Net Energy Metering (NEM) is a system where the energy generated by a solar power system is used first by the consumer. Any excess energy produced is then sent back to the grid, offsetting the consumer’s energy use on a one-to-one basis over a period of 10 years.

Due to the high demand for NEM 2.0, NEM 3.0 was introduced in December 2020 with a quota allocation of 500 MW. This new phase aims to further promote the adoption of renewable energy in Malaysia.

A solar power system primarily consists of solar panels and inverters. Typically, solar panels have a lifespan of 25 years, backed by a manufacturer’s performance warranty, while inverters generally last about 10 years. Most solar panels come with a 12-year product warranty, and most inverters come with a 5-year product warranty.

Replacing inverters can cost between 10% and 20% of the total cost of the solar power system, depending on their quality. Inverters are crucial as they serve as the heart of the system, protecting and regulating it. To extend the lifespan of inverters, precautions such as ensuring good airflow to reduce operating temperature, keeping them away from water or rain splashes, and investing in higher quality inverters can be taken. Additionally, the warranty for inverters can often be extended up to 15 to 20 years, depending on the manufacturer.

For fixed-mounted solar panels, the optimal direction is to face south. However, due to various uncontrollable factors, we encourage clients to utilize any available space to maximize solar energy production.

Our experienced system designers will provide an estimated performance based on the specific characteristics of each site.

Peak Sun Hour (PSH) is a performance indicator that measures the amount of solar irradiance received at a particular site. One PSH is equivalent to 1 kWh/m² and is typically calculated based on the daily average solar energy output over a year. Essentially, the higher the number of PSH, the more energy can be harvested from sunlight.

In Malaysia, the average PSH ranges from 4 to 4.9, excluding environmental factors.

A well-designed solar power system should generate at least 3.3 PSH (Peak Sun Hours) on average throughout the year, provided there is minimal shading on the panels. For example, a 10 kWp system should produce approximately 12,045 kWh annually (calculated as 10 kWp × 3.3 PSH/day × 365 days = 12,045 kWh/year).

Keep in mind that PSH can vary by location, so it’s important to refer to the performance estimates provided by your solar power system designer.

There are two main types of solar power systems: Grid Connected Photovoltaic (GCPV) and Off-Grid Photovoltaic (OGPV). The NEM scheme is designed for solar power systems connected directly to the grid. In this setup, any excess energy generated is exported back to the grid, and additional energy needed is imported from the grid. Therefore, a battery pack is not necessary.

The Net Energy Metering (NEM) incentive, granted by the Sustainable Energy Development Authority (SEDA), is available in limited quotas. Historically, each new NEM scheme has offered fewer or less favorable incentives compared to its predecessor. Meanwhile, the cost of solar power systems has decreased over the years, maintaining a consistent return-on-investment period since NEM was first introduced.

SEDA has been active in Malaysia since 2011, with thousands of megawatts installed nationwide. The adoption of solar power systems in Malaysia has progressed beyond the innovators and early adopters phase and is now moving toward market maturity. At this stage, prices are highly competitive for early-majority adopters. Therefore, now is an excellent time for clients to install a solar power system to take advantage of the best deals available.

Yes, you can install solar panels on your car porch if it is on residential land. It is preferable to install them on a zinc roof with minimal shading.

Your inverter should be mounted on a wall that allows easy accessibility, good airflow, and protection from water splashes. Ideal locations include the car porch, balcony, attic, or an indoor area.

For NEM systems, connecting to the existing distribution box (DB), whether the main DB or sub-DB, is sufficient. Ensure the cable is thick enough to support the current. There’s no need to connect directly to the meter.

We utilize special aluminum mounting structures designed for various roof types, including tile, zinc, or concrete roofs.

To prevent roof damage and the risk of leaking, no drilling is conducted on the surface of the roof during installation.

Our solar panel systems are equipped with comprehensive protection measures against lightning. These include external and internal lightning protection systems. Each panel is grounded from the top, and surge protection devices are installed within the solar power system, adding a second layer of protection. Furthermore, the inverters are equipped with built-in circuit breakers.

When designed and installed professionally, solar power systems pose an extremely low risk of fire.

Solar panels utilize sunlight irradiation to generate energy, with wavelengths ranging between Ultraviolet (UV) and Infrared. It’s important to note that the solar power system itself does not emit any radiation.

Moreover, solar panels can contribute to reducing the temperature of the roof by blocking direct heat transfer from solar radiation, thereby offering potential benefits in terms of temperature control.
