How Much Can Your Business Save With Solar?
Use our Nigeria-focused solar savings calculator to estimate how much you could save every month and every year by replacing diesel generator costs with solar power. Enter your current energy spend and get an estimate of your potential savings and solar payback.
Pricing assumptions last verified: 2026-08-08. Your actual savings depend on load profile, diesel consumption, grid availability, system design and financing structure.
Your Energy Bill Is More Than Just Diesel
For many Nigerian businesses, the real cost of unreliable power includes diesel, generator servicing, oil, repairs, downtime and the electricity purchased when the grid is available. Solar can reduce the amount of expensive generator runtime your business depends on.
Monthly Savings
See the estimated amount your business could avoid spending on diesel and conventional electricity each month.
Annual Savings
Turn your monthly reduction into a clear annual energy-saving figure for budgeting and investment decisions.
Solar Payback
Compare the estimated system investment with your projected savings to understand your breakeven timeline.
Calculate Your Solar Savings
Enter your current energy costs and let the calculator estimate your potential savings, solar breakeven and long-term financial impact.

How the Solar Savings Calculation Works
Start with your current energy spend
The calculator uses the energy costs you provide as the starting point rather than assuming that every business has the same load.
Estimate the cost solar can replace
The result considers the portion of your current energy use that a correctly designed solar and battery system could offset.
Compare savings against investment
Your projected savings can then be compared with the estimated solar investment to understand the potential payback period.
Turn the estimate into a real system design
For an investment decision, Olasupo Energy can assess your facility's load profile, operating hours and generator usage to produce a project-specific proposal.
What Determines Your Actual Solar Savings?
Diesel consumption
Businesses that currently run generators for long periods generally have more diesel cost available to replace.
Daily operating hours
The longer your facility operates during the day, the more opportunity there is to use solar generation directly.
Battery requirement
Night-time loads and backup requirements affect the battery capacity and therefore the project investment.
Grid availability
A business with unreliable grid power may have a different savings profile from one that already receives stable grid supply.
System sizing
Oversizing can increase upfront cost while undersizing can leave too much diesel consumption behind.
Financing
Upfront purchase, lease and financed structures can produce different monthly cash-flow outcomes even when the underlying energy savings are similar.
