Overview

Techno-economic assessment demonstrates hydrogel passive cooling boosts power generation across 2,539 solar photovoltaic sites, highlighting an effective strategy for climate resilience.

Key Points

To evaluate the effectiveness and economic viability of hydrogel-based passive cooling systems in reducing heat-induced performance losses across utility-scale solar photovoltaic stations.
Evaluated three hydrogel-based passive cooling configurations across 2,539 utility-scale photovoltaic sites spanning diverse climatic zones in China.
Modeled cell temperature changes, capacity gains, electricity yield enhancements, carbon mitigation potential, and financial payback periods under current conditions and projected climate scenarios.
Hydrogel cooling with a water supply reduced average operating temperatures by up to 7.28 °C in hot arid-steppe regions, increasing individual station electricity yield by up to 7.26%.
Across all 2,539 installations, the intervention produced a mean equivalent capacity gain of 26.83 GW and an annual mitigation potential of 32.80 Mt CO₂.
The system achieved a minimum payback period of 3.16 years while consistently maintaining cooling efficacy under future warming scenarios.
