Which Part Of Malaysia Is Best For Solar Energy?

Malaysia is located in an average region when come to solar installation. Even though it is situated very near to the equator, high percentage of cloudy and rainy day has blocked sunlight to reach the ground. Below picture shows the global solar radiation map. Clearly can see that Malaysia is just having an average amount of solar radiationy.

Even within Malaysia, the amount of solar energy received varies from place to place. The variation can range up to 25%.

So, where is the best location for solar installation in Malaysia?

The answer is "northern part of Malaysia"! According to the data published by Photovoltaic Monitoring Centre of Universiti Teknology MARA, the best location is Kudat which receives 1979.9 kWh/m2 of solar energy annually.

If we install 1 kW of solar system each in Kuala Lumpur and Kudat, the system in Kudat will receive about 25% more of energy than the one in Kuala Lumpur. This means Kudat will have a shorter system payback time than Kuala Lumpur.
