Solar Roadways
(SR) is a modular system of specially engineered solar panels that can be walked and driven upon. Our panels
contain LED lights to create lines and signage without paint. They contain
heating elements to prevent snow and ice accumulation. An LED would be ideal because of its
low power consumption. Solar cells use certain
wavelengths of the light spectrum.
An incandescent bulb produces all the wavelengths the
sun does, but in different
amounts. So, from a scientific
standpoint, LEDs will probably
produce the correct light to charge a solar cell. The Solar Roadway panels
are made of tempered (safety) glass. Glass was chosen for its hardness,
strength, durability, and transmittance.
SR glass is textured to
create proper traction for vehicles and pedestrians. Sebastian Anthony noted in Extreme Tech that the cost
to replace all roads in the United States with Solar Roadways panels would come
to approximately $56 trillion,
based on Scott Brusaw's cost estimate of $10,000 for a 12-by-12-foot (3.7 m × 3.7 m) section.
