Any FG here have experience with solar systems? I found this site http://standard-project.net/solar/hikaku_brands.html with seems to provide cost efficiency info, but first hand experience is always best.
What's the deal, worth it? Wait for efficiency to improve? Short payback, long warranty are top of the requirements of course.
Any insight welcome.
