Showcase new evidence from Tuvalu on the interaction between rooftop solar photovoltaic systems and harvested rainwater quality, highlighting how climate mitigation and adaptation objectives can be advanced together while safeguarding water security, public health and resilience in small island states. As Tuvalu advances its transition to renewable energy while relying almost entirely on rooftop-harvested rainwater for drinking water, important questions arise about the interaction between solar photovoltaic (PV) systems and water quality. This side event will present findings from Tuvalu's first technical assessment of rooftop solar PV systems and harvested rainwater quality, examining the opportunities, risks and policy implications of the water energy nexus in a climate-vulnerable atoll nation. The session will highlight lessons learned from field investigations, stakeholder consultations and water-quality testing undertaken across Funafuti and will explore how small island nations can pursue climate mitigation goals without compromising water security and public health. Discussions will focus on integrated approaches to climate adaptation and mitigation, renewable energy deployment in Small Island Developing States (SIDS), and practical recommendations for policymakers, development partners and communities. The event will provide a platform for sharing evidence, exchanging experiences and strengthening collaboration on resilient, climate-smart infrastructure that supports both clean energy and safe drinking water.
