Most households and businesses badly underestimate what power actually costs them, because the spend is scattered across bills, fuel, maintenance and downtime.
Add up the hidden line items
- Your electricity bill (and any estimated-billing overpayment).
- Petrol or diesel for the generator, at today's prices.
- Servicing, oil, parts and the occasional rewind or replacement.
- The cost of downtime — lost work, spoiled food, unhappy customers.
The number surprises people
When you total a year of fuel and maintenance, most homes running a generator daily are spending far more than they think — often enough to have financed a solar system that would have paid for itself.
Solar converts that unpredictable, rising spend into a fixed, falling one.
