What is Solar ESP?
Solar ESP stands for Extra Sensory Power. It is the comedy idea that a solar salesman can walk up to a home, squint at the meter, listen to the hum of the neighborhood, and make an outrageous guess about the electric bill.
In reality, good solar work is not based on psychic powers. It is based on utility bills, roof space, electrical panels, battery needs, shade, permits, inspections, and honest math.
But comedy helps explain the pain. Especially when the utility bill arrives looking like it just bought a yacht.
