My other half is not best pleased about the 60Wp of TopRay solar panels that I bought today from Maplin to supplement my little off-grid system that has been struggling to power my SheevaPlug when we've had a run of cloudy days: basically I want to end every day on the controller's green/full indicator unless we've had a couple of really dreadful days.
I now have a little under 200Wp with about 120Wp facing due south and steeply (~70degrees) inclined to optimise winter collection. The 120Wp and my MPPT should really cover the below-5W 'quiet' power consumption of the plug.
I did bargain the manager down to their 'offer' price (it's not currently on offer) which is about 1/3rd off the ticket price, so at a little over £3/Wp they are about the cheapest per Wp that I can lay my hands on and I'm happy with other TopRay/Maplin panels that I have.
I expect to put these new panels away in summer when I have lots of other generation and kids romping on the grass given that they are at ground level and contain glass. And I'll have to move them at least once to mow the grass this week.
I also found evidence of an overheated junction/terminal so I'm probably going to put in some quality rewiring time tomorrow afternoon if possible when I get back from being on a panel discussion where someone has mistaken me for an expert on something! B^>
