10 Best Solar Generators

1. Jackery Explorer 1000 Solar Generator

Jackery Explorer 1000 Solar Generator

The Jackery Explorer 1000 has impressive size for the amount of power it provides. Most competitors are much larger, heavier, and pricier compared to what this solar-powered generator has to offer.

With a high capacity of 1002Wh, it meets the power supply needed to power most electrical appliances. It provides a high wattage of 1000 watt rated power and 2000 watt surge.

The Explorer 1000 has two quick-charge USB, two USB-C ports, and three AC standard outlets. Unlike most competitive models, it also has a regulated 12V DC output, which is quite desirable if you want to power any device that cannot work below 12 volts.

When it comes to recharging, it has an MPPT solar charge controller, which is better and achieves faster recharge. Most solar generators come with a PWM solar charge controller, which is less effective. Using two SolarSaga 100W solar panels refills the battery in 8 hours.

When it comes to automatic shutoff, it only shuts off after 12 hours, so if you want to power something overnight, you no longer have to worry about the unit turning off. This solar power station has an LED screen to display the standard statistics on output and battery level. However, it can take up to 20 seconds to show the output wattage for a device after plugging it in. Older models did not have this lag.

Another minor downside is that the 12V DC outlet and USB are combined and powered with the same button. Powering two outlets together might seem convenient, but it does waste power if you are not using both ports. It would have been better if the unit had two separate buttons for this.

2. Bluetti AC200P Portable Solar Generator

Bluetti AC200P Portable Solar Generator

If you’re looking to start harnessing the sun’s power and use sustainable energy, then this is a good place to start. The Bluetti can run high-power equipment for your home, food truck, or off-grid cabin.

How to Choose the Best Solar Powered Generator?

Solar power are quickly and quietly becoming a mainstream way to create green energy. Green energy is cleaner and more reliable than other sources of power. They will save you money and are better for the environment, too. Not to mention, they provide you with super quiet generator power that is suitable for many locations. A solar generator is a machine that captures the sun’s energy using solar panels. Then converts that power into electrical power then stores it in a battery, to be released later through an inverter.

Power stations are commonly referred to as solar generators. This is a bit confusing because they don’t actually generate power through burning fuels like typical generators. Instead, they only store energy delivered from solar panels or household power outlets.

Deciding to buy a solar generator is an excellent choice; however, finding the best portable solar generator is a daunting task. There are so many different kinds, styles, and features that it can seem like a never-ending list of devices that all look nearly the same. Throughout the rest of this article, we will list the key features available in solar generators today. We will tell you what to avoid and give you an idea of the differences between some of the components.

Things to Consider when Choosing a Solar Generator

Some parts can make your solar generator more efficient, while others make it more costly. Choosing the right solar generator is very similar to buying a car; you have a price point in mind, you have a list of features or at least a list of uses, and you’ve done your research.

  • Type of Solar Panels

Three primary kinds of solar panels exist; mono-crystalline, poly-crystalline, and thin-film.

sun power panels for green powered energy
  1. Mono crystalline panels: offers the most quality, and thus are the priciest. Yielding a 15-20 percent efficiency rate, and operating better in high-temp situations are the two biggest benefits of mono-crystalline solar panels.
  2. Poly crystalline panels: comes in second, carries a 13-16 percent efficiency rate, and operates slightly less efficiently in high-temperatures than mono-crystalline panels. The differences between mono-crystalline and poly-crystalline are minimal. The difference in the construction is that mono-crystalline is made from a single crystal. Whereas poly-crystalline is made from many crystals. Poly-crystalline panels are somewhat less expensive than mono-crystalline panels, and are only a bit lower in quality; so they are usually the most popular choice.
  3. Thin film panels: are usually less efficient and less convenient than their crystalline counterparts. Yielding a relatively low-efficiency rate of between 7 and 13 percent. They require a significantly more vast area of coverage to compete with mono or poly-crystalline panels. Thin-film panels are, however, the cheapest option. I believe this is one of the occasions where you truly do get what you pay for as far as quality.

Choose wisely, on which panels fits you best for future convenience.

  • Battery Capacity

Battery capacity is a major deciding factor when choosing a solar generator. When looking at the battery capacity of solar generators, be sure to look for watt-hours (Wh). Because that’s the right battery capacity.

