E Tuk Tuk

Product Description

E Tuk Tuk is a 3 or 4-wheeled vehicle that operates solely on solar power. It can travel up to 50 Km/day at a speed of 30 Km/h, with a maximum load of 50 kg. ^{Interview with manufacturer} It can also travel up small inclines at a speed of 20 Km/h. E Tuk Tuk offers the option of using excess electricity from the battery to provide for a home in off-grid rural communities. The needs of a home start at 250 J/day, while storage capacity of the vehicle starts at 1500 J/day under normal sun conditions.
