It is noted that solar electric and battery powered devices have performed well with minimal battery drainage in northern locations such as New Hampshire, Massachusetts, Pennsylvania, Delaware, Washington, D.C., and West Virginia. Colder solar insulation is more efficient than that of a tropical nature as lower temperatures tend to increase solar cell output. Reasons for prefering the solar arrow panel are listed. West Virginia's experiment with solar-electric arrowboard equipment is described. The equipment is more costly than traditional arrowboards, but the price difference is recaptured in 6-8 months of use. These boards contribute to a greater degree of work zone safety. Two major obstacles to widespread use of the equipment are as follows: the bureaucracy inherent in the state specification process; and supply companies that have already invested capital in the traditional arrowboards.
