Almost all the current photovoltaic and photothermal experiments involve with usage of solar simulator. Can any one point out the disadvantages of it? For example, unnecessarily heating the sample.
Many thanks,
Zhaoliang
The major disadvantages are:
1) Solar simulators are drive my mathematical models and associated engineering assumptions. Because these assumptions are intended to simplify actual conditions, they introduce uncertainty in the model predictions.
2) The data used in the solar simulations are uncertain and, hence, can introduce variability on the predicted values.
In order to reduce these sources of uncertainty, the solar simulation models have to be validated experimentally.
Hope this answer your question.

Dear Zhaoliang,
In my perception, disadvantages are:
1. Incident radiation of solar simulator light on the solar PV panel has to be ensured as equal to sun radiation for same irradiation level
2. Heat increase due to sun radiation will reduce the total power output of solar Pv. That has to be accounted while designing the solar simulator.
3. Size of solar simulator should large enough to place the solar PV model to test. But size of solar PV model differs with its rating and manufacturer.
Thank you for you reply. I'm now trying to find a replacement of the solar simulator to fix some original disadvantages, for example unavoidable heating effect, unsuitability to very small samples, inhomogeneous irradiation, difficult to adoption of different wavelength light.
Do you think that would be groundbreaking achievement?
