Abstract: Methods and apparatus for assembling solar canopy subassemblies, and solar canopies formed with such solar canopy subassemblies, are provided. The provided method and solar canopy assembly tooling permit solar canopies to be erected quickly and in a highly efficient and cost-effective manner with high quality solar canopy subassemblies, while simultaneously minimizing hazards to solar canopy erection workers by minimizing the amount of time workers must spend at elevated heights and minimizing the number of workers that may be exposed to hazards of associated with elevated work.

Abstract: Cylindrical dispenser (51) is attached in-line to a hose so as to add dispersible solids (89) in the form of granules or cartridges, eg of fertiliser, to liquid, eg water, flowing (75) though the hose. A proportion of the flow passing through conduit (85) (which has holes, slots, or is fibrous) enters surrounding compartment (87) and leaves it again to form part of flow (75) carrying with it dissolved, suspended, etc, fertiliser absorbed during its passage through compartment (87).
