Built in Thailand. Here to Stay.
Meet the local team behind dependable solar and battery installations across Thailand.
Solar Solutions Designed for Long-Term Value
Our interest in solar technology began in 2018. We saw an opportunity to provide customers in Thailand with lower electricity costs, dependable backup power and access to cleaner energy.
Since then, Chaweewan Group has grown into an experienced local company with its own electricians, electrical engineers, project management and specialist rooftop installation team.
We do not depend on random workers or temporary subcontractors. Our employees are trained to follow our standards for quality, safety and professional workmanship.
A strong company culture and low staff turnover allow our team to develop their skills, work effectively together and take responsibility for every installation.
A Solar Installation Is a Long-Term Investment
For most customers, the result over time is what matters most. Our goal is to design systems that provide dependable performance, useful backup power and long-term savings.
Achieving this is not simply about choosing the cheapest installation. It requires suitable equipment, professional electrical work, correct system design and dependable after-sales support.
Many risks associated with solar are connected to poor workmanship, unsuitable electrical installations and low-quality equipment. Choosing an experienced company with its own trained team and established suppliers helps reduce those risks.
Chaweewan Group is in Thailand for the long term. Our goal is aligned with the customer’s: a dependable system that continues delivering value for many years.
We take responsibility for the complete installation—from system planning and electrical work to commissioning and after-sales support.
