Color specification parameters of common photovoltaic panels

What are the parameters of photovoltaic panels (PVPS)?

Parameters of photovoltaic panels (PVPs) is necessary for modeling and analysis of solar power systems. The best and the median values of the main 16 parameters among 1300 PVPs were identified. The results obtained help to quickly and visually assess a given PVP (including a new one) in relation to the existing ones.

What is the optimal band-gap energy for a coloured solar cell?

For most colours, except the darkest ones, the optimal band-gap energy for a theoretically ideal solar cell is between 1.115 eV and 1.135 eV, matching the value for crystalline silicon. The results clarify the link between the solar cell colour and efficiency and establish a reference point and guidelines for optimizing coloured photovoltaics.

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 are the performance standards for terrestrial photovoltaic modules?

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. It applies only to crystalline silicon module types.

Are coloured solar cells suitable for buildings?

For most buildings black surfaces are not desired, and only lighter and coloured solar modules will be considered. Efficient and aesthetically pleasing coloured solar cell modules therefore represent an important contribution towards more widespread use of BIPV in buildings.
