Photovoltaic module panel nameplate

What are the nameplate ratings on photovoltaic panels & modules?

The nameplate ratings on photovoltaic (PV) panels and modules summarize safety, performance, and durability specifications. Safety standards include UL1730, UL/IEC61730, and UL7103, a recent standard for building integrated photovoltaics (BIPV). Safety standards ensure that PV modules demonstrate non-hazardous failure modes.

What is a PV module nameplate?

The nameplate is part of the product markings, here the PV module, and typically shows several ratings e.g. Pmax and Isc. Not only to create the nameplate some definitions are needed, but it is also important to be able to verify such parameters.

Does a solar module have a nameplate rating?

Today, most solar modules perform consistent with their nameplate rating under standard test conditions; however, historically there were sometimes slight discrepancies between what a module’s datasheet indicated and actual performance.

What are the safety standards for photovoltaic modules?

Safety standards ensure that PV modules demonstrate non-hazardous failure modes. Performance standards include IEC 61215, which specifies requirements for the design qualification and type approval of terrestrial photovoltaic modules suitable for long-term operation in general open-air climates, as defined in IEC 60721-2-1.

What is module nameplate rating loss?

Module nameplate rating loss accounts for the difference in the stated power of the module from a datasheet compared with how it actually performs at Standard Test Conditions (1000 W/m2 and 25o C). Most modern modules will have datasheets that accurately reflect module operation at STC, so the default value for this loss is 0%.

Which materials should be used to install photovoltaic modules?

JA Solar recommends that when installing modules at the seaside, stainless steel or aluminum materials should be used to contact the photovoltaic modules, and the installation parts should be well protected from corrosion. The tilt angle of the modules is measured between the surface of the modules and a horizontal ground surface.
