We are all aware that solar panels are used as an alternative source of electricity. You must be curious about the capacity of the solar panel before installing it at your home or elsewhere. And here comes a recurring question: can a solar generator power a house?

I may not be able to answer this question with a single word or sentence. However, after reading this essay, you will have the solution.

How do solar generators work?

A charger controller, battery, inverter, and other components are required to run the entire operation. You can easily run a solar generator if your solar panel contains those appliances.

Initially, the solar panel receives energy from the sun and stores it on the battery. The battery then transfers the entire amount of energy to the appliances. The charger controller serves as a medium in this case. This controller guards against overcharging and overheating. In addition, there is an inverter that generates the charger and converts the electricity from alternating current to direct current. This inverter mostly bypasses the electricity to the appliances, allowing them to run smoothly.

Why should I invest in a solar generator?

You can go entirely off-grid with a solar generator and never have to buy gas again. If your battery runs out, all you have to do is recharge it with your solar panels. It’s really easy and simple to use, and with the increasing use of lithium-ion batteries, some of these generators are lighter than you think.

Solar generator vs. Gas generator

Solar generators

Solar generators are the newest kids on the block. With price decreases over the previous decade, solar energy has become very popular among many households. People typically use solar generators for camping, hunting, and hiking. They are not as popular as gas generators now, but they are gaining ground quickly.

Advantages

  • It can be charged by an electrical outlet or a solar panel.
  • It does not require gas to run.
  • You can put the generator indoors without the exhaust gas and smell.
  • They are relatively low maintenance.

Gas generators

Gas generators have been around for quite some time. Many people use them for camping and in times of emergency. The gas generator burns gas to power a rotor. This rotor goes via magnets, which charge the copper wire. This engine technology is extremely efficient and can generate a huge amount of electricity when required.

Advantages

  • Gas generators are less expensive.
  • They are easy to install (plug and play).
  • They are quick; they fill with gas and switch on.

When should you use a gas-powered generator?

When you require a large amount of electricity quickly, you will most likely employ a gas-powered generator. Gas generators can power high-wattage appliances as long as there is adequate gas available. When the power goes out, most people turn to gas generators. 

When is it safe to use solar generators to power an entire house?

As previously said, solar generators are used for hiking, camping, and travel. You may take a solar generator anyplace because of its portability. Solar generators have become more powerful in recent years, with increased watts and battery restrictions. You can now run many appliances in the house at the same time.

Here is a list of common appliances that a solar generator can power:

  • Radio
  • TV
  • Refrigerator
  • Lights (Low wattage 5-35 watts)
  • Small heater (No more than 600 watts)
  • Cell phones
  • Tablets
  • Laptops
  • AC Unit (only if it’s low wattage and you have your Solar panels charging your generator)

List of Appliances that should not be used with a Solar Generator

  • Ac unit
  • Stoves
  • Heaters
  • Air Blower (You could probably get away with this for a few minutes depending on the wattage of the blower and the solar generator.)
  • Sound systems

Pros

If you reside in a part of the world where sunlight is common and abundant, you will have a significant advantage in using solar electricity to power your entire house.

Assuming you reside in Arizona or Egypt, in that situation, you have a significant advantage for solar energy because certain areas receive more than 4,000 hours of sunlight each year. It is ideal for solar panels to be exposed to direct sunlight for an extended period. More light equals more power!

Another advantage would be to use solar power to reduce your electricity bill rather than fully remove the city’s electrical system from your home. Some people use a few solar panels to power modest equipment such as a television, chargers, an internet router, and a gaming console.

This allows them to save a significant amount of money on their electric bill each month, increasing over time. Then, by reinvesting all of their savings, they buy more solar panels and gradually become completely reliant on solar electricity to power their home, little by little every time.

Cons

If you reside in a part of the world where sunshine is scarce, turning to solar may cost you money. I’m talking about locations like Norway and Alaska, where they only receive a month of sunlight out of the year and have to endure 6 months of complete darkness owing to their geographical location—not ideal conditions for a solar panel.

Another significant downside of using solar power to power your home is that some people cut corners and purchase cheaper components and kits to power their homes. Don’t get me wrong: this may work, but you’ll either waste a lot of energy owing to poor quality solar panels or batteries, or you’ll have a broken component a month into your solar project.

Finally, because solar generators are intended to be used in emergencies, it will require many solar generators and maybe a solar kit to power your entire house. Though it may be costly, investing in a good solar kit may be worthwhile in the long run. 

Is it possible to power a house with a solar generator?

Solar panels are now the best alternative source of electricity. A solar panel will provide you with the best service for the least amount of money. You can run or utilize any electronic item, even a generator, by using a solar panel.

