They have 100W panels for $1.74/watt on their site right now. Assuming a bad area (5 hours direct light/day for 180 "good" days/year) and 20 year life (to 80% of original capacity) then that pannel is about $0.097 per kWH, which is competitive with electricity in most areas. The areas that have lower eletricity rates also typically have more sun, so it may be that we're finally reaching a tipping point in solar power. It doesn't cover the cost of converters, controllers, battery banks, MPPT, trackers, mounts, permits, insurance, etc. But it's a very, very good sign. -Adam On Mon, Nov 16, 2009 at 12:04 PM, Russell McMahon wrote: > Came across this US based solar panel supplier in passing. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
