Planning around the sun in Boston

Solar panels

At 42.4° N a fixed array facing due south collects the most over a year at a tilt of about 35°. Use the solar panel angle calculator with the coordinates 42.3601°, -71.0589° for the exact optimum, the seasonal optima and the loss from an east or west facing roof.

Buying a flat or a plot

At the December solstice the noon sun in Boston sits 24.2° above the horizon, so every obstacle casts a shadow 2.2 times its own height at midday. Check what stands to the south before you commit: place the building on the map and read the shaded hours for 21 December.

Photography

Golden hour runs 06:31–07:13 in the morning and 15:43–16:25 in the evening today, and the sun sets toward WSW (246°). The golden hour calculator gives the same windows for any date, and the map’s alignment finder shows the days when the setting sun lines up with a street.

More on planning around the sun: which way a house, garden or balcony should face, how long golden hour lasts and why the earliest sunset comes before the shortest day.
