SAMPLE SOLAR STREETLIGHT SITE PLAN

Solar power station (not to scale) replaces utility transformer connection

Solar powered streetlight

Three streetlights are installed and wired in a conventional manner. The power for the streetlights comes from the “Solar Power Station”.

Approximate solar array size: 96” x 65”

The Solar Power Station can also power irrigation control systems and other loads, Spring through Fall

The Solar Power Station can be configured as an emergency charging station for personal electronics and other devices




STANDARD “CONVENTIONAL” SOLAR STREET LIGHTS

These photos show standard stand alone solar Parking lot, Street/Roadway and Area/Security lights, where

the solar panel is attached to the top of the light pole.

These lights are best used where trenching is difficult or costly.

When installed in shaded areas, this configuration will not function and if aesthetic considerations are of

concern, a central Solar Power Station, as illustrated above, will power any number of standard street lights

(such as the LED streetlight pictured above), by replacing the utility transformer connection.

Parking lot lighting Street/Roadway lighting Area/Security lights

‘INVISIBLE ’ SOLAR PANEL

This innovative solar street light uses flexible

solar PV technology, which wraps the solar

panel around the pole.




HYBRID, A COMBINATION USING THE BENEFITS OF 1 AND 2 ABOVE

Hybrid Solar Street lights combine the aesthetics and variety in style of conventional street lights with the Green aspects

and ease of installation of “conventional” solar street lights while reducing trenching by 45% compared to conventional

street lights. Each Solar Power Supply (SPS) unit connects to 1 or 2 street or parking lot lights.

THE FOLLOWING ILLUSTRATION SHOWS HOW TRENCHING IS REDUCED BY 45% OR MORE COMPARED WITH

A CONVENTIONAL STREETLIGHT INSTALLATION

Street

1 2 3 and 4 5 and 6 Streetlight

Solar Power Supply

Lights 1, 2 are powered by their own individual SPS. With lights 3, 4 and 5, 6, the SPS powers two lights.

Site design will dictate the distance from the lights to the SPS.

SOLAR POWER SUPPLY EXAMPLES

Ground level installation, 12’ high pole keeps solar panels out of reach with clearance for lawn mowers and snow




STREETLIGHT RETROFIT EXAMPLE

The HOA owned light pictured below provides important security and safety elements to the community. As a

result of sidewalks rehabilitation work, the power cable was damaged beyond repair and the light ceased

functioning.

The solar power supply, designed and installed by Solar Electrics, restored power to the light at a lower

cost than installing a new power cable.

The existing 150watt HPS lamp was replaced with a 27watt LED lamp

Should a power outage occur, the light will be unaffected, it’s solar powered. An option is available to

provide community members with 120volt household power to recharge electronics (cell phones,

tablets and laptops) during power outages.

This installation is similar to the Hybrid Solar Street Light on the previous page. Existing site conditions

dictated the location of the solar panel.

In NEW projects, the solar panel can be placed at a greater distance from the light
