Peter, Keith,
What I / they are interested in is max kwh/day in their climate. I don't know what they are willing to pay or receive for being a beta site, the first step is to see what's out there and what it takes to get it installed if appropriate. This customer is an outside-the-box thinker that doesn't often take no for an answer, and maximum energy harvest will trump the cost. The site is in the Mid-Atlantic U.S. - it is common for temps to be in the upper 90's with high humidity in summer. Delivery would occur in mid 2011.

(Q2) If they are willing to be a beta site, what would they be willing to do (or agree to let happen) of value in return? (Q3) What is the average high temperature at the site in question for June, July, August and September? (Q4) When would they/you want to take delivery? The real question behind Q3 is "why are they/you focussed on efficiency, and not kWh/kWdc/year or $/kWdc/year or IRR"? Based on where your client is coming from, I may be of help.

They are not satisfied with the roughly 20% efficiency of Sanyo / Sunpower, for instance. They want the greatest power density available and may be willing to serve as a beta test site for something of highest efficiency, and money may not be an object. The roof footprint can accommodate roughly 85KW of Sanyo 210's as it looks today. Any info you folks can provide would be greatly appreciated. I basically need to write a white paper describing everything out there and the pros and cons of each. It is possible I could hire a consultant (recommended by or from our wrench list) to do this research for me if it feels right. I imagine this type of analysis has been done before. Thanks in advance. Kirk Herander Vermont Solar Engineering 802.863.1202 NABCEP(tm) Certified Solar Installer NYSERDA-eligible Installer VT Solar Incentive Program Partner
