Strong sun, rising bills — the numbers work here
Phuket combines near-equatorial sunshine with some of the highest household electricity use in Thailand — air-conditioning, pool pumps and villas that run all day.
Pool villas benefit most: pumps, aircon and daytime staff loads line up exactly with when the panels produce. Battery storage (hybrid systems) can extend savings into the evening and keep essentials running during outages.
Free site survey — written savings estimate in THB
Every roof, load profile and equipment selection is different, so we don't do one-size-fits-all price lists. We start with a free survey and give you real numbers for your property.
What drives the cost: system size (kW), whether you add battery storage for a hybrid system, roof type and cable runs, and the equipment tier you choose (we install Tier-1 brands such as LONGi, Huawei and Deye).
Equipment chosen for salt air and monsoon rain
Beachfront and hillside-sea locations are hard on hardware. We specify corrosion-resistant mounting, coastal-rated equipment from Tier-1 brands, and offer ongoing maintenance and panel cleaning so your system keeps performing through Phuket's wet season — panels still generate from diffuse light on overcast days, just at reduced output.
Real installations by our own crew
No stock photos — these are our technicians on real roofs in Phuket and Phang Nga.
Behind every job is a full in-house team of engineers, technicians and installers with more than 20 years of experience in power systems, working to international quality standards ISO 9001:2015 (quality management) and ISO 50001:2018 (energy management) — backed by a long-standing network of local partners across Phuket, from contractors to hotels and local businesses.

Common questions from villa and business owners
How much does solar installation cost in Phuket?
Every roof, load profile and equipment selection is different, so we don't publish one-size-fits-all prices. Instead, we start with a free on-site survey and then provide a written, itemised quote in THB together with a savings and payback estimate — typical payback in Phuket is around 3–5 years.
Can foreigners install solar on a villa in Phuket?
Yes. Whether you own the villa or manage it through a company or lease, a rooftop solar system can be installed with the owner's consent. We handle the design, installation and all PEA (Provincial Electricity Authority) paperwork, and can coordinate with your villa manager.
Do I need permission from PEA to install solar?
Yes. Grid-connected systems in Phuket must be registered and synchronised with the Provincial Electricity Authority (PEA). We prepare and submit all documents as part of every installation, so the system is fully legal and safe.
How long is the payback period for solar in Phuket?
Typically around 3–5 years, depending on how much electricity you use during daylight hours, the system size and whether you add battery storage. With grid electricity around 4.3 THB per unit and strong year-round sun, Phuket is one of the better locations in Thailand for solar.
Does salt air near the beach damage solar systems?
Coastal humidity and salt spray are real considerations in Phuket. We select corrosion-resistant mounting hardware and equipment rated for coastal conditions, and offer maintenance and panel-cleaning services to keep the system performing for decades.
