NTPEP (National Transportation
Product Evaluation Program) is a
committee of AASHTO (American
Association of State
Highway Transportation
Officials) that
originated in 1994.
The key objective of
NTPEP is to provide
quality testing and evaluation of
products, materials, and devices that
are commonly used by the AASHTO
Member Departments of Transportation.
Testing by NTPEP is optional and some
manufacturers decline having their equipment
tested. SOLARTECH had both our
SILENT MESSENGER
Changeable Message Sign
and SILENT SENTINEL
Arrow Board tested. The
evaluation consisted of day
and night legibility, day and
night angularity, luminance, and run time
(total number of days the unit can run
without recharging) testing. Each piece of SOLARTECH equipment evaluated returned
above average results and proved that our
equipment is indeed some of the best in the
industry.
SOLARTECH feels that the NTPEP testing is extremely beneficial as the test results give us a great idea of how our machines stand up next to the competition and allow us to continually refine and develop our products.
