Here are some of the more interesting FAQs from the website:
How efficient are the ATA-Solar panels?
Answer:
ATA-Solar collects 9% of the available light/energy from the sun, versus about 12% for crystalline panels. However, ATA-Solar picks up three spectrums of light, therefore collecting earlier and later in the day than traditional crystalline panels that only pick up less bandwidth of the sun’s spectrum. Therefore, the daily-generated electricity is higher with ATA-Solar, versus crystalline panels, since it collects for more hours of the day.
Will you sell the Uni-Solar laminate alone, for others to adhere to metal roof panels?
Answer:
No. We are only selling our ATA-Solar system, with the Uni-Solar laminate factory-applied to our metal roof panels.
Can the installer walk on the ATA-Solar?
Answer:
Yes. Walking on the ATA-Solar panels will not harm them.
