Hi, 

Thank you so much for reaching out — I appreciate your question.

In terms of usage and feedback to the grid, it can really vary quite a bit from user to user. Factors like your specific energy consumption patterns, the size and orientation of your system, and how much energy you’re feeding back into the grid all play a role in the overall impact and efficiency.