The question now is whether a solar generator can power a dwelling. Yes, a larger generator with a power output of (1000-10000) watts can power a house. Also, which generators are the most reliable in terms of service? You can also select the best portable solar energy generators. Let us now look at the criteria you require.

Calculation of total power

To power the entire house with a solar generator, you must first determine the total power. Total power refers to the appliances that a generator will run. Your home has a plethora of appliances. Assume you wish to utilize a lamp, fan, charger, laptop, and so on. You can easily cover up with a 100-watt solar panel.

However, if you want to run the microwave, refrigerator, television, and other appliances, a 100-watt solar panel would not suffice. This is why you must determine the total power and what you require to run. Then you can answer the question, “Can a solar generator power a house?”

How much electricity do I need to run my house?

To begin, determine which appliances you want your solar generator to power and for how long. Once you’ve compiled this list, you’ll need to figure out how much energy they’ll use. You can do this by consulting your owner’s handbook or by contacting the manufacturer directly.

Once you’ve gathered this information, you can begin shopping for solar generators that will provide enough energy to run your appliances while also leaving some wiggle room.

You’ll want this extra electricity so that your solar generator isn’t always running at full capacity. This causes the solar generator to wear out faster and can drastically shorten the life of your generator.

The average yearly electricity consumption for a household utility user in the United States is 11000 kilowatt-hours (kWh)

The wattage of common home appliances

  • TV – 80-400 watts (40 inches or below)
  • Refrigerator – 1500 watts (This depends on the size)
  • Printer – 8 watts
  • Microwave – 1000 watts (Not Recommended)
  • Freezer – 600 watts
  • Light bulbs – 5-120 watts
  • Fan – 65 watts
  • Laptop – 50 watts
  • Internet Modem – 5 watts
  • Space Heater – 200-600 watts
  • Cell phone – 5 watts

What is a kiloWatt-hour?

KWh is a unit of measurement for the quantity of electricity consumed in an hour. It is just a unit of measurement that equals the amount of energy used if a 1000-watt appliance was left on for an hour.

If a 300 Watt solar panel is exposed to direct sunshine for three hours, your system now has 900 Watt-hours, or 0.9 kiloWatt-hours, of energy.

Simple Conversion Calculation – 1 KW = 1000 W (Conversion factor of 1000)

According to the EIA, a typical dwelling used roughly 30 kiloWatt-hours of energy per day in 2019. Even if we have overestimated the quantity of approximate energy required by 40%, it is always preferable to have more than less because there will be cloudy days, wet weeks, and nights to consider.

Small solar generators (10-250w)

Ready-made solar kits

The best solar generators allow you to buy an all-in-one generator that does not require assembly. These generators are frequently sold with numerous charging options, including solar, wall outlets, and automobile outlets.

They can be bought with or without solar panels, giving you the option of running different panels, and they are an excellent way to get your feet wet with solar energy.

The best part about this type of generator is that it is really easy to use. Most generators will include various plugs that will allow you to plug in almost any gadget you can think of.

Because the hard work has already been done, ready-made solar generators are frequently more expensive than creating your solar generator. However, if you value your time and don’t mind physically charging or plugging in devices, they are an excellent tool to have.

What other items are required?

Most solar generators are sold as an all-in-one package, including batteries, inverters, charge controllers, and, in some cases, solar panels with kits. You may have to acquire these products separately at times, but don’t worry; we’ll walk you through a checklist of everything you’ll need.

Choosing the size of a solar panel

When purchasing solar panels for your solar generator, the size and quantity will be determined by how many items you intend to charge and the total wattage needed. You must also consider panel placement, as larger panels may not fit on some roofs.

Quantity

Depending on the use and the manufacturer, solar panels come in a variety of forms and sizes. Once you’ve determined how much wattage you’ll require, you may look for the appropriate size.

Larger solar panels may have enough electricity to power your appliances. Even so, most of the time, numerous solar panels with lower outputs will be required to generate the necessary power.

Location

The placement of your solar panels will also influence the size of solar panels you require. For example, if you want to install solar panels on your home, you will need to assess the size of your roof and choose the optimal solar panel layout for your application.

If you’re utilizing a ready-made solar generator, stick to the manufacturer’s recommendations for the best solar panel size.

Suggestion for solar panels

This has an djustable, corrosion-resistant aluminum stand with a heavy-duty handle and locks for added durability. Folded dimensions: 19.9 x 27.2 x 2. 8 inches. 500 Watt-hours per day is the ideal output (depends on sunlight availability).

Generator types

There are various types of solar generators available on the market. There will be small, large, and medium-sized generators. Varying generators generate different amounts of electricity. You can configure or select generators based on your appliances.

Small generators provide 250 watts of backup power, whereas medium generators provide 1000 watts. Again, with the larger generators, you can get up to 10000 watts of power back. So, according to your requirements, you may select the generators that will keep your appliances running properly.

