I have just gone through a 10 month process to take my home and office off the grid. As of May 20th, 2015, 100% of my electrical power is generated by solar panels on my roof. I chose, to go into a Solar Lease for the install of the panels, at an out of pocket cost of Zero. I will still be paying for the electric generated by the panels at a cost 33% of the going utility rate and the rate will be fixed for the next 20yrs. If you have any questions or would like recomendations please feel free to contact me and I will attempt to get back to you in a timly fashion or post a blog answering groups of questions.
