What does Lifetime Energy Value mean?

Lifetime energy value is the estimated dollar value of energy produced, saved, stored, or lost over the operating life of a solar project.

Why calculate lifetime energy value?

Small efficiency differences can look harmless in year one but become meaningful across thousands of battery cycles or decades of solar production. The spreadsheet may be quiet, but compounding knows how to yell eventually.
