The 25-page technical resource provides best-practice guidelines for low- and steep-slope roof systems involving adhered or rack-mounted PV system installation. It includes four sections complemented by figures displaying proper photovoltaic installation, helpful references and a topic-specific glossary. The publication is $55 for NRCA members and $110 for nonmembers.
