Photovoltaic panel overhead installation drawings

How do I design a photovoltaic and solar hot water system?

Provide an architectural drawing and riser diagram for the homeowner showing the planned location for future photovoltaic and solar hot water system components. Space requirements and layout for photovoltaic and solar water heating system components should be taken into account early in the design process.

Should a general contractor install a solar PV system?

A general contractor may face a choice between using an electrical subcontractor or a solar subcontractor to install the PV system. A good solar contractor will have the expertise in solar PV systems plus qualified electricians on staff.

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 a PV system be installed on a roof?

Nevertheless, it is possible to install PV modules on all roof types. If the roof will need replacing within 5 to 10 years, it should be replaced at the time the PV system is installed to avoid the cost of removing and reinstalling the PV system.

How should a PV system be designed & installed?

From the outset, the designer and installer of a PV system must consider the potential hazards carefully, and systematically devise methods to minimise the risks. This will include both mitigating potential hazards present during and after the installation phase.

How much weight does a PV system add to a roof?

A conventional PV system that includes racking materials will add approximately 6 pounds per square foot of dead load to the roof or structure, though actual weights can vary for different types of systems. Wind will add live loads; the magnitude of live loads will depend on the geographic region and the final PV system.
