  1. Positioning and Installing Solar Panels A Roofer’s Guide to Sustainability YIRTG is pleased to acknowledge that the Roofers Guide to Sustainability Modular Programme was developed as a result of funding provided by CITB ConstructionSkills as part of their long term commitment to training and quality standards in the specialist roofing sector. This support is gratefully appreciated

  2. The Plan • Sign attendance Register • Aims • Presentation • Activity • Review

  3. CourseAims • 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

  7. Microgeneration Certification Scheme • To receive Feed in tariff: - • PV system must be MCS accredited • Electrical system must be installed & commissioned by MCS accredited installer • www.microgenerationcertification.org

  8. Planning Permission

  9. Conservation/Heritage sites • Exceptions exist where the building is listed, or is in World Heritage site or Conservation Area. • 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

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

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

  12. Maintenance • Consider Maintenance of • The Roof • The Panels

  13. Maintenance

  14. 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.

  15. Glossary of Terms Watt A measurement of power, the rate of energy conversion. PV Photovoltaic – a material which generates electricity when exposed to light. Cell A single PV unit. PV Module A series of single cells mounted and connected to form a /Panel single unit. Array A series of PV panels connected together. String The wiring arrangement for an array of PV panels. AC Alternating current – flow direction, changing 50 times per second. DC Direct current – continuously flows in one direction. Inverter Device to convert DC electricity to grid level AC electricity.

  16. Activity Knowledge Test – Check your knowledge
