Got some of quotes via EnergySage for installing solar in SW PA (Pittsburgh Area) and would like to know what y’all think. Roof is facing East/West and panels would be on both front/back. Both of them are local companies. Installer 1 seems to be a little newer to the area, but reviews have been very positive. They also offer a production guarantee and are REC pro installers. Both have a 25 year warranty on parts and labor. I have used Installer 2 in the past and they gave us quotes for two different inverter/battery systems with the same panels. I was very happy with them when we used them and know they do good work.
| Field | 1 | 2a | 2b |
|---|---|---|---|
| Panel | REC405AA | REC405AA | REC405AA |
| Count | 45 | 51 | 51 |
| Total Wattage | 18225 kW | 20655 kW | 20655 kW |
| Estimated Production | 21171 kWH | 21591 kWH | |
| Inverter | Enphase IQ8PLUS-72-2-US | 2 x Tesla 1538000-xx-y | SolarEdge 1 x Energy Hub SE10000H-USSNBBL14, 1 x SE5000H-US, 51 x S440 Power Optimizer |
| Battery | FranklinWH aPower | Tesla Powerwall 2 | SolarEdge BAT-10K1PS0B-01 |
| Battery Capacity | 13.6 kWH | 13.5 kWH | 10kWH |
| Battery Continuous power | 5 kW | 5.8 kW | 5 kW |
| Solar Cost | $47,500 | $55,110 | $58,853 |
| Battery Cost | $15,000 | $14,700 | $17,000 |
| System Cost | $62,500 | $69,810 | $75,853 |
| $/W (Solar) | $2.61 | $2.67 | $2.85 |
| $/kWH (Battery) | $1,103 | $1,089 | $1,701 |
Which would you go with? The enphase optimizers offered by Installer 1 seem better all around, and I heard the LiFePO4 batteries are safer than Lithium-Ion. I am not sure how good the Tesla or Solar Edge inverter/batteries compare though.
