Solar panels and calculations?

1) what is absolutely needed to hook up a solar panel to grid tie, what permits and/or inspectors are needed?

2) if we know how many KWH's we use per month, do we just divide by number of hours per month to find out average KW usage?

3) what is an estimated ratio of DC to AC transformation/convertion @ 30 C?

4) do the solar panel voltages have to be the same? what would happen if the voltage going into the house is greater/lower than that of the house's defualt voltage

5) for added chance of getting 10 pts add some contrators that do business in ohio for installing solar panels or sell them

Answer:
1 you will need a grid tie inverter that's for sure. They're top dollar. As for permits Heck we don't even know what country you're in let along your state :)

2 Sure that will give you the average but if you're trying to replace it with solar you need to know your peak more so than average.

3. 94.4% on on the converter below

4.Voltage from the solar panel is going to go into a voltage regulator it will be the same.

5.so i guess your from ohio? haha
