Three hours was suggested as the typical install time, but it took me 16 hours -largely because of the complication of our multiple panels and also because I redesigned the circuit transformer layout several times as I learned what was possible and was not.We are also experimenting with www.Sense.com ($300). 

You also need to check with the utility companies and get cost estimates from them for availability, fees, hookup charges, transformer and power line/power pole locations or relocation requirements, water, sewer,gas, cable etc You will need ball park cost estimates from site work contractors for site work, roads, installation of utility lines etc.This is just a broad high level run down of the process but should give you some things to start with and think about.

I transformed the back office into an efficiency to increase the number of rents from the property.

Municipalities within Milwaukee, neighborhoods and school districts are a much better reference.I am both exited and frankly a little bit surprised about the transformation we are seeing. 

Through the electrical line of the heat pump blowing the transformer.

I still own properties in Bloomfield and it has gone through a serious transformation in the last few years.
