Solar Energy... Any Local Stories... You Tube Videos

I'm just trying to learn more about this topic - and there are plenty of other videos up on You Tube about it (if you are interested) as well. This isn't meant to be a sales pitch. It is more of a "wow - look what is going on 'out there'"!

I'm also wondering what local folks - those who have been able to invest in solar energy of some sort - have to say about the cost and/or outcomes...

I would love, should I get the chance, to try this out via a relatively small solar (I really caught the garden 'bug') greenhouse.

Thoughts? Ideas? Feedback?

How do we best harness this - in the most effective way - here in the NorthEast?
