Sungevity vs RGS quotes (String vs Micro inverters) via /r/solar

Hi – I'm looking for some help. I've received a few quotes from providers and have narrowed it down to Sungevity vs RGS with the prices being within $1,000.

What in trying to decide is which is a "better" system for both now and over the long term including maintenance or other issues.

Sungevity: (9.18kw – 1st production of 8,491kwh) – 36 Trina TSM-255PD05.05 modules – Solar Edge SE 7600a string inverter – 10 yr parts on modules 12yr parts inverter 25 year production (.07% degradation)

RGS: (9kw- 1st year production of 8,970kwh) – 30 Silfab SLA-M 300 modules – Enphase m250 micro inverters – 12 year parts on modules and 25 year on inverters warranty 25 year production (.07% degradation )

My house faces NE so sun travels at a 45 degree angle over it. Both designs plan on putting an equal number of pannels on both sides of roof.

My first issue is the production. Sungevity shows a lower 1st year production from a slightly larger system – is this due to the string inverter setup? Would I not produce power when the back side pannels are in shade (later in the day) even if front pannels have sun?

Based on a little research my roof setup seems to be better suited for micro inverters.

My final question is with service response for each company. I've seen good and bad reviews for both (and other companies as well). Anyone here have a better feel for which company will be easier to work with shoos I need warranty issues? Since my state (MA) has a 10 year SREC program any time my system is down is not only costing me money by having to pay for power but Also losing my ability to generate credits.

TLDR: have 2 solar quotes between Subgevity (String) vs RGS (micro). House faces NE and with pannels on both sides of roof which is a better option? Also which company will provide better service after sale.

Thanks!
