Are solar sign lights bright enough for billboards?

Yes. Commercial-grade solar LED sign lights deliver 8,000–12,000 lumens per fixture, suitable for large signage.

What’s the ROI for solar billboard lighting?

Most systems achieve ROI within 3–5 years due to avoided trenching and monthly energy costs.

Do solar lights work during cloudy weather?

Yes. Quality systems feature 2–3 days of battery autonomy and weatherproof components.

Can solar lighting be used on monument signs?

Yes. Smaller solar kits are ideal for entry monuments, retail signs, and off-grid displays.

Why Solar-Powered Sign Lighting Is the Smart Investment for Remote Sites

Connecting power to a remote billboard or monument sign sounds simple until you price out trenching, permitting and utility fees. In many cases, the cost of running power ends up being higher than the sign itself. That’s why more businesses today are choosing solar powered sign lights instead of traditional wired systems.

Good quality commercial solar sign lights are designed specifically for billboards, entrance monuments and branding signs in locations where grid access is costly, delayed or simply not available. They install quickly, require no trenching and operate for years with no monthly electricity cost.

Why Solar Is the Smarter Financial Decision

No trenching or underground conduit
No utility coordination or power company delays
Zero electricity bills after installation
Ideal as billboard lights, monument sign lighting, and rural signage
Installs in 1 to 2 days instead of multiple weeks
Typical ROI recovery in 3 to 5 years

Over a 10-year span, the savings from solar billboard lights often exceed $15,000 to $25,000 compared to grid-powered systems.

Cost Comparison

Expense Category	Grid-Powered Setup	Solar billboard lights
Trenching & conduit	$10,000–$20,000	$0
Permits & inspections	$1,000–$2,000	Minimal
Electricity cost	$400–$600 per year	$0
Installation time	2–6 weeks	1–2 days
Lifespan	5–7 years	10–15 years

Performance Capabilities of Today’s Systems

Real Project Example

A marketing group in West Texas needed lighting for a highway billboard more than 8 miles from the nearest power source.

Grid option:

$15,000 trenching
$2,000 permitting
$500/year in utility fees
10-year cost: $22,000+

Solar powered sign light solution:

Two high-output fixtures: $6,800 total
No monthly operating cost
10-year cost: $6,800

Savings: $15,000+
Payback time: Under 4 years

Key Things to Plan For

Light positioning
Fixtures are usually mounted at the top or bottom and angled toward the sign at 30–45 degrees. A 14×48 ft billboard generally needs 2 to 4 fixtures.

Battery autonomy
Look for systems that hold 2 to 3 days of energy storage so performance stays stable in winter or cloudy periods.

Durability
Good systems carry at least IP65 protection to resist water, dust and corrosion for long-term outdoor use.
