Voices from our customers.

From Flood to Sunlight

Once the installation was complete, I was genuinely impressed by the team's professionalism and meticulous attention to detail. Despite having no technical background in solar systems, I feel completely confident and at ease knowing my home now has safe, reliable electricity.

The practice

A contractor's discipline.
An architect's eye.

Solar ESS designs and installs solar energy systems across Thailand and Southeast Asia. We treat every roof as a structure first and a power plant second, engineering single-line diagrams, load profiles, and hardware selection to the same standard as the building beneath them.

We specify Aiko Neostar panels, Solis hybrid inverters, and CHINT protection: documented, permitted, and built to outlast the warranty.

FAQ

Straight answers.

Does Thailand give net metering to homeowners?

Not true net metering. Thailand uses net billing: the solar power you use yourself replaces grid power at the full retail price, and the surplus you export is bought at a fixed lower rate of 2.20 baht per unit.

How long is the payback for a home?

Typically about 4 to 7 years for an on-grid system when most solar is used in the daytime. Batteries lengthen payback but add backup and night-time use.

Is there a tax benefit?

Yes. A personal income-tax deduction of up to 200,000 baht applies to on-grid rooftop systems up to 10 kWp connected between 3 March 2026 and 31 December 2028.

Will my solar work during a blackout?

A standard on-grid inverter switches off for safety when the grid fails. You need a hybrid inverter with a battery and a backup circuit to keep essential loads running.

How much maintenance does it need?

Very little. Panels are usually cleaned once or twice a year, with one yearly inspection of wiring, protection devices and earthing.

Can the inverter run without a CT?

Yes for a plain on-grid inverter that is allowed to export. No for a hybrid inverter or any system that must limit export: the CT is the inverter's only way to see what the building takes from the grid.
