I saw a thread from penberth dated 1-15-2011. The quote was for 30 Sunpower SRP-230-WHT-U panels and 30 Enphase Energy, M210-84-240-S11/2 micro inverters. The price quote was around $36K installed with the company doing all permitting, labor. etc.
I am currently looking to install the same system except for using the SPR-230-WHT-D. My main reason for going with this panel is the wattage to size. I like the Enphase micro inverters because of its new technology. I'm putting up a 5.99kw AC system on a hip roof so space is limited. The price quoted me was $43K with a quote from another contractor $44.5k. Other quotes were using different manufacture panels which were larger in size (and would require panels on north-facing roof). My question is should there be that big a price difference in todays economy? And is there a better panel with a equal or smaller footprint of value available?
