Knob & tube = new electrical runs, possibly a new service & a circuit breaker panel.

When the electrical panel you had wouldn't support the items you wanted to add to it, you should have recognized that; not necessarily that it wasn't enough, but that there might be an issue with it and to have an electrician look at it before you made the purchase.And again, these are not overages, these are change orders; not knowing the difference in another indication you got in over your head.

The building however has old fuses in the electrical box panels and the entire HVAC system is outdated and will probably have to be replaced soon.

There are dozens upon dozens of if not hundreds of companies that can service / test / maintain the panel.If you call Napco, they should connect you with their 'authorized' service dealers and you can also reach out to any provider to see if they will service the panel

But I was thinking you could use the top of the storage buildings for solar panels.

Then we turn on circuits in Common panel for lights to work in vacated apartment.

It is as simple as that.On a side note, I attended my REIA meeting last night that had a panel of short sale experts on it.

I can not beat $15 for a raised panel door.

Electrical wire, the door to the electrical panel that was missing was 175 bucks on ebay because it's obsolete.
