It’s a known issue - the current Dashboard Trending doesn’t include solar contribution - all you are seeing is Total Usage and Total Usage Cost for your chosen billing period. Like this Wishlist Item to show Sense that you want the Dashboard enhanced to show correct results for solar users.
ps: I think this original Trending feature was added mainly to satisfy utilities that are buying Sense-enabled meters, like the Landis & Gyr Revelo. Unfortunately that kind of half-done feature kills the usefulness for solar users (I don’t think Revelo offers a solar option).
