Sorry for the industry jargon, but measuring things in kW won’t give you the full picture, you want to compare things in “kWh”. Your utility bill should show your price in $/kWh and the solar company should have given you a production estimate from Helioscope or some kind of similar energy estimating software that shows expected annual kWh output

Their pricing looks good, you’re getting black on black modules and optimizers for a bit over $2 per watt after incentives. As someone who works in the industry I’d say that’s a pretty decent price.

What have they promised for your annual production estimate? Also what’s your current cost of power?
