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 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.

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.

What is a photovoltaic module?

A photovoltaic (PV) module is a packaged, and connected photovoltaic solar cells assembled in an array of various sizes. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications.

Why is grounding important for a photovoltaic system?

to Photovoltaic System Design and Installation” (California Energy Commission 2001). Grounding equipment provides a well-defined, low-resistance path from your system to the ground to protect your system from current surges from lightning strikes or equipment malfunctions. Grounding also stabilizes voltages and provides a common reference point.

Can solar panels be mounted on a roof?

Mounting Location – Solar modules are usually mounted on roofs. If roof area is not available, PV modules can be pole-mounted, ground-mounted, wall-mounted or installed as part of a shade structure (refer to the section “System Components/Array Mounting Racks” below). Shading – Photovoltaic arrays are adversely affected by shading.
