[RE-wrenches] AC modules verses codes and safety

[penobscotsolar at midmaine.com]

Hi Jeff,
   We were contacted the other day by Lowes, who asked if we would be
interested in installing their (highly overpriced) "plug and play"
systems. They are selling Andalay Solar's 3kw package (they us
Enphase). I told them we would at an installed price much higher than
we usually charge. They agreed on a price. I'd rather do this than have
solar get a bad name with owner installed systems.
   Throughout my 20+ years installing PV, the majority of our service
calls in any year is on owner installed systems. New England in
particular seems to be particularly prone to resident DIY's. With grid
tie, the ante is upped dealing with high voltage ground faults and just
high voltage DC in general.
   I expect these service calls only to grow.

Daryl
