• Dust, dirt and organic matter
mean the roads will need regular
cleaning for the solar cells to remain
efficient. Wear, tear and scratches
will also reduce the amount of light
reaching the cells. And most roads
are lined by large objects like trees,
preventing light from reaching the
surface.
solar panels underneath, reducing
their efficiency.
• The LEDs are unlikely to be visible during the day. What ramifications does this have for warning
systems and lane configurations?
• There is no information available regarding stopping distances
on this new glass surface. Of particular concern is stopping in wet
conditions.
• It is impossible to angle the
solar panels towards the sun as it
moves across the sky, as with other
solar panels, further reducing efficiency.
The most efficient solar panels track the movement of the sun and have very thin, clear glass. Even these
take approximately a decade to ‘pay for themselves’
