[RE-wrenches] Tigo to go?

[Bill Brooks]

Marco,

 

The only argument you can make for a system like yours is to say that if the
modules degrade at different rates, then the Tigo optimizers make sense.
Otherwise, I can't see how it could be anything but a slight loss. Tough
call for $15k. Other attributes like monitoring and shutting off for
firefighters can help sweeten the deal.

 

Bill.

What's the feedback on these Tigo buggers?  I'm not talking about sites
where shading is an issue, but a nice big commercial roof with no shading.

 

Specifically, I'm talking about a 400-module system feeding into a single PV
Powered 100 kW inverter.

 

Anyone have an opinion whether spending another $15,000 on gobs of little
tiny Tigos would be worth it as far as increased kWhs production?

 

Obviously it's in Tigo's interest to say emphatically yes.  But I is
wonderin'.
