Solar Thermal Real-Time Data
Temperature Graph Explained!
T1 represents the temperature of the 50/50 glycol/water solution that runs from the solar collector panel into the heat exchanger for the storage tank.
T2 represents the temperature of the 50/50 glycol/water solution that is pumped to the solar collector coming from the heat exchanger.
T3 represents the water temperature sensed at top of the hot water storage tank that heated by running glycol/water solution through the heat exchanger.
In most of the cases, T1 will be higher than the T2 since the heat is transferred to the water inside the storage tank which is also represented by the red shaded area between T1 and T2. If it that is not the case and the water inside is warmer than the solution coming from the panel, it will be represented by the blue shaded area where T2 is higher than T1.
The status of the Pump that circulates the glycol/water solution is read at its peak at either ON or OFF in yellow colored line. This is based on 15 degree temperature difference between the collector temperature, which is not shown here, and the storage tank temperature (T3) that is sensed at the differential controller that controls the pump switch.

Energy Graph Explained!
The kWhs bar graph represents the energy that the system is saving by transferring the heat from glycol solution to the potable water inside the storage tank.
The lbs. of Coal and CO2 are the measure of the offset due to the amount of kWhs in energy generated by the solar thermal system.
The miles driven criteria represents the miles an average car would have driven with the amount of energy that the system saved.
