Under NEM, users will consume the electricity generated from solar energy first and then sell back any excess solar-generated energy to Tenaga Nasional Bhd (TNB) to offset the electricity that their premises have consumed from the grid at the end of the month.
Any excess of solar power generated is allowed to roll over within 12 months from the start of NEM consumer’s billing system.
No cash will be paid in the NEM scheme. Net Metering is not a scheme that allows for consumers to earn cash, however the system is a form of support for electricity consumption savings which translate to passive income, so the more solar energy used, the less is used from the TNB.
As long as you are a customer of TNB. The basis is always your electricity bill. Please ensure you are a registered customer of TNB (your name/ company as appeared in the TNB bill), only then you are eligible to participate in NEM.
The NEM is a solar PV implementation mechanism that is executed by the Ministry of Energy, Science, Technology, Environment and Climate Change (MESTECC), regulated by the EnergyCommission (EC), and implemented by the Sustainable Energy Development Authority (SEDA) Malaysia.
No problem. When you move or decide to sell your house, you have two(2) choices:
1.Transfer the agreement to the new homeowner. As it may maximize your property's resale value.
2.Transfer the system to your new home at a cost.
Yes, in order to enjoy the benefit of exporting the excess energy, the meter needs to be changed. The current/conventional meter is a one directional meter, which only reads imports. The NEM meter is a bi-directional meter which records both import and export. This will be reflected in detail on the TNB bill.

The whole process will take about 4 to 8weeks.
We provide several warranties on the system:
A) Solar Panels:
12 Years manufacturers warranty - While solar panels are very durable, it’s not unheard of for a panel to fail, most often from faulty wiring or corrosion. An equipment warranty will make sure your dead panel is replaced by the manufacturer at no cost to you.
30 Years performance warranty - A typical panel loses about 0.7% of its original production value per year. If the performance of the panels drops below 80% then the panel will be replaced with a new panel. Be wary of panel manufacturers that don’t offer long production warranties, as this may be an indicator of an inferior panel.
B) Inverter:
5 Years manufactures warranty.
C) DC Cable
25 Years manufactureres warranty.
Yes, it will be good to include solar installation work in the construction plan.
Your grid-connected solar pv systems must by law shut down if TNB power outage. The reason is that TNB technicians repairing faulty electricity wires must be able to do so safely, without any solar power travelling back into the grid during maintenance and repair. Your electricity if fed back into the line could create a danger to the TNB technicians. Therefore when there is a black out you will also be without power. Solar pv system will automatically turn on during daylight hours when the TNB power comes back.
Before you decide to go solar, it is very important to know how much electricity you use in the day. You can find your usage in kilowatt hours (kWh) on your TNB bill.
Once you know your energy usage then you can then find out what size solar PV system base on how many percent you would like to save as well as your BUDGET!.
Your reasons for installing a solar PV system will help determine how much you spend. You may wish to help the environment, or to reduce your annual TNB bills. How much you will save on your monthly TNB bills depends on how many percent do you want to save per month. Of course, bigger the system size, it is more expensive.
While there are many brands available, there are just three types of technologies involved in making a solar panel – monocrystalline, polycrystalline and amorphous thin film. Here’s a quick overview of their qualities:
Monocrystalline – have good power-to-size ratio, outstanding performance in cooler conditions and previously the most commonly used technology in the world, with over 50 years of development. Monocrystalline panels have an excellent life span / longevity and usually come with a 25 year warranty.
Polycrystalline – have good efficiency and are generally less expensive to produce than monocrystalline. They have a slightly better performance in hotter conditions and an excellent life span / longevity. They usually come with a 25year warranty.
Amorphous Thin Film – have low conversion efficiency, and expected lifespan less than crystalline panels. However they have the best efficiency in hot weather but are less effective in cooler conditions. They also require 2-3 times more panels and surface area for same output as crystalline.
All-in-all, maintaining your solar panels is pretty easy. Just be sure to get a good warranty and good insurance, and can keep your panels free of dirt and debris buildup. Do that, and your panels should continue to operate at peak efficiency, bringing you clean, renewable solar power for years to come.
Solar panels generally require very little maintenance in order to function. The only thing they need is a periodic light cleaning to make sure dirt, leaves, and other debris aren't obstructing the sun's rays. Good thing is rainfall actually clears away debris that's accumulated on them.
Generally recommended that you perform solar panel cleaning once in every 2-3years and your panels will be clean and in top condition
All solar panels will degrade over time. The typical lifespan of a solar panel is approximately 20+ years. All solar panels are affected by what is called LID or light induced degradation. Quality panels can expect a 5-10-year time-frame with maximum output of the panels dropping by 5%, whilst a lower end panel can drop by up to 10% or more.
Clouds
Cloud cover is an obvious one but worth mentioning. If clouds pass over your system, the system will have less sunlight reaching it meaning less production.
Temperature
Somewhat annoyingly, the hotter a solar panel is the less well it performs. So a solar system will perform slightly better at 11 am than at 1 pm, even though they may be getting the same amount of sunlight in each case, because at 1 pm the panels are hotter.
Shading
As much as possible, solar systems should be positioned to avoid shading. Basically, shading drastically reduces production unless you’ve got a special setup (e.g. micro-inverters). Partial shading early morning or late afternoon is acceptable if unavoidable however you don’t want shade across your panels at midday.
A solar pv system can only generate electricity when the sun is out and will not generate any energy at night. However, a solar system will still work in overcast conditions.
As a solar system does not generate energy at night a grid connected solar pv system will pull energy from TNB to ensure your home is still running as normal.
If you have added battery storage and your system has generated excess energy during the day you will be able to use this excess energy at night as opposed to relying on TNB.
You may monitor the system performance through our monitoring app. Track how much energy your panels produce on any given day, and how much they produce over time. This allows you to see exactly how various external factors affect your panels' performance and how well they're maintaining their efficiency across their life. The monitoring system will also alert you if a panel breaks or malfunctions so that you can repair or replace it.
