Solar Panels Installation in Malaysia

Updated: Feb 3

Worldwide emissions of CO2 from burning fossil fuels for energy generation stand at 33 billion tons per year. CO2 is the primary greenhouse gas emitted through human activities. These gases trap infrared radiation from the sun as a form of heat, too much of it, as we know it, increase the global average temperature, resulting in extreme weather and melting of polar ice caps, subsequently resulting in higher sea levels flash floods in unimaginable levels as seen in our country, Malaysia, in December 2021 which displaced more than 71,000 residents. Before the industrial revolution, earth’s CO2 concentration was about 288ppm. This value has passed 400ppm. Many scientists have pegged 450ppm as a red line, while others claimed 350ppm as the safe upper limit.


There is a need for clean and renewable energy, and the need is now. Solar power is a clean and inexhaustible resource and does not cause any climate and environmental damage. Solar power is harvested using photovoltaic panels. These panels absorb sunlight, and the energy creates electrical charges that flow through the system and to be readily utilized by homes and businesses. Installing solar panels in Malaysia proves to be a great financial investment, with the government introducing many incentives for its people as an ongoing effort to push the adoption of solar power generation in the country and high solar irradiance provides great ROI for homeowners. Interested in installing solar panels for your home? Let’s take a deep dive into how you can achieve this.


DIY solar panel installation for a house would make sense to you in the get-go, but bear in mind that many factors has to be taken into consideration. From different types of panels to permits and approvals from government bodies. The 5 big steps in installing your home solar system are: determining the system size, purchasing the necessary equipment, installation of panels, wiring, and the installation of your inverter. It is possible to do it but solar panels in Malaysia are not sold to the general public, you could end up forking a larger sum of money for all the necessary equipment for your house. A DIY solar panel installation may void the insurance policy for your home, as you are not a licensed solar engineer nor an electrician. In the long run, it makes more sense to contract a local, yet reputable solar company to assist you in powering your house with green energy.

A typical solar system for your home could cost anywhere from RM 24,000 to RM 48,000 depending on the size of your system. As a smart consumer, you should approach different solar PV service providers for quotations but be wary to not fall for prices that are too good to be true. In most cases, these solar PV service providers cut costs where they can in your system. From using lower grade or even refurbished solar panels that wouldn’t last as long as you think they would, to low-grade electrical cables that deteriorate and turns powdery when exposed to harmful UV rays from the sun for prolonged periods. These factors have a direct impact on one return on investment and system lifetime cost. Hopefully, by now you are convinced on hiring a solar contractor for your home, let’s move on to the few steps one has to make after selecting your contractor.


Step 1

To install solar panels, you have to choose the right type of solar panel for a house.

There are 3 types of panels to choose from:

  • Monocrystalline,

  • Polycrystalline, and

  • Thin Film Solar Panels

With monocrystalline being most used as it offers the highest efficiency rating at 20+%. accessible energy systems for convenient utilisation.


Step 2

Conduct a site survey with an engineer sent by your solar contractor.

This licensed engineer will evaluate your current electrical system and your current usage to best determine the system size requirements. On top of that, the engineer is also required to inspect the condition of your roof. This is to ensure that your home is structurally stable to withstand the weight of the installed solar panels. Another mistake inexperienced individuals might make is not taking shadowing when designing a solar system into account. The engineer can best determine the location, and mounting angle of the panel to make sure that the panels are operating at its peak performance, delivering the maximum amount of energy to your home.

Step 3:

Secure the right permits on solar panel installation for your house from different government bodies.

Including Net Metering (NEM) and permits from Suruhanjaya Tenaga (ST). These documents are to make sure your solar installation is legal and meets all safety requirements by the government. But here’s the good news, all these headaches are handled by your solar contractor. The application approval process could take up to 3-4 weeks for a typical home system, assuming everything is in order


Step 4: Your solar contractor will order all the necessary equipment upon successful approval of the permits and paperwork.

These include the panels, inverters, electrical wiring, mounting system as well as nuts and bolts. You would have chosen the type of panel and inverter prior to signing any contract with the contractor. Your solar contractor should provide you with multiple options, to best suit your solar needs.


Finally we get to the installation phase. Solar panel installation process is quick and simple. Construction workers work diligently, ensuring the panels are mounted according to the rules and safety regulations, especially for it to be able to withstand strong winds “tearing” off the panels from the structure. After installation, electrical wiring is done and signed off by a licensed GCPV engineer and wireman to make certain of correct wiring with no threat to one’s safety.

Step 5: Connect your home solar system to the inverter, which is then connected to the existing power grid.

During the daytime, when there is sufficient sunlight, the inverters are powered up automatically by the panels and start to supply electricity to your house. Most inverters have a display that shows the current electricity generation. As night falls, there is insufficient voltage to power on the inverter and your house starts to use energy supplied by the grid.


Solar energy is one of the most important energy sources in the world with increased attention throughout the recent years as the public is more aware of the effects of global warming and the role renewable energy plays in reducing the effects. Solar energy is experiencing astonishing growth. With lower costs and improvements in technology, increasing numbers of people are adopting solar systems in their homes and businesses.
