It was launched in 2016
Kayoola, which is produced by Kiira Motors, is solar-powered by panels on the roof which charge its two batteries. The batteries increase the electric bus' range by 80km.
The 35-seat bus will operate in urban areas (Kampala-Entebbe and Kampala-Mukono) because of the limitations on how far it can travel.
Kiira Motors' executive chairperson told local media that production is ongoing at a facility in Luweero.
Tickodri Togboa added that the company will contribute 15% of production at a factory in Jinja and 85% will be outsourced from small and medium-sized industries in Uganda.
Kayoola, which is described as Africa's first solar electric bus by its manufacturers, was launched in 2016 by Uganda's President Kaguta Museveni.
How much will it cost?
During its launch in 2016, officials at Kiira Motors said each bus would cost up to UGX220m (about $58,000) if mass produced.
The assembly plant is expected to have an installed capacity of 5,000 vehicles annually -- ranging from pick-ups, buses, light and medium duty trucks
They also predicted that more than 7,000 people could be directly and indirectly employed in the making of the Kayoola.
