Neither is universally better; the right choice depends on power availability, trenching, solar resource, lighting requirement, battery lifecycle and maintenance.
Grid-connected lights can be efficient where a reliable electrical network already exists. Solar systems can avoid trenching and grid extension in suitable locations, while hybrid systems can add resilience. A lifecycle comparison should include battery replacement, theft risk, maintenance access and required lighting performance rather than only the initial purchase price.
Urban arterials, community paths, remote roads and new developments can have very different optimum solutions.
Whichever power source is selected, compatible luminaires, controllers, poles and asset records can simplify operations.
They can be designed for a required autonomy and dimming profile, but performance depends on solar resource, panel, battery, load and maintenance assumptions.
