New install 58.4KW - Need some advise SolarEdge HD-Wave vs Enphase IQ6+

[hevnbnd]

So no tornado's yet...

Got back two quotes in the 90K range using 3 Phase. Worked out to about $2w. Both pushing cheaper panels. JA Solar 355W Mono 72 Cell and S-Energy 355w Mono 72 Cell. One wanted landscape layout something about they don't get as hot. They have a 10 degree mount. The other portrait. Both producing 57KW and 85MWH annually. So I will have the 30% tax credit and possibly 20K USDA Grant off the 90K eventually.


Thoughts on either brand panel? They said I would be looking at 15K more for LG Panels.

So, $90K- $20K = $70K.

$70K*.70 = $49K approx. installed cost after possible grants and fed. tax credit.

On that subject: If you already know this forget I brought it up, but don't let some peddler B.S. you : The fed. tax credit is 30% and is taken last (AFTER) other credits/rebates/grants, not on the gross price before other credits/rebates/grants, but check w/ your accountant to be sure. There may be some loopholes in USDA grants I'm ignorant about.

$49k/$6k/yr. = ~ 8yr. payback. Could be worse. Could be better. Lots of system prices these days seem to be running about 6 yrs., but that's often in areas w/high electrical costs.

On panel quality: Panels are a pretty much a commodity. Get known panels, and use mfg. prod. literature to get familiar with various panels you do not intend to buy to learn some of what's available rather than relying on vendor pitches. In the end, know that like most decent vehicles these days, panels that are produced in some reasonable quantity and under decent Q.C. measures and procedures will pretty much give long service and will likely be as fit for purpose, producing as much annual output per installed STC watt as most every other panel produced under the same/similar conditions.

Under no circumstances fall for the "most efficient" B.S. from outfits like Sunpower. You will only pay more and get little, if anything, in return.

Landscape orientation running cooler than portrait orientation is a new one on me. I'd need to see data to be convinced either way, but that sounds like B.S. and at best probably and very location and application dependent if measurable at all, which I doubt.

Landscape will allow more shallow row pitch but will require more rows, but that won't affect panel performance due to temp. in any way that can be reliably field measured. That's a layout consideration.

With the Enphase option I would need 177 Panels vs 146 with the LG 400W Panels to reach 58.4 KW. The downside with the SolarEdge is the shorter warranty. If I extend the warranty of all the SolarEdge HD-Wave inverters it is an extra $512 each. This makes the SolarEdge about $4,300 more than the Enphase option. I am not sure if I should even go with the extended warranty with the SolarEdge or not. If SolarEdge is reading these threads. They could loose this sale due to a shorter warranty....

Have you factored in labor costs? As far as I understand, Enphase does not pay contractors for warranty replacement after I believe 2 years. SMA/SolarEdge/Fronius/ABB all pay labor costs. And I have seen far more Enphase go bad than any other manufacturer. That
