[QUOTE="binky, post: 553343, member: 490"] all panels are rated by STC, standard test conditions, it's worth having a look at the Californian state tesing of panels or PTC, which is suppossed to be more 'real world' and usually knokcs 10-20 Watts off a panel , howver 290w on a 420 w panel, that's roughly 30% - drivel! Even my 12 year old panels still hit within a few watts of their peak output from installation on a regaular basis. They might be nearer the mark if you are based in the Shetland Isles.... lots of manufacturers have 'training courses' which are free and mostly sales and marketing. Tigos are enhanced bypass diodes, which all panels have, a completely different kettle of fish to solar edge and microinverters. John is also correct, batteries offer greater financial savings than the solar panels do. Now I'm a bit biased in that I like solar for green credentials, but financially it's expensive to fit compared to batteries alone, plus risks potential roof issues if the fitters are 'not so clever'.
