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!

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

PV is the roof

Skylights and vents

Comes with skylights and/or roof vents

Gutters

Gutter brackets fixed to angle-section at 40cm

centres.

Angle-section fixed to underside of MSR.

Module ProtectionSheet

MSR

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

Integrated insulation

1. T-Profile support rail2. Locking bracket3. Insulated panel with Kraft aluminium vapour barrier (80mm – Rd 2.25)4. not shown – additional 100mm of insulation on top to give Rd 3.65

The insulated panels are installed between the I-beams (purlins) of the roof structure :

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.
