What it returns here
No two buildings in Dutse save the same amount. Across every viable roof modelled here, the middle half lands between 4.1 and 14.9 years to pay back, with returns of 7%–25% 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.

- Beyond the money, the change people notice is that the things they switch off stay on — about 0.5 kWh a day of currently suppressed demand comes back.
Modelled at today's fuel and tariff, against what each building spends on power now. Both have moved upward, which shortens payback.
