Sun Lizard Solar Air Shifter -- Assessing your building’s suitability

• We recommend that your building be insulated, reasonably well sealed and energy efficient. The reason is that without a means to holding the heat the Sun Lizard provides, energy costs will still be high.

• Solar Access – the PV panel powering the fans require direct sunlight.  You therefore need to locate the PV panel in a place that gets sunlight for as much of the day as possible.  A north facing roof is best so the unit can be laid flat.
  
  
• Roof cavity – having a roof cavity makes the installation easier.  If there is no roof cavity then external ducting and weatherproof covers are required.  This may make the system less effective or more expensive.
