I am an ex-employee of Sun America: I was a field installer so i got to see how these systems worked for the clients. At first i thought, like every one else, that all the equipment we were doing work on was beneficial but later i found out that none of what they tell you really saves you any money. All of the service calls we got were from angry homeowners who bought the solar panels and were not seeing any energy bill savings after almost a year. That is because the aero seal product doesnt work and neither do the solar panels! I worked for them and saw this everyday. I became friends with many of my coworkers, and they all said the same thing! I was told by them that none of it works. All of what they say is a lie and none of their products work!
