What would your site save with solar instead of diesel?

Enter what you spend today. We show a first estimate of your annual saving under an FBE Energy-as-a-Service contract, and the diesel and CO₂ you would stop burning. Takes 30 seconds; no email needed.

Not sure of litres? A generator burns about 0.28 L per kWh — so 500 kVA running 10 hours at 60% load is roughly 850 L/day.

Turn this into a real proposal — free audit

Estimate only. Your fee is fixed after a metered energy audit and set 20–30% below your verified diesel + grid spend. CO₂ at 2.68 kg per litre of diesel.

How the number is built

Simple, transparent arithmetic.

1. Your spend today

Diesel litres × price × operating days, plus grid bills and generator maintenance.

2. Your FBE fee

Set at 70–80% of that spend — so you save 20–30% from month one, with no equipment to buy.

3. Diesel and CO₂

Every litre you no longer burn is 2.68 kg of CO₂ avoided. Most sites eliminate diesel entirely.
