Calc
A quick ballpark for friends thinking about solar in Northern Thailand. Calibrated against this dashboard's real Hang Dong system data.
About how much is your electric bill each month?
฿4,400
That's pretty average for a Chiang Mai home.
How many panels do you think would fit on your roof?
12panels
Rough rule of thumb: about 1.5 m² per panel. A typical 4-bedroom home fits 10-14.
When are you home using the most power?
About even
If you run air-con only at night, slide right. Work-from-home with daytime AC, slide left.
Would you also add a battery?
A battery stores extra sun-power to use at night. Without one, daytime extras are lost (Thailand doesn't pay you for sending power back to the grid).

With battery vs without which makes more sense for you
Panels only
฿19,000/yr saved
Panels + battery
฿36,000/yr saved
A battery is a good fit. Because you use power evenly across day and night, adding a battery saves you about ฿17,000/yr more than panels alone.

How we know: This dashboard's home in Hang Dong has 8 months of real solar data — 6.6 kW of panels & a 13.3 kWh battery, with an actual installed cost of ~฿534,000. Cost estimates assume a similar full-service install; budget DIY installs may run 30-40% lower. Savings include real-world losses (cloudy days, conversion, battery wear) that bring offset in line with what Marcus actually achieves. This is a rough guide, not a quote.
