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

The site you need to visit is
The reference section has all the formulas you are looking for and there is a list of dealers by state, plus various state rebate information.
Yes, you can hook up different panels to the same system. There are special controllers that regulate the voltage. I’m more of a hands on nuts and bolts guy so I can’t help you with the formulas and engineering explanations.
Another great place to get information is Home Power Magazine. You can get the issues online or in print. Thanks for going solar!
