Story summary
- The Hong Kong Polytechnic University and collaborators developed a hydrogel cooling coating for solar panels that increases power output by 13%.
- The coating reduces hotspot temperatures by 16 degrees Celsius.
- Hotspots can lead to solar panel failures and fire risks.
- The technology could offset 50% of power generation losses from hotspots.
- The hydrogel system raises solar panel costs by about 10.7%.
