Does it really work with no wiring or electricity?
Yes — there's no wiring and no plug. The solar panel sits on the front face of the number and charges in daylight, storing energy in an internal battery. At dusk, a built-in light sensor turns the backlight on automatically; at sunrise it shuts off. A full 4–6 hour charge runs the light for 8–10 hours overnight. Because the panel is integrated into the number itself, there's no separate solar panel to mount nearby or wire in — which is the main difference between this and a hardwired sign. If your installation spot gets reliable daytime sun, it runs itself year-round with no maintenance beyond an occasional wipe of the panel face.
What happens on cloudy days or in winter?
The internal battery is sized for a full night's run from a single good charge, and it carries a buffer for overcast days. In long stretches of heavy cloud or short winter daylight, runtime can shorten — that's true of every solar address light, since they all depend on available sun. For installations in low-light spots (north-facing walls, heavy tree cover, deep porches), a hardwired option is the more consistent choice. Our hardwired Backlit LED House Numbers run on a 24V transformer for steady illumination regardless of weather, in the same stainless steel and acrylic build.
Is this one number or the whole address?
This is one number. Order one for each digit in your address — a home at 1424 would add four to the cart. Each ships as a complete, self-contained unit with its own solar panel, sensor, battery, and mounting hardware, so they don't need to be wired together or connected in any way. Buying them individually also means you can replace a single number later if you ever need to, rather than the whole set. If you'd rather have your numbers pre-mounted together on one panel, our Metal Backlit Address Plaque ships as a single finished piece.
What's included and how hard is the install?
Each number comes with a paper drilling template, threaded mounting studs, and spacers that create the floating backlit effect. Tape the template to your wall, drill the marked holes, set the studs, and mount the number — about 30 minutes for a typical address, no special tools beyond a drill. It works on wood, brick, stucco, metal, and stone. Because each number is self-powered, there's nothing to wire and no power source to plan around.
