International Solar Alliance (ISA) Announces Winners of SolarX Startup Challenge — Latin America & Caribbean Edition
BELEM, BRAZIL, December 9, 2025 /EINPresswire.com/ -- The International Solar Alliance (ISA) today announced 10 winners from 9 countries—six of them co-led by women—of the SolarX Startup Challenge: Latin America & Caribbean (LAC) Edition at COP30 in Belém, Brazil. The LAC edition of the Challenge—launched at COP29 in Baku—builds on the successes of the Africa and Asia- Pacific editions, which declared winners in 2023 and 2024. Together, the earlier editions have supported 50 startups from Africa and the Asia-Pacific, including India, through a monetary endowment and a dedicated acceleration programme. The LAC edition of the SolarX Startup Challenge marks a significant expansion of ISA’s footprint in this region.
The SolarX Startup Challenge aims to identify and support scalable, cost-effective, and high- impact solar innovations tailored to regional needs. The LAC edition attracted strong participation from entrepreneurs across the region, offering solutions that advance clean energy access, grid resilience, and emerging solar applications. Following a rigorous evaluation process led by industry experts, investors, and clean-energy practitioners, the winning startups were selected for their ability to deliver real-world impact and technological relevance.
“This year’s SolarX Challenge received 113 applications from 29 countries, reflecting the region’s growing interest in practical solar solutions,” said Mr Ashish Khanna, Director General, International Solar Alliance. “We are encouraged to see participation from both ISA and non- ISA Member Countries. Ten promising startups from nine nations across Latin America and the Caribbean have been selected for ISA’s structured acceleration programme, each receiving a US$15,000 grant to further develop and scale their solutions. Along with this support, they will have access to technical mentorship, investor networks, and capacity-building opportunities through ISA’s partners, helping them strengthen their work and contribute to wider solar deployment in the region.”
He added, “These winners illustrate how local innovation can meaningfully support the region’s energy transition. Latin America and the Caribbean hold significant solar potential, yet continue to face challenges in access, affordability, and resilience. The SolarX Challenge aims to bridge this gap by supporting entrepreneurs who are developing adaptable and impactful business models. ISA remains committed to enabling these efforts and advancing a more sustainable future for the region.”
The winners will now enter a structured acceleration programme, working closely with ISA, technical mentors, and regional partners to refine, pilot, and scale their solutions. ISA has also showcased the progress of its winning start-ups at major global platforms.
