What is a roof mounted photovoltaic system guidance?

The guidance refers only to the mechanical installation of roof mounted integrated and stand-off photovoltaic systems; it provides best practice guidance on installation requirements and does not constitute fixing instructions.

Can solar wall mounts be used to power grid based systems?

Investigations into solar wall mounts are necessary and continue to help demystify the generation, distribution and usage of the abundant and renewable energy from the sun. The resultant power from wall mounted photovoltaics could be made available to grid based systems from consumer terminals in an integrated and optimized scheme.

Which properties are best suited to wall-mounted solar panels?

Properties that are most suited to wall-mounted solar panels are ones that have large south-facing walls, which aren’t covered by any shade. South-facing panels are exposed to sunlight throughout the day, which is especially handy for wall-mounted solar panels, given their performance is already hindered by their limited angle.

Are solar stack roof mounting systems ul 2703 listed?

Solar Stack Roof mounting systems are UL 2703 listed. Standard for safety UL/ANSI 2703, Mounting Systems, Mounting devices, Clamping/Retention Devices and Ground lugs for use with PV modules. Solar Stack systems have been evaluated for module-to-system bonding and mechanical load to the requirements of UL/ANSI 2703.

What is a PV module?

PV modules are current-limiting devices, which require a non-standard approach when designing fault protection systems, as fuses are not likely to blow under short-circuit conditions. PV systems include d.c. wiring, with which few electrical installers are familiar.

What are the maximum values of a PV module?

The maximum values originate from two PV module ratings – the open-circuit voltage (Voc) and the short-circuit current (Isc) which are obtained from the module manufacturer. The values of Voc and Isc provided by the module manufacturer are those at standard test conditions (stc) – irradiance of 1000 W/m2, air mass 1.5 and cell temperature of 25°C.
