Small increase of PR in simulations with power optimizers

[UserPV]

Hi, I've done some simulations involving power optimizers, from Tigo and also Solar Edge. The results in the increase of the performance ratio were small, even in situations of shadowing.

Example of a result (performance ratio): 73.6% (without optimizer), 75.8 (with optimizer Tigo).

Soon,

1 - The use of optimizers is being viable in the market?
2 - When simulating, which parameters should I configure for best results?

And I have tested and followed as an example an example of PV*SOL itself.

Thanks!

Hi João,

what you found it is absolutely right. The use cases where power optimizers really can help to generate significantly more energy are rare. The results you report here are realistic, in general you will have only one or two percent more energy yield. For a conference earlier this year we had a poster contribution that came to the same conclusion:

It is in German, but from the images and figures you will get the point. We compare different shading situations and connection schemes and present the energy surplus that you can excpet from different power optimizing techniques.

Hope that helps, kind regards,

Martin
