Question:

What solar panel do I need?

During the summer my house uses about .47 kw/h I am wondering what solar panel do I need to cover most or all the electric bill. A link would be helpful too :)

Answer:

They make panels now that put out 25 watts so about 8 panels would do it.
The correct answer depends on how much total energy you use during the day and whether or not your utility allows something called net-metering. In net-metering, if you make more power during daylight hours than you consume, the meter goes backwards. Then at night the meter goes forward again. With net-metering you only pay for the difference.
Are you saying your house continuously draws about .5 kW average all day long? That's 36 kWh per day, if so. This is about double what our house uses year-round, so if you lived in our area, that would be a 6 kW system. The only way to nail down a good number is to get a quote from a local solar installer, though.
Your okorder /.. A solar panel of 40-50 square meters should suffice, at least in summer when the sun is high in the sky. It's about 500 square feet, or about 20 times 25 feet.
