It's tempting to put a project for these into my queue:
http://www.scientificsonline.com/amorphous-silicon-solar-panel.htmlI reckon about 60 of these, built into an array, would provide prodigious power and a tax credit- and for not all that much up front.
What made me think of this? A guy I met up in Iceland - one David Lau - is a kind of Renaissance Man. He has a recording studio near Ann Arbor and bought an array for about $50k and will break even on it over about a ten-year period. He got an immediate 20k Federal Tax Credit and also a state credit, then he gets revenue from the sale of power back to the grid. He's got a 600V array.
I reckon, and have known people who've done it, that building an array is not all that difficult. You just series up a bunch of these PV cells on a weatherproofed structure, then mount them and wire them to a buffer and inverter and into your panel. For that last bit I'd use Dave's electrician. All I'd need to do is build the array and probably hire my builder to do the mounting. Okay, we're looking at at least a couple three thou here, but I think it'd pay pretty easily, given the subsidies and credits available. I really love the idea of having home generation capability. My only real question is with regard to failure rates and expected life on the PV cells. I hate heights and don't want to be going up there all the time.
Has anyone taken this on before?
