Off-Grid Solar & Battery Storage
Energy independence for Ko Phangan. No more blackouts, no more surging electricity bills. Solar and battery systems that keep your power on around the clock.
Why Battery Storage on Ko Phangan?
Island life comes with unique energy challenges. Battery-backed solar addresses every one of them.
Frequent Power Outages
Ko Phangan experiences regular power outages, especially during storms and peak tourist season. An off-grid or hybrid solar system with battery storage keeps your property running regardless of grid status.
Remote Locations
Many properties on Ko Phangan are located in areas with unreliable grid connections or no grid access at all. Off-grid solar is the most practical and cost-effective way to electrify these locations.
Energy Security
Dependence on a single power source is a risk. Battery-backed solar provides a reliable secondary power supply that protects your home or business from grid instability.
Rising Electricity Costs
PEA residential tariff (Type 1.1.2, from September 2026 bills): 3.0000 THB/unit for units 1–200, 4.1584 for 201–400, and 4.3583 above 400, plus Ft (0.1623 THB/kWh for Sep–Dec 2026) and 7% VAT. Generating and storing your own power locks in a predictable energy cost and shields you from future rate increases. Sources: PEA corporate news and Ft surcharge Sep–Dec 2026 (PDF).

Choose Your System Type
We design three types of battery-integrated solar systems. Each serves a different level of grid independence.
Grid-Tied with Battery Backup
Most popularStay connected to the PEA grid while having battery storage for outages. Solar charges your battery during the day, and the grid fills any gaps. During blackouts, the battery seamlessly takes over your essential loads.
- PEA-approved export/net-billing where available
- Battery backup during outages
- Lower cost than fully off-grid
- Best of both worlds — grid stability plus independence
