While the PV field is a growing and experiencing rapidly advancing technology, the cost per watt is still so high that it is almost not practical for most consumers.
I too feel any and all certifications and licenses that can be obtained are well worth the time and money spent, if, you are better educated, and it leads to employement advancement or new work possibilities.
While getting in at the ground floor is usually the winning advanatge, I still feel PV is 10+ years out from wide scale use.
