Review for Air Wind & Solar LLC
good installer, but grossly overestimated production
Air Wind & Solar did a fine job installing my 5 kW system in Houston. Their representatives were good to work with, and the installation only took 2 days total. My only concern is that they overestimated the energy that my system would produce by a whopping 67%! I questioned why it was so high compared to the NREL estimate for my location, and they said that the NREL estimate was too low. After installation, I quickly determined that there was no way that my system could meet AWS's production estimates, and that the NREL estimate was very accurate. So other than the fact that you can't trust the numbers they give you, AWS was a good installer. I wish I would have bargained them down even more from $2.65/watt.
