Meet the flexible photovoltaic panel for electric cars


Many companies are studying how to extend the autonomy of electric cars, from the manufacturers themselves, who are committed to improving the aerodynamics of their vehicles thanks to science fiction coefficients, to the battery suppliers (LG and Panasonic mainly), which test with compounds different from the traditional lithium-ion, passing through the tire manufacturers, who try to reduce friction as much as possible without compromising safety.

There are also auxiliary companies that intend to add an extra kWh to the batteries of these cars. This is the case of the German firm OPES Solutions and Fraunhofer Center for Silicon Photovoltaics CSP, which have developed a solar panel that, they say, adapts to the roof of an electric car without any problem and without the need for a radical transformation. They are flexible up to 15 degrees and have been processed to ensure against use to inclement weather (say it is difficult to scratch them ) and they are very resistant to heat generated on sunny days of summer.

Up to 50 kilometers of solar energy

For this reason, they make them suitable for an urban, a compact, or a saloon, in addition to being valid for buses and trucks. The price has not yet been communicated.

These boards have diodes developed expressly for this purpose. Therefore, they have 30% more power per square meter than the current panels that are used today, which also results from inefficiency, which increases by up to 22%. That translates into an extra autonomy of up to 50 kilometers peruse.

Tailored to your car

There are several sizes, the most compact being one square meter, and the largest 3.6 square meters, in any case, without exceeding 2.9 millimeters in height. The appearance of the surface of this plate is reminiscent of carbon fiber. The regeneration power varies between 170 watts and 600 watts, regardless of the season of the year in which we are.

The idea is not new, since Toyota launched it a few months ago in its Prius Plug-in Solar, which is marketed in Spain for about 41,000 euros. This car has 0.1 kWh panels on the roof and they work to store energy to travel one kilometer for every hour the Prius is in the sun.
