I'd like an estimate for installing solar power for everything electric in my 4,644 square foot home.

We have a historic home in Baltimore with a flat pitched roof.I am interested in finding a solution for our power issues even if it takes a while.Hopefully you can let me know all the options from buying to leasing and the different incentives for each federally and locally here in Maryland.

Generally residential solar costs about $3-4/watt.

A roof area of your size could hold up to 30kw or 30,000watts of PV. You probably don't have all this roof area open though and also probably don't need that much solar to zero out the energy for your home.

In my experience a home of your size probably needs about 20kw or 20,000watts to be totally net zero on an annual basis. To provide a more detailed proposal and estimate please fee free to contact me.
