ShadowFlux panels are built to isolate the affected area so the rest keeps producing. On a van roof crowded with a vent, a fan and an aerial, that is the difference between a specification and a result.\u003c\/p\u003e\u003ch3\u003eThe parts are correctly matched\u003c\/h3\u003e\u003cp\u003e400W of panel into a 40A controller rated for 520W at 12V means nothing is clipped, with headroom for a cold bright day when panels briefly exceed their rating.
