The inverter of your solar PV system is a key component to ensure you system is running well.  An inverter’s primary purpose is to convert the electricity produced by solar panels from direct current (“DC) to alternating current (“AC”) so that it can be utilized for powering your home.  

In general, there are two main types of inverters, Microinverters and String inverters.

Microinverter vs String Inverter: What’s the difference?

Microinverters and string inverters differ primarily in their location and timing of converting DC energy to AC energy.

1. Safety

A string inverter is mounted usually on the ground floor and converts the electrical currents from all solar panels at a central location.  Microinverters are smaller and mounted on the back of the solar panels where they convert the direct current (DC) to alternating current (AC) at the source, making microinverters a much safer option.  

With microinverters, there is no build-up of DC voltage as the conversion from DC to AC occurs at the source.  Instead of converting DC to AC at one single source (string inverter), it is well spread out between the numerous micro inverters, operating at a lower voltage compared to string inverters.

2. Greater performance

As each panel is connected in parallel to a microinverter, the performance of each panel is independent, providing better performance in situations where some panels might be partially shaded or experience varying conditions. 

Referring to the house above, with panels facing every angle, there will be instances where the sun is shinning on certain panels whereas some others may not receive the same sunlight.  With microinverters, as each panel is independent, the generation will be optimized.

This independence in performance is a key advantage of microinverters, offering more flexibility and efficiency in real-world scenarios compared to traditional string inverters.

3. Better performance monitoring and troubleshooting

Our experienced maintenance team can monitor and identify any fault using the individual panel-level monitoring.  This speeds up troubleshooting instead of having to check every panel to identify the fault.

This further allows us to have panel-level shutdown capabilities when needed, allowing us to isolate and shut down the output of a specific solar panel if needed.  Further enhancing safety in case of a malfunction or maintenance requirement

4. Modular design

Microinverters make it easier to scale and expand solar power systems.  Additional panels with microinverters can be seamlessly integrated into an existing system without the need for major redesign or modification.  Most of the time, there will be no change to the internal existing cabling works.

This is a great advantage for our customers whose electricity usage pattern may change overtime with the addition of an EV cars, removal of electricity subsidy, renovation etc.  Having the flexibility to add more panels in the future will help to hedge against the ever-increasing cost of electricity.

Lower Energy Bills 

One of the most significant benefits of a solar PV system is that it can significantly lower your energy bills. Your solar PV system can generate electricity by harnessing energy from the sun, which means that you can reduce your reliance on grid power. This translates to lower energy bills and more money in your pocket. 

Increase the Value of Your Home 

Your solar PV system can increase the value of your home. As more people become environmentally conscious, the demand for homes with renewable energy systems increases. Therefore, a solar PV system can make your home more attractive to potential buyers and increase its resale value. 

Reduce Carbon Footprint 

Another compelling reason to install a solar PV system is to reduce your carbon footprint. Solar energy is a clean and renewable source of energy that does not produce harmful emissions. By installing a solar panel system, you can reduce your carbon footprint and help to preserve the environment. 

Minimal Maintenance 

Solar PV systems require minimal maintenance. Once installed, they do not need any special attention, and you do not need to worry about cleaning or replacing them frequently. Solar panels are durable and can last for up to 25 years or more with little maintenance. 

Government Incentives 

The Malaysian government offers incentives to homeowners (NEM) who install solar PV systems on their home’s rooftop. 

Long-Term Savings 

Finally, a solar PV system can provide you with long-term savings. Although the initial cost of installation may be high, the savings over the lifespan of the system can be substantial. With rising energy costs, a solar PV system can help you save money in the long run. 

In conclusion, a solar PV system is indeed a wise investment for homeowners who want to save money, reduce their carbon footprint, and increase their home’s value. With minimal maintenance and long-term savings, installing a solar PV system is a smart choice for homeowners who want to take control of their energy consumption and become more self-sufficient.

In order to encourage the use of renewable energy in Malaysia, the Net Energy Metering Scheme (NEM) was first introduced by the government with a quota of 500 MW allocated up to the year 2020.

This year, the government released NEM 3.0 to continue this initiative with an increased capacity of 800MW, to give users enough quota to use. NEM 3.0 is divided to three categories as per follows:

What is Net Energy Metering (NEM) in Malaysia and What are Its Benefits?

You might be curious about what exactly Net Energy Metering is, and how you can benefit from using it. Let us share with you how! 

The term “Net Energy Metering” (NEM) is a scheme in which the energy generated by a solar photovoltaic (PV) system installed at your premise, will be used first, and then any excess energy generated will be exported back to the grid as credits, provided by Tenaga Nasional Berhad (TNB) and then used to offset your next electricity bill.

Using net metering in Malaysia will benefit you because it is an alternative for generating electricity from your own solar PV system to offset and reduce your monthly electricity bill.

Solar PV solution providers like us, ensure that your solar PV system is compatible with the energy grid, and  it does not endanger you or anyone else while you maximise your return of investment and savings.
