we are looking into building a new home, and would REALLY like to do on grid solar power. our area offers net metering, and the lot and home design would work really well for it. and with net metering you don't need batteries, so that's money saved. i was wondering if any one here has ever installed it? they make a new kind (a laminate) that lays between the seems of your metal roof. that's what i really want. on that topic, any one ever installed a standing seam metal roof?
