Average US home use is .2 kW, which over 24 hours is 29 kW-hr, plus you need extra for cloudy days, peak demands, and to charge batteries. You have to decide off-grid or on-grid, and if you want to (and are allowed to) sell excess power to the power company. Off gird, the cost of batteries and charge controller are a large part of the cost. On-grid, you have to purchase equipment approved by the power company to match your power with the grid. Panels will cost about $3 per watt, so for 000 watts that is $3000. Double that for installation, then add in cost of charge controller, inverter, batteries, etc. The last items depend on your alternatives, see paragraph above. .s

Batteries the quantity determined by your needs. Last an inverter to convert 2 volts DC to 20-220 AC. The size shown in watts is determined by you needs. If you plan to use it all the time you will have to have piece of equipment usually part of the inverter to sync the inverter up with the public utility and any power you don't use gets sold to the power supplier.

What is the anatomy of a solar panel?
- You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.s
