    Oh - I forgot another significant item - I have limited roof area - so I bought 280W panels instead of 250/260W. That was $.25/W to $.20/W difference. (I would have needed more racking, etc - but still would have been at least $.15/watt I think)

      I was estimating $2 per watt for DIY.
      Good estimate, that's exactly what my 16 panel Enphase system cost including shipping, sales tax and permit.

        Does that include what you spent on other hardware/tools you needed?
        (ex. roof sealant, shingle ripper, bolts, conduit, breakers, etc.)
        And what wattage panels / how much per watt for the panels? (I paid ~$1/watt just for the panels - I could have paid $1.20/W or $.80/W depending on efficiency of panels )

          Also ordered from Renvu. I did a lot of the install myself but then a licensed electrician/solar install mounted the panels and wired from panels to disconnect. Installed on my pole building and ran about 140 feet of #6 to house with a line side tap. I have 34 260w panels with enphase 215 micros. Cost breakdown below.

          $13700 panlels-racking, nuts, bolts,enphase envoy & cabling
          $1450 mis.- conduit, wiring,disconnects,breakers, trencher rental,etc.
          $100 solar interconnect fee- SCE&G Electric
          $2000 Fee to installer

          $17250 total for 8.84kw system before tax credits $1.95/watt. Final after tax credit will be about $7762.50 $.87/watt
          System went live on 7-23-15 and so far am pleased with the output. Had a high of 52.6kwh on 8-12 and a total of 1.21mwh
