Chips and solar energy battery is the biggest obstacle restricting the development of solar street light the battery capacity is small, the price is very expensive, service life is too short, so the battery become the first loss of the whole solar street light system, LED lights, if
solar integrated IC and battery is containing the development trend of solar street lamps larger block
in the current development trend of solar street lamps short key depends on the following two aspects of
1, the low efficient solar power solar panels, solar power generation solar panels at present stage of generating high efficiency can only be firmly in the teens, still has very big development potential has not development and design, if you can develop design to the utilization rate is above 50%, people's dependence on solar power and solar power as the application of electric energy may be far beyond today's situation.
2, battery capacity
at this stage of the battery capacity is relatively small, the price is very expensive, life is relatively short, therefore, the battery into the first consumable parts of all solar street light system software, LED street lamp, if the battery can have a groundbreaking development trend, then, is blossoming solar street lamps may be far more than that.
although solar power solar panel efficiency is low, but slower attenuation coefficient, the service life is long, so for all solar street light system software, solar power generation solar panels in a certain sense, it is very durable, is basically not changing, at this stage is the most must deal with the problem of the application of solar power generation solar panels efficiency problem.
and the battery must deal with the problem is many, is mainly: the lead pollution of the environment problem, high construction cost problem, life problem and volume problem.
