High temperature losses? Discontinued PVL's? First off, the PVL product is all that they produce and still in production today. The truth is that Uni-Solar is the BEST PV solar for high temperature performance that you can buy. Temperature coeff. is only 0.21!! All other PV modules only wish they could keep up. With bypass diodes on every cell, it is the ONLY true shade tolerant PV solar.
As for failure, I only had one framed module fail (5 years ago) and no PVL's. While it is true that a failed PVL presents a replacement problem, swap a 16" roof panel, the durability and performance make it far more desirable for a hot climate. Most installers are not located in hot climates and don't really understand the great importance of a low temperature coefficient and the effect it has over a lifetime. As for cost, they are much less than you have stated. Our retail price is $4.50/watt but you get to deduct the mounting structure cost, do the installation on the roof panels in your shop before being installed by the roofer and have easy wiring under the roof cap. Being a US made product seals the deal for me. I wish the company would have done better financially and taken more of a market share but they seem to have had their reputation tarnished due to baseless rumors. Hmm. BTW, the US-64 was off their site just after they canceled the product. That day for me was as sad as when Ford canceled the Pantera.

The US-64's were on their site for 3+ years after they discontinued them. They don't keep it updated very well. I believe the main reasons the peel and stick were discontinued was high failure rates, high temperature losses (due to very little heat/air dissapation), and the difficulties in removing and replacing bad panels. Cost was also a factor - on the order of $8-10 per watt. ..................................................................................................

They still have them on their web site. http://www.uni-solar.com/uploadedFiles/PVL-136EN%28AA4-3697-04%29.pdf Drake Chamberlin Athens Electric OH License 44810 CO License 3773 NABCEP TM Certified PV Installer Office - 740-448-7328 Mobile - 740-856-9648
