To power a 12V solar street light for 12 uninterrupted hours (19:00 to 07:00) considering losses due to an 80% round-trip efficiency, a DOD of 50%, and taking 2 days of autonomy, you would require a 75Ah@12V battery for the 1,500-lumen fixture and nearly 600Ah@12V battery bank for the 12,000-lumen street light.
Total volume of the battery will be as follows: for lithium battery, battery capacity = Total street light use *2 / 0.8 / 0.9 = 1167 WH, while for lead acid battery, battery capacity = Total street light use *2 / 0.7 / 0.9 = 1333 WH. So the battery should be rated 12 V 100 Ah (lithium battery) or 12V 120 Ah (lead acid battery) for 2 day autonomy.
Lithium-ion phosphate batteries: If you are looking for high capacity, longer lifespan, safety, and a compact size. Every solar battery has a set of pros and cons. So, the final selection of the battery for your solar street light depends on the budget, weather in your area, daily solar energy requirements, maintenance, etc.
To size the capacity required for the battery, it is valuable to use the expression below: As an example, we can take a 1,500-lumen fixture that consumes nearly 15W, while a 12,000-lumen solar street light consumes 120W.
Lithium batteries are a more advanced technology delivering around 4,000 cycles while operating at an 80%-100% DoD. Each battery has a different type of safety certification, regarding electrolyte chemicals and the manufacturing process. Solar street lights require a battery with UL-8750 certification or a safer one.
Solar street lights require a battery with UL-8750 certification or a safer one. One major aspect to consider in safety measures is avoiding batteries falling under thermal runaway, this can rapidly heat the battery and cause it to explode or release hazardous gases.
