MAXIMUM POWER POINT TECHNOLOGY

The graph below shows how the IV curve of a solar panel changes with varying temperatures.

In partially shaded conditions there can also be multiple peaks in the P-V curve that can confuse an MPPT algorithm. 

Shown in the diagram below is a series string of solar panels.

A corresponding graph below shows lower maximum power points (LMPP) and the greater maxim power point (GMPP) 

that will result in maximum energy transfer. The GP-RVC series has a smart algorithm that will always choose the right 

peak.
