What Is A Portable Solar Generator?

A portable solar generator is a device that converts sunlight into electricity. It takes energy stored in a battery or uses it directly to power small electronic devices, making them eco-friendly and silent.

They are popular for outdoor activities, emergency preparedness, and off-grid living due to their multiple outlets, USB ports, and portability.

Having a backup power source is crucial, whether connected to the grid or not. Portable solar generators provide a quieter and more sustainable alternative to traditional gas-powered ones.

Understanding solar technology can be challenging, but I’ll simplify it for you in this article.

How Portable Solar Generators Work?

Portable solar generators have the same key components that you find in home PV systems.

1️⃣ First up, there’s the solar panel. Solar panels work by converting sunlight into electricity. It comprises many photovoltaic cells that transform energy from the sun into direct current (DC) electricity. 

2️⃣ Then there’s the battery bank, like a big rechargeable battery that stores all that DC electricity until you need it.

The bigger the battery bank, the more energy you can store and the longer you can use it. The battery enables you to use the power at night or whenever the generator is not receiving sunlight.

3️⃣ Next, the inverter converts all that DC electricity/energy stored in the bank and converts it into alternating current (AC) electricity, which is what your devices run off. 

4️⃣ And finally, there are the ports and outlets. These are what you use to connect your devices to the generator.

They’ve got USB ports for your phone, AC outlets for your laptop, and even 12V ports for your car fridge. It’s like a little power hub that keeps all your gear up and ready to roll.

For a deep dive into each of these steps, I’ve written an entire article explaining how portable solar generators work.

Benefits of Using a Portable Solar Generator

So, what are the benefits of using a portable power station? Well, that depends on what you are using the generator for and in what conditions you are using it. That said, here are a few advantages and benefits:

♻️ Clean and Renewable Energy: Most generators use fossil fuels, which harms the environment. Well, solar generators are different because they use the sun’s energy to generate clean energy. 

💼 Portability and Convenience: Picture this: you’re out in the middle of nowhere, but you need to power your mobile phone and charge your laptop. What do you do? Well, bust out your trusty portable solar generator, which is designed to be easy to move around and take wherever you go. 

🫰 Cost Savings: Admittedly, solar generators have a high upfront cost, but they can save on electricity bills over time and reduce reliance on traditional power sources, benefiting your wallet and the environment.

🤫 Quiet Operation: Unlike those obnoxious traditional gas generators, they are super quiet and don’t emit any pollution. They’re like the library of power sources – perfect for use in quiet outdoor settings or situations where noise and emissions are a no-go.

🔩 Low Maintenance: These generators require little maintenance beyond the basic cleaning and upkeep now and then. They are like the “set it and forget it” of power sources. So, you can spend less time tinkering and more time enjoying the great outdoors.

If it sounds like I am a fan, it is because I am. They have a lot of benefits, and even if you feel like you do not need one, they are fantastic to have around.

Limitations of Portable Solar Generators

It is all too easy to discuss the benefits. However, what about their limitations? Perhaps they are not the correct type of power source for you. Well, let’s take a look:

Limited Power Output: They might not be able to handle all your power-hungry gadgets, so you have to choose which ones you want to keep alive.

⛈️ Weather-Dependent: Solar runs on sunshine, so your power supply will too if the sun’s hiding behind the clouds. That said, solar panels are becoming more efficient.

🪫 Limited Battery Capacity: These generators can’t hold a ton of juice in their batteries, so you must be careful about how much power you are taking out of them.

🐌 Slow Charging Time: Unlike traditional gasoline generators, they can take their sweet time soaking up the sun’s rays and charging their batteries.

💰 Initial Cost: These machines don’t come cheap, but you might be able to save some dough on your energy bill in the long run.

The limitations should be another factor regarding whether you get a portable solar generator. Gas-powered generators are reliable, on-demand power (as long as you keep the gas tank filled). Consider the benefits and drawbacks of the solar or gas generator debate.

Types of Portable Solar Generators

Alright, you are considering getting a portable solar generator but are unsure which type to get. Well, there are several different types of portable solar generators on the market. Each of these has its features and benefits. Hopefully, this section helps you decide which is best for you. 

Different Types Of Portable Solar Generators
Solar GeneratorDescription
All-in-one solar generatorsAll-in-one solar generators are like little power stations you can take anywhere. These generators usually come with a built-in battery, solar panels, and different ports and outlets to charge up all your gadgets and gizmos on the go.
Solar BriefcaseThe solar briefcase is a foldable solar panel built into a suitcase. These are super convenient if you’re traveling or camping and need a compact, portable power source. Also, many trade workers, such as electricians, use them on-site.
Solar panels onlyPortable solar panels can be hooked up to a separate battery or power bank. These are great if you already have a battery or want more flexibility in using your solar power. You can just lay the panels out in the sun and let them do their thing.
Foldable panelsFoldable solar panels, similar to the portable ones but foldable. Because they can be folded, taking them with you in your vehicle is convenient, and they do not take up too much space.

What Size Portable Solar Generator Do You Need?

Well, the sizing of a solar generator depends on a few factors, such as:

  • What are you trying to power?
  • How long do you need to power it?
  • What is your budget?

For camping trips, a 300 to 500-watt generator should be fine unless you want to keep your TV running at night while camping. 

If you want to power small appliances at home, such as the lights, TV, Wi-Fi router, and other stuff, try getting a 3000W generator.

However, it will not see you through the night until the morning. So, for anything else, look at getting a 5000W generator. 

Remember that portable solar generators are intended for emergency power situations and should not be considered a primary power source.

Finally, if the generator is used for medical equipment, like an oxygen concentrator, I advise getting the biggest one you can afford.

  5. Keep the generator away from extreme temperatures: Your generator, specifically the batteries, doesn’t like it too hot or cold, so try to keep it somewhere with a moderate temperature. Don’t leave it in a hot car!
  6. Use the right cords and adapters: Ensure you use the right cables and adapters when connecting your devices to the generator. 

There you have it! Follow these simple tips, and you should be able to keep your generator in good working order for a long while.

Are Portable Solar Generators Suitable For Off-Grid Living?

Whether or not a portable solar backup is enough for off-grid living depends on various factors, such as how much power you need, how often you will be using it, and what other sources of energy you have available.

If you are trying to go off the grid, I would advise having a mobile generator as a backup plan.

For example, say your main solar power system is running low, and you need to charge your laptop, watch TV, or anything like that; you can do it.

Also, consider your location and how much sunlight you can access. It may not be enough to meet your energy needs if you live in an area with many cloudy days or long stretches of darkness.
