local manufacturer of solar panels!

Located in Chiang Mai, the Oelmaier Technology company was founded by its Managing Director Mr Uwe Konrad. The long established solar energy company has been providing a range of energy efficient solutions for applications ranging from Photovoltaic Grid Inverters for solar farms, solar roof systems and wind turbines; up to LED lighting and solar water heating systems.

Developing Solar Water Heaters. As well as developing applications for Photovoltaic Grid Inverters Mr Uwe also developed state of the art Solar Water Heating systems, using best practice fabrication in Chiang Mai in conjunction with his German engineering skills to produce high efficient absorber panels of a top quality made from copper. Demand for these products and their installation reached a level where it justified investment in new manufacturing capacity and a focused marketing service throughout northern Thailand, leading to the formation of Chiang Mai Solar.

Uwe Konrad heads now a team of specialist manufacturing engineers, sales, distribution and installation staff. Chiang Mai Solar has emerged as the leading specialist hot water solution provider in the region and the only company that integrates customer requirement analysis with fabrication, distribution, installation and after sales service.

With rising energy costs worldwide and increasingly urgent action required to reduce carbon
emissions, Chiang Mai Solar makes very good sense, environmentally and economically.



Managing Director Mr Uwe Konrad (Engineer in Power Electronics) has been involved in the Solar Energy Industry since 1997, giving him more than 14 years extensive experience.

As Foreign Affairs Manager at the Chiang Mai Technical and Commercial College (CM-Tech), he not only set up several international academic co-operations, he also designed and produced light weight photo voltaic (PV) solar modules to be used on a 3-wheeled, environmentally sensible, solar vehicle powered by solar cell generated electricity.

An ecological first for Chiang Mai.

In the following years Mr Uwe realized numerous academic and technical projects, ranging from teacher training to international bachelor degree programs with British and German Universities including the design and development of a prototype high powered 2-seater sports car.

Within the staff qualification program of the German University of Applied Sciences of Wiesbaden (Fachhochschule Wiesbaden) at CM-Tech, Mr Uwe meet the famous Prof Dietrich Dahlinger the inventor of the "transformer less inverter" which is now the standard worldwide technology to feed electricity from Solar and Wind to national power grids.

Based on this friendship and the good relations with Prof Dahlinger, Mr Uwe was licensed and encouraged to forward the technological know-how for the "transformer less inverter" to his business partner (within the ARC Co., Ltd.) Mr Wolfgang Oelmaier of Oelmaier Industrie Elektronik GmbH in Germany, now Oelmaier Group, for further development and final production of the PAC Inverter series.

Oelmaier Group is now one of the most technically advanced Solar Inverter manufacturers in Germany.

In 2004, Mr Uwe established the first small scale production of Solar Water Heaters in Chiang Mai and this enterprise has now grown and developed into the present Chiang Mai Solar, an energy developer who is now offering a full range of solar solutions, solar thermal and photo voltaics, to improve the world's environment.

"The strength of CMS lies in the fact that CMS is a manufacturer rather than only a trader! We know the product and its features better than others do. We are able to offer each customer a customized solution and can service where others fail."
