Giuliano digilio the prosperous future and business opportunities for electrical contractors

  1. 1. UK Solar PV Conference The Prosperous Future and Business Opportunities for Electrical Contractors Giuliano Digilio ECA Head of Technical Services London – 22 June 2010
  2. 2. About the ECA •  The UK’s leading trade association representing the interests of electrotechnical contractors •  Formed in 1901, the ECA has over 3,000 member companies •  Collectively, ECA member companies: •  Generate an annual turnover of £5.5 billion •  Employ some 30,000 people and support 8,000 apprentices in training •  Undertake the greater part of all the recorded electrical installation work in the UK.
  3. 3. Scope of Presentation • Electrical contractors’ perspective, challenges and opportunities • Promotion of new PV technology • Planning issues • Design issues • Installation issues • Inspection, testing and commissioning • Training and up-skilling • Technical support and guidance
  4. 4. Photovoltaics create many Challenges & Opportunities The electrical contractor has been blessed with a flood of new technology which introduces challenges and opportunities. One of these new technologies is photovoltaic systems.
  5. 5. What is a Solar PV System? •  Solar PV systems convert light energy into renewable electricity. •  The electricity generated is fed straight into the electrical installation of the building and is used to power electrical services and appliances. •  Solar PV systems should not be confused with solar hot water (or solar thermal) systems which provide hot water.
  6. 6. Benefits to Clients • Climate change / sustainable agendas • Renewable energy • Legislation • Planning pressures • Available grants • Feed-in tariffs • Energy cost savings • Pay-back is improving
  7. 7. There are many good reasons why electrical contractors should promote the use of solar PV systems: •  Easily fitted to most buildings – retrofit or new build •  Reliable and practically maintenance-free •  PV modules typically offer a 25-year performance warranty (life expectancy is 50 years) •  Clients benefit from generous capital grants •  Clients benefit from cheaper energy costs •  Meets climate change and sustainability agendas
  8. 8. Promotion of PV Technology • Electrical contractors must better promote their skills and services •  Understand the technology •  Core skills for electrical installations •  Training and up-skilling •  Guidance and technical support •  Marketing skills and support
  9. 9. Design Team Member Early involvement of the electrical contractor and better coordination of sub-contractors is essential to ensure good compliant installations.
  10. 10. Planning Issues • Planning application • National Building Regulations • EU legislation/directives • Liaise with Building Control and Fire Officer • Health and safety risk assessment (CDM & FSO in UK) • Utility requirements • Available grant / funding • Type of system connection
  11. 11. Design Issues • Competent designer (electrical engineer) • Interface with architect and structural engineer • Orientation, pitch, shading and space planning • Designer’s risk assessment • System sizing • Grid connected / off-grid system • Feed-in tariff • Structural support / fixing system • National standards and legislation • Switchgear • Lightning protection
  12. 12. Installation Issues • Competent operatives/management • Installation programme • Interface with main contractor • Early builder’s work information • Sub-contract package interface • Site-based risk assessment • Damage, protection and theft • Lightning protection and earthing • Grid connection and interface with utility company • National standards and legislation • Inspection, testing and commissioning
  13. 13. Commissioning • All electrical installations including PV systems should be inspected, tested and commissioned by a competent person and the relative certification/documentation should be issued in accordance with national standards and legislation. • Operation and maintenance documentation must be provided by the installer for the person that ordered the work.
  14. 14. National Standards and Legislation BS 7671 Wiring Regulations Building Regulations Industry Guide
  15. 15. Conclusion • Electrical contractors do have the core skills, but they will need to up-skill and include PV system solutions within their scope in the future. • Electrical contractors will need technical support and guidance from the PV equipment manufacturers, suppliers and their association. •  If electrical contractors do not embrace the opportunities offered to them by PV systems and other new technologies in the future, others will. • Early involvement and good coordination is essential.
