    What the project investment will enable

    OOLU will use the funds from this raise to deploy and install 2,400 Solar Home Systems across Senegal and Mali

    OOLU distribute solar products from selected and reliable suppliers who are Lighting Global Certified. OOLU's current suppliers are Amped Innovation and Greenlight Planet. The entry-level solar home system comes with a 5-10W PV panel, 20-40Wh LiFePO4 battery, 3-4 high efficiency LED lights and 1-2 USB charging ports. Their second system is a larger modular system that includes a 40W (up to 120W) PV panel, 100Wh (up to 180Wh) LiFePO4 battery, 6 high efficiencies LED lights, 2 USB charging ports and a TV.

    Providing families and individuals with access to a TV has multiple impact benefits. Firstly, keeping up to-date with local news and weather forecasts is important to them to better understand any developments that may impact them. Secondly, educational content on TV is typically very accessible for both children and adults, who are able to learn useful topics, such as farming techniques, through engaging story-telling. Furthermore, research has shown that TV shows often inspire viewers to reach higher, driving them to study and work harder. Finally, it provides an opportunity for families and friends to gather around and strengthen important social ties.

    OOLU's payment plans allow customers between 18-24 months to pay back their systems and their flexible nature allows customers to extend this period should they encounter payment difficulties.


    OOLU will deploy 2,400 Solar Home Systems throughout Senegal and Mali where approximately 40% and 75%  of individuals respectively, do not have access to electricity.

    Not only will your investment into this OOLU offer allow them to make 2,400 Solar Home Systems available to off-grid families, but you'll also be helping the company to grow and provide further employment opportunities. For 2021, OOLU plan to expand throughout West and Central Africa which will allow micro-entrepreneurs to develop rural businesses and gain new sources of revenue.
