Maintenance Expenses 

Generators have so many moving parts that can face wear and tear after a short time period. If any part of the generator breaks, it’ll stop working appropriately. Hence, the generator comes with a lot of maintenance expenses including fuel costs. 

Noise Pollution 

Noises are too annoying for me while working. Let me make it clear to you that a generator makes a lot of unwanted noise. This noise can be due to moving parts inside the engine. Moreover, generators also release toxic gasses that are dangerous to your health. 

What Do You Know About Solar Panels?

Which Is Better A Generator Or Solar Panels?

As the name illustrates, the solar system works on solar power. Solar panels gain energy from the sunlight and store it in the battery for later use. Solar panels are designed to convert sunlight to DC electricity. 

The solar system also contains an inverter that converts DC to AC electricity to run your appliances. You must know that the equipment including microwave, fridge, tv, etc, only works on alternative current. 

Let’s delve in and explore more about solar backup systems. 

Components Of Solar System 

The components of the solar system may vary according to your solar setup. Here are the basic components of the solar system. 

  • Solar panels are the initial components of a solar system. It fetches energy from sunlight and converts it into direct current to store in the battery.
  • Another component of the solar system is the charge controller. A charge controller helps you to monitor the charging and prevent the battery from overcharging or undercharging. 
  • The battery is the major component of the solar system that stores DC electricity. It will provide you with a power supply for later use when sunlight is not available. 
  • An inverter will convert the DC electricity into AC electricity to power your home appliances. 

You might be aware that the modern solar system contains a backup generator with them. It helps to provide a power supply more efficiently. 

Applications Of Solar System

A few applications of solar panels are given in the following. 

  • Solar panels are used as a reliable source of electricity to cope up with emergency circumstances. 
  • Solar panels are best for off-grid locations to provide electricity from natural sources of energy. 
  • You can also use solar panels to reduce the electricity expenses of your businesses. Solar panels work incredibly during day time. 
  • Solar backup systems are also being used in the campsites and remote villages to fulfill electricity requirements for free. 

Pros Of Solar Panels

The benefits of solar panels are given below. 


You’ll be amazed to note that solar backup systems do not produce any annoying noise. This is because there are no moving parts present in the solar system. So now you can do your work peacefully without any noise even in power outages. 

Low Maintenance 

As I’ve discussed before, solar panels don’t contain any moving devices in them. So, there’s a low to zero chance of any breakage or repair. Therefore, you don’t need to go for high maintenance while having a solar system for backup electricity. 


The best thing about the solar system is it doesn’t excrete any toxic gasses like other traditional generators. If you’re worried about the toxins of generators due to fuel usage, don’t worry. Expel your typical generator and grab the new solar system now.
