Why are solar roadways important?
Designing a solar roadway product that can let light through to the solar cells while also being durable and resistant to damage is a difficult engineering problem. Solar cells are typically covered in glass to protect them from the elements while letting sunlight through, but withstanding the weight of an 18-wheeler with a full load is an entirely different problem. Any solar roadway solution needs to be highly durable to both weight and impacts, which is something that current prototypes have yet to completely solve.

With each year of use, the Wattway Solar Road’s ability to produce electricity has declined rapidly, and at current standing, the road is only producing an approximate 38,000 kilowatts. This is a quarter of what they projected it to produce ( 150,000 kilowatts ).
How long does it take for a solar panel to pay for itself?
If it would take 50 years for a solar panel to pay for itself in electricity, and the lifespan of the solar panel is only 20 years, it is not economically viable. When the numbers are crunched and we take a look at the Solaroad in the Netherlands, which is still more efficient than the Wattway Road, we find that the return on investment would take an insane 1,545 years to pay back.
