Solar street lights use clean energy and use battery panels to convert solar energy into light energy to provide lighting services. It is widely used in both urban and rural areas in my country. Not only street lights, but also garden lights, etc., all use solar power. The solar street lamp lithium battery stores the electric energy of the solar panel and can be used for lighting at night.
As we all know, lithium batteries are widely used in today's society and are an advanced battery type. The main lithium battery used in solar lights is lithium iron phosphate energy storage battery. So, do energy-saving and clean solar lights use lithium iron phosphate batteries?
In fact, there are lead-acid batteries in use at the same time. Compared with lithium iron phosphate battery, its disadvantages are:
1. Low energy density
The same is 48v12Ah, the lead-acid battery is the only 33Wh, while the solar street lamp lithium battery can reach 125Wh
2. Service life
Lead-acid batteries have 60% capacity after 300 cycles, while lithium iron phosphate batteries still have 80% capacity after 1500 cycles
3. Not environmentally friendly
Lead-acid batteries will produce pollution, and lithium batteries are recognized as environmentally friendly batteries.
Since there are so many shortcomings, why are lead-acid batteries still in widespread use? Mainly because of their mature products, low prices, and easy maintenance. So it is still the mainstream of the market.
But with the restrictions of national industrial policies, market share is declining. The market share of solar light lithium batteries is gradually increasing, and the prospects are broad.
