Frequently Asked Questions
How accurate are the electricity tariff rates?
Tariff estimates should be checked against the latest utility schedule, regulator notice, DisCo band, meter class or official bill. Some countries have complex tiered pricing; for billing disputes, always use official statements and the utility or regulator process.
How is solar ROI calculated?
Solar ROI combines the quote, financing, maintenance, replacement, backup and avoided-energy inputs shown in the calculator. Payback is a planning scenario, not a guaranteed return; replace defaults with an installer quote, current tariff or fuel evidence, and the system coverage you can actually expect.
What does PAYGO solar mean?
Pay-As-You-Go (PAYGO) solar spreads a system's cost across a deposit and recurring payments. Ownership, service, repossession and maintenance terms depend on the provider contract. The calculator models the deposit, payment term and share of existing energy spend the kit can realistically replace; it does not compare live provider offers.
Can I trust the generator fuel consumption figures?
Generator fuel use varies by model, age, fuel, loading and maintenance. Use the calculator's selected curve as a planning assumption, then replace it with a manufacturer sheet, measured runtime log or supplier quote before purchasing equipment or budgeting fuel.
Where do the tariff and fuel figures come from, and how current are they?
Each calculator ships with a bundled country dataset last reviewed March 2026, used only as an editable planning default. Electricity tariffs are anchored to the national regulator where one is bound — NERC (Nigeria), EPRA (Kenya), NERSA (South Africa), PURC (Ghana), EWURA (Tanzania) and others; 12 of 54 markets have a bound regulator source and the rest are tracked as known gaps. Fuel, LPG and water prices move faster than any review cycle, so treat every bundled figure as planning-grade and replace it with today's pump price, a recent bill or an installer quote before acting.
Are these tools free?
Core AfroTools energy calculators are free to use. Some save, dashboard or export paths may ask for an account, but the planning workflows should remain usable without sending sensitive bill or equipment details to a server.
