Hi Allan I can appreciate the sensitivity of the data, however, in most trades, there are generalized pre-determined time allocations for activities/tasks. If you have ever looked at any electrical estimation software, for example, it outlines everything in these types of increments and is widely accepted even at the federal level, for government type work, especially under the auspice of change orders. Even our government needed a datum point to begin to have a conversation.
By sharing, we all can improve our operational efficiencies, as it will become more difficult to make income from selling materials, as a percentage of sales, due to the commoditization of our industry. Pretty soon, most major electrical supply houses to Grainger will be stocking panels to BOS. We, as an industry, will be needing to polish our operations and clearly get better at the execution of the installation. If this venue is unsavory for most, I can be contacted off list, as you suggested. ________________________________ From: Allan Sindelar <al...@positiveenergysolar.com> To: RE-wrenches <re-wrenches@lists.re-wrenches.org> Sent: Wednesday, April 8, 2009 7:59:22 AM Subject: Re: [RE-wrenches] Metrics Keith, As this forum is available to the public, are you sure you want to address this issue on list? Maybe better to request replies off-list, with an offer in return to send collated results to those who contribute.

What I am asking, is, what are you using for labor hours, for a vanilla grid tied residential system? (keeping in mind there are variants, but there also are averages) For example, X amount of people, for X amount of hours, to install 1kW of solar = X amount of people hours/per kW. Thanks Keith
