Monitoring of peak power value a day generated by solar panel

We are looking for a solution to monitor the peak value during a day of generated power by solar panel and display it on a large digital panel meter. The rated output from a solar panel is 0 to 24V and 0 to 8A DC.

We propose a combination of using the following signal transmitters. (Figure 1)

2 pcs.	Signal Transmitters (model: M6DVS)
1 pc.	Math Function Module (model: M6DXF2)
1 pc.	Peak-hold Function Module (model: M6DXF3)

The M6DVS units to select 1 to 5V DC output for the measured values of 0 to 24V DC and 0 to 50mV DC (converted 0 to 8A by a shunt resistor). The M6DXF2 is used to multiply two input signals from them, and its output of either 1 to 5V or 4 to 20mA DC is transmitted to the M6DXF3. The peak-hold function of M6DXF3 enables its output of the peak value during a day.
