Solar power is one of the most promising renewable energy sources, and it’s gaining traction in Malaysia thanks to the country’s abundant sunshine. But what exactly is solar power, and how does it work? Let’s dive in!
How Does Solar Power Work?
Solar power begins with the sun. Solar panels, also known as photovoltaic (PV) panels, generate electricity by absorbing sunlight through their photovoltaic cells. These cells convert sunlight into direct current (DC) electricity, which is then transformed into alternating current (AC) electricity using an inverter. This AC electricity can power your home, business, or even be fed back into the grid.
The term “solar PV” comes from the photovoltaic process that makes this energy conversion possible.
A Brief History of Solar Panels
The first solar panel was invented almost two centuries ago, but it wasn’t until the 1950s and 1960s that solar technology began to advance significantly. Back then, solar panels were only 10% efficient, meaning just 10% of the sunlight absorbed was converted into electricity.
Today, modern solar panels have an efficiency rate of around 20%. While this may not sound like a lot, it’s important to remember that sunlight is free and abundant. With advancements in technology, solar panels are becoming even more efficient and affordable.
Benefits of Solar Power in Malaysia
- Lower Electricity Bills
By generating your own electricity, you can significantly reduce your reliance on the grid. This means lower monthly electricity bills, with potential savings of up to 80%. - Earn Money Through Net Metering
Malaysia’s Net Energy Metering (NEM) scheme allows you to sell excess solar energy back to Tenaga Nasional Berhad (TNB) or Sabah Electricity Sdn Bhd (SESB). This means you can offset your electricity costs or even earn money by contributing to the grid. - Environmentally Friendly
Solar power is a clean, renewable energy source that reduces your carbon footprint and helps combat climate change. - Increased Property Value
Homes equipped with solar panels often have higher property values, making them more attractive to buyers.
Recent Changes to Solar Power in Malaysia
Malaysia has introduced several initiatives to make solar power more accessible and financially rewarding:
- Net Metering (NEM)
The NEM scheme has been updated to operate on a “one-to-one” basis. This means that for every unit of solar energy you sell back to the grid, you earn the same price as one unit of grid electricity. This significantly boosts your potential earnings and makes solar power a more attractive investment. The scheme was also extended to Sabah in 2019, allowing more Malaysians to benefit from solar energy. - Peer-to-Peer (P2P) Energy Trading
In 2020, Malaysia began trialling P2P energy trading, which allows homeowners to sell excess solar energy directly to their neighbours through the TNB grid. This not only promotes a greener community but also creates new opportunities for earning passive income.
How Much Do Solar Panels Cost in Malaysia?
The cost of solar panels in Malaysia varies depending on several factors, including:
- The size of the installation (typically ranging from 4kW to 12kW for residential properties).
- The quality and type of solar panels.
- The provider and installation company you choose.
On average, a basic 3kW solar system can cost between RM16,000 to RM23,000. With the latest changes to the NEM scheme, homeowners can potentially recoup their investment in as little as five years.
For those who can’t afford the upfront costs, there are leasing options available. Some providers allow you to install solar panels with zero upfront costs, paying for the system over time.
Is Solar Power Right for You?
If you’re one of the 3.2 million residential homes in Malaysia with enough roof space, solar power could be a smart investment. Not only will you save on electricity bills, but you’ll also contribute to a greener future.
Before making the switch, consider the following:
- Roof Suitability: Ensure your roof is sturdy, leak-proof, and has enough space (approximately 6.27 sq ft per 1kW of electricity generation).
- Financing Options: Explore green financing programmes to ease the upfront costs.
- Provider Reputation: Choose a SEDA-accredited provider to ensure quality and eligibility for government schemes.
Conclusion
Solar power is a clean, renewable, and cost-effective energy solution for Malaysia. With initiatives like Net Metering and P2P energy trading, homeowners and businesses can not only save money but also earn from excess energy.
By investing in solar panels, you’re not just reducing your electricity bills—you’re also playing a part in Malaysia’s transition to a sustainable energy future.
