Compare estimated 5- and 10-year costs for solar and grid-powered street lights, including equipment, installation, electricity, and maintenance.
Enter the local equipment, civil-work, and energy costs for both options. The comparison is most useful when the two layouts provide equivalent lighting.
Solar can avoid a new electrical supply and long cable trenches. It still needs foundations and any required permits. Grid lighting may cost less where suitable power infrastructure already exists.
Include battery replacement and access labour in the solar budget. For grid lighting, include electricity and expected driver or lamp maintenance. Use the supplier’s proposed service intervals for both.
The emissions comparison covers avoided grid electricity during operation. It does not include manufacture, transport, batteries, or disposal. Use a current local grid factor for reporting.

Grid lights require trenching for underground cables. Solar lights need zero trenching.

Common questions about solar vs grid street lighting costs
Either option can have the lower total cost. Solar may save on grid connection and cable installation; grid lighting may cost less where infrastructure is already in place. Compare local quotes over the same period.
The break-even point depends on the difference in installed cost and annual operating expenses. Use site-specific quotes and battery-replacement assumptions rather than a standard payback range.
Obtain a civil-work quote that covers trench length, reinstatement, permits, and site conditions. Solar can avoid power-cable trenching, but foundations and other civil works remain.
Use the battery supplier’s expected replacement interval under the proposed temperature and cycling conditions. Include parts, access, labour, and disposal in the cost.
Backup duration depends on usable battery capacity and the nightly load. Ask the supplier to show the energy calculation for the required cloudy-weather period, including seasonal solar conditions.
