Certified Fencing for Renewable Energy Sites (REFI) REFI separates practitioners who merely install perimeter barriers from those who understand how electromagnetic fields, grounding systems, and solar array layouts intersect with secure fencing design. The exam digs into geotechnical site analysis and anti-tamper mechanisms specific to renewable installations—skills rarely covered in standard security certifications.
