Yudelaimys Barrero Muñoz used to spend up to three hours on the side of a highway under the blazing sun waving money at drivers as she attempted to hitch a ride from Cienfuegos, Cuba to Santa Clara, where she buys supplies to resell and support her husband and two children.

The 43-mile (70-kilometre) trip was impossible to make on her husband’s bicycle — at one time the family’s only mode of transportation — and later, with a rechargeable, three-wheeled vehicle whose battery didn’t have the capacity for the round trip.

Then, in early April, a local business owner opened what is believed to be Cuba’s first solar-powered charging station — and it was free. Cubans soon flocked to the solar station — or “solinera” as it’s known in Cuba — recharging everything from electric vehicles to UV nail lamps.
