Solar Energy for Homes, personal experiences

[AeroK]

I'm buying a house in the future maybe late 2015- early 2016 and I'm really looking into solar energy however I have no experience with it and the only information I know is what I get from the internet. I'm living in TX however I'll be moving back to Louisiana to build and I see that LA is currently offering 50% tax credit and the federal credit is 30%. The example the websites are giving is this:

If the system costs: $25,000

50% La. State Tax Credit: $12,500

30% Federal Tax Credit: $7,500

You Pay: $5,000

Does anybody here have experience with solar energy and if so what do you like or not like about it.

Thanks in advance.
