Ms. Ma has more than 20 years of experience in finance and internal control areas, including over 15 years of management experience.

Mr. Yumin Liu, Chief Executive Officer of ReneSola Power, commented, “We are excited to welcome Maggie back to ReneSola Power as a board member. Her strong executive leadership experience, deep knowledge of the solar industry, and solid experience in financial operations will benefit the Company as we grow and expand our project pipeline. I look forward to partnering with Maggie along with our other Board members, as we continue to advance ReneSola Power’s mission to become a leading global solar power project developer.”

Mr. Liu continued, "Wade has made significant contributions to ReneSola Power since he joined the Board in October 2019.
