Transcript

  • 1. Solarcentury
  • 2. Company Highlights
    • A building integrated solar market leader – a downstream business
    • Unique & Strong in-house R&D & IP , 4% revenue invested
    • +40% annual growth business driven by own product innovation
    • Offices in UK, France, Spain and Italy; 115 employees
    • Manufacturing partnership with Sony UK and Jiawei, China
    • Strong supply chain underpinned by relationships with leading global suppliers
  • 3. The PV project stages Engineering PV Mounting Inverter Installation Development EPC O&M Planning Grid permission FiT provider Finance Operation Maintenance Measurement 1 2 3
  • 4. The PV project stages Engineering PV Mounting Inverter Installation Development EPC O&M Planning Grid permission FiT provider Finance Operation Maintenance Measurement 1 2 3
  • 5. Narrowing choices
    • Objectives: return (how much), CSR, planning, brand, energy security
    • Risk appetite and financial structure: who is going to own the system?
    • Capex and access to debt
    • Opportunity: - land - roofs - new roofs
    • Location: availability of irradiance
    • Yield vs Size of system
    • Timing
    • Hassle factor!
  • 6. Bari, Italy - 1MW ground mounted
  • 7. Hutton Mews, Putney
  • 8.  
  • 9.  
  • 10.  
  • 11. PV Monocrystalline (8m 2 /kWp) (7m 2 /kWp) Polycrystalline Hybrid (6m 2 /kWp ) Amorphous (15-20m 2 /kWp) Cloudy conditions V.large surface areas Small surface areas Good yield Large surface areas Good yield Small surface areas V.good yield
  • 12. Monocrystalline (7m 2 /kWp) Small surface areas Good yield
  • 13. Hybrid (6m 2 /kWp ) Small surface areas V.good yield
  • 14. Amorphous (15-20m 2 /kWp) V.large surface areas
  • 15. (8m 2 /kWp) Polycrystalline Large surface areas Good yield
  • 16. Mounting structures
    • On roof – suitable for high quality roofs, structurally sound that will last for 25 years
    • PV is the roof – suitable for replacing poor quality roofs, for high wind loadings, to max out the roof and ideal for new build
    • Certification is tightening up
  • 17.  
  • 18.  
  • 19. PV is the roof
  • 20. Skylights and vents Comes with skylights and/or roof vents
  • 21. Gutters Gutter brackets fixed to angle-section at 40cm centres. Angle-section fixed to underside of MSR.
  • 22. MP sheets MP Sheet provides protection to the junction box and cabling at the rear of PV module from chemical environments (gases, vapours etc.) or physical protection from activities within the building
  • 23. Integrated insulation
    • T-Profile support rail
    • Locking bracket
    • Insulated panel with Kraft aluminium vapour barrier (80mm – R d 2.25)
    • not shown – additional 100mm of insulation on top to give R d 3.65
    The insulated panels are installed between the I -beams (purlins) of the roof structure : Purlin Density = 3.5 kg/m ²
  • 24. Design and installation
    • MCS
    • Track record
    • Price considerations…
    • … and yield potential expressed as Performance Ratio
    • The effectiveness of the PV system (i.e. how well it is designed and installed) is the ratio between the AC kWh energy delivered compared to the DC kWh potential.
  • 25. PV SYSTEM Modules Inverters Stringing PERFORMANCE RATIO THE measure of PV system effectiveness Available radiation at array: SHADING ORIENTATION INCLINATION YEAR to YEAR variation AC kWh SITE & WEATHER CONSTRAINED
  • 26. Financing options Farmer Developer EPC Investor Utility Farmer Developer EPC O&M O&M Investor owns system £ £££ £££ Farmer owns system
  • 27. Next steps
    • Ground mount? Developer partner: Savills
    • Suitable roof? Please speak to myself or Oliver Sylvester Bradley
