Calc

A quick ballpark for friends thinking about solar in Northern Thailand. Calibrated against this dashboard's real Hang Dong system data.

You'd save

฿36,000

per year on your electric bill

how much of your bill solar covers

Pays for itself

after that, everything saved is profit

Power you'd make

10,200kWh/yr

~28 kWh on an average day

About how much is your electric bill each month?

฿4,400

฿500฿15,000

That's pretty average for a Chiang Mai home.

How many panels do you think would fit on your roof?

12panels

4 (small roof)30 (big roof)

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

Mostly daytimeMostly nighttime

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).

Your monthly bill before solar vs after

Before After

Your savings over 20 years 2.5% rate inflation, 0.5% panel degradation

Cumulative savings System cost line

With battery vs without which makes more sense for you

Panels only

฿19,000/yr saved

Cost ฿231,000 Payback 12.0 yrs

Panels + battery

฿36,000/yr saved

Cost ฿451,000 Payback 12.5 yrs

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.
