[RE-wrenches] Who has the best overall solar racking solution?

[Jason Szumlanski]

If you plan to use Zep, I don't recommend you use microinverters. Module
removal for microinverter replacement is a huge pain. We had a few systems
with M190's on Canadian Solar Zep's and the M190 failures are causing us
nightmares. I guess with the vastly improved failure rate this is less of
an issue, but it's not worth the risk.

On the same note, the leveling feet are completely seized after about two
years, and other signs of corrosion have been seen (although not by me
personally).

I love the Zep concept for it's low profile, and it does look great, but
there are some drawbacks.

O
h yeah - forgetting the special Zep tool on a service call is no fun.
