A long weekend in KL & Selangor means one thing: Family is home all day. Usually, this equals a massive spike in your TNB bill as 3-4 air conditioners run non-stop from morning till midnight.
But for Solar ATAP owners, a sunny holiday is actually a money-saving opportunity. Instead of fearing the electricity meter, use this “Secret Weapon” strategy to keep your home cool for nearly zero cost.
The “Solar Pre-Cooling” Strategy ❄️
Most people turn on the AC only when they feel hot (usually in the evening). This is wrong. Your walls and furniture absorb heat all day, making your AC work twice as hard at night (pulling expensive grid electricity).
🚀 The 11 AM – 3 PM Hack
Step 1: Blast your ACs at 11:00 AM when your solar production hits its peak.
Step 2: Set temperature to 22°C-24°C.
Step 3: Turn on ceiling fans to circulate the cool air.
Why? You are using FREE solar energy to cool down the thermal mass (walls/floors) of your house.
By 4:00 PM, your house is an “icebox.” You can then switch off the AC or set it to “Fan Mode” for the evening. Your house stays cool well into the night without draining grid power!
Don’t Fly Blind: Use the HOMI App 📱
How do you know if you’re using too much AC? Our smart monitoring app gives you X-Ray vision into your energy usage.
- Real-Time Graph: See the green curve (Solar Generation) vs. the red curve (Consumption).
- “Free Zone” Alert: As long as the Red line stays below the Green line, your electricity is 100% free.
- Leak Detection: Spot if a specific appliance (like an old fridge) is secretly draining power while you’re out for holiday lunch.

What if it rains on the holiday?
If it rains, solar production drops. Check your HOMI App! If the Green curve (solar) drops below the Red curve (usage), turn off 1-2 ACs or raise the temperature to 26°C to avoid pulling too much from the grid.
Does turning AC on/off waste more power?
For modern Inverter ACs, it’s better to keep them running at a steady low power (maintained temperature) using solar energy than to shut them off and restart them at night using grid power to fight the accumulated heat.
Can I automate this “Pre-Cooling”?
Yes! Use smart home plugs or WiFi-enabled AC controllers (like Sensibo) to schedule your ACs to turn on automatically at 11 AM. You don’t even need to be home.
