Summerfest at AT&T Park!

This year’s event will be at AT&T Park, home of our world champion San Francisco baseball team! With over 2,000 solar professionals expected to attend, this is the perfect venue to unwind from the day or continue business discussions. Summerfest will take place on the same night as the MLB All-Star Game which will be broadcasted live on the jumbotron for all to enjoy. We’ll be offering company sponsored tours of AT&T park, special use of the batting cages, custom photo booth baseball trading cards, hosted food and drink stations, and much more!
