20-Watt Solar Street Light

The SSL-20 reaches about 2,200 lumens when motion is detected, making it a stronger option for localized parking areas, entrances and traffic zones than lower-output accent or pathway lights. Whether that is enough for a particular site depends on the size and layout of the area, mounting height and the light level required at the ground.

For a full commercial parking lot, fixture count and placement should be based on the site's lighting requirements rather than lumen output alone.

A reference spacing of more than 12 meters, or about 40 feet, is documented for this fixture. That figure is useful for initial planning, but it should not be treated as a universal spacing rule.

Required spacing changes with mounting height, site geometry, obstacles, desired uniformity and the amount of illumination needed between fixtures.

The recommended mounting range is approximately 3–5 meters (10–16 ft). Within that range, a lower installation concentrates the light over a smaller zone while a higher position can spread it over a broader area with less intensity at any one point.

The final height should also preserve useful PIR sensor coverage and provide a structurally secure installation.

The SSL-20 is designed to illuminate automatically after dark at its lower output rather than remaining off until movement occurs. When the PIR sensor detects activity, the fixture increases to its brighter mode and then returns to normal nighttime output after the activity subsides.

This combines continuous background visibility with additional light when a person or vehicle approaches.

A full charge requires approximately 6–8 hours of strong direct sunlight. The system has documented backup autonomy of up to 48 hours, but actual performance depends on the charge accumulated beforehand, weather, season, shade and how frequently high-output motion mode is triggered.

Several consecutive low-sun days can therefore reduce nighttime runtime even though the fixture has battery reserve.

The PIR sensor has a documented detection distance of approximately 16–33 ft with a detection angle below 140 degrees. Actual detection can vary with mounting height, approach direction, temperature and site conditions.

The light itself has a 120-degree beam angle, so motion-detection range and illuminated coverage should be treated as separate specifications.

Yes. The fixture includes wall and pole mounting hardware and can be mounted to a suitable wall, siding or pole. Compatible pole mounting extends to approximately 3.25 inches for round or square poles.

The support pole is not included, so an existing compatible pole or a separately sourced pole is required for pole-mounted installations.

The SSL-20 does not require a grid-power connection, so normal installation does not involve trenching an electrical feed to the fixture. Its solar panel, battery, LEDs and control system are integrated into the lighting system.

Professional installation can still be appropriate when a new pole, structural mounting, work at height or site-specific safety requirements are involved.

It can be used in parking areas and other commercial outdoor spaces, but the SSL-20 should not be assumed to satisfy an entire parking lot with a predetermined number of fixtures. Commercial projects may have minimum illuminance, uniformity, security or local-code requirements that determine the correct fixture output, pole height and spacing.

For a larger or compliance-sensitive site, use a proper lighting layout or photometric plan before purchasing fixtures.
