How long is the life of household solar lamp

How long is the life of household solar lamps?
What are the factors that determine the service life of solar lamps?
Now let me give you a brief introduction.
Life of household solar lamp.
The normal service life of household solar energy is as high as 25 years, and the battery is expected to attenuate. The normal service life is 5 to 8 years. If the quality of led light source is qualified and the installation and wiring is correct, there will be no problem for 10 years.
You know, the battery of household solar lamp is replaceable, and when the battery life is over, it can be used normally with a new battery.
What are the factors that determine the service life of solar lamps.
1.
Solar panels.
Solar panels, in the form of packaging, are designed to extend their life and protect them from bending.
At present, there are two forms of packaging, which are lamination and glue dripping.
The lamination process can ensure the working life of solar panels up to 25 years. Although the dripping glue is beautiful, its working life is only 1 to 2 years.
Therefore, in order to save costs, many manufacturers will choose the form of dripping packaging, and for solar lamps with a specified service life, it is recommended to use laminated packaging.

Battery.
Because the input energy of the solar lamp power generation system is unstable, it is necessary to configure the battery system to work.
There are usually lead-acid batteries, Ni-CD batteries, Ni-MH batteries and lithium batteries, whose capacity selection directly affects the reliability and cost of the system.
When choosing the capacity of the battery, we should not only meet the lighting at night, but also ensure that the energy during the day is stored to meet the electricity consumption on continuous rainy days.
If the capacity of the battery is too small, it will cause insufficient lighting at night, and the capacity of the battery is too large, which will cause the battery to be in a state of power loss all the time, thus affecting the service life of the battery.
