| Peltier cooling doesn't get used much in solar setups because it uses a lot of power and does so 100% of the time. A typical Peltier cooler might run 4-5A continuously whereas a compressor cooler might run 2A 30% of the time and turn off the rest of the time. The 100% duty cycle issue can be alleviated by wiring in [[https://amzn.to/2WJg4tu|a 12v thermostat]].((assuming it would ever get cold enough to shut off. )) | Peltier cooling doesn't get used much in solar setups because it uses a lot of power and does so 100% of the time.

| | Read the manual before purchase to see how long it can be run at a stretch; fans are a common failure point when run 24/7. |
