TTB_SolarEnergy
The macro TTB_SolarEnergy calculates:
- solar power
- cumulated solar energy
- cumulated CO2 savings
- Calculated electric energy consumed by the solar pump
To calculate the solar power, we have the following options:
- Calculation using a flow signal and the temperature difference (”SolarFlow” <>999)
The flow signal can be connected form any:
- external flow meter no matter if it comes from physical connection, a pulse meter using TTA_PulseCounter, M-Bus, Modbus or other meters connected to the supported buses.
- the pump flow at nominal capacity (PMP-07) ignoring the differential pressure influence
- Calculation using external heat power or energy meters (”SolarFlow” = 999)
- These meters can be connected to M-Bus, Modbus or external pulse meters – using the macro TTA_PulseCounter.
Any heat energy meter has a heat power signal. When using a pulse meter with the macro “TTA_PulseCounter” connect the heat power to the output “MomentaryUse”,
The external heat meters can be of two types:
- meters suitable for solar installations and considering the low heat capacity of the water-glycol solar fluid
- In this case, you do not need this macro and can connect the values directly to the solar panel macro.
- meters for water, which do not consider the lower heat power due to the lower heat capacity of the solar fluid.
- In this case you need the macro to apply correction factors to the power and energy values.
