Thanks for the links Marty. I have read the reviews and they were helpful. Seems like both panels are similarly efficient.
The quotes (pre-tax incentives) are from 2 different companies.
$26,500: 7 kW system with Sunpower A series 415 w panels (17)
$20,000: 7 kW system with REC alpha 370 w panels (19) and SolarEdge Inverter and Power optimizers
$20,500: 7 kW system with REC alpha 370 w panels (19) with Enphase iQ7 microinverters
Are SunPower panels that much better to warrant a $6,000 price premium or am I mostly paying for the name?
Would you recommend the microinverter setup or power optimizers? Depending on the source, I’ve heard they are basically equivalent, to microinverters are better in partial shade, to power optimizers are more efficient. We have a large tree in the south that blocks some of the morning sun.
