Panel degradation is not built into any of the PV models. If you
have access to the TESS Utility library then you could use Type572
(equipment fouling with scheduled cleanings) to degrade the
performance of your PVs over time. If you do not have access to that
component then it would be appropriate to write an equation that
computes a multiplier whose value decreases from 1 over time. The
value would then be multiplied by the output of the PVs over the
course of the simulation.<br>
Kind regards,<br>

<p>Hi,<br>
</p>
<p><br>
</p>
<p>I am using Type94 for my PV panels and was wondering whether
there is a way to incorporate degradation of the panels? At the
moment when I am running my household simulation for over a
year, the values are just replicated. Thanks,<br>
</p>
