I think it is. I am not talking of opening up a farm here. Was just thinking of setting up a s19 or two of them. I have 3 air conditioners (2 ton) installed in here. They work just good. Not any good with electricity, but two s19 would draw upto like current for 5 air conditioners. This house runs fine with 3 acs, a geyser, a refrigerator, and a TV. Thats all where my electricity goes right now.
Since you are well aware of what you are planning to do what is the mental blockage, it is funny you asked whether it is moral because if you think otherwise you will not even think about doing. If i am in your shoes the things i do is my hobby and if i need to pay any extra for my hobby i am happy to pay them and inform my superior about my hobby and move on with it rather than thinking too much
