In practice that means MPPT: a PWM controller would waste the headroom. It also means two in series reaches around 59V open-circuit, which suits a 95V controller comfortably and keeps roof cable current low.\u003c\/p\u003e\u003ch3\u003eBifacial, honestly\u003c\/h3\u003e\u003cp\u003eThe rear face only contributes where light can reach it. On Z-brackets above a light-coloured roof you will see a small gain; bonded flat you will see none. Buy it for the N-type cells, the −0.32%\/°C temperature coefficient and the 25-year warranty — the bifacial rear side is a bonus if your mounting happens to suit it.\u003c\/p\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cp\u003e10.3kg each, and 1312 × 765mm is a substantial rectangle — two of these is most of a van roof once you allow for a vent.
