Why go solar on Koh Phangan?

The island runs on diesel generators and mainland grid. Electricity is expensive. The sun is free.

Frequently Asked Questions

Everything you need to know about going solar on Koh Phangan.

Do I need permits to install solar panels on Koh Phangan?
No permits are required for rooftop solar installations under 200kW in Thailand. Bustan Energy handles all PEA (Provincial Electricity Authority) paperwork for net metering connection.
How much can I save on electricity with solar?
Most customers save 50-70% on their electricity bills. Hotels and resorts spending ฿50,000-200,000/month typically see payback in 3-5 years, with 25+ years of free electricity after that.
What is a PPA (Power Purchase Agreement)?
A PPA lets you go solar with zero upfront cost. Bustan Energy installs and owns the system on your roof, and you buy the electricity at ฿4.50/kWh — significantly less than PEA grid rates of ฿5-7/kWh.
How long does solar installation take?
Typical residential installations take 2-3 days. Larger commercial projects (20-50kW) take 5-7 days. We schedule around your business operations to minimize disruption.
Do you install EV charging stations?
Yes! Bustan Energy installs Level 2 and DC fast charging stations for hotels, resorts, and commercial properties. EV charging is a growing amenity that attracts eco-conscious travelers to Koh Phangan.
What solar panels and inverters do you use?
We use Tier-1 panels from Longi, JA Solar, and Canadian Solar with 25-year warranties. Inverters are from Huawei, Growatt, and Enphase depending on system design. All equipment is certified and warrantied.
