A normal work day, with a looming rainstorm in the forecasts.

The new construction will cause some shading of the solar panels on the main house during the last hours of sunlight in the winter. The loss probably won’t be significant. The power graph below shows from last Wednesday (the 20th) to today (the 26th). You can see the rain-storm over the weekend. But the relevant detail to compare is the tail on the right edge of the power curve: there was no second story until Friday the 22nd. You can see a difference, but it’s slight (of course, the framing doesn’t cast a complete shadow yet either, but the panels are very sensitive to any shading).
