Asking prices can change, and equipment specifications and condition differ between listings.

When comparing the cost of a solar light tower, consider:

1. Purchase price

2. Transportation

3. Battery replacement

4. Routine maintenance

5. Solar-panel condition

6. LED replacement

7. Repairs

8. Expected service life

9. Resale value

For used equipment, compare machines with similar age, operating hours, battery condition, specifications, and configuration rather than relying on a general average price.

Buying a Used Solar Light Tower

A used solar light tower can be a practical option when its battery, solar system, lighting equipment, mast, and trailer are in good condition.

Before purchasing, evaluate:

1. Battery age and condition

2. Solar-panel condition

Battery condition deserves particular attention because a low-hour light tower can still require a significant battery replacement if the battery has aged or degraded.

If possible, operate the lighting system and verify that the panels, charging system, battery, lights, controls, and mast function correctly before purchase.

Solar Light Tower Maintenance

Solar light towers generally require different maintenance than diesel-powered units because they rely on photovoltaic panels, batteries, electronics, lighting equipment, and a mast rather than a combustion engine.

Follow the manufacturer's maintenance schedule and regularly inspect:

1. Solar panels

2. Battery system

3. Charge controller

4. Wiring and electrical connections

5. LED lights

6. Mast and raising mechanism

7. Trailer components

8. Tires and brakes

9. Stabilizers and outriggers

10. Fasteners and structural components

11. Weather seals and electrical enclosures

Keep solar panels clean and unobstructed when required by the manufacturer. Inspect for damage, loose connections, corrosion, and abnormal battery behavior.

Battery service intervals and replacement requirements vary by battery chemistry, operating conditions, cycling, and manufacturer.

Solar Light Tower Safety

Solar light towers should be positioned, deployed, transported, and maintained according to the manufacturer's instructions and applicable jobsite requirements.

1. Important safety practices include:

2. Inspect the unit before each use.

3. Position the tower on stable, suitable ground.

4. Deploy stabilizers or outriggers as specified.

5. Follow the manufacturer's wind and weather limits.

6. Keep people and equipment clear of the mast during deployment.
