Solar generators are certainly the need of the hour. I have seen a lot of people getting rid of electricity and gasoline bills by switching to solar generators. You can also utilize solar generators during sudden power outages.

The size of solar generators depends on your power needs. A 3000W5000W generator is enough to run your whole house. You can increase or decrease the size of the generator according to your requirements.

In this blog, I’ll let you how to find the correct size solar generator for your house. So, without further ado, let’s get straight into it.

Can A Solar Generator Run A Whole House?

What Size Solar Generator Do You Need To Run A House

Many of you might be thinking whether a solar generator can run a whole house or not. A solar generator can undoubtedly power your whole home. Nevertheless, it depends upon the size of your solar generator, your power needs, and your house’s size.

A solar generator consists of solar panels, an inverter, a battery, and a charge controller. Solar panels fetch power from the sun and store it in the battery. The solar inverter will convert DC into AC electricity and supply power to your appliances during a power blackout.

If you own a huge household and an average size generator, the solar generator will be unable to power your whole house. Therefore, let’s move along and explore the tactics to find the right size of solar generator for your home.

Determining The Right Size Of Solar Generator

Here are a few factors that will help you to grab the correct size of solar generator:

Average Electricity Usage

The initial factor to consider is the average electricity usage of your house. All you have to do is grab the past year’s bills and divide the total kWh by 12. This calculation will give you the average electricity consumption of your house.

You can also determine the power consumption difference during the summer and winter seasons.

Wattage Requirements

Wattage needs are also mandatory after average power consumption. You can identify your wattage requirements by following the steps:

  • Make a list of your devices and estimate the power needs of each appliance separately. Heavy appliances like refrigerators require more wattage as compared to a laptop.
  • Now add the wattage of all the devices to determine the total wattage requirements.
  • I’ll suggest you always leave a safety margin while finalizing the wattage requirements. It will protect your solar generator from overloading and damage.

Power Blackouts Frequency

One crucial factor that many of you always ignore is power blackout frequency. The size of the generator will be altered with the change in frequency.

For instance، if you’re living in an area where power outage frequency is 40%, you need a large generator to cope with this situation.

Meanwhile, if the blackout frequency is only 5-10%, a medium size generator will be enough to light up your house in an emergency.

Electricity Consumption During Power Outage

I have analyzed that power consumption during blackouts is also an essential thing to consider. Whenever you think about having a solar generator, you must think about the electricity you need to run particular appliances.

So, assess the power requirements of your house during a power outage and purchase your solar generator accordingly.

Solar Panel Setup

Evaluating the solar panel setup is also a significant factor. Solar panels are the power providers of a solar generator. You should always buy a similar efficient battery so that the panel can generate significant power, and the battery can store it well.

Benefits Of Solar Generator

Here are a few advantages of solar generators:

Cost Effective

Various folks think solar generators are expensive due to their initial cost. Undoubtedly, the initial investment in solar generators is more than in typical gas generators. But it’ll save you money from the electricity bills.

The best thing about solar generators is they work on free sunlight from the sun. So, there’ll be no need to worry about the expenses of fuel every second day.

Solar generators are stated as Eco-friendly because they do not emit harmful gases like traditional gas generators. If you’re looking for a pollution-free backup for your family, solar generators are the best choice.

Low Maintenance

If you’re tired of the high maintenance of gas generators, shift to the solar generators now. You might be aware that there’s no moving part in the solar generator so there’ll be no fear of tears and repairs. So, solar generators rarely want any replacement.

Therefore, get your solar generator now and forget about the hectic repairs of generators.

Another benefit of solar generators is their reliability. No matter where on Earth you’re living, you’ll get power as long as the sun is there. There’ll be no tension in getting fuel on time to overcome power outages.

Moreover, you can store the power in the battery to deal with climate change.

Energy Independence

Energy independence is an excellent feature of solar generators. As you know, typical gas generators work on fuel. If the fuel isn’t refilled on time, the power supply will be stopped.

In contrast, if you go for a solar generator, you don’t have to worry about gasoline issues. Solar panels get energy directly from sunlight and convert it to the electricity that will power your house.

Noise Free

Noise is the drawback that I hate about all the typical generators. There’s a misconception that all generators make noise. You’ll be amazed to know that solar generators don’t make noise as there are no moving objects inside them.

Therefore, solar generators provide you with power without disturbing your work.

By now, you know all about the wattage requirements and size of solar generators. A correct-size generator will be able to run your whole house. If you have purchased an average size solar generator, but your needs are going to the sky. You’ll damage the generator.

Remember! only a suitable size solar generator can handle the power requirements of a particular house. Hence, skim the writing carefully and estimate the right size of your solar generator.
