How Big a Solar Generator Do I Need for My Home?

How Big a Solar Generator Do I Need for My Home?

Our universe is always advancing, right? So, we need the power we can turn to. Picture this: your food staying fresh during a power outage or staying connected while camping. Enter the solar generator – a green machine fueled by the sun to power your gadgets. Beats those gas-guzzling generators that harm the air. But, not all solar generators are equal. Some are tiny, struggling to run your gear. How do you hand-pick the stellar one for you? Nice, this writing's here for you. Say goodbye to power worries with the best solar generator for your home!

What is a Solar Generator?

Ever thought about making your own sun-powered electricity? Enter the solar generator. It's a cool gadget with solar panels that grab the sun's rays and turn them into power. The magic happens as it stores that power, ready for you day or night. Quick heads up: your devices need a different power type than the sun dishes out. Here's where the power inverter steps in. It transforms sun power into the kind your devices crave. These solar generators? Total game-changers. They silently give you power, no smoke involved. Perfect for home or tagging along on your adventures.

Can a Solar Generator Power a House?

Of course, it can. Then, let's talk solar generators and powering your house. It all hangs on a few facets. Visualize a massive solar generator with an inverter reading 2000 watts or more and a cell from 2,000Wh to 10,000Wh. That beast could keep your whole house running for 2 to 8 hours. Wanna stretch that time? Easy. Just lighten the load on the generator.

Now, peek into the world of Maximum Power Point Tracking (MPPT) and PV input ratings. Some brands might skimp on MPPT electronics to save bucks, messing with your backup time. Here's the tip: a solar generator with a higher PV input rating lasts longer. It can hook up to more solar panels, outlasting the competition.

Charging these generators? You can go with portable or traditional solar panels. But heads up, portable ones cost about 1.8 times more and might not handle crazy winds. If you're rooftop-bound, traditional panels need a solar survey to keep your roof safe.

How Large of a Solar Generator Do I Need for Home? 

To find the optimal size of a solar generator for your house, it is necessary to think about the following:

  • Energy Use: The fundamental metric is your household's monthly power use as retrieved from bills.
  • Occupancy Level: It is essential to customize the generator according to the number of people living in your home. One person living there might need a more compact space.
  • Third, when the power goes off, figure out what you'll need. For low-use applications, a more compact generator will do. You should get a bigger generator with more output and storage if you want to run power-hungry appliances like compressors or air conditioners.
  • Your option is affected by the frequency and length of blackouts in your location, which brings us to our fourth point. One possible solution is to use a smaller generator for less frequent and shorter outages. On the other hand, a bigger, stronger solar generator is required for areas that have protracted power outages, maybe as a result of weather.

How Are Solar Generators Sized?

Now, let's dive into the nitty-gritty of solar generator size – and no, we're not talking physical size!

  • Capacity Matters: When we say size, we mean capacity, measured in watts and watt-hours. It tells you how much power you get from one full charge.
  • Two Key Players: Check out continuous power and peak power.
  • Continuous Power: It's the steady energy flow your solar buddy can dish out. Think about how long it can run your gadgets on a regular day.
  • Peak Power: Also called surge power, it's the max energy for a quick burst. Like when your fridge kicks in and needs more oomph.

So, sizing up your solar sidekick? Look at what your appliances want – both for regular use and that initial power boost. That way, you snag a generator that's up for the job!

Solar vs Diesel Generator

Solar buddies are awesome for boat trips, camping, or chilling at home with low-energy gadgets. They're like the superheroes of clean, quiet energy, perfect for low-consumption needs.

But, here's the twist. If your home craves backup power or dances with high-energy appliances, one solar hero won't cut it. That's when you might wanna consider a diesel sidekick.

Now, pondering, "Should I go diesel?" Check the highlight of the likess and dislikes:

Solar Generator


  • It is clean and silent because it runs on solar power. In contrast to diesel generators, it does not create any noise or carbon dioxide emissions.
  • Due to the lack of moving parts and combustible liquids, it practically never needs maintenance. More so than diesel generators, it's safer.
  • Since it operates on sunlight, it does not require any fuel. In times of crisis, it can help save money and prevent gas shortages.


  • No heavy-duty or high-energy equipment can be powered by it because of its restricted capacity. It has a short battery life.
  • Due to its reliance on sunshine during the day, its charging speed is somewhat modest. Nighttime or overcast conditions will render it useless.

Diesel Generator


  • Powering powerful or energy-intensive electronics is possible thanks to its large capacity. With sufficient fuel, it has a long runtime.
  • Because it can run on gasoline at any time and in any place, it has a rapid charging time. It is not dependent on sunshine or meteorological conditions.


  • Because it runs on diesel, it is both noisy and polluting. Contrary to solar generators, it emit a great deal of noise and carbon dioxide.
  • Due to the moving parts and combustible substances, it needs to be serviced regularly. Plus, it's riskier than solar panels.
  • It requires fuel, which can be difficult to come by and costly in times of crisis. Issues with the gas line or a lack of fuel are also possibilities.
