  1. About Romag 1943 Company Formation 1985 Established on Current site

    1989 introduction of glass polycarbonate lamination 1999 First PV Products 2003 Expansion of PV panel Capacity 6MWp 2007 Capacity increase to 34MWp 2011 Acquired by Gentoo Group 2011 Capacity increase to 60MWp • Visionaries in glass since 1943 • High quality PV products manufactured in the UK • Focus on quality, availability and value for money
  2. What is renewable energy? Renewable energy as defined by Wikipedia:

    “Renewable energy is energy generated from natural resources - such as sunlight, wind, rain, tides and geothermal heat which are (renewable) naturally replenished.”
  3. The UK Feed-in Tariff The Government supported Feed-in Tariff is

    an initiative designed to encourage the installation of renewable energy systems. It rewards individuals and organisations that generate electricity from renewable sources. Feed in Tariff payments for PV will be made for at least 20 years from date of installation for electricity generated from solar PV panels. This rate is adjusted annually to allow for inflation (RPI) Savings via three mechanisms: – Generation for 20 years – Export – Electricity Savings
  4. Solar Photovoltaic • Developed for Space Industry • Converts light

    to electricity • Generates energy from a renewable source • No emissions, no moving parts • No batteries • Long warranties • Very low maintenance • Rated by kWp
  5. The Photovoltaic effect • Silicone, wafer, cell • Polycrystalline or

    Monocrystaline • Efficiency How does PV work?
  6. Opportunities from solar PV • Reduce your electricity bills and

    ‘future proof’ against rising prices. • Solar PV has no moving parts and requires very little maintenance. • By exporting to the Grid you get an additional source of guaranteed income. • It can be used very effectively in new builds – doubling up as a building material – an ‘energy roof’ – as well as a source of energy.
  7. What is BIPV BIPV refers to PV that is incorporated

    in to building elements – Replacing conventional roof tiles – Glazing facades – External cladding To create stunning designs which also generate their own energy, reducing the environmental impact of the building.
  8. Whole roof systems Whole or partial roofing systems Can incorporate

    windows and solar thermal to create a ‘total energy’ roof
  9. Facades • Using Standard modules as rainscreens • Issues –

    matching building dimensions and selecting the right modules 17
  10. Solar Canopies & Walkways PV canopies shade the users and

    generate electricity for use in adjacent buildings and also create the “Green” message
