Key Considerations for PV installations for London Federation of Housing Coops 10. November 2012 104 London Street, Reading, RG1 4SJ
Contents • Company Background • References / Past Projects • Considerations for Coop’s 2
1.1 Company Background • Specialised solar photovoltaic (PV) installer and project developer based in north Germany, with subsequently opened international branches • Incorporated in 1996 in Germany, followed by Canada and more recently the UK and Denmark • 125 people at our head office in Germany • Completed ~ 1,500 solar installations worldwide (totalling approximately 63MWp)
1.2 S.A.T. UK • UK branch incorporated in early 2011 in Reading, Berkshire • Focused team effort to address public and council tenders with focus on larger roof areas • Latest addition is communal and larger solar park efforts on • Recently completed several projects in UK: • 30kWp Coop in Reading • 12 kWp, 10kWp Schools in Wokingham and Winnersh • 228kWp, Council building in Huntingdon 4
2.1 Asbestos Roof – Orts Road • 29.6kWp system mounted on tilted roofs • Substantial asbestos-handling experience • Housing estate in Reading • Site works duration about 12 days 5
2.2 Flat Roof – Bulmershe & Forest Schools • Forest installed capacity – 11.97kWp • Bulmershe installed capacity – 10.26kWp • Significant H&S considerations – site works only on weekends to prevent danger to children • Project commissioned by Wokingham Borough Council 6
2.3 Industrial Unit – Eastfield House • Installation size about 228kWp consisting of over 1000 x 195Wp Mono modules • Schueco mounting used for mildly pitched roof • Huntingdonshire District Council system owner • Physical installation spanning about 2 weeks 7
3.0 Considerations for Coops • What are the key considerations for a coop? • Planning • Installation • Commissioning • Operation & Maintenance 8
3.1 Planning • Full roof • 372+384=756 panels 9
3.1 Planning • Roof each edge minimum off 1m • 372+384-28x2-13x2=654 panels 10
3.2 Installation • Coop buildings tend to be older • May have intricate structures on flat roofs & may contain asbestos • Several connection points • Full technical assessment for load bearing capacities • H&S regulations during installation crucial • Wind and snow load calculation • Grid connection and metering strategy (for larger coops) + FIT Application date • Installation size and FIT banding 11
3.3 Operation & Maintenance • Solar panels require little maintenance • If there are issues they arise mostly in the first year • Examples are: • inverter failure • generation display synchronisation • G59 Unit in case of installations larger than 50 kWp • Routine checks like comparison of predicted vs real production 12