Battery types

The battery is also required for running a house’s power using a solar generator. The two most common types of batteries are flooded lead-acid and sealed lead-acid. The flooded battery is inexpensive and provides nearly seven years of battery backup.

The price and quality of sealed batteries have increased, and they provide nearly 5 years of life. The best aspect is that you don’t have to keep this battery charged for an extended period. Choosing the right battery will give you the concept of powering the entire house on a solar generator.

Which batteries should you use?

When it comes to solar generators, you’ll need somewhere to store your energy.

This is when the batteries enter the picture. Solar energy can be stored in batteries and used whenever it is needed. Depending on the application, you may want more or fewer batteries to meet your wattage requirements.

It is critical to evaluate how much battery storage you will require because you do not want too many or too few. Having too many batteries will cost you the money you don’t need to spend, while not enough batteries will result in faster solar energy discharges.

Calculate your wattage usage to determine the type and size of batteries you require.

This is simple to perform by determining which appliances will be powered by the solar generator and summing up their wattage requirements.

Once you know this figure, you can look for high-quality batteries that can store enough energy to meet your needs.

Flooded lead acid

Flooded lead-acid batteries are the most cost-effective choice.

They are reasonably priced and endure for about 5-7 years. You will have to maintain these batteries because they require you to add distilled water every month to equalize the charge.

Furthermore, these batteries will necessitate that the container is vented outdoors to evacuate any accumulated hydrogen gases.

Sealed lead acid

Sealed lead-acid batteries will be the next step up in price and quality.

These batteries will last a little longer than flooded lead-acid batteries, but they have more features.

The lifespan is slightly shorter, ranging from 3-5 years, but there is no need for maintenance.

Gases can be emitted from these enclosures under specific conditions. Hence they should be vented.

Lithium

If you want the greatest battery for your solar generator, I recommend using lithium batteries.

Lithium batteries are the industry standard for high-performance batteries in many industries, and they are an excellent complement to any solar generator.

While they are the most expensive option, they are also the most efficient and fast charging option of the three.

Right inverter

You must select the appropriate inverter because the solar panel distributes electricity and converts it through the inverter. Because if your inverter isn’t working properly, your electricity won’t be distributed properly. Furthermore, this solar generator will not be able to power all of your gadgets.

Choosing the right inverters is thus another option for the solar generator. There are off-grid and on-grid inverters among the generators. When the power is turned on, you can use the on-grid inverter; when the power is turned off, you must utilize off-grid power.

A good inverter will be required to turn your solar energy into useful electricity.

An inverter is a piece of equipment that can be wired on or off the grid, depending on your exact setup.

On-grid inverters

When there is grid power available, on-grid inverters are employed. This will be used on systems when you are supplementing your current electrical supply.

On-grid inverters convert direct current (DC) into usable alternating current (AC), then fed it into your electrical power system.

Off-grid inverters

When your electricity goes out, you can use off-grid inverters to provide backup power.

This is for systems that you use as an electrical backup in the event of power interruptions or blackouts.

Suggestions for solar generator inverters

When selecting the correct inverter for your solar generator, you must consider the size of your solar array or solar panel arrangement.

Because your inverter will be converting all of the DC power given to it, it must be capable of handling as much energy as your solar panels can provide.

In principle, your inverter should be the same size as your solar panel setup’s DC rating. If you have a 6-kilowatt system, for example, you will need at least a 6000-watt inverter.

Of course, this is a general recommendation, and your situation may differ.

Charger controller

The charger controller is a key component of a solar panel. Normally, this gadget is used to control the overpowering of electricity. So, if you want to utilize a solar generator to power the entire house, you must carefully select the charger controller. The solar generator will, after that, run or be used.

How to install a solar generator in your house

When it comes to connecting your solar generator to your home, your options will vary depending on the type of solar generator you choose.

You can create your solar generator to connect to your home’s energy or buy a ready-made solar generator into which you can manually plug equipment.

Let’s take a look at how each approach can be used to link your home.

First and foremost, you must put solar panels on your roof.

A professional can perform this, or you can do it yourself with a DIY kit.

Second, decide if you want to use solar energy as a backup source or replace your home’s electricity.

This will determine whether or not you will require batteries. There will be no need for batteries if you use your solar power for backup.

Then, to transform the solar energy into useful home electricity, install a power converter. You must connect the solar panels to the power inverter and then to the household power grid.

Connect the inverter to the battery and then to the home grid when using batteries.

Install the wire from the battery to the circuit breaker and electrical shunt after that. DC is transported to your inverter.

The shunt and breaker serve to protect the system from overload.

Connect the inverter to the home’s AC fuse box. Connect the AC generator to the inverter to return to conventional power if your solar power runs out.

This is critical if you have had a period of limited sunlight.
