About Our Company

Worldwide, the importance of conserving energy to protect the environment and reversing global warming has become integral to the survival of the planet. In 1982,

Alpha Engineering Services recognized the value of harnessing the power of the sun and collaborated with the National Engineering Research and Development Center of Sri Lanka (NERD) to develop a solar water heating system that would play a pivotal role in the area of energy conservation in Sri Lanka. The success of this venture and the birth of Alpha Engineering Services’ brand, Solar-Therm, led to the recognition of the company’s work with an award of ‘Pioneering Industry Status’, by the Government of Sri Lanka.

Following this national honour and recognizing the limitations of traditional hydropower, the visionary the management, renamed the company, Alpha Thermal Systems (Private) Limited, to explore the potential in alternative and economical energy resources. Thereafter, the manufacture and marketing of Solar-Therm was transferred to Alpha Thermal Systems (Private) Limited.

From modest beginnings, Alpha Thermal Systems (Private) Limited began to introduce new standards of efficiency and quality controls to the local solar energy industry. This company’s dedication to continuous research, development and innovation has led to the existing leadership status of Solar-Therm in the local market.

Solar-Therm has become a 100% solar energy solution provider, helping the company diversify into many other energy conserving processes. In 2003, Alpha Thermal Systems (Private) Limited, created a sister company, Alpha Solar Energy Systems (Private) Limited, to increase focus and improve
customization of its solar photovoltaic activities.
