What is the lifespan of off grid solar system kits?

Off grid solar system kit is not simply a machine, but an integrated system which made by the solar panel, storage battery, controller, inverter and other accessories. Each component work coordinated but independent, performance is not the same, service life is also great difference.

The solar panel lifespan is 20-25 years. Which is made from the surface’s tempered glass, anti-aging EVA glue and TPT back plate laminated, can be placed outdoors for a long time, accept light and power generation.

ice life is also great difference.

According to the size of battery , the service life of 40ah is 3-5 years, and more than 50ah is 5-8 years. For life service, there is a great relationship with operation method and working environment . If the off grid solar system is often deep discharged, it will shorten the life cycle, especially has not been timely charged after deep discharge . Besides, storage batteries are self discharge, if not used for a long time, should ensure charge and discharge at least three months.

The controller of off grid solar system kit service life is 8 years. The controller's performance is quite stable, generally not easy to appear the problem.

The inverter of off grid solar system kit service life is 8 years. It has a great relationship with working environment. Long time full load carrying will shorten the service life of inverter, especially over the load of electrical power capacity cause damage. In generally, while the load power is not more than 80% of its rated power. When in using, should pay special attention to the use of electrical appliances.

Overall speaking, Due to the relative independence, each component of the off grid solar generator can be easily maintained, also can be replaced when the problem occured, keeping the system can be used continuously.
