Hi there - looking for some help as I can't find an answer to my specific question online:


Every year I claim a portion of the power that my home uses for work related activities (technical equipment that runs 24 hours a day, plus home office (work from home).


I'm looking at putting solar power in with a battery which will clearly reduce my quarterly bill somewhat - but I have been told that where still likely be an out-of-pocket expense.


As an example - lets say my bill was $1000 per quarter, and I claimed $500 (50%) as a work related expense (I don't - but just to keep numbers simple. I run power usage meters on all the devices, so I know exactly how much is used).


After solar is installed, my out-of-pocket expense is now just $500 per quarter. Is it possible to still claim the full $500 as a deduction or can I only claim 50% of that (just like I was doing prior to solar installation). The way I'm looking at is if I didn't need to run this home equipment for work, I wouldn't be out of pocket at all. My meter usage will still tell me that it consumes $500 worth of power each quarter and that is what my bill will be $500.


Just wondering how others might differentiate between what solar/battery provides and what you have to still pay out of pocket.


Hope this makes sense :)


Kind Regards


Justin
