Appreciate everyone’s thoughts on three solar quotes

New Solar Install – Help Deciding Between Bids/Companies

Hi all, long time interest in solar and finally getting around to gettingserious about it. It’s crazy how many solar companies there are these days! I’m in CT and over the last year I us9177 kWhr of power. Expecting this to increase a bit as my GF and her son recently moved in with me. All quotes are the cash price before ITC, haven’t decided yet on financing financing and I’m on the fence about the need for/delaying the battery purchase to a later date. I’ve recieved 3 quotes so far:

Quote 1:
Green Power Energy Size: 8.76 kW Year 1 Estimate: 9.265 KW Panels: (24) QCELL BLD-G-10 W-PEAK DUO BLK Inverter: Enphase IQ 8 Plus Microinverter Battery; Enphase IQ-10 Price w/out battery: $31,536 Battery Capacity: 10.5 kWhr (3.8 kWhr continuous) Battery Price: $24,995

Quote 2: Insight Solar Size: 8.4 kW Year 1 Estimate: 9.204 KW Panels: (21) QCELL DUO BLK ML-G-10 +400QPE Inverter: Solar Edge SE7600 Battery: Solar Edge BAT 10K1PS0B-01 Price w/out battery: $25,620 Battery Capacity: 9.7 kWhr (5.0 kWhr continuous) Battery Price: $16000

Quote3: Plug PV Size: 8.4 kW Year 1 Estimate: 8.911 KW Panels: (21) QCELL DUO BLK ML/10 a+ 400 Inverter: Solar Edge 10000H-US Battery: Tesla Powerwall 2 Price w/out battery: $24,360 Battery Capacity: 14.0kWhr (5.0 kWhr continuous) Battery Price: $14,500

Leaning towards Quote 3 at $2.90/watt. Although I’m wondering if all three are a bit undersized..?

Any suggestions or help is appreciated!! Thanks
