In the solar generator, the solar panels are responsible for converting sunlight into electrical energy. Over time, these solar panels suffer from degradation and lose the ability to generate enough energy for the generator. The average lifespan of these panels is around 20-25 years. The lifespan of your solar panels is an important factor that determines how long do solar generators last.

2. Battery

A battery’s lifespan is determined by the number of charge cycles it goes through. Different solar batteries have different lifespans. Usually, solar generators use lithium-ion batteries. They have efficiency and a long lifespan. The lifespan of an average lithium battery is around 1500-3000 charge cycles, which is close to 7 years, and that too if the generator is used each day. With this, you have learned a usual case of what is the life expectancy of a solar battery.

3. Charge Controller

It’s a part of the generator that regulates the flow of electricity from the solar panel to the battery. It is important as it protects the battery from overcharging and increases its lifespan of the battery. The average lifespan of a charge controller is nearly 15-20 years.

4. Inverter

In a solar generator, an inverter converts the DC from the batteries into the AC used by your appliances. These investors are very delicate and can get damaged by power surges. This is a reason why their lifespans may vary, but any good quality inverter has a lifespan of about 10-15 years. All the components you have studied till now have a large say in how long do solar generators last.

What to Look for in a Solar Power Generator?

After learning how long do Solar generators last, let’s see what to look for in a solar power generator. All solar power generators are not the same and you should choose a solar generator that suits your taste and energy demand. While looking for a good solar power generator, you should consider the following things-

1. Solar Panels: In some generators, solar panels are already present, whereas in others you will have to buy the generators separately. Monocrystalline panels, polycrystalline solar cells, and thin film are the three most common types of panels. Among these three, the monocrystalline panels are the most efficient and common. On the other hand, thin planes are the most affordable and light. These panels also have an important say in how long does a solar generator last.

2. Battery Capacity: You should always check the power rating and battery capacity of a solar generator before buying it. The generators with low power ratings and high battery capacity deliver less electricity, but for a longer period.

3. Battery Type: The most commonly used solar generator batteries are lead-acid and lithium-ion batteries. Lead-acid batteries are great for powering things like automobiles. Whereas lithium batteries are lightweight and mostly used to power tools. These batteries are more expensive than lead-acid ones, but they are long-lasting.

4. Weight: If you are planning to use your generator on the go then you should primarily focus on the weight of the generator. Look for portable generators that are lighter in weight and easy to handle.

5. Charge Controller: These regulate current flow from the solar panel to the battery. The three-point tracking (MPPT) is an efficient charge controller.

6. Inverter: They convert the DC from the batteries into AC to be used by your appliances. They are inbuilt into the solar generators. One of the most efficient inverters is the pure sine wave inverter. It’s expensive though.
