At Carmanah, we have used our 20-plus years of experience to perfect our flashing beacons, which are available in both solar and AC versions. Solar-powered traffic beacons have fast become the preferred choice for crosswalks, school zones, and warning signs, but there are times when AC-powered systems make sense.
When would I choose solar over AC power—or vice versa?
Solar and AC are both viable power supplies for flashing beacons, but sometimes, one may be more practical, cost-effective, or efficient in a given location. Anything from shading to intensity requirements to beacon usage to distance from the power grid will affect which solution is best for a given project. Here are a few reasons you might choose one or the other.
Top 3 reasons to choose AC power systems
AC power is readily available:
Location is heavily shaded:
AC will be more reliable if there wouldn’t be enough sunlight reaching the solar panel to keep the battery charged during the worst winter weather. The best way to determine if shading is a problem is for Carmanah to conduct a free assessment and provide you with our site-specific Energy Balance Report™ (EBR).
Location, application, or conditions dictate AC requirement:
What’s an Energy Balance Report (EBR)?
No matter where you install your digital advisory speed sign or crosswalk beacon, we can run a comprehensive site assessment to confirm the best solar-powered solution for your project. We run a field-proven software simulation to create an Energy Balance Report™ to show you how we did it. Best of all? It’s free, and we can have it ready in under an hour.
