How much current does a 42 watt led solar street light have

How much solar power does a street light use?

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.

What is the battery capacity of solar street light?

Therefore, the actual battery capacity might be 210Ah*125%=262.5Ah. Solar street light need work 7h each night, while it is about average 4.5h that solar panel can touch enough sunlight. The voltage of solar panel is 17.4V. It need configure more 20% for power of solar panel. So, Wp=162W.

How to calculate battery configuration of solar street lamp?

Calculation of battery configuration of the solar street lamp 1： First, calculate the current: For example 12V battery system; two 30W lamps, 60 watts in total. Current = 60W ÷ 12V = 5 A 2： Calculate the battery capacity demand: For example the cumulative lighting time of street lamp every night needs to be 7 hours (H) with full load;

How many watts a battery does a street light use?

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.

How long does a solar street light last?

For example: A solar street system, 2pcs 30W LED lamps, 12V lithium battery. For example, the lighting time of solar street light is 9.5h each night, actually lighting with full load is 7h. LED lamp stop to light in 5:00 o’clock (the next day). Requiring continue to light for 5 rainy days (5 rainy days + the last night, it is 5+1=6 days).

What are the key parameters of solar street lighting systems?

Email: [email protected] | WhatsApp: +8615068758483 We aim to introduce the key parameters of the solar street lighting systems, including the power of the street light, the wattage of the solar panel, the capacity of battery, the solar charge and discharge controller and the street light controller.
