[RE-wrenches] String Vs Micro

[Keith Cronin]

As I look out on the market place here, it must be close to 100 to 1, micro inverter installations vs string on residential systems.

Don't know what the primary reason is, but I sense simplicity, as there are less "wrenches" out there, so to speak.
The electricians and mechanical type folks I work with seem to get into a groove and just go for it.
Sure, sometimes their biggest challenge seems to be interference due to the communications signals, but that appears to be the only hurdle.

The more companies I work with or talk to, say the additional cost of micros is worth it, as opposed to training someone on string sizing and the concern for DC wiring mistakes.
Perhaps its also due to the fact that we have smaller roofs and the need to be on multiple roofs, where other places around the country can put the system on one roof and be done?

The perception of people that have micros seem to be bullish on the ability to know what is going on and when things are or aren't working and receive status.

Alot of the leasing companies seem to be shying away from micros and perhaps its cost or the future liability of sending wrenches out to swap devices?

What are wrenches seeing elsewhere?
 
Regards, Keith
