Solar Installation in Southern Thailand
We provide surveys, installation and after-sales care across 13 provinces in Southern Thailand — from Phuket, Krabi and Khao Lak on the Andaman coast to Koh Samui and Surat Thani on the Gulf.
Why we spell out our service terms by area
A solar system isn't finished when the installation is. It still needs its panels cleaned on schedule, an annual check-up, and the occasional visit from a technician when the generation figures look wrong. So before you install, you should know how your installer looks after your area.
That is why the same terms apply in every province we serve: site surveys are by appointment, and any travel charge is confirmed before booking. That way you know the full cost before you decide.

FAQ
About our service areas
How many provinces does 19Energy cover?
13 provinces in Southern Thailand: Nakhon Si Thammarat, Phatthalung, Songkhla, Trang, Surat Thani & Koh Samui, Krabi, Phang Nga & Khao Lak, Chumphon, Satun, Phuket, Pattani, Yala, Narathiwat. The same terms apply in every province: site surveys are by appointment, and any travel charge is confirmed before booking.
My province isn't on the list. Can I still contact you?
Yes. Tell us your district and we will confirm the survey date and how after-sales visits work in your area.
Does installation cost more in some provinces?
The same terms apply everywhere: any travel charge is confirmed before booking. The installation price itself is not marked up by province; it varies with roof type, structural condition and cable run length. A site survey costs THB 1,200–1,500, refunded in full against your quote when you go ahead with the installation.
Is there enough sunshine in Southern Thailand for solar?
Yes. We calculate using a Southern Thailand solar yield of 1,350 kWh per kWp per year, which already includes the rainy season and is lower than for other regions of the country. Our figures are based on real local conditions.
The site survey fee of THB 1,200–1,500 applies within 100 km and is refunded in full against your quote when you go ahead with the installation. A first estimate from your electricity bill is free — just send a photo of the bill on LINE.
