[big al]

Hi bigAl here about to change my solar panel I have at the moment 140 watt which was fitted to to the van 18 years ago when van was new was advised to fit new panel so got new one a185 watt as my old panel only brings in 0.32 Watts off power also a new controller off 15 Watts I paid just under £200 for all the part's so when the van was new it cost me £700 to have the lot fitted so for just under £200 and a nice bottle of whisky it's a know brained I will give you the results when fitted cheers Big Al

Did you fit a mppt regulator or a old school pwm which is useless bit of cr-p.

It's not fitted yet and yes I'm putting on a new 15watt controller and it's what you said thanks for that.

Whilst PWM's are certainly not as efficient as an MPPT Trev they certainly aren't useless crap and many people have had good results from them on budget systems.

Agreed. PWM still has a place to play in many budget systems. One of many good internet opinions expressed here;

Hi Al.
I.m just about to replace my 6yr old 100w Solar Panel on my Swift 684 MH & after studying the new technology have opted for a Renogy 200w Shadowflux panel which is to be delivered tomorrow as the reviews are all positive
