Mining with domestic solar power

[SolarBot]

I have a 3.9kW PV array on a domestic property in the UK. I don't use much of the electricity it generates so I am looking to get into ASIC mining with a single device. I have looked at the online calculators, but what puts me off buying something like a Antminer S9 (or S17 if I can get one) is the noise and the fact it'll only be profitable when it's sunny. This is because my electricity price is quite high at 0.15 GBP/kWh (0.19 USD).

I might build an insulated box for the noise issue or later on do some dielectric cooling. Suggestions welcome here though as the unit has to be quiet.

My real question though... Has anyone used, or is there, some kind of solar switching device that can push power to the ASIC miner when I am generating more solar power than I can use? Can these units stand a few daily power cycles and do they lose anything significant they have been working on if they are shutdown mid-calculation? Would this just be a daft thing to do?

Thanks in advance.

There is nothing special about powering a miner ,  so think of it as if it's a TV or a Fridge, if you have enough power to power it up, then all good.

there is nothing you going to lose for not being able to mine 24/7 , however , there are a few payments methods , the best that suits you is PPS = Pay per share , this will ensure that you get paid for every share you submit when your miner is on, here is a simple example.

let's assume your miner submits 1 shares per second , and each share = 0.00001 btc  for every second your miner is on, you get 0.00001 btc, when you turn it off, nothing of the previous work would have gone missing.

as far as the noise goes, there are some silent boxes and tweaks that a few members here have showed, you can search the forum , but keep in mind these things are loud , so no matter how much you try to make them quite, the fans will always make some noise.
