Everything you need to understand residential solar in Malaysia — Solar ATAP, SuRIA incentives, ROI, and real savings explained clearly.
From sunlight to savings in six clean steps.
Absorbs sunlight with photovoltaic cells, generating direct current (DC) electricity.
Converts direct current (DC) to usable alternating current (AC) for your home.
Distributes the converted AC electricity to power your home's appliances and circuits.
Any surplus electricity is exported to TNB's grid, or stored in a battery if installed.
A bidirectional meter records how much energy is imported from and exported to TNB.
Optional. Unused energy captured during the day is stored for use at night or during outages.
Generate your own electricity from sunlight, reduce your monthly TNB bill, and receive credits for excess energy exported to the grid.
Your rooftop solar panels convert sunlight into electricity during the day.
The electricity generated is used immediately by appliances such as air conditioners, refrigerators, lights, TVs and other household devices.
Every unit of solar energy you use directly is electricity you no longer need to buy from TNB.
If your solar system generates more electricity than your home is using, the surplus energy is automatically exported to the grid.
Under Solar ATAP, exported energy earns bill credits that offset your electricity consumption for that month. Note: credits reset monthly and do not carry over — making correct system sizing important.
At night or during low solar production periods, your home automatically draws electricity from TNB as normal.
Reduce your dependence on grid electricity by generating your own clean energy.
Surplus solar generation can be credited through the Solar ATAP mechanism.
Generate more of your own electricity and reduce exposure to future energy price fluctuations.
Reduce your household carbon footprint while contributing to Malaysia's renewable energy goals.
Sustainable Rebate & Incentive Assistance (SuRIA) Home is a government programme to help residential customers reduce electricity costs through rooftop solar — with a direct cash rebate of up to RM 3,000.
Up to a maximum of RM 3,000 per household. Paid directly into your bank account — actual cash, not a tax relief.
System must be commissioned under Solar ATAP and connected to TNB by this date. Programme also ends early if the 250 MW national quota is fully taken up — whichever comes first.
Supports an estimated 45,000–50,000 homes and a cumulative 250 MW of installed residential solar. Programme ends when the quota or the deadline is reached — whichever comes first.
Eligible customers will be notified via their TNB-registered email in phases from 1 June 2026 to submit bank details.
* Each customer is entitled to only ONE rebate.
