Presentation on getting solar PV installed on your farm

1. Solar photovoltaic systemsEngineering, wiring & grid connection

2. PV array options Siting & design considerations Component selection Grid connection MCS & installer selection

4. Installations on houses, schools, offices, community centres, churches, village halls, libraries, museums, farms, railway stations and more. Sundogs (or parhelia) are brilliant spots of light sometimes seen around a solar halo

5. Sundog Energy current live projects Kings Cross Station Client – Kier / Network Rail Project size – 240kWp / £1.3M Technology – Bespoke PV glazing Ferrier Point Client – Rydon / Newham Council Project size – 50kWp / £200K Technology – PV facade

8. Inverter – converts DC to AC

9. Connected to Fuse Box / Distribution Board

11. Comprise standard framed modules, fixed to a mounting assembly just above the existing roof.

13. Various products available Selection depends on tile type and the visual effect desired. Small format PV tiles are typically more costly than larger format solutions

14. Typically installed on new roofs or as part of re-roofing schemes.

16. Ballasted systems are the simplest (rely on the weight of the ballast to resist wind loads); require no roof penetrations; simple to move for any subsequent roofing works.

17. Fixed frames are typically new build / re-roofing solution

19. Cell layout, cell spacing, single / double glazing and desired light transmission all variable

20. As a bespoke product is a more expensive option - typically of interest for commercial or high value projects

22. Often use bespoke modules or laminates, but standard modules can be used in some circumstances

23. Wind loading issues to be considered on large facades

25. Ground mounting often very cost effective & practical option

26. Structures such as pergolas, shelters and canopies can be created or adapted to take PV

27. Tracking devices can boost performance by 20% or more

28. Siting considerations Orientation and pitch Ideal site is one that faces south with a slope of around 30-40 °. Other orientations and pitches may also be viable with relatively little drop in performance

30. Save approx 0.4 tonnes of CO2 Not a sundog site!

32. Open layout ~ 5acres / MWpSite shape, slope and shade factors all influence capacity

33. System performance modelling Software models such as PVSyst can estimate can estimate likely performance

65. DNO connection process Project planning phase Initial system design – ensuring compliance to standards Information phase ( Information exchange with DNO) System design, protection arrangements, peak and fault current, harmonics, earthing etc. Network issues Design phase (Formal submission of design to DNO) Where new infrastructure required >>> DNO prepares connection design and issues a connection offer Construction phase Construction of plant. Installation of grid connection infrastructure (DNO and/or ICP) Testing and commissioning phase G59/2 commissioning (witnessed?).

66. “to evaluate microgeneration products and installers against robust criteria, providing greater protection for consumers”

67. MCS Mark MCS mark owned by UK GovernmentMark licensed to scheme administrator (Gemserve)Mark sub-licensed to Certification bodiesCertification bodies issue mark to product suppliers & installersInstaller provides customer with MCS certificate for systemMCS certificate enables FIT payments Scope: Up to 50kWp (relevant for larger schemes?)

68. MCS – Key PV documents Installer MCS001 Installer certification scheme requirements MCS3002 Rrequirements for contractors undertaking the supply, design, installation, set to work, commissioning and handover of solar photovoltaic (PV) microgeneration systems Product MCS005Product Certification Scheme Requirements: Solar PV MCS011 Test and acceptance criteria MCS010 Generic Factory Production Control (FPC) requirements.
