Solar Street and Parking Lot Lights

Unlike other forms of solar lighting, the solar street light does not come in a “one size fits all” package. Many factors have to be taken into consideration. The climate conditions, levels of solar radiation expected and implementation all need to be properly assessed before a solar street light can be confidently installed. This is because street lights matter. They matter for our safety behind the wheel and on the sidewalk.

A street light with a low-pressure sodium lamp can be powered by solar. Low-pressure sodium (LPS) lamps have an outer glass vacuum around the inner tube to improve thermal insulation and loose less energy through heat. A low-pressure sodium light is at the peek sensitivity for the human eye and is considered an energy efficient light source for street light purposes.

An LED street light can consume just 80 Watts and produce 5600 lumens of high quality light and have 0% wastage. Comparatively standard street lights use 250 Watts per hour. This massive energy saving is what is prompting many states to start switching to cost saving solar street lighting.

A solar street light will have battery back up for cloudy or rainy days and will run on Direct Current (DC) so there is no extra cost for inverters, transformers or meters.

Installing solar street lighting will means there is less trenching for wires and cables, only the battery needs to be placed underground and this will cause less disruption to the area.

The same LED bulbs and photovoltaic panels are being used in parking lot lighting as well. This system enables light to be placed advantageously to increase security. With the solar lights freedom from wires, it can be placed in areas that were unreachable for electric lights.

The light output of standard parking lot lights is 200-400 Watts and a solar LED parking lot light can produce that using an 180w solar panel.

It will not only match the strength of a standard parking lot light, it will also outperform it. The average life span of a LED is 100,000 hours. This is far greater than the standard bulb used in parking lot lights, so less need for replacement. And because there are no wires or meters in solar lighting, there is less room for mechanical error.
