WHA Solar Proven Track Record


WHA Solar Proven Track Record: Our successes with WHA Solar installations

Working towards green and clean sustainability

WHA Solar is actively shaping our energy future and business operations towards sustainability. Part of WHA Utilities & Power (and the broader WHA Group), our approach from the very beginning has been to provide innovative solutions for a more sustainable sector across Thailand’s industrial estates.

Beginning initially with solar rooftops on factories and warehouses, WHA Solar’s options have also expanded to include solar farms, solar carparks and solar floating to industrial and commercial clients. Many warehouses, factories and industrial properties have now transformed and integrated clean power production into their everyday operations. They enjoy cost savings on electricity, combined with the knowledge they are significantly decreasing global greenhouse gas emissions and air pollution, and relying less on fossil fuels.

Since commencing, WHA Solar has grown solar installation capacity to more than 160 MW and worked on over 90 projects with a diverse range of customers throughout Thailand. The total annual savings has exceeded THB 1.15 billion per year.

We work with properties of all sizes, starting from 0.5 MW and seek to minimize their environmental impact, while maximizing efficiency and performance. WHA Solar offers all-inclusive service packages with full installation and ongoing monitoring and maintenance under contract terms, with zero upfront costs and immediate savings.
