Abstract: A photovoltaic module generates electrical power when installed on a roof. The module is constructed as a laminated sandwich having a transparent protective upper layer adhered to a photovoltaic layer. The photovoltaic layer is adhered to the top of a rigid layer, preferably formed from a fiber reinforced plastic. A wire support tray assembly is affixed to an edge of the photovoltaic module, the wire support tray assembly includes a base portion and a cover portion. The base portion has at least one base portion flange configured to lock with least one corresponding cover portion flange. The base portion has a longitudinally-extending slot configured to couple with the edge of the photovoltaic module. Preferably the wire tray assembly holds the module wiring and occludes it from view. Preferably, the cover portion is concave to shelter the wiring from inclement weather.

Abstract: A method of impregnating a polymer composition with an active compound or composition using liquid carbon dioxide, in order for the active compound or composition to be later released from the polymer composition gradually over a period of time. The polymer composition may comprise polybutylene succinate and pores and/or cavities into which the active compound or composition can be introduced by the method. The method involves exposing the polymer composition to carbon dioxide and the active compound or composition under increased pressure. The polymer composition may be used to form an article for use in repelling or attracting insects, for example wearable insect repellent articles or lures for insect traps. Polymer compositions suitable for use in the method, and articles comprising said polymer compositions and active compounds or compositions are also described. A method of attracting or repelling insects is also described.
