Combine that passive cooling with a heat pump to create hot water from PV panel waste heat and you'll both gain efficiency as well as a hot water source.

- thinkcontext 7y agoHere's a DIYer that did that but instead of hot water used a minisplit https://renewablesystemstechnology.com/solar-heat-pump-system.html https://renewablesystemstechnology.com/solar-heat-pump-syste...
- Yetanfou 7y agoAlthough a simpler solution to build due to the absence of liquid coolant I'd still choose a combination of PV-panels with liquid-based collectors attached to the back as this also makes it possible to circulate warm coolant through the collector to de-ice/snow the panels in wintertime.
