In Ipoh, Perak, Malaysia (latitude: 4.6162, longitude: 101.086), the tropical climate and consistent sunlight make it a suitable location for generating solar power throughout the year. The average daily energy production per kW of installed solar capacity in each season is as follows: 5.58 kWh in Summer, 5.30 kWh in Autumn, 5.07 kWh in Winter, and 5.69 kWh in Spring.
For a fixed panel installation at this location, the ideal angle to tilt the panels is 4 degrees South to maximize energy production.
It is important to note that occasional heavy rain or strong winds may impact solar power generation at this site. To mitigate these factors and ensure greater energy production, it is recommended to install durable panels with weather-resistant materials and secure mounting structures that can withstand such conditions.
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 Ipoh
Seasonal solar PV output for Latitude: 4.6162, Longitude: 101.086 (Ipoh, 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 4° South in Ipoh, Malaysia
To maximize your solar PV system's energy output in Ipoh, Malaysia (Lat/Long 4.6162, 101.086) throughout the year, you should tilt your panels at an angle of 4° 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 Ipoh, 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 Ipoh, Malaysia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 4° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 12° North in Summer | 10° South in Autumn | 19° South in Winter | 2° 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 Ipoh, 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 Ipoh, 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 Ipoh, Malaysia
The topography around Ipoh, Malaysia is generally hilly and mountainous. Areas with flat terrain such as valleys, plains, and open fields would be most suited to large-scale solar PV installations. The nearby towns of Batu Gajah, Kampar, and Tapah are all situated in relatively flat areas that could be suitable for solar PV projects. Additionally, the nearby hillsides may also provide some potential sites for solar installations if they have sufficient access to sunlight.
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.
