Aphotovoltaic(PV) module is a packaged; connect assembly of typically 6x10 photovoltaicsolar cells. Photovoltaic modules constitute the photovoltaic array of aphotovoltaic systemthat generates and suppliessolar electricityin commercial and residential applications. Each module is rated by itsDCoutput power under standard test conditions (STC), and typically ranges from 100 to 365Watts (W). Theefficiencyof a module determines the area of a module given the same rated output an 8% efficient 230 W module will have twice the area of a 16% efficient 230 W module. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes an array of photovoltaic modules, aninverter, abattery packfor storage, interconnection wiring, and optionally asolar trackingmechanism.
The majority of modules usecrystalline silicon cells orthin film cell. Cells must also be protected from mechanical damage and moisture. The cells must be connected electrically in series, one to another. Externally, most of photovoltaic modules useMC4 connectorstype to facilitate easy weather proof connections to the rest of the system.
Modules electrical connections are madein seriesto achieve a desired output voltage and/orin parallelto provide a desired current capability. The conducting wires that take the current off the modules may contain silver, copper or other non-magnetic conductive transition metals. Bypassdiodesmay be incorporated or used externally, in case of partial module shading, to maximize the output of module sections still illuminated.
