Toyota is at the verge of bringing out a hybrid car with solar roofs to power up the car electrically without the use of fossil fuels. The solar cells, manufactured by Sharp, are just 0.03mm thick, but produce around 860 watts of power which can power up the car while it’s being driven. The car might be test ran on public roads later this month.

This isn’t the first time Toyota has made solar panels available for its cars. Way back in 2010 the manufacturer sold panels that could be used to recharge the car’s auxiliary battery. The difference here is that the new panels are much more efficient. They’re capable of producing almost five times as much power as the previous model, and can give over seven times the amount of range.

Toyota has previously justified its decision to focus on hybrids by saying that if it uses its battery production capacity to produce a larger amount of hybrids, then it will reduce carbon emissions more than if it produced a smaller amount of pure electric vehicles.

However, last month it announced plans to produce an all-electric drivetrain platform in partnership with Subaru, indicating that an all-electric Toyota could arrive eventually.

Considering the relatively minor power output you can get from putting solar panels on the roof of a car compared to the roof of a building, not to mention the challenges of doing so, it’s not surprising that the idea hasn’t really taken off yet. But there are a few companies experimenting with it.

Most notably, the startup Lightyear plans to start delivering its “solar car” to customers in 2021, and Hyundai also announced plans to start installing solar roofs on select cars last year.

This could lead to the end of petrol driven cars in all the world and the beginning of the electricity era.
