Source measuring unit for photovoltaic module


I work for a university in the UK (Heriot-Watt) and we are looking for a source measuring unit capable of measuring IV curves from a 300Wp photovoltaic panel. Of course one of the challenges is finding something within our budget (circa £2000).

Are there memers out there that have tackled this problem and found a cost effective solution?

Thanks in advance!

After some searching, it seems the Seaward IV tracer is the most cost effective solution details of which can be found here. The IV data can be exported to csv file for analysis using Excel which is good. It isn't a programmable unit which isnt ideal.
The National Instruments PXIe-4139 is a programmabale SMU which would suit our technical needs but costs over £4000.

Hi Leonie,
Thanks very much for looking into this. I'll get in touch with the product plus team and see what they say. Many thanks!

Hi there, it's not an engineered solution as such - hoping there may be DesignSparkers out there that have experience with this - but in the meantime, I asked our RS Pro Engineering guys. RS Pro does a 180W photovoltaic meter (123-2205), but as you need 300W, you could contact our Product Plus team who source items we don't have in the range. Just contact and tell them you need the same as 123-2205 but the 218 model (which is the 300W version).
