A solar generator is not just a terrific method to have power backup for your house or workplace, but there are also a few portable solar generators available that are ideal for camping or emergencies.

But the question here is how long these solar generators can last. Continue reading to find out how long your solar power generator will last.

The Average Life Span of a Solar Generator

Solar generators have a charging cycle life of a few hundred to a few thousand times. The solar generator’s battery is the most important component that determines its lifespan. As a result, the life span varies depending on the battery type – lithium-based batteries have a longer life cycle than lead-acid batteries. As a result, it goes without saying that generators that are charged and discharged more frequently would have a shorter lifespan.

Below we have covered some details on each part of the solar generator as for how much time it can last.

Solar Generator Battery

The amount of charge cycles that a battery goes through determines its lifespan.

To put it another way, how many times have you charged and discharged the battery? Solar generators, unlike diesel generators, include a high-quality lithium battery. This battery is well-known for its long life and high efficiency.

The usual lithium battery has a life expectancy of 1500-3000 charge cycles, or about 7 years if you run the generator every day. Also, by keeping your battery in between 20% and 80% you will enhance its longevity.

Solar Panels

Some generators come with built-in solar panels, while others require separate purchase and installation. Solar panels are long-lasting gadgets with a 20-25-year warranty. Solar panels do not deteriorate physically due to the lack of moving parts, and they do not require any maintenance other than cleaning.

Charge Controller of Solar Generator

A charge controller, also known as a charge regulator, is a voltage and/or current regulator that prevents batteries from becoming overcharged. It adjusts the voltage level going to the battery from the solar panels.

This component is crucial because it prevents the batteries from overcharging and helps them last longer. The charge controllers of solar generators have a lifespan of 15 to 20 years.


Solar generators transform solar energy into a usable electrical current by combining a solar panel, voltage regulator, battery system, and inverter into a compact system.

A power inverter, often known as an inverter, is an electronic device that converts DC from batteries or solar cells into AC (alternating current) current for use in appliances. An inverter can be built to extract DC power from either batteries or solar panels.

Solar inverters on panels normally last 10-12 years and need to be replaced at least once during their lifetime. Solar panels require power inverters to operate safely and efficiently.

Considering all the above-mentioned facts, a solar power generator can last for over 25 – 30 years if used properly and maintained from time to time. Moreover, most of the time it is one time lifetime investment. The best thing is that most solar generators come with warranties so if anything goes wrong you can just ask for a replacement or any certain fixes from the brand you bought from.
