German-Vietnamese City Partnership – A Solar PV System for Hoi An

In 2013 the two cities of Wernigerode and Hoi An signed a city partnership, comprised in part of shared common climate change efforts. Hoi An participates in the Municipal Climate Partnership project implemented by Engagement Global gGmbH in cooperation with further initiatives and communal associations, funded by the German Ministry for Economic Cooperation and Development (BMZ). The two cities are developing a work agenda for the coming years.


In the context of this partnership, the city of Wernigerode has now acquired funding for a solar PV system to be installed on the roof of the city department for culture and sports, right at the entrance to the UNESCO World Heritage old city center.

From October 19 to 21 a delegation from the city of Wernigerode visited Hoi An and signed the cooperation contract for the PV system. With an estimated capacity of 38 kWp, the system is expected to support the electricity demand of the center of culture and sports as well as power the public lantern and sound system of the historic city center. To guarantee these consumers continued solar energy supply in the evenings, a certain amount of battery storage capacity will be integrated to the system design.


During the visit, a solar installer from Wernigerode, along with representatives from the German city’s communal utility, had the chance to examine the available roof areas, electrical facilities and grid connecting points.

RB – Renewable Energy Consulting advised the two parties regarding feasible system designs, accompanied the delegation on their inspections and mutual exchanges, and presented information on solar energy development and framework conditions in Vietnam and Germany.

The installation of the PV system is planned for mid-2017. For more information see here (in German).
