While I do think of reptiles as 'solar powered', thermoregulation
includes heat that radiates off of other objects, including the
ground (substrate). What you want provide are cooler and warmer spots
within a habitat so the iguana can thermoregulate by moving in and
out of various temperature zones. This is how they do it in the wild
and are very good at keeping within a preferred temperature in this manner.

Research has shown with other lizards that if they are kept right at
the 'preferred temperature', they have a shorter life span than if
allowed to naturally thermoregulate.
