Conergy, a Germany-based solar-energy company, has secured a contract from Thailand-based Siam Solar Energy 1 to build three photovoltaic plants with a total installed capacity of 31.5MW.

The three projects, spread over an area of about 790,000m2, are located in the provinces of Suphanburi and Kanchanaburi in western Thailand, and will have capacity of 10.5MW each.

As per the terms of the agreement, Conergy will supply components, including 130,000 Conergy "P-series" photovoltaic modules and will also undertake the planning, engineering, design and installation responsibilities.

Conergy is collaborating with Annex Power and Ensys for the construction of the three solar plants.

Conergy CEO Philip Comberg said that the company wants to significantly expand its large project business.

"In addition to the growing Asian markets such as Thailand, we are focusing our efforts on the American solar market," added Comberg.

The three solar power plants are scheduled to be completed in May 2013 and are expected to generate about 45,200MWh of clean electricity annually.

In 2012, Conergy began constructing two power plants for Siam Solar Energy 1, a subsidiary of Thai Solar Energy Company, with a total installed capacity of 21MW.
