West-facing solar panels outearn south-facing arrays in Austin

Original: In Austin, west-facing solar arrays pushed 49 percent more power into the 3 to 7 PM peak window than south facing panels of the same size, and the grid's pricing clock made that the more valuable half of the day

Data from Austin shows west-facing solar arrays delivered 49 percent more electricity than south-facing panels of identical size during the 3 to 7 PM peak demand window. Because grid electricity prices are highest in those late-afternoon hours, the extra output made west-facing installations significantly more valuable, challenging the standard advice that south-facing orientation is always best for rooftop solar.

Why now: The finding challenges conventional solar installation guidance and matters as grids increasingly price power around evening peaks
