Solar Street Light Comparison Tables
Comparison Tables – Which Is Best For Your Application?
A comparison table between traditional utility powered High Pressure Sodium (HPS) street light, traditional solar street light and Enertia integrated solar street light is presented in the table below. In the table the RED highlights demonstrate disadvantages and GREEN highlights represent advantages.
Red means disadvantages and Green means advantages.

- Recent advances in high performance LED street lights, solar panels, and batteries, now make it more-cost effective to consider solar powered lighting.
- We intelligently apply High Efficiency, High Output LED’s (130lumens/W) with Net output of up to 118 Lumens per Watt.
- We carefully control the power flow within the Street Light with automated microprocessor control of the power going to the LED’s, coming from the sole or combined power sources – Solar and Battery.
- To maximize the solar panel efficiency we use a central microprocessor to perform Maximum Peak Power control which intelligently controls the voltage and current drawn.
Costs – How much does a Street Light cost?
When all of the costs are considered, It is less expensive to purchase and install solar lights than traditional street lights. It is less expensive to operate and maintain solar lights than traditional street lights.
To properly package the integrated solar street light system we custom manufacture our street light to contain all of the components within the head, this includes the battery which is located inside the housing, and for equatorial or high solar radiation areas the solar panel is affixed directly to its top.
