CdTe technology and the CIGS technology in efficiency, and they ae both lumped together as “thin film”. And likewise, there is some separation in the monocrystalline PV market between heterojunction vs other device structures in the temperature coefficients.
My request is to add a 4th module type called “custom”, and if that option is specified then there are two new inputs for module efficiency at STC and temperature coefficient of efficiency. I believe that’s all that you need to specify to model it with the simplified pvwatts equations.
This would allow the model to handle other types of modules that don’t match the three predefined technologies, and would somewhat “future-proof” the model since it’s always possible to override the built-in options as the technology evolves.
A couple points on this:
For the crystalline silicon modules, I suggest updating your options for quality/efficiency of pv module. Currently, the help system identifies the options as:
Consider updating this table to have Standard and Premium modules that are older and newer. Something like the following:
Or add in an option to enter Beta Voc (and NOCT/NMOT) as part of System Information specs.
