Is $37,710 to install an 11.70 kW DC solar system a fair price?
Project Details
We have a completely flat, unobstructed roof in downtown Chicago. My bill per month is anywhere from $150 in the winter to $300 max in the summer for a lot of a/c use. I'm considering paying cash for the solar system. I'm looking for help or comments/watch outs regarding the quote.
