Marco, The only things on a battery-less PV system that carry a warranty are the modules and the inverter. The rest is pretty much on the installer to do a good job. Unless you are using 3C (Cheap Chinese Crap) modules, the probability of a failure is very small. Personally, I use an inverter which not only carries a 10 year warranty but the company will compensate me fairly for service calls where the inverter is at fault. Bob-O

I’d like to know if many, or any, of you all put aside any money to cover your future warranty liabilities. (I don’t.) My belief is that we as an industry—at least as far as the large majority of us who are independent small companies—don’t have a clue when it comes to calculating what our present and future exposure is as far as warranty liability issues. Having gone through the boom and bust of the solar thermal business in CA. in the late 1970s and early 1980s, there were tons and tons of orphan systems that had been supposedly covered by warranties by companies that were long gone. Makes we wonder how close or far we are these days to a similar situation… marco _______________________________________________ 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
