Solar panels with different VoC and VmP... what happens?

My ''morning'' array is composed of two 315 watt, 72 cell panels with a VoC of ~41 volts. (They are in series though, so the total VoC is ~82 volts) My ''afternoon'' array is composed of three 255 watt panels, 60 cell panels, with a VoC of ~37 volts. (They are also in series though, so this gives a total VoC of ~111 volts.)

VMP, IMP, VOC, ISC questions | DIY Solar Power Forum

Vmp is typically 0.81 to 0.85 of Voc for silicon PV panels so with a 500 vdc max SCC that is about 405-425vdc max Vmp. When full PV power is not required the PV panel voltage will be allowed to rise greater than Vmp, up to Voc maximum which allows unneeded PV power to dissipate in PV panels.

What effect does a panel''s VOC have on its relationship with a

Voc is the open circuit voltage, Vmp is the voltage at max power point at test conditions, but also this voltage is not going to be exactly at Vmp due to not being at test conditions but it will be close and why you want it a bit higher as the MPPT charge controller will

temperature coefficient of Vmp?

Panel specs list Voc and Vmp, and the temperature coefficient of Voc, but not the temperature coefficient of Vmp. Is the temperature coefficient of Vmp something that can be obtained from the Wiley & Sons, 1991), particularly, sec. 23.3 (p. 779 of the 2 ed.). That chap., even though the book is mainly about solar thermal, is probably about

VOC, VMP, LSC, and matching your array to your inverter...

Use VOC to make sure you do not exceed your inverter''s capacity. Panel VOC x number of panels in your string x 1.2 (a rough constant to adjust for cold weather voltage boost) should be less than your inverter''s max DC input voltage rating. Use VMP to make sure you meet your inverter''s MPP startup threshold.

Voltage at the maximum power point

Starting with the IV equation for a solar cell: I = I L-I 0 e V V t. V t = n k T q to simplify the notation in the derivation, where kT/q ~ 0.026 volts and n is the ideality factor. The ideality factor varies with operating point. An initial guess of VMP = 0.9 VOC gives an accurate solution in two iterations. Using Lambert Functions.
