Happy Solstice – How will your solar electric power systems work on the darkest day of the year?

The darkest day of the year

In the Northern Hemisphere, our winter solstice occurs when the axial tilt of earth is farthest away form the sun.

Designing and sizing an off-grid power system for your shortest day and worst case weather is a best practice to insure reliable power year round.

For this reason, a more efficient solar panel will not save you money on sunshine the way a more efficient car engine will save you money at the gas pump.” So what is the right metric?
