No grid. No wiring.
No bills.
Off-grid solar LED displays and lighting for sites where trenching power costs $5K–20K — or simply is not possible. Powered by the sun, bright enough to light up the night.

What it is
Displays and lighting that carry their own power station
A photovoltaic array, a LiFePO4 battery and a controller, sized as one system with the load they serve. Where a grid connection means trenching a car park or a highway verge, the solar version bolts to a pole in an afternoon and never sees a meter.
- Reference design: per 440 × 1000 mm display panel — 2 × 100 W mono panels plus a 12.8 V 100 Ah (1,280 Wh) LiFePO4 pack.
- 32+ hours of display runtime with no sun at all, recharging in 8–12 hours.
- Automatic changeover to utility power where a supply exists, so content never goes dark.
Honest engineering
We design to winter, not to summer
The most common failure in solar signage: a system sized on July sun that browns out in January. We size against your latitude's worst-month irradiance and put the assumptions — daily load, autonomy days, recovery time — in the proposal where you can hold us to them.
- Roughly 1.3–2 W of solar per watt of display load, depending on latitude.
- Battery Wh ≈ daily load × autonomy days ÷ 0.9 depth of discharge.
- If the maths does not close for your site, we say so before you buy.
The range
Four ways off the grid
Displays, lighting and traffic products on the same storage platform.
Lighting
Street lights
All-in-one 30–300 W with panel, battery and LED integrated. Microwave motion dimming, 12 h per night with 3–5 rainy-day autonomy.
Traffic
Radar speed signs
Solar radar speed signs for school and work zones, built to MUTCD requirements, trailer or pole mounted, with 4G fleet management and GPS.
Billboards
Billboard lighting
Solar flood kits for static boards and fully solar digital signage in small formats — HOA monuments through to highway advertising.

Buying note: municipal and DOT work is bid-driven and needs MUTCD compliance — the longest cycle but the stickiest contracts. Private and rural buyers close fast when the alternative is a $5K–20K trench. Solar incentives can cut project cost 10–25%, and we flag what applies in your region in the quote.
Why it wins
Why these systems are still running in year five
01
Winter-first sizing
Autonomy, load and recovery calculated against worst-month sun and written into the proposal, not assumed from summer performance.
02
Real LiFePO4
2,000+ cycle packs that last 5–10 years, against roughly two years for the lead-acid hiding inside budget imports.
03
Installed in an afternoon
All-in-one units bolt straight onto existing poles. No trenching, no cable runs, no utility connection paperwork.
04
Fleet management
4G and GPS on traffic products: brightness, schedules, battery health and location monitored from one dashboard.
05
Anti-theft by design
Locked battery compartments and pole-integrated storage on public deployments, because exposed batteries walk.
06
Grid fallback
Display signs change over to utility power automatically where a supply exists, so a bad weather week never blanks the screen.
Where it works
Anywhere the sun reaches and the grid does not
Typically where a power connection costs more than the display itself.

FAQ
What buyers ask first
How long does it run without sun?
The reference display design runs 32+ hours with zero sun and recharges in 8–12 hours. Street lights carry 3–5 rainy-day autonomy at full schedule. Your site's figures are calculated from local irradiance data and written into the spec.
Why does battery chemistry matter so much?
It is the single biggest quality difference in solar products. LiFePO4 delivers 2,000+ cycles, which is five to ten years of nightly use. The lead-acid packs inside cheap imports typically die at around two years — usually just after the warranty. Battery type is the first line of every SmarTech solar quote for that reason.
Will it survive winter?
That is exactly what we size for. We use your latitude's worst-month solar data rather than an annual average, and we state autonomy days, daily load and recovery time in the proposal. If the maths does not close for your site — deep shade, far north, 24-hour duty — we tell you before you order instead of after.
Are the radar signs compliant for public roads?
Our radar speed and school-zone signs are built to meet MUTCD requirements and come with 4G fleet management, suitable for municipal and DOT procurement. Test and compliance documentation is available for bid submissions on request.
What maintenance does a solar system need?
Panel cleaning once or twice a year in dusty locations, and a battery replacement at the end of its cycle life — typically year seven to ten. There is no lamp to change and no cabling to inspect. Fleet-managed units report battery health remotely so a failing pack surfaces before it strands a site.
Can I add solar to a display I already own?
Sometimes. It depends on the display's average and peak draw and whether it can accept DC input or needs an inverter. Send us the model and duty cycle and we will calculate whether a retrofit is economic or whether replacing the head is the better spend.
