It went well, well above my expectation. To elaborate, the 44 panels were installed so neatly in a single day, then the power cables were connected to the net meter and after the required permits were received (solar city will obtain the necessary permits) the panels were switched on and it started producing power. I must say that initially there were some issues with the inverter, but the solar city proactively called us to fix the issue. Later, Mr. Klein, our solar city representative learnt about the issue, and without any delay he personally stepped in, resolved all the issues with the company tech and took the trouble to personally monitor the functionality of the inverter and it has been running smoothly since then. I am rating the quality with a B because of the initial issues that we had with the inverter. Folks, under the PPA plan if the inverter does not work, the solar panels will not be producing power and most importantly solar city will not be able to bill us. They can bill us only for the power it produces. So keeping the inverter running smoothly is in the best interest of solar city and they monitor it wirelessly everyday. If it stops working they promptly attend to fixing it for no cost to the home owner. Finally, with the compliments of solar city our thermostat was replaced with a NEST thermostat and you can learn about its fantastic features on the internet. Remember, all states do not force the power companies to install net meters and in Maryland we are lucky to have net metering and if you are interested in solar panels, my personally recommendation is for you to go with industries leader, SOLAR CITY. The name alone says it all.
