Can Solar Energy power the entire house?Our home produce 350-400KW per months. How many solar panel and Battery do we need to produce enough energy from the house?

Absolutely. If your home uses up to 400kwh a month, the first step is to try to reduce that even more. For every 1 you spend on conservation, thats 4 less in solar expense. But lets say youve already conserved as much as you can
Depending where you are, you would need about 4000 watts of solar electric panels. Since you are currently connected to the electric company, theres no need for batteries. Just make as much as you can during the day, and sell any extra power back to the grid. Then at night and on cloudy days, you just buy it back from the grid, same as you do now. With net metering, the electric company keeps track of how much you sold and how much you bought, and you can end up zeroing out the bill (or at least having it down to just delivery charges, fees, and tax). Different electric companies have different rules, so actual mileage may vary. Heres an example of a 3000W grid tied system, youd just need another 1000 watts.

You can see for yourself on the grid-tied calculator at Http://www.altestore.com/store/calculato
If you do want to cut your connection to the electric company and store your power to use at night, youd go to the off-grid calculator to also figure out the battery bank size. Http://www.altestore.com/store/calculato With 2 days battery backup, youd need about a 1500 amp hour 48V battery bank.
Also take a look at solar water heating, its a very cost effective way to get your energy usage down. Http://www.altestore.com/store/Kits-Pack
What would it cost to install solar pannels on a 1500sq. Ft. Home?
I live in Maine and my electric bill is just under 200 mo. And mt oil bill is @150 mo. The home is 1500 sq. Ft. And we are in our late 60s the home has a steel roof, is a manufactured home with a shallow roof pitch.

You need to look at your electric bill and see how many kilowatt hours, or kwh, you use a month. Im not sure what you pay per kwh in Maine, but lets guess it is over 1000kwh a month. You can go to a calculator like Http://www.altestore.com/howto/Tools-Cal to see what it costs for installation. Keep in mind most people dont generate 100% of their use, you can just generate some and buy the rest like you do now.
However, you should first look at conservation. For every 1 you spend conserving energy, thats 4 less you need to spend on solar. Its 1/4 the price to save energy than to make it. How well insulated is your house? Are you heating the just your house, or the neighborhood as well? I bet if you put the first chunk of money into improving the insulation of the house, your oil bill would drop dramatically. Look for an energy auditor in your area to do a blower door test on your house. That will locate the leaks. Http://www.mainehousing.org/ENERGYAuditS There are amazing tax incentives now to help pay for weatherizing your house. I tightened up my house, and my heating bill cut in half.
How many different things do we use solar power in?
Theres.. Solar cars.. Solar heating for pools, solar panels What else?

Solar thermal energy using glycol to heat water.
Integrating solar photovoltaic energy into your home or business power.
Large independent photovoltaic systems.
Photovoltaic cells for producing electricity (very expensive to
set up but maintenance free)
solar water heaters very popular in several countries to produce hot water
solar cookers for cooking food
in farming to run isolated pumps for irigation,and normal power use of residences of isolated farmers
solar cells on the street lamposts
Prototype cars
houses (CA. Has enacted a big solar power push)
telephones
computers
calculators
* Small electronic devices like calculators.
* Many highway signs and other mechanical devices which are left outdoors in sunny areas are now equipped with solar panels-look as youre driving along a highway.
* Homes & buildings. Even without solar panels, most buildings use solar energy for some heat. Whenever we open the shades on a cold and sunny day, we are using solar energy to heat the room.
* Plants. Almost all plant life on earth uses solar power, and thus, almost all life on earth is fueled, indirectly, through solar power.
* Power generationboth for private homes, commercial bulidings, and actual power plants. There are a few solar power generation plants, although theyre not common. Even some BP gas stations are now equipped with photovoltaic cells on the roof covering the gas pumps!
