What it returns here
No two buildings in Barkin Ladi save the same amount. Across every viable roof modelled here, the middle half lands between 3.4 and 15.9 years to pay back, with returns of 5%–31% a year. If you already run a generator, solar starts by replacing the most expensive units you buy, so it pays back fastest; a grid-only building displaces cheaper units and takes longer.
