Can a house run on solar power alone? @ BlurbSlate.Com

For a typical, modern house to run exclusively on solar, all they really need is a way to store the power when the sun is not shining. That is possible, especially now that the Powerwall is available, but those are still very expensive and only store 5-10 hours worth of power, depending on your home's energy use.

Does solar really save you money?

Do solar panels really save you money? The simple answer to the question “do solar panels really save you money?” is yes. Direct hours of daily sunlight and the size and angle of your roof are both important, but local electricity rates play the biggest role in determining how much solar can save you.

Do I get free electricity with solar panels?

Solar photovoltaic (or PV) panels convert the energy in sunlight into electricity, and this is effectively free electricity that can be used in your house (once the cost of installing the panels has been taken into account, of course). Surplus electricity is exported to the grid.

How much do solar panels cost for a 2000 square foot house?
