For a street light that consumes 900WH, after calculation, the battery panel power required by the former =900*1.333/6.2=193.5 Wp, and the battery panel power required by the latter=900*1.333/4.6=260.8 Wp. From this we can conclude that the more sunlight there is, the smaller the solar panels you need and vice versa.
The first step in designing a solar street light system is to find out the wattage and energy consumption of the LED street lights, as well as the energy consumption of other parts that require solar power, such as WiFi, cameras, etc. How to calculate the total energy consumption of your solar system?
Solar street lighting systems usually use lead-acid batteries and lithium batteries (including LiFePO4). The former has low cost, short life, and low discharge depth, while the latter has relatively high cost, long life, good safety, and high discharge depth.
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.
Proper sizing is the most important step in building a solar street light to ensure it will operate reliably over the long term. If you want to learn more about the science of solar sizing, check out our infographic here or download our ultimate solar lighting specification guide.
Solar Street Light Uses and Deployments: 6 Things Should Know
From a price perspective, one cost comparison between standard lights and solar lights in the U.S. showed that while the average solar LED street light costs $3,000 while a standard light is $1,500—the cost of installation for solar lights is quite cheaper. Maintaining each light is also around the same, while the energy consumed is $0 with solar (standalone light) …

Solar panels
Battery storage lets you save your solar electricity to use when your panels aren''t generating energy. This reduces the need to import and pay for electricity from the grid during peak times. For every unit of electricity stored in a battery and used at night, it will save you around 14p. Battery storage tends to cost around £5,000 to £8,000.
