Anything under 10% is normal: weather, a dusty month or a short outage. There is nothing to fix.

How we worked this out
7.6 kW x 1,450 x (1 - 0.005 x 7) = 10,634, rounded to 10,600 kWh (10,600 - 10,350) / 10,600 = 2%

1,450 kWh per kW from Google's Solar API for your roof. 0.5% a year of normal wear.
