Can a Solar Generator Power a House? – Yes, Only If…

Can a Solar Generator Power a House
Written by Jamie Masterson

It is easy to produce renewable energy with solar generators. The power you generate from solar panels can power your entire home. Your whole house or small business can be powered by a solar generator.

In addition to being quiet and clean, solar panels can even be used to reduce your electric bill when combined with existing power grids.

Is it possible to power a whole house with a solar generator? Let’s discuss.

Can a Solar Generator Power a House?

Solar panels are the best alternative to power things, including your home with a lower price tag.

A solar panel will provide you with the best service at the lowest cost. They are used to run a generator as well as other electronic appliances.

Is it possible to power a house with a solar generator? Yes, if you use a generator that runs between (1000-10000) watts will power a house.

You should first figure out how much total power you need to use a solar generator for your entire house. This means how much power you want to supply to all the appliances in your house. A house has plenty of appliances. You might have fans, lights, laptops, chargers, and plenty more.

This can be covered with 100 watts, but when it comes to powering televisions, microwaves, and refrigerators, you cannot use a 100-watt solar panel.

Advantages of using a solar generator

  • Unlimited solar energy

The fuel for gas-powered generators must be continually purchased. No fuel is required with a solar generator. Simply install your solar panels, and you’re set! Let the sunshine do the rest.

  • A green alternative

Clean, renewable energy is the only source of power for solar generators. There is no need to worry about the environmental impact of gasoline, nor do you have to worry about the cost of fossil fuels.

  • Quiet operation

Solar generators are quiet without any moving parts, unlike gas generators.

  • Multiple power sources

One solar generator kit is not enough to power an entire home, but a custom DIY system or multiple solar generators will help. Solar generators with a larger capacity can power larger appliances such as refrigerators, fans, and heaters, but a larger air conditioner or a water heater will require more than one generator or a custom-built unit.

Disadvantages of using solar generators

  • Slow to recharge

Sunlight only charges solar generators. Battery charging takes time. A mid-sized solar generator battery will be charged in 9 hours by a 10-watt solar panel.

  • Limited energy and output

Your house won’t be powered by a solar generator for very long. The power can be used for charging devices and running small appliances. The more solar panels you install, the longer your house will function properly.

  • High initial cost

It is much more expensive to buy solar generators than traditional gas generators. Gas generators cost around $1,000 on average. A solar generator typically costs $2,000.

  • For big power, go big

In terms of solar panels and solar generators, how many devices you intend to charge and how many watts each will require will determine how many panels and generators you will need.

Aside from the size of the panels, you need to consider the location of the panels since some roofs will not accommodate larger panels. As you will be powering your entire house, you will need big sizes to deal with the amount of power you are using.

Factors That Influence the Solar Generator Power Output

Energy Usage

Your energy usage can greatly affect whether you can successfully run your home on solar generators or not.

You need to make sure a solar generator can handle your energy requirements for the time needed.

Sun Hours

A solar panel installation can be calculated based on the number of peak sun hours for an area. Panel efficiency and roof angle affect energy production.

The vantage point of the sun within your house is also affected by obstructions that block the sun’s rays.

Solar panels

  • Size of solar cells

The resistance in a circuit is the barrier that prevents electrons from traveling through it. The shorter the distance, the lower the resistance. So, a smaller cell consumes less energy and is slightly more efficient.

  • Location

You can also have an impact on production by where you place modules on your roof. It is best to place your modules facing south, with the west being a close second and the east as the third option.

In some cases, roofs facing north can provide sufficient production to justify installing panels, but generally, north-facing roofs should not be installed


You must keep your solar panels clean once you install them. If the panels become dirty, they will lose their efficiency.


Most of the sun’s energy is converted to heat, which cannot pass through the system. As a result, solar panels do their best in sunny places, but not too hot. Since cold climates convert more light into energy, solar panels are ideal for cooler climates.


The system will not work at 100% if part of the solar panel is covered by shade. It may even be affected by cloud cover.

Battery type

  • Sealed lead acid

Sealed lead acid

A SLA battery cannot be opened since it does not contain water.

The water in the electrolyte is kept inside the battery by one of two methods: a separator made of absorbent fiberglass in between the negative and positive plates and lastly by creating a gel from the electrolyte.

  • Flooded lead-acid

Flooded lead-acid

Flooded lead-acid (FLA) batteries are the simplest and cheapest deep-cycle batteries. This type of battery has circular lead plates dipped in acid and water-electrolyte solution.

Despite their low cost, FLA batteries are also difficult to maintain because the electrolytes inside the battery undergo evaporation with time, so distilled water must be added often. You will decrease the battery’s lifespan if you don’t add water frequently enough.

  • Lithium

Lithium battery

As the electric car industry drives their development, lithium-ion (Li-ion) batteries are advancing at a rapid pace. On-grid solar battery storage powered by lithium-ion batteries is expected to be the most popular choice for a long time.

Generator type

Solar generators come in many varieties. Small, medium and large generators are available. Each produces a different amount of electricity. Select the generator based on your appliance needs.

You can get 250w of backup from small generators, whereas a medium generator can produce 1000w. You will again be able to get up to 10000 watts from the large generators.

Right Inverter

Inverters convert the solar panels’ energy to electricity, so selecting the right inverter is important. Electricity will not be distributed properly if your inverter is not too great. In addition, this solar generator cannot run all your appliances.

  • Off grid inverters

A system that is off-grid is not connected to the electric grid and uses batteries for energy storage.

The batteries in an off-grid power system can allow the entire home to be powered for up to a year. Whenever there is a prolonged dark winter with little direct sunlight, a system like this can be extremely useful.

Remote locations always use this type. The cost of the system is down to the system’s overall power capacity.  The bigger you go, the more the panels’ number and size also need to increase along with the battery bank and inverter.

  • On-grid inverters

Often referred to as grid-tied solar systems, these types of solar systems are the most common type of solar energy system used in households for their cost-effective nature.

They are typically battery-free and use solar inverters or micro-inverters to work, connecting them to home and grid power.

You can feed your excess power into the system, while obtaining energy credits.

The cost of on-grid systems is directly proportional to the amount of power they can produce. For instance, prices of solar systems range from $5000 to $6000.


Q. Can I design my own solar generator system?

Yes, you can. It does require skill and knowledge, so you need to know how things work before you can start designing a generator system. First, start off with a small one that you can make for a couple of hundred dollars, then move on to something bigger
