Solar output (1 Viewer)

[Guigsy]

I'm sure many are aware, but your whole panel output is dragged down to whatever the dullest patch of the panel is seeing. If only a tiny corner of the panel is shaded, you'll get terrible output. That could just be the shadow from your aerial or an overhead power cable.

For reference, this is a Victron 175w panel with a Victron Smart Solar MPPT charger. The battery is lithium, about 80% full and accepting full charge.

Same as solar panels at home you need a optimiser for the string panels such as Tigo which could be usefull if you have more than one panel on your MoHo. But you also need the TAP and CCA to moniter as well

Room for another 4/5 panels on there

Room for another 4/5 panels on there

I wanted to put another identical 175w on there. But where the aerial is mounted and where the hole for the solar is, it's about 5cm too short. Doesn't fit lengthways either.

Just a thought, if you used some 10cm right angle ally on the ends of the panel, and some along the long edge, with the van to panel frame under the panel ends, rather than to outside? Trickier, but might allow that second panel to be the same as the one you already have.

It would probably fit. The fact that they are different would irritate the hell out of my OCD though!

I didn't know that - useful info especially if you need to move a metre for full sun

Many also think that you will receive in power the wattage stated on the panel, this is not the case. This would need to be in perfect conditions...sun at 90 degrees to the panel, panel unshaded and totally clean. You will get a decent output but now what is stated. My 230w for instance on a UK bright (but not sunny) day, will only output around 1Ah out of a theoretical (approx) 19Ah. When it is raining they are paperweights.

Last summer in the UK I saw 97 watts from a single Victron 100 watt panel and just under 7amps.

Later in the day, just dropped from 90 watts to 13 watts.

How would this affect ocd? only 1 tilts 3 different sizes and wasted space.
