If one panel in a portable, mobile solar panel array is shaded from the sun by even something as minor as a power line, it can take down that entire panel. If the solar panels are not wired in parallel, that one shaded panel can take down the whole array.Having each panel peaked just right becomes critical. In a parallel wiring configuration, each panel contributes its best input to the overall system. In a series wiring, the worst performer acts like a governor on the other panels.With a parallel wiring configuration, shading or a bad connection with one panel will not affect the rest of the panels. Your system will adapt better to changing light conditions and will, in turn, charge faster.Small, permanent installs or mobile solar systems are often used in places where panels might get shaded from time to time.Also, if you wire your panels in series, it is very easy to exceed the safety guidelines of the Apex and cause severe damage to your system, and it may even create a dangerous situation. Inergy solar panels feature intuitive EC8 keyed connectors that can be wired in only the correct way. They simply won’t go together the wrong way, so you can’t damage your panels or your system.
