This support is gratefully appreciated Positioning and Installing Solar Panels

2. The Plan Sign attendance Register Aims Presentation Activity Review

3. Course Aims To raise awareness of conditions required for the installation of solar panels To promote safe working

4. Activity What should be considered to ensure safe working when installing panels

5. Before installing solar collectors on a flat roof consider… The condition of the existing waterproofing Is the roof decking structurally sound Ensure it is safe to carryout the installation How do you intend to lift the solar panels to the roof area safely

6. The Work at Height Regulations 2005 (WAHR) Work at height should be: Properly planned Appropriately supervised Not carried out if weather conditions jeopardise health and safety Those working at height should be: competent or if being trained, supervised by a competent person

In these cases, and particularly if the panels are to be mounted on an elevation visible from the highway, then Planning Consent will be required. In these cases the panels might be mounted on an outbuilding or elevation not visible from the highway but planning permission may still be required

11. Roof Structure Many traditional roofs are already at or near load capacity before installation of panels

12. Roof Condition Roofs should have the same projected lifespan as the panels being installed

13. Maintenance Consider Maintenance of – The Roof – The Panels

14. Maintenance

15. Wind Loading Wind loading should be carefully calculated to ensure the solar installation will be able to maintain the expected loads placed upon it and to ensure the loads are not transferred to the roof covering.

16. WattA measurement of power, the rate of energy conversion. PVPhotovoltaic – a material which generates electricity when exposed to light. CellA single PV unit. PV ModuleA series of single cells mounted and connected to form a /Panelsingle unit. ArrayA series of PV panels connected together. StringThe wiring arrangement for an array of PV panels.
