Monthly bill: ฿16,000 → ฿3,100. That is an 80% reduction — saving ฿12,900 every single month, or nearly ฿155,000 a year.
Meet Khun A — Our 9th Installation
Khun A works from home full-time. She keeps the air conditioning running throughout the day — not just for herself, but for her dogs and cats. In Thailand's increasingly hot climate, this is not a luxury; it is a necessity. The result was a monthly electricity bill that averaged a painful ฿16,000.
What Our Engineers Did
- Conducted a full roof and sun-angle analysis to determine the optimal panel layout for her property
- Mapped her actual usage pattern — high daytime load from AC running continuously — and sized the system to match peak consumption hours
- Designed a custom solar system tailored to her specific roof, budget, and daily consumption — not a one-size-fits-all package
The Results
| Before Solar | After Solar | Monthly Saving | Annual Saving |
|---|---|---|---|
| ฿16,000/เดือน | ฿3,100/เดือน | ฿12,900 | ~฿155,000 |
Why Such a Big Saving?
- Work-from-home lifestyle is perfect for solar — appliances run during daylight hours when panels are producing at full output
- Continuous AC load is one of the highest-consuming uses — and it runs exactly when solar production peaks (9 AM–4 PM)
- Thailand's tiered electricity rate means the first units saved cut the most expensive billing tier — maximising the baht value of each solar unit

Frequently Asked Questions
I also run AC all day — can I expect similar savings?
Continuous daytime AC load is actually the ideal profile for solar. Results vary by system size, roof direction, and usage pattern, but work-from-home households typically see the strongest payback of any residential category. A free bill analysis will give you a personalised estimate.
How long did installation take for Khun A's home?
A typical residential installation takes 2–3 working days from start to finish, including mounting, wiring, inverter installation, and grid connection. We schedule at a time that causes minimal disruption to your daily routine.
What if my electricity bill is lower than ฿16,000 — is solar still worth it?
Yes — solar delivers a positive return even at bills of 3,000–5,000 THB/month. The payback period is longer at lower bills, but the investment still earns a better return than a savings account. Use our ROI calculator or request a free bill analysis for your specific situation.
