September crossed the 3.5 Megawatt-hour production mark to end at 3555 kWh. We are well on our way to the predicted 3.8 Megawatt hours per year predicted by our installer (Mr. Sun Solar). October should perform about the same as March did based on the symmetry we've seen so far (see chart below) and that would get us to the goal.
The Autumnal Equinox occurred on September 22 here in North America and the solar production confirms that the days are getting shorter. Even worse is the oblique angle of the Sun. You can see how the Max kW value is sharply declining.
