[QUOTE="Iceandsolar, post: 546031, member: 36965"] Hi, I live in the south of England and have been getting quotes for Solar panels and battery. No immediate plans for an EV. The panels would be on an east facing roof at approx 35 degrees. Annual usage approx 3500kw. I have 3 quotes that I would welcome opinions on. Is the Tesla powerwall worth the extra cost or are the batteries in the other 2 quotes still effective and reliable? Option 3 does not include birdprotection but the system has an insurance backed guarantee on the panels and battery. Any useful comments would be welcome. Thanks.
