See How This JB Homeowner Slashed It to RM30 with Solar!")
Running air conditioners daily and seeing your TNB bill cross RM500 every month? Recently, a terrace homeowner in Johor Bahru (JB) installed a solar panel system and successfully slashed their massive electricity bill down to the absolute minimum connection fee—just RM30 a month!
This isn't magic; it's the result of the Malaysian government's NEM 3.0 (Net Energy Metering) initiative. By installing solar panels on your roof, you not only generate your own power but also "sell" the excess back to TNB. If your electricity costs are out of control, 2026 is the perfect time to make the switch.
To wipe out up to 90% of your bill, your system size (kWp) must be calculated precisely. More importantly, only SEDA-certified installers are legally allowed to connect your system to the TNB grid. At Solar100, we strictly vet solar companies operating in Johor to ensure you get:
Leave the heavy lifting to the professionals. All you need to do is watch your bill drop:
Yes! If your roof has enough space to fit a system that matches your monthly consumption, your usage can be fully offset. You'll only need to pay the minimum TNB connection fee (which is typically around RM3 to RM10 for most homes).
Not at all. Your home remains connected to the TNB grid. Excess energy generated during the sunny day is "sold" to TNB as credits. At night, you simply draw power from TNB, and those credits automatically offset the cost.
Depending on your local council's specific regulations (e.g., MBJB, MBIP) and your house type, permits might be required. Don't worry—the SEDA-certified installers recommended by Solar100 will manage all relevant paperwork for you.
