Has anyone installed Solatube type skylights in SIP roof? Also, has anyone ordered panels from Panels USA or Panels Inc in Tacoma?

I don't think it makes a difference from the installation process point of view whether you install solartube through a sip rood, concrete roof or a timber roof. You will loose energy efficiency by cutting holes into your roof - how much is a mathematical equation. Can you live with the energy loss is the other question. There is give and take in all building structures.
