This Digest gives guidance on installing and using photovoltaic systems on roofs. The guidance refers only to the mechanical installation of roof mounted integrated and stand-off photovoltaic systems; it provides best
practice guidance on installation requirements and does not constitute fixing instructions.

A classification system for photovoltaic systems is included, which incorporates illustrations of commercially available systems. Care, maintenance and inspection are also covered.

This Digest has been prepared as part of a Partners in Innovation project funded by the Department of Trade and Industry. 6 pages.
