Engineers who look after
your roof for 25 years

ARUNA ENERGY started in 2014 with three electrical engineers who believed Thai factories should make their own power. Today we are 120 people, with 14 in-house installation crews and a 24-hour monitoring centre.

We do not subcontract. Every system is designed, installed and maintained by our own staff, so we can stand behind all of it.

What we hold to

Safety first

Every crew is trained for working at height and can stop work whenever it is unsafe.

Honest numbers

We forecast from real data and report actual results every month.

In it for the long run

Systems last 25 years, so we stay after installation.
