Grazie Scresan in conclusione tu non li monteresti su stringhe al sole senza ombre vicine? Dal loro sito ero convinto che ci fosse comunque un miglioramento. Ho un impianto da 20kw installato in provincia di Asti , l'impianto è speculare con 2 inverter trifase da 10kw. I 10kwh sulla pensilina ad est producono + kwh della sezione ad ovest , una mia spiegazione è che la sezione ad est ha meno perdite perchè al mattino la T ambiente è più bassa. Ho l'abitudine di fare sempre stringhe lunghe nei miei progetti e quelli della Tigo dicono che su stringhe lunghe le nuvole passeggere fanno perdere ... Nei loro case study hanno in Centro Italia un grosso impianto a terra ...

The Solution
Tigo Energy optimizers were installed on the weaker
array in the hopes of evening its performance with the
stronger one.
The Results—8% performance increase
After retrofitting array “A” with Tigo Energy optimizers,
its performance increased by 8% and increased ROI by
approximately 30%. Not only did the array catch up
with “B”, it actually performed a full 2% better than
array B.
After five months Mr. Z. decided he wanted to benefit
from the improvement of Tigo Energy optimizers on his
full array. Once it was optimized by Tigo, Array B was
once again able to outperform array A giving the
system owner an overall performance increase of 12%.
Customer Testimony
“I was hoping the array would perform better, but I
never expected it to perform that well.”

Tigo Energy Installed on Blue Array
Summary
This installation provided an ideal case for a side-by-side test to demonstrate the benefits of using Tigo Energy. The system included
two arrays with identical modules and inverters, installed in the same orientation on the same flat commercial roof. Neither array
was shaded. The side by side comparison with
