Unlike traditional street lighting that is powered by electricity from the grid, solar street lights harness energy from the sun during the day through photovoltaic (PV) panels. This energy is stored in a battery and used to power the light at night.
Benefits include a reduced carbon footprint, cheaper energy bills and additional income when selling the electricity back to the grid. In areas prone to high winds or hurricanes, properly securing PV arrays is.
The total project range for a typical residential energy storage system is roughly $6,000-$20,000, with per-kilowatt-hour pricing commonly spanning $600-$2,000/kWh depending on chemistry, brand, and warranty. In addition to the equipment, expect costs for installation.
