All our solar services

From design and installation, through the permit paperwork with the electricity authority, to panel cleaning and aftercare — every job is done by our own installation team.

Installation

Choose by the kind of property

Each group uses electricity at different times and in different ways, and that — not just the size of the roof — decides what kind of system makes sense.

Solar for homes and villas

Designed around your actual electricity bill and how your household uses power.

Solar for factories and businesses

Wide-span roofs get a structural check first, and shutdown windows are planned so your production line keeps running.

Solar for hotels and resorts

Installed in phases so guests are not disturbed, with salt-resistant equipment chosen for beachfront properties.

Hybrid systems with battery storage

For areas with frequent brownouts and power cuts, or businesses that need a steady supply through the night.

Agriculture

Farm systems by crop, because each uses power differently

Rubber farms use power in post-tapping processing, oil palm at the collection yards and sorting sheds, and durian orchards for irrigation in the dry season. Each of the three is designed a different way.

Solar for farms in Southern ThailandAn overview of every farm use, from field pumps to smokehouses, palm ramps and ponds.Solar water pumpsPump groundwater and surface water where the grid doesn't reach — no new electricity meter needed.Rubber plantations, smokehouses and buying yardsThe real load is in post-tapping processing, not the plantation itself, and the equipment has to withstand acid fumes.Oil palm plantations, collection yards and millsSemi-industrial work where getting the permit from PEA (the Provincial Electricity Authority) takes longer than the installation.Durian orchards and fruit farmsIrrigation on sloping land sized from the real pumping height, and packing houses that only use power in season.

Property & business types

Choose by type of property

Each kind of property uses power at different times — from villas, restaurants and offices to cold storage and shrimp ponds.

Solar for small businessesAn overview for shops, offices, guesthouses and small businesses that use power through the day.Pool villas & holiday homesAir-con and pool pumps run through the day, and backup power matters for rental villas.Shophouses, shops, restaurants & cafésOpening hours decide how much of the solar output the business actually uses.Offices, clinics & companiesWorking hours line up with daylight, and full tax invoices are issued.Dormitories, apartments & homestaysDesigned around common-area and owner-paid loads.Cold storage, ice plants & fish piersLoads run all day, so almost every unit generated gets used.Warehouses, logistics, garages & piersWide roofs and daytime loads from transport and repair work.Petrol stations & forecourt storesDaytime store loads, with electrical gear kept outside the hazardous areas around the pumps.Shrimp ponds, fish ponds & aeratorsSolar only helps while the sun is up, so the system is planned around when the machines really run.Fruit orchards & packing housesPacking houses use heavy power only in season, so both seasons are planned for.Rice fields & rice millsSized from the real running hours of the mill and the field pumps.

Roof type

Every roof type is mounted a different way

Roof type moves the price and the installation time more than anything else, and it decides whether anything needs repairing before we install.

Metal sheet roofsSeam clips on standing-seam roofs, or screws into the purlins with rubber seals. The challenges are screw holes and purlin spacing.Tile roofsHooks are fixed to the rafters, never to the tiles. The challenges are cracked tiles and finding matching replacements.Flat concrete roofsFree choice of direction and tilt, but the existing waterproofing, row spacing and higher wind uplift all need checking.

Paperwork and aftercare

The work that isn't a new installation

These two decide whether a system is actually allowed to run, and how long it keeps performing.

PEA permit paperwork

We submit engineer-certified drawings, arrange the inspection and handle the meter change — every step of it.

Panel cleaning and aftercare

Coastal and dusty sites need more frequent cleaning, because grime blocks sunlight and bakes on hard.

FAQ

Questions about scope and costs

What size of project does 19Energy take on?

Anything from a 5 kW home system up to commercial buildings and factories. On the farm side, we handle everything from a small stand-alone solar pump set in the field up to rooftop systems on collection yards and sorting sheds. What we won't promise is to bring a large factory's electricity bill to zero — the roof simply can't generate enough power for a full production line. That is a physical limit.

Do I have to pay anything before I get a quote?

A first estimate from your electricity bill costs nothing — send us a photo of the bill and we will run the numbers for you. An on-site survey carries a fee of THB 1,200–1,500, refunded in full against your quote when you go ahead with the installation. The fee covers fuel, a technician's full day away from installation work, and the time to prepare your report, so the survey is charged, not free.

Do you handle the paperwork with the electricity authority?

Yes, every step: electrical drawings certified by a licensed engineer, the application to PEA (the Provincial Electricity Authority), arranging the on-site inspection and the meter change. This process decides when your system actually starts running more than the installation itself does, so we give you the expected timeframe when we quote.

Do you look after the system after installation?

Installation work carries a 2-year warranty, and we offer ongoing panel cleaning and system checks. Every system we install comes with an app that shows your generation history, so you can spot unusual numbers straight away and we can make a first diagnosis remotely before sending a technician.

Not sure which group your project falls into?

Send us your electricity bill and a few photos of the site. We will tell you what kind of system suits it, and whether it makes financial sense yet.

Our team replies in English — on LINE, by email or by phone. Sending a photo of your electricity bill and your location on LINE is the quickest way to get an estimate.
