When we were configuring ours....almost all facing due West....they offered a deluxe panel that had spirals down all the tubes in the panel. Quicker to heat the water. What sold me was they came with a 10 year warranty. Can you imagine anything sitting in the blazing FL year around and lasting 10 years (actually going on 12 now). I think over the 5th through the 10th year they replaced 5 different panels.....in warranty....$0!
I don't remember the difference in price other than I thought it was reasonable for what was being offered.
And......during the annual maintenance (that I requested)....they offered a one time special to replace all the panels at half price.
I chose to pass betting replacing panels in the future would be less than replacing them all....toss of the coin.
