Solar didn't quite handle the A/C during June

The numbers are in for my electric bill for the last three and 1/2 weeks of June and the first 1/2 week of July, and my solar system didn't quite generate enough energy to cover my usage. The total excess energy was reduced by 29 Kwh. In contrast, during the preceding month, when the air conditioner (A/C) wasn't used, the excess energy was increased by 468 Kwh. If this pattern holds for the remaining summer months, I should go into the Fall and Winter with close to enough excess energy to handle the days that are cloudy and snowy. During this past month, I kept the thermostat at 76 degrees during the daytime and off during the night. Last year, before I had the solar system, I kept the thermostat at 80 degrees. The weather during this month was hot with few clouds. I thus generated more energy from the solar system, due to the cloudless days, but the A/C was running more.
