energy generation too much, consider installing durable panels capable of withstanding harsh weather conditions and ensure regular maintenance checks especially before and after heavy rainfall seasons.
Also remember that local buildings or trees could potentially cast shadows over your panels so choose your installation site carefully considering these factors as well.
In summary: Kajang offers consistent solar energy production opportunities throughout the year with minimal seasonal variation making it an ideal location for harnessing sun’s energy via PV system installations when done right!
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 Kajang
Seasonal solar PV output for Latitude: 3.0081, Longitude: 101.7719 (Kajang, 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 2° South in Kajang, Malaysia
To maximize your solar PV system's energy output in Kajang, Malaysia (Lat/Long 3.0081, 101.7719) 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 Kajang, 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 Kajang, 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 |
|---|---|---|---|
| 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 Kajang, 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 Kajang, 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 Kajang, Malaysia
Kajang, Malaysia is located in the state of Selangor and features a tropical rainforest climate. The topography of the area is generally flat with some hilly areas. It also has a number of rivers running through it.
For large-scale solar PV installations, open and flat areas are typically most suitable as they provide maximum exposure to sunlight and ease installation process. Given this criteria, rural or less densely populated parts around Kajang could be potential sites for such projects. However, it's important to consider that Malaysia experiences heavy rainfall due to its tropical climate which might affect the efficiency of solar panels.
Additionally, rooftops in urban areas like Kajang town can also be utilized for installing solar panels on a large scale. This would not only save space but will also meet energy needs locally reducing transmission losses.
It should be noted that any decision about where to place these installations should take into account local regulations and environmental impact assessments as well as technical feasibility studies including sun irradiance levels throughout the year.
To determine specific locations would require more detailed geographical data analysis along with other factors such as accessibility, proximity to grid infrastructure etc.
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.
