Oolu's Family's Kit

Like the MTN Lumos solar kits, Oolu's kits great attraction is the investment plan that allows the user to spread his investment monthly or yearly. But unlike other central inverters, it is not able to perform very sophisticated functions and cannot power a wide range of appliances. Also, it can only be charged from the single solar panel.


Even though Oolu guarantees that its solar panels works well during cloudy days, concerns for for those who live in places and periods of the year when the sun does not shine daily still remains.


As a portable inverter, it cannot be upgraded with the incorporation of extra parts.


MTN and Lumos Offers Two New Home Solar Systems


Oolu is a relatively new entry into the Nigerian market and the brand is not yet well known among users. In any case, Oolu targets low-income earners mostly in peri-urban and off-grid rural communities. To connect these remote communities, Oolu has agent networks in the places where it operates. Its agents are full-time employees who also provide after-sales support to its consumers given their proximity to them. Their agents can quickly visit a consumer’s home when the need arises reducing abandonment of failed solar systems.


Oolu says it hopes to reach 1 million Nigerian households and businesses within the next three years.


As always, for urban users in Lagos and throughout Nigeria, SolarKobo can recommend and design more reliable solar-battery-inverter systems that can be procured at a similar cumulative cost of Oolu's kit or even less with the help of an initial down-payment and a post-installation plan that can be spread over a period reaching up to twelve months.
