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.

How should a solar PV system be installed?

Modules and PV systems should be installed by authorized and qualified personnel. Follow all safety precautions of all components used in the system. Long periods of shading on the module's surface from the sun can result in cell power dissipation and overheating. Do not clean the glass surface with chemicals.

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.

How does a photovoltaic system work?

The heart of a photovoltaic system is the solar module. Many photovoltaic cells are wired together by the manufacturer to produce a solar module. When installed at a site, solar modules are wired together in series to form strings. Strings of modules are connected in parallel to form an array.

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.

How do I design a PV battery system?

A PV–battery system must be designed such that the string cable/ string fuse design and specification reflects that fault currents may come either from the array itself, from the battery or from both.
