Depending on where you are, $$ seem high, except maybe #3.

Got shade issues that are more than minor ? If not, why micros ?

Any economic considerations on optimum array size ?

Have you run PVWatts for a long term ave. output estimate ?

For newbies, that is the big question to answer. Micro versus string. What is the best value over time with the best performance?

My friend has 24 panels with micro inverters. 22 of those panels died and it was only in service for 2 months. Don't know if it's the panels, micro-inverters or just some software fix needed.

First let me start like this. Tell installer to drop the price to $3.0/watt to go with SMA. If they say no and suggest the price of $3.3/watt for all 3 options . I would go with enphase because the equipment cost is the most, so I do not leave money on the table.

For economic way, the more you get - price of the good and permit, the better.

Lol it is possible the junction box not connect correctly. There is no way 22 out of 24 die in 2 months... Do your friends lie ?

Long time reader, first time post. Looking into a 8.x KW system and got a couple of qoutes.

Any good advice, information, price opinion... Thank you all for the great forum and great information.

My buddy used the same installer I had. His final price for his system was:
27 LG305
27 M250
200A MPU included
For $29,581 b4 tax credit.

newe70, is your installer LA Solargroup http://www.solarreviews.com/installe...group-reviews/? If so with big system around 9k, it could be $3.17/watt like gvl's system http://www.solarpaneltalk.com/showth...ra-Hills/page7

@gvl using LG300 and SolarEdge inverter vs LG305 and M2500. His price was included with the MPU. The MPU is around $2K already. Yes, we both have LA Solar agroupcas out installer.

Do you always need main panel upgrade? Unless you need to move the POCO feed line, the cost should be less than 1000.

I do not need a MPU for my system. It is only at 4.6kW system size. So if I ever wanting to upgrade, I would need to get a 200a box and another inverter or upgrade to a bigger inverter.

Speaking of a MPU from my buddy's system. He has an old electrical box and potentially fire hazard.
