JA Solar Panels - bifacial and low-light

72-Cell Bifacial Mono PERC Double Glass Module - Bifacial Mono PERC Double Glass Module - JA SOLAR

I'm in the UK and have a pair of these panels on my white-roofed RV/Camper/Truck
315w on top face, upto 390w with reflective power good for white roofs like mine (that i freshly painted before install for max shine!)


I got them for many reasons.
1) They were cheap (£0.43/watt $0.55/watt at the 315w rating, ignoring any extra from reflective effect)
2) The physical size was about as big as the space i had
3) I was more bothered about getting some power all the time rather than maximum power
4) They were from a reputable UK shop -BIMBLE

Anyone got any opinions? I'm upgrading the system and cant find a reason not to order 4 or 5 more of these panels....... but may as well be open to suggestions, but those sizes work, absolutely cannot go wider. Its a bad picture but you can maybe see the pair on the front roof section, next pair would be right at the back, next pair vertically on rear, and i can squeeze a single in the middle of the roof.

The VOCs are 48/49v which is within the range of a standard panel so the usual charge controllers can handle it, looks like it's a nice bit of kit.
