How Does the Solar PV System Work?

Updated: May 18, 2023

In recent years, there has been a marked rise in the adoption of solar energy. With growing awareness and concern about the impact of human activities on the environment coupled with the need for cost-effective energy sources, solar energy has emerged as a practical alternative.

In this article, we will explore the workings of a solar photovoltaic (PV) system in detail, including its crucial components and the benefits that accrue from its installation. Furthermore, we will outline the steps to effectively switch to solar energy and provide valuable insights on finding a reputable solar provider in Malaysia.

What is a Solar PV System?

A solar PV system, also known as solar photovoltaic, is a system of interconnected solar panels that convert sunlight into electricity. The electrical energy produced by the solar PV system can proficiently supply power to residences, commercial and industrial buildings, as well as manufacturing plants. Solar PV systems offer a cost-effective and dependable approach to power generation, capable of reducing both energy costs and carbon emissions. Furthermore, through the application of advanced technology such as energy storage systems, solar energy can be conveniently stored for future use.

The Components of a Solar PV System

A solar PV system consists of several components, which work together to generate electricity. These components may include:

  • Photovoltaic (PV) panels These are the main component of a solar PV system and are made up of layers of semiconductor materials such as silicon, which absorb the energy from the sun and convert it into direct current (DC) electricity.

  • Inverter This is a device that converts the DC electricity from the PV panels into alternating current (AC) electricity, which can be used to power homes and buildings.

  • Charge controller This is an electronic device that regulates the flow of electricity from the PV panels to the battery to prevent overcharging.

  • Other components Other components such as batteries and mounting systems are used to store the electricity generated by the system for later use and to secure the solar panels to the roof or the ground.

The key component which converts sunlight into electrical energy is the solar photovoltaic (PV) panel or PV module. These modules can be used individually or with multiple panels in parallel to form arrays. These arrays are then connected to the TNB grid to complete a PV system.

To power homes and businesses, the direct-current (DC) electricity produced by the modules is converted into alternating-current (AC) electricity using an inverter, which is another important component of the system.

If your solar system has been approved by TNB as a self-consumption solar system, any excess electricity generated from the solar PV system can be sold back to the TNB grid.

Benefits of Solar Installation

Solar installation in Malaysia offers numerous benefits, with three key benefits being:

Reduced electricity bills

Installing solar panels can significantly decrease your electricity bills by utilising electricity generated from the Sun. This is especially beneficial in Malaysia, where electricity tariffs are among the highest in the region and are subjected to TNB’s ICPT mechanism.

Environmental sustainability

Solar energy is a clean and renewable energy source, which means that it does not produce harmful emissions or contribute to climate change. By installing solar panels, you can reduce your carbon footprint and promote environmental sustainability.

Return on investment

Solar panel installation is a long-term investment that can provide significant returns over time. With the fact that solar panels can last for up to 25 years or more, you can potentially save thousands of Ringgit on electricity bills over the lifespan of the system. Additionally, the Malaysian government offers incentives such as the Net Energy Metering (NEM) scheme, which allows solar panel owners to sell excess energy back to the grid and earn credits on their electricity bills.

Solar Panel Installation in Malaysia

Switching to solar energy in Malaysia can be a wise decision, as it not only helps to reduce carbon emissions but also offers the potential for significant long-term cost savings on electricity bills. Here are the necessary steps to install solar panels in Malaysia and effectively transition to clean energy:

Conduct a feasibility study

Before making the switch to solar energy, it is essential to carry out a feasibility study to determine if your home or business is suitable for solar installation. This study should include an assessment of your location, available roof space, orientation, and shading.

Calculate your energy consumption

It is crucial to evaluate your current energy consumption to ensure that the solar power system is appropriately sized to meet your energy needs. A reputable solar provider can help with this calculation.

Select a solar provider

It is vital to choose a reputable and experienced solar provider who can guide you through the installation process and provide reliable ongoing support.

Installation and permits

The next step involves installing solar panels and obtaining any necessary permits. It is crucial to engage a licensed and accredited solar installer to ensure that the installation meets all safety and quality standards.

Connection to the grid

After the installation, the solar power system needs to be connected to the grid. Your solar provider can assist with this process.

Monitoring and maintenance

Once the system is operational, regular monitoring and maintenance are necessary to ensure optimal performance and longevity. Your solar provider can offer maintenance services and guidance on best practices for system upkeep.


Tips to Find Reputable Solar Providers in Malaysia

Finding a reputable solar provider in Malaysia is an important step in ensuring a successful solar panel installation. Here are some tips on how to find a reputable provider:

  • Check for licensing and accreditation: Look for solar providers that are licensed by the Sustainable Energy Development Authority (SEDA) and accredited by Malaysian Investment Development Authority (MIDA). These accreditations ensure that the provider meets the necessary standards for safety, quality, and performance.

  • Look for experience and expertise: Choose a provider with experience in solar panel installation, as this demonstrates their expertise and ability to deliver a successful installation. You can also check for reviews and testimonials from previous customers to gauge their level of satisfaction with the provider's services.

  • Evaluate their product offerings: Check the provider's product offerings and ensure that they offer high-quality and reliable components, such as solar panels, inverters, and batteries. High-quality components can ensure that your solar panel system performs optimally and lasts for its expected lifespan.

  • Compare prices and services: Get multiple quotes from different solar providers and compare the prices and services offered. However, it is important to note that the cheapest provider may not always be the best option, as quality and reliability should also be considered.

  • Check their after-sales service and warranty: Ensure that the provider offers after-sales services, such as maintenance and repair, to ensure that your solar panel system continues to perform optimally. Additionally, check the warranty offered on the components and installation to ensure that you are covered in case of any issues.
