Is the $50 card free or is it "Free"?
What do they mean by "Your Solar Solution". Are they really your solar solution or are they something else? Who knows. Anyway, an underline would do just fine.
Arguably the best one is on the about us page where they claim to have installed 100's of "state of the art systems". 
Recently, a few homeowners asked if the SMA warranty could be extended. 5-year and 10-year extensions are available if purchased within 60 days of installation.
