LANZHOU — China has organized a solar energy training course for developing countries in tropical and subtropical regions.

Twenty people from eight countries and regions, including Ghana, Rwanda, Nepal and Kenya, began the course, which started on June 17 in Lanzhou, capital of northwest China’s Gansu province.

Sponsored by the Ministry of Commerce and run by Gansu Natural Energy Research Institute, the training will focus on the technology of solar photovoltaic (PV) systems, solar water heaters, solar building and solar desalination.

The 28-day course will include lectures, technical exchanges, economic and trade talks and on-site practice, according to An Xingcai, deputy director of the institute.

Nana Sarfo Agyemang, an official with the Ministry of Power of Ghana, said tropical areas have abundant solar energy potential, and China will help these areas make better use of the energy with its advanced renewable energy technology.

“With China being one of the leaders in renewable energies, we find it most beneficial to learn from her experiences,” said Marcellin Mupenzi, a senior executive of an energy development company in Rwanda.

China’s PV installation capacity amounted to 43.18 gigawatt by the end of last year, the largest in the world, with Gansu and Xinjiang in the northwest as the leading solar power generation base.
