Sunsis

Established in 2016, Sunsis offers engineering, maintenance, repair, monitoring and analysis services for the solar power plants located in Turkey and abroad.

Just as the 19th century being referred to as the coal age or the 20th century as the petroleum age, Sunsis believes that the 21st century will be referred to as the solar age. Established with this belief, Sunsis manages the production process based on the feedbacks it receives from the equipment at the solar power plants. It instantly identifies all the unfavorable circumstances which may affect the performance of the plant. It responds to the problems identified and performs periodical maintenance, and thus enables the plant to generate power with its highest performance.

Thanks to its experienced technical personnel specialized in their fields as well as the monitoring and analysis program it has developed, Sunsis provides investors – no matter where they are located – with the ability to access to immediate data of the plant, review the return on production, and assess the plant performance.
