On behalf of the Partner Organizations, we would like to thank everyone who supported and attended the 4 th edition of the International Conference on Solar Technologies and Hybrid Mini-Grids to improve energy access – s-@ccess, held in Mallorca, Spain from 26 to 28 April 2023. As in previous editions, the main objective was to enable exchanges between practitioners from the field, academia, financiers, and development institutions committed to decentralized energy access and local development. The conference allowed us to share experiences on all solar technologies, learning from each other, and networking. The conference was held in a face-to-face format with 136 active participants, from 35 different countries and 5 continents! The level of the presentations and discussions was so high that it has made us feel privileged to chair such a unique event. The program included 69 lectures, 21 posters and 6 round-table discussions. In addition two side-events were also held: The Energy Access Innovation Lab organised by WISE (Canada) and the ESMAP (WB) Mini-grid workshop on Scaling up Mini Grid deployment by a factor of 10.

As a special highlight a Solar Lunch was organised, and participants could taste meals cooked in solar cookers of different technologies. We received very positive feedback from not only on the relevant presentations and discussions, but also on the networking opportunities in our Innovation Lab, during the Welcome Reception, and at the Gala Dinner at the Port of the city of Palma.

We, as chairpersons would be pleased to welcome you again at the next edition of the S-@ccess conference.
