Sounds like you are making a good argument for microinverters. We've already had that warranty discussion, but if module mismatch is an expensive and difficult to manage module warranty issue, microinverters allow you to, a) not replace a bad module, or b) replace it with a different module if physical size permits.
All I am saying is that warranty becomes less of an issue as equipment prices drop. When my DVD player cost $500 I wanted a warranty. When it cost $29, not so much.

Still, call-back costs and finding same-size, same-spec replacement modules costs do matter. Factor in travel time, labor, troubleshooting, finding replacement modules, paperwork, phone calls, etc. to replace 200-watt modules that cost less than $400? Not to mention how selling bad products and buying from unreliable suppliers affect your reputation. How many spare modules and inverters can a contractor afford to stock? The risk is always there because even reputable manufacturers make bad modules. The pile of bad modules made by reputable companies keeps growing. Europeans have recently recycled 600 tonnes of solar modules plus thousands of dead inverters. See http://www.waste-management-world.com/index/display/article-display/2373 267650/articles/waste-management-world/opinion/2011/08/Solar_PV_Recyclin g_-_One_Step_Ahead_.html <http://www.waste-management-world.com/index/display/article-display/237 3267650/articles/waste-management-world/opinion/2011/08/Solar_PV_Recycli ng_-_One_Step_Ahead_.html> 600 tonnes at 40 lbs/module = approx 33,000 modules at 150 watts = approx 5 MW. 5 MW sounds like a lot but is only 0.03% of the 16 GW installed PV in Europe. Are wrenches seeing less than 0.03% of the modules they install ending up in the trash or sent back to the manufacturer? Yes, Astropower made a good module. Some good people use to work there.

At well under $2/watt, does it matter much anymore? Is there really that much risk of product or performance failure with most reputable manufacturers? Yes, I paid $10+/w for Astropower modules over a decade ago, and warranty definitely mattered at that time. Anyway... sad to see them go. We were a big fan for a while.

Done in by plummeting module pricing no doubt. I'm sure you all are getting the same kind of solicitation emails that I get from mod manufacturers and wholesalers from across the globe peddling mods at low, low prices, including Evergreen. Anyone have any idea what's going to happen to the warranty coverage for Evergreen mods? Will they become unwanted, unwarrantied orphans, a la Astropower? Sad, sad.... marco I'd beware of newer companies offering say, 50 year warranties ! Hopefully NOT the new business model ! boB ________________________________ _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
