Following up on my 10 kW solar and 3 kW Bitcoin miner example, would underclocking be worth considering instead of running the ASIC at full power?

With no battery, surplus solar would change throughout the day. I’m wondering whether running at a lower power setting for longer would make more sense than mining at full power for a shorter window.

The numbers I’d want to compare are actual wall power, hashrate, and efficiency at each setting. I’d also include a hosting quote from oneminers or compass mining as another option, using the same hardware and mining assumptions.

Has anyone measured their Bitcoin ASIC at different power settings? Where did you find the best balance between watts, hashrate, and daily BTC earned?
