Awards & Fellows

Each year, we honor individuals making significant contributions to ASES as well as general contributions within the field of solar and renewable energy.

Our annual awards recognize renewable energy scientists and professionals for outstanding contributions at all career stages. Nominators and awards committees are asked to consider the diverse and international nature of our field. ASES always seeks nominations of members of underrepresented groups in topics relevant to society, such as the Women in Solar Energy and Yellot Student Scholarship Awards. ASES supports the principle that awards should include factors of justice, equity, diversity, and inclusion. ASES confers seven separate awards annually and regularly names new Fellows.

Please nominate a 2024 awardee through the pages below by February 15, 2024.

During the SOLAR 2023 Awards Banquet in August 2023, Carol Weis received the Women in Solar Energy (WISE) Award from Marlene Brown, WISE award subcommittee chair, and Carly Rixham, American Solar EnergySociety (ASES) executive director.

Please follow the links below to get to the nomination information and forms for each award.
