Information Display Co. (IDC) introduces the "Easy-Solar" version of its SpeedCheck driver feedback sign. With the Easy-Solar system, the battery and all other power system components are contained within the SpeedCheck sign. Its one-piece integrated design makes the Easy-Solar package significantly easier and less expensive to install. The sign features a built-in timer to limit energy use during nighttime and off-peak hours, providing an economical alternative to 24/7 systems, which require bigger batteries, separate enclosures and often multiple solar panels. To install, users simply attach the solar panel and display to the pole, connect the 12-volt power lead from the panel to the display, and program the timer. Once the pole is in place, installation can be completed in less than an hour.
