home solar power systems
how much would it cost to power a 1000 sqft. home with a solar system 100%.?
Including batteries for night time power.
It's a common misconception that residential solar system sizing is based on the size of your house. In fact, the best way to determine this would be to take a look at your electricity bill. You are looking for the number of kilo-watt hours (kWh) that your home uses per month. It would be best if you could look at a bill that possibly has a bit of "history" on it, showing your usage over a year so that you could get a good idea of your average energy usage per month. If you don't have a power bill to go off of, you can always do a loads list calculation and figure how much electricity you would need to generate.

The next factor that will come into play is the location of your home. Each location on the planet has an average "solar insolation value". This will be the average amount of "noon day sun" that your home gets each day.
These are the two factors that will determine the size and cost of a residential solar system. Incorporating batteries into a system of this size can be very expensive ($3000-$40,000 for the batteries alone) and could require monthly maintenance.
A ballpark cost for one of these systems would be anywhere from $10,000 to $50,000 depending on your usage and solar resource. If you want to get a better idea of a system that would power your own home, plug your info into an online calculator.
