Solar installation in Phuket
for villas, homes and businesses
We design, install and maintain rooftop solar systems across Phuket, Phang Nga and Krabi — engineering-led, with every PEA permit handled for you. Cut your daytime electricity bill and let the Andaman sun pay you back.
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.
Typical system prices in Phuket
Approximate on-grid pricing, excluding batteries and VAT. Every roof is different — final quotes always follow a free on-site survey.
| System size | Suits | Output ≈ units/month | Guide price (THB) |
|---|---|---|---|
| 3 kW | Small home / apartment-style loads | ~450 | 150,000–220,000 |
| 5 kW | Family home, several aircon units | ~750 | 220,000–320,000 |
| 10 kW | Pool villa, high daytime use | ~1,500 | 350,000–500,000 |
| 15 kW + | Large villa, hotel, restaurant, business | ~2,250 + | Custom design — cost per kW decreases with size |
Battery storage for hybrid systems is quoted separately by capacity. Prices are indicative and depend on equipment selection, roof type and cabling.
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.

Monitoring guidance, maintenance visits and panel cleaning. Panel performance warranties from major brands typically run ~25 years; inverters ~5–10 years depending on brand.
Common questions from villa and business owners
How much does solar installation cost in Phuket?
As a rough guide (excluding batteries and VAT): a 3 kW system is around 150,000–220,000 THB, 5 kW around 220,000–320,000 THB, and 10 kW around 350,000–500,000 THB. Every roof is different, so final pricing always follows a free on-site survey.
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 4–7 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.
