How do I put electricity back on the grid?

I am contemplating installing many wind generators on my large flat roof. How would I sell it back to the electric company? and how is it put back on the grid? Obviously into cannot just be connected to thetransformer (diif. voltage/amperage)? How is this done?

At which height should i be seriously concerned about lightning strikes and how to compensate?

I am building a wind turbine and it is on a steel rod and i will be using a metal pole footed in the ground (4ft as per the local frost line) as its structure.
I have been contemplating on if i need to use a grounding rod to ensure that the generator ($300) or my charge controller/battery bank does not get damaged.
This is a completely homemade project and i plan to have it stand 9-10ft in the air, it is not for major power production but rather just an experiment and i will use the power generated to provide power for garden lighting.

There are trees in the vicinity of where i plan to place the turbine.
