[RE-wrenches] maximum efficiency module inquiry

[Kirk Herander, VSE]

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.

Hi Keith,

 

A few que[#] stions:

 

(Q1) How much is your client willing to pay for the most efficient module
(module not cell)? 

 

(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.

 

Regards,

 

- Peter

Hello,

 

I have been charged with the task by a corporate client to do diligence in
finding the most efficient PV out there which is commercially available, or
may be available in the next five years. 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.
