Sunpower vs REC solar panels

in your opinion which is a better performer in terms of efficiency, product, performance
SunPower® P-Series: P19-335
or
REC N Peak Series

I would go with the REC N-peak in this situation. The Sunpower P-series are good but they are no way near the performance of the E and X series from Sunpower which both use very high performance N-type IBC cells.
I haven’t done a direct test but the REC N-Peak use N-type silicon and would outperform the P-series in both high temperatures and lower degradation over time.

Thanks heaps for the advice

No problem… Here is some more detailed information.

Hi folks,

Given that it’s 2021 can I please get updates on the same question?

In your opinion which is a better performer in terms of efficiency, product, performance
SunPower® P-Series: P19-410-COM OR REC N-Peak Series (325 W) for a 5 KW system assuming the inverters and everything else the same!

Hi @mmichael

I think it’s still the same answer that Svarky put above. These particular models are still using the same tech.
