Micro inverters are definately Not a 'cure all'.
They have their place.
They will not work with all manufacturer's modules.
Take an enphase, for example. It will Not work on a GE module. GE modules do not have enough cells.
Micro inverters come in handy where shading is an issue.

be careful. I own and operate a solar contracting business.
I went to school for PV in Florida, and my parents and alot of friends live in Florida. I have researched Florida's rebate program intensely.

Even with all of the rebates and incentives, I highly doubt you are going to see a 'buck a watt' type cost.
That is some very good salesmanship with some 'possibly' questionable math statistics.

My company gives Free installation on any system purchased through us. Even then, after rebates and incentives, our customers will not see a buck a watt cost, and our selling point is $2 - $2.50 a watt less than the average of our competitors.

If you would like me to show you more accurate cost break downs, message me.

I would like to know how the salesman told you to break down your incentives.
