Solar Panels (PV) and Voltages

Mixing different panels

When connecting in parallel you should keep the panel voltages (VoC, Vmp) the same for optimum results. If you have no choice but to use different voltage panels the blocking diodes become a necessity. When you have more than 2 panels in parallel you should be using a fuse in line with each panel, and optionally a blocking diode. (diysolarforum.com)
