Solar Panels, Advice?

[Chris1129]

A friend of mine just got solar panels on his house and referred me to the company and sales rep. Solar City is offering to install, maintain, and warranty the system for a 20 year lease period for NO COST to me. They stated that instead of paying PSEG .17-.19 cents currently per kilowatt, I would pay Solar City, .12 cents per kilowatt, with a fixed rate of increase at no more then 3%, vs PSEG's 5-6% rate of increase. Another big advantage is that during the summer, the panels reflect the heat, reducing the cooling needed to cool the house by 1/3. Also in the winter time, the panels act as a blanket and keep the warmth in.

I have a few concerns with not knowing much about the growing company, Solar City, or what negative aspects the solar panels will have on my house, specifically the roof.

Can anyone share any knowledge about Solar Panels, or this company?

Would you do it on your house to save 1/3 on your electric bill?
