About 19Energy
SIPKAO ENERGY CO., LTD. — a rooftop solar installation team from Nakhon Si Thammarat, Southern Thailand.
We are a solar installation company registered in Nakhon Si Thammarat. We install for homes, factories, hotels and all kinds of businesses across 13 provinces of Southern Thailand.
What matters most to us is that you can make your decision based on numbers you can check. Our payback figures come with the assumptions used to calculate them, and the warranty is listed part by part according to the manufacturers’ documents — so you can compare every line against any other quote.
We lay out all of our reasoning and let you decide whether the investment is worth it.
How we work
The commitments we keep with every customer
Designed from your real bill
The best-value system is the one that matches your daytime electricity use. That's why we look at your bill before we quote.
Every number comes with its assumptions
Savings and payback figures come with the assumptions behind them: the price per kWh, the amount of sunshine, and the share of the power you use yourself.
A realistic assessment
We size the system from your real daytime use. Homes that use little power during the day are usually best suited to a smaller system.
Named brands and models
Our panels are JA Solar, LONGi or Jinko Solar and our inverters are HUAWEI, Solis or Deye, chosen to suit the job and your budget. The exact brand and model are written into your quote before you sign anything. You can check the specs yourself.
Warranty broken down as documented
Panels, inverters and installation work carry different warranty periods. We list each part separately and hand over the original documents with the installation.
No shortcuts on permits
We don't take jobs that ask us to skip filing with the electricity authority, because all of that risk ends up with the property owner later.
A local team
A team that stays in the area for the life of your system
A solar system stays with your property for decades. Alongside the price, another question matters just as much: “five years from now, if the inverter shows a red light, who will come and fix it?”
Our team is based in the South itself, and 19Energy's own technicians handle every after-sales visit.
And before you commit, we confirm the survey date and any travel charge for your area.

FAQ
What people ask before choosing an installer
Who is 19Energy, and is the company properly registered?
We are registered as SIPKAO ENERGY CO., LTD. (บริษัท สิบเก้าเอ็นเนอร์ยี่ จำกัด), tax ID 0805566004191, founded on December 19, 2023. Our registered office is in Nakhon Si Thammarat Province, and we are VAT-registered, so we issue full tax invoices and support 3% withholding tax. The company details can be checked in the Department of Business Development database.
Who carries out the installation work?
19Energy's own technicians handle every job. That matters more after the installation than during it, because the people who come back to look after your system are the same people who installed it and know how your site was wired. We give a 2-year warranty on installation and mounting work, plus 2 years of free aftercare.
Can I see your previous work before deciding?
Yes. Our portfolio has more than 400 photos from real job sites, and our case studies show the site photos and equipment for each job — from 5 kW home systems up to a 760 kW project. If you would like to see an installation in person, get in touch and we will arrange a visit if the owner agrees.
How is the installation price worked out?
The real cost of a job varies a lot with roof type, structural condition and cable runs, so each job is priced individually. We survey the site first and quote a price that holds. The survey costs THB 1,200–1,500 and is refunded in full against your quote when you go ahead with the installation. Our pricing page explains what makes the price go up or down.
Which provinces do you 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 and Narathiwat. The same terms apply in every province: site surveys are by appointment, and any travel charge is confirmed before booking. We do not serve Ranong.
