My system is about to exit its 5th year. April 2020's high day is above April 2019's, but below April 2018 and April 2017. March 2020's high beat the March highs from prior years. It's tough to rely on averages around here given that Colorado still receives some snow in March and April. So I don't have clear evidence that the air quality has led to records, but it does seem like my typical sunny day production is certainly doing well relative to prior years, given that I should theoretically be seeing a slight decline year-over-year as the system ages.
