01 — About us
Solar ESS was founded to promote solar energy adoption and sustainable practice across Thailand, raising awareness of energy use at both the household and industrial level.
The sun's output is renewable and sustainable, expected to last as long as the sun itself — equally accessible to everyone, with no depletion of other resources required to use it. Solar remains one of the most affordable paths to energy independence, and with the right support and incentives, that independence is within everyone's reach. Solar ESS is committed to sustainable energy practice in business, learning from real experience on the ground in Thailand to better understand local energy challenges and empower the people we work with.
Clean generation that reduces reliance on fossil fuels and grid strain.
Engineered systems built to run safely through Thailand's climate, day after day.
Lower daytime electricity costs that pay the system down over time.

Head office of the network: design, installation, monitoring and long-term care of solar power.
With 15 years installing mostly 300–1,000 kW sites, ESS DEE Solar connects over 30 installation teams across Thailand.
SAP Group has driven much of Solar ESS's design and technical support work, focusing on knowledge-sharing that helps customers become fully energy self-sufficient.
Making solar power accessible to everyone, and bringing it to remote communities without electricity.
Puts education before sales, travelling the country to show people that solar is the path to energy independence.
Extends the mission to central Thailand while incubating young electricians, with up to 30 projects installed.
A key driver of solar across the islands of Krabi, also advocating for reducing waste in its local community.

What the owners say
Solar ESS took care of the full power set-up on our farm, from start to finish: roof brackets with custom stainless steel piping, crossing the creek and hauling batteries, swapping inverters, and smiling at every stage. They gave clear advice, technical and software support, and creative, affordable solutions, and they even check in when the monitoring app shows something abnormal. You can get good hardware and software anywhere, but it’s the people and killer service of Solar ESS that make the whole process 100% worthwhile.
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.
My wife and I are very pleased. He was also very informative and explained every step of the process. I highly recommend him, and he speaks perfect English.
