I need to simulate a Bi-facial PV system, however I can't select that option, please see screen shot.

I can still select the bi-facial PV module but can not adjust albedo and any other parameters needed for bi-facial modelling.

Any idea what I need to do?

Thanks

Okay I figured out that the module needs to include "bifaciality coefficient" to be able to use this feature. However, can only one albedo be selected for simulation? what equation does Polysun use to estimate yield for bifacial?

Hi Marcus

The description of our bifacial Simulation you will find here: http://www.velasolaris.com/files/solarw ... inal_1.pdf

If you want to use different Albedos, please use several PV Generator fields.

Thanks for the report.

By using the energy boost equation, shouldn't the EB increase with an increase in albedo....

Why isn't the power boost changing from 150 as shown in the attachments? Everything in the system is the same, just a different albedo.

Dear Marcus

You need to click on the Power Boost field to recalculate the value.

I have tried this and it does not recalculate. Is there a setting I need to change?

Please use a Comma not a point to describe the albedo

This did not work either, anyway the language settings is set for English where period is decimal separator.

Is there a support phone number I can call to help trouble shoot this issue? I need to resolve this for my thesis project

Dear Marcus

I cannot reproduce your problem. Please send your .pse to info@velasolaris.com
