Why sky2home
Solar power without owning the system
No six-figure upfront cost and no maintenance worries. You pay a fixed monthly fee that is lower than the value of the electricity the system produces.
฿0 installation
We pay for the panels, inverters and installation — worth ฿44,000–220,000 — on your behalf.
Fixed monthly fee
From ฿390/month, charged automatically to your card or bank account — just like your internet or phone bill.
Fully looked after
Asset insurance, panel and inverter warranties, scheduled cleaning, and production tracked through our monitoring system.
Explained in a minute
Like signing up for home internet,
but you get “electricity”
With home internet you don't buy the fibre or the router — the provider installs them and you pay a monthly plan. sky2home works the same way, except you get electricity from the sun instead of internet.

Which package fits your home, and how much could you save?
Answer 3 questions — results update instantly.
Not sure? Use the estimate from step 1 — we measure properly during the survey (or screen your roof by satellite).
“With sky2home” = remaining grid bill + sky2home fee
Assumptions: average tariff ฿4.5/kWh · grid emissions 0.5 kg CO₂/kWh · surplus daytime energy is not counted as savings · actual results depend on the site survey.
System preview
See the system on your roof in 3D
Pick a package, try different roof layouts, check the actual equipment, and see how power flows through your home at different times of day.
Which way does your home face, and how much power can it make?
Drag the model to rotate it • Move the time slider to watch the sun travel from east to west
Thailand is north of the equator, so the sun travels slightly to the south for most of the year — panels facing south produce the most power.
House facing South • Click a bar to see the sun at that time
* Clear-day estimate based on an average of 120 kWh per kWp per month with the roof facing the best direction (720 W per panel). Actual output depends on season, weather and shading.
This preview is a guide. Our engineer confirms the actual panel layout and equipment during the site survey.

FAQ
What to know before you sign up
What do I pay besides the monthly fee?
There is no installation or equipment cost. You pay only your package's monthly fee (excl. VAT) plus whatever grid electricity you still use.
What happens after the 5-year contract?
You have 3 options: renew the service, buy the system, or have us remove it. [Terms and prices to be confirmed]
Who is responsible if a panel fails or output drops?
We own the system and look after it. It is covered by asset insurance and the panel and inverter warranties, and we clean the panels on a schedule.
What equipment do you install?
Trina Solar Vertex N 720W panels (N-type i-TOPCon, bifacial dual glass, 30-year power warranty) with ATMOCE MI-1250 microinverters (15-year warranty). You can see each panel's output in the app.
Can I sign up if my home is mortgaged?
Yes, but we need to review the lien first. In some cases a security deposit is required, which is refunded when the contract ends.
Can I buy the system outright instead?
Yes. A 5 kWp system is ฿175,000 and 10 kWp is ฿298,500 (excl. VAT), including ATMOCE MS-7K-U battery storage, a 2-year workmanship warranty and free yearly panel cleaning for 2 years.
What if I move during the contract?
[Policy to be confirmed: transfer to the new owner / relocate the system / early-termination fee]
