Tank Temperature vs Solar Thermal Heat Gain (5 hour view) 

Red = Tank Top | Blue = Tank Bottom | Cyan = Collector Supply | Green = Combined Collector Return | Orange = East Collector Return |
Yellow = West Collector Return | Lime = Pump Run Time | Black = Outside Air

PV Production (to indicate solar irradiance)

Green = PV Production in Watts
