Conclusion: Assuming it's reasonable to connect to the grid so do so initially. Money should first be spent on reducing consumption as much as possible and then determine if it makes sense to invest in solar panels for the remainder. Depending on what is producing the grid electricity the carbon footprint of solar panel production might actually be greater than using the grid. Regardless build flexibility into the system so supply can come from multiple sources and use batteries to increase efficiency. Wind power generation might also be an option depending on the available land. For wiring basically just need to make sure everything is done to code. Wireless power transmission is cool but not yet commericially viable.
Cost: $15,000 for wiring and outlets.
