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.)

6 FAQs about [Vmp voc solar Monaco]

What are VOC and VMP in solar panels?

Voc and Vmp are two important specifications when choosing solar panels. Voc is used to determine the maximum voltage rating of the solar charge controller, while Vmp is used to determine the size of the solar panel system needed to meet a specific power requirement. In addition, Voc and Vmp can be used to calculate the efficiency of a solar panel.

What is the difference between VOC and VMP?

VOC will give you information on the number of solar panels you’ll need to power your electronics. Vmp will give you the maximum voltage your solar panels will generate under ideal conditions. Which One is More Important for Solar Panel Voltage? VOC is an ideal number. It is ordinarily never reached during normal operations.

Why is VOC & VMP important?

Here are a few key reasons why Voc and Vmp are of utmost importance: Voc is important because it is used to determine the maximum voltage rating of the solar charge controller. The solar charge controller is a device that protects the battery from overcharging and ensures that the battery is charged at the optimal voltage.

What is the difference between VMP and VDC?

VMP (Maximum Power Point) is approximately 0.52 times VDC (Volts Direct Current) times the number of series connected cells within the solar panel. Actual voltage depends on the current supplied and temperature of the panel. VMP and VDC are not the same as Voc (Open Circuit Voltage) and Isc (Short Circuit Current), respectively. If you go to the Blue Line in your I/V curve--That is V*I of the solar panel output.

Why is VOC important for a solar charge controller?

Voc is important for preventing the solar charge controller from being damaged. If the Voc of the solar panel is higher than the maximum voltage rating of the solar charge controller, the charge controller can be damaged. This can be a costly repair, and it can also leave your solar panel system without power.

When is the best time to measure VOC & VMP?

The best time to measure both is in the morning. For VOC measurement, make sure to disconnect all devices and for VMP measurement, connect all devices. Weather and climate (Cloudy, rainy, foggy, snow, temperature) can play a vital role and give different outputs to your VOC and VMP. Can solar panels exceed VOC? Yes.