For example, the average iPhone uses about 5.5Wh, and an electric blanket is about 200Wh; if your solar generator only has a 200Wh capacity, you won’t be able to charge your phone and use your blanket at the same time for more than an hour.

Some generators have battery capacities that are perfect for charging your devices during hunting or fishing weekends. But if you want a generator as a backup power supply for your home. You’ll want something that can withstand the high wattage appliances. Then make sure to look for a high watt-hour battery capacity for your solar generator that can withstand your current and future power needs.

  • Inverter Rating

The inverter rating on a solar generator is a number telling you the maximum amount of watts you can pull from the generator at any given time. Depending on your desired use, you may need a solar generator with a larger inverter rating.

However, don’t be fooled; inverter size alone doesn’t influence the power capabilities of solar generators. An inverter of 1500W is useless if it’s being used with a 450Wh battery. The most effective solar generators have a ratio of 1.5:1 watt-hours/inverter rating. For example, a 1500 watt-hour battery to a 1000 watt inverter.

To sum it up, if you intend to use a solar generator to charge a couple of smartphones on a weekend camping trip. A small 200Wh generator will do just fine. Alternately, if you’re hoping to power your coffee machine in the event of a power outage; that size likely won’t be of much use to you.

  • Portability

Many solar generators on the market today combine functionality and practicality; allowing you to have your cake and eat it, too essentially. In any case, you’ll likely find all the features you want and need in a solar generator. Portable enough to easily transport from room to room or lift into a vehicle.

Some of the best portable generators we’ve seen weighed a decent amount but had handles and wheels; allowing for easy transportation, regardless of weight. If you want your solar generator to be as mobile as you are, then you’ll want to look for generators that are either light or have handles and wheels.

  • Extra Features

I wasn’t far off when I compared purchasing a solar generator and buying a car; there are features that you may not “need” but are especially useful to have. There are solar generators with LCD displays, making it much easier to monitor the charge of your device and the remaining battery life of your generator.

Some generators can wirelessly connect to apps on your phone, allowing you to monitor your generator and devices remotely. Also, some generators allow you to expand your power by connecting extra panels when needed.

You can also check our article about how solar power evolved into a reliable source of energy that we know today.

Things to Avoid when Choosing a Solar Generator

setup tools
  • Finally, avoid buying solar generators that have solar panels and battery installed in the same unit – it will shorten the life of your battery due to heat. Batteries hate heat.
  • Avoid making an impulse decision on which solar generator to get; do your research. Solar generators with built-in solar panels are often manufactured in such a way that they cannot be repaired.
  • Solar generator kits, i.e., generator, solar panels, cords, accessories, are more cost-efficient not only upfront but also in the long run because they can be repaired, and the individual parts can be replaced.
  • Watch out for the snake-oil pitch many companies are using to convince people that their generators are the “best”. Avoid spending big money on low-quality solar generators.
  • Purchasing the parts individually or as a kit is almost always the best choice. You get exactly the quality parts you want, and you can also replace or repair those parts as needed.

Setup of a Solar Power Generator

How you set up your solar generator system is very dependent on which solar generator you intend to use and for what purpose. Some solar generators require little or no installation, for use when camping, driving, and backup battery use.

Meanwhile, if you’re aiming at running all the electrical equipment in your luxury RV solely on solar energy. You will have a more in-depth installation process. This includes installing the solar panels on the roof, connecting your panels to the generator, and installing the regulator. As well as, connecting your deep cycle auxiliary battery or batteries and wiring your inverter. In fact, inverters are a necessity if you want to run appliances that use AC power (household); they’re what converts DC power into AC power.

Whether you’re building your system for your home (on-grid), or your mobile vehicle (off-grid); then there are some things you’ll need to know.

Setup of an Off-Grid Solar Generator System

off grid system

A good off-grid setup will give you the opportunity to live without a public electric utility. Whether you’re camping, traveling around the country in your RV, or just want an emergency backup power source.

