Frequently Asked Questions

How does the 5-year savings estimate work?

We compare your current diesel + grid token spend (inflating each year at typical Nigerian fuel-price trends) against a Mango PPA rate of ₦180/kWh with a 3% annual escalation cap. The gap between the two, over 5 years, is your projected saving — try the estimator on the homepage or Business page.

What's the difference between Outright Purchase, Rent-to-Own and PPA?

Option A (Outright Purchase) is 100% upfront capital with maximum lifetime savings. Option B (Rent-to-Own) needs a 10–20% deposit with flat monthly installments over 24–36 months and automatic title transfer. Option C (Zero-Upfront PPA) costs ₦0 upfront — you pay only for the solar energy you consume, at a locked-in ₦180/kWh base rate.

What warranty comes with the equipment?

Solar panels carry a 25–30 year linear power output warranty (LONGi Lifecycle Quality). Inverters and smart lithium batteries carry a 5-year full replacement warranty against manufacturing defects.

How long does installation take?

Most residential installs are completed within a week of your site survey. Commercial installations follow a guaranteed timeframe agreed at the ME-SAF-01 site audit stage.

What safety standards do installations follow?

Every Mango installation follows our ME-SAF-01 standard: tested earth pits strictly under 5 Ohms, dedicated heavy-load bypass circuits, and 300mm inverter ventilation clearances — backed by a 4-hour regional field engineer dispatch SLA for critical alerts.

Do you offer wholesale / bulk pricing?

Yes — regional distributors, developers and certified installers can apply for a Bronze, Silver or Gold wholesale partner tier with volume discounts and trade credit terms via our Wholesale Trade Portal.
