As an engineer, hybrid works best for many of us.
Design phase can be wfh with some in-person idea sessions or important meetings because I have yet to be at an online idea session that was as productive as in-person being able to draw things out and visualize better, and people tend to not speak up or just check out and agree at the end in online meetings.
Testing phase has to be mostly in person for lab tool access and collaboration on physical things.
I have worked with a contractor that did everything from home and had a whole home lab, but it was a big time sink and cost shipping parts back and forth 5 times and you couldn't physically probe behaviors together which leads to slightly different setups and sometimes different results.
Socially I moved to a place where I had no friends so I like getting social contact at work since in Belgium, it is extremely difficult to make new friends after you are done with school because of a culture of not talking to anyone else unless people are obnoxiously drunk lol. I like wfh on overwhelming days and in-person on days where I want more social contact.
That being said, I work 100% in office now because I live a 12 minute bike ride from work, so very easy.
Generally export to the grid. Farms don't use 500kW-1MW of energy usually.
Since industrial farms and oil company corruption have killed produce profits for human consumption, selling the energy is often more viable financially than the crops that grow under it, especially as far as upkeep with the absolute proprietary planned obselescense shit show that is the Agri equipment industry. Not to mention the insane Monsanto seed corruption and abuse. Many farmers are operating on a loss which has lead to regional monopolies as megacorps buy up bankrupt farms.
Going the agri-solar route could be the saving grace for many many farms. (Where it is viable at least and transmission is doable)
