About

For the last two years I have been working as a Head of Operations in the Polish branch of a company from the photovoltaic industry- SunPro Power Co. Ltd. My main task was to introduce to the Polish market a completely new brand of photovoltaic modules - SunPro Power. Thanks to close cooperation with the Chinese factory of photovoltaic modules - Yuhuan Furui Energy Co., Ltd., we've managed to create and strengthen a new brand, able to compete with the largest producers in PV industry.
