Solar Panel Installation in Surat Thani & Koh Samui

Yes. We provide surveys, installation and after-sales care in Surat Thani Province. Site surveys are by appointment, and any travel charge is confirmed before booking.

You can check your generation yourself in the inverter's app, so you can report a problem as soon as the figures look wrong, and we can make a first diagnosis remotely. When a site visit is needed, we book it by appointment in Surat Thani & Koh Samui, covering Mueang Surat Thani, Koh Samui and Tha Chang and the other districts in the province, and always confirm the date in advance.

We don't add a surcharge by province. Any travel charge is confirmed before booking. What really changes the price is the site conditions, not the location. In Surat Thani & Koh Samui, the conditions that move the price most are the differences between districts. It has both island work and mainland work within one province, two kinds of job that are planned and costed for transport in completely different ways. Our quote therefore comes from a real site survey, which costs THB 1,200–1,500 and is refunded in full against your quote when you go ahead with the installation.

Yes. The province is on the Gulf of Thailand side. The heaviest rain comes at the end of the year, and the islands and the mainland do not get the same number of clear days because clouds form differently over each. 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. The payback figures we give are based on real conditions in the South.

All 19 districts of Surat Thani Province. Send us your district name on LINE and we will arrange a survey date and confirm any travel charge before the visit.

Yes. The first is a 15 kW three-phase hybrid system on Koh Samui, using a Solis 15 kW inverter and an LVTopsun 314Ah battery, for a home that wanted solar power together with backup. The second is a 35 kW on-grid system on a building in Tha Chang district, for a business that uses most of its power in the daytime.

Every piece of equipment crosses by boat, and at many bays on Koh Pha Ngan and Koh Tao it then has to be carried up steep slopes from the pier. An on-site fix that needs extra parts therefore costs weeks rather than days. We survey in more detail than usual before ordering, and lock the shipping and installation schedules together from the start. Being surrounded by sea also makes salt-resistant equipment standard, not an optional extra.

Yes, as long as it is sized correctly. A pump lifting water uphill needs much more power than one pumping on flat ground, even at the same flow rate. We calculate from the actual lift height plus the pipe length, not just from the size of the existing pump. Sizing from the lift height ensures the water reaches the top of the slope.

Air-conditioning and fridge loads at retail stores in Wiang Sa peak in the late afternoon, about two hours after the panels' peak output. We therefore look at hourly usage, not just the monthly total. In cases like this, a small battery that shifts power into the afternoon often pays off better than adding more panels.

More than it looks. Coconut fronds cast narrow moving strips of shade across the roof all day. This kind of strip shading costs series-connected panels more output than the shaded area alone would suggest, so string layout and module-level power electronics matter more here than on an open site.
