Solar in Phuket — frequently asked questions
Do you install solar everywhere in Phuket?
Yes. Our office is in Kathu and we install across the whole island — including Choeng Thale / Bang Tao, Thalang, Kathu, Mueang Phuket and more — as well as Phang-nga and southern Thailand.
How much does solar installation cost in Phuket?
It depends on system size, system type (on-grid or hybrid with battery) and your roof. We give you an exact quote after a free site survey. For typical price ranges, read our Phuket solar price guide.
How long does installation take?
Residential systems are typically completed within 2–5 days after the design is approved. Larger commercial systems take longer depending on size.
Do I need a battery for my villa or home?
Not necessarily. Most Phuket villas are grid-connected, so the grid acts as your virtual battery — you export surplus power during the day and draw from the grid at night. Batteries make sense if you want backup power during outages or have high evening consumption.
Who installs the system — do you use subcontractors?
No subcontractors. Every system is installed by our own in-house team following PEA/MEA standards, with full electrical documentation.
