“If TNB goes down… will my solar panels keep the lights on?”
❌ Not always — unless your system includes a battery backup or specific hybrid setup.
Let’s clarify what happens during a blackout in Malaysia and how you can stay powered up.
🔌 On-Grid Systems = No Power During Outages
Most solar systems in Malaysia are on-grid, meaning:
✅ They’re connected to TNB
✅ They send excess power back to the grid (NEM)
❌ But during a power cut, they shut down too
This is for safety reasons — to protect TNB technicians working on power lines.
🔋 Want Backup? You’ll Need a Battery or Hybrid System
If you want your solar panels to work during a blackout, you need one of these:
✅ Hybrid solar system – combines solar + TNB + battery
✅ Battery storage – stores energy for emergency use
✅ Critical load panel – powers essentials like fridge, lights, fans
These setups are becoming more common, especially in areas prone to blackouts or with frequent outages.
🏠 Is It Worth Getting a Battery?
It depends:
- If your area rarely has outages, on-grid solar might be enough
- But if you want full independence or backup for sensitive equipment, consider a hybrid setup
- Costs are higher, but peace of mind matters too
✅ Plan Ahead, Stay Powered
Don’t wait for the next blackout to think about solar backup.