Once you’ve decided how much power you will need. Having a bank of four deep-cycle batteries and two or three solar panels. You should have no problem meeting your power needs. You also have the option of installing a whole-house solar generator system. One that is able to power an average house, complete with full-sized appliances. But that requires a pretty big budget. There are four primary things that you will need to start your off-grid solar system:

  • Solar Panels

You will need enough solar panels to efficiently charge your batteries, so choosing the right ones is important. Mono-crystalline panels are the most efficient (although the most expensive) choice. Poly-crystalline panels are a little less efficient, but a little less expensive and can do a good job.

Pro tip: Usually, aluminum frame solar panels are more versatile; they last longer, and they also carry a longer warranty than other flexible solar panels.

Warning: Check the warranty carefully when installing solar panels on an RV or other mobile vehicles. As this use is often not covered by warranty.

  • Charge Controller

A charge controller is a voltage regulator; designed to keep the batteries from overcharging. They are almost always a necessary component of nearly all power systems that charge batteries.

Most charge controllers will work with many high voltage solar panels. In order to regulate the maximum total input of voltage not to exceed the capacity. However, using a charge controller will cause a loss of power – from 20% to 60% of what your solar panels are rated at.

A solar panel is only capable of putting out a limited amount of amps. So although the voltage is diminished, the amperage from the panel cannot rise above the rated amps. Therefore, a 175W solar panel, rated at 23 volts or 7.6 amps, will only be able to put 7.6 amps at about 12 volts into the battery.

Pro-tip: Use Ohms Law (watts = volts x amps), to find out how many watts your battery is getting.

  • Battery

A high amp-hour deep cycle battery is the best choice for off-grid or strictly solar recharge use. A deep-cycle battery is designed to be able to regularly deeply discharge; meaning using most of its capacity. High power usage appliances mean a shorter life per charge. So if you want to use your solar system without worrying about every light being on or off. You will need a high amp-hour (Ah) battery. Battery options include lithium batteries, which are the most expensive. Or lead-acid batteries, which are still high quality and more affordable.

  • Inverter

An inverter is a great thing to have in a portable solar system. Because you won’t have to worry about finding a 12V charger or device while traveling. As well it produces sine wave energy that is safe to use with sensitive electronic devices and appliances, such as mobile devices. A 2000W inverter is a good choice; it will run almost anything, except an air conditioner.

  • Installing of Solar Panels

Which position to set your solar panels can be a little tricky. Because you will want to generate as much power as you can during the daylight hours. When positioning your solar panels, be sure to place them facing south (if possible), and angle them at about 30 degrees. This will give you optimum efficiency throughout the year. If you live in a house that only has East and West facing rooftops. You can install solar panels on both; allowing you to get maximum coverage throughout the day.

Setup of an On-Grid Solar Generator System

on grid system

An on-grid setup is very simple. You simply install a solar panel(s) on your roof or in your yard. Then connect them to a grid inverter. Then connect the inverter to your existing electrical network. This is a great way to reduce your electric bill, as well as go green using renewable energy. Allowing it to serve as a standby generator.

Pro-tip: A great option would be to install as many solar panels as you can within your budget. Then simply wire the panels into a micro-inverter, and plug the inverter into any standard 3-pin plug in your home. Power will always take the shortest route; therefore, your appliances will use the available solar power before any power from the grid. However, remember that you will need an inverter or charge controller system to convert all the solar panels to household 120V/60Hz before plugging the solar arrangement into your electrical system.

Bottom Line

  1. Thank you for this very useful article! Would you recommend a solar generator (instead of a regular solar kit with solar panels on the roof) for a kinda nomadic couple? 🙂 We’re moving to an small house in the middle of nowhere, but the deal is to leave the house in two years. That’s why we’re thinking about portable solar generators or kits.
    Do you think that a portable generator (1200 Wh or more) is suitable for a daily use at home?

    Thank you so much from Spain!

    • The new Goal Zero Yeti 1400 Lithium would be a perfect fit, it has 1425WH. All you would need with these solar generators is to connect them to solar panels. And you can also charge them through a wall outlet, but definitely a solar panel is the way to go.
      We are very happy that we could help, thank you

  2. Hi
    As you are a 3rd party expert I want to confirm my assumption with you. I want the most powerful, efficient and safe solar powered generator. After much research it seems that the Goal Zero Yeti 3000 is the highest wattage most efficient solar powered generator. Based on your expertise can you tell me if I am right or if there is a more powerful higher watt solar generator out there? At a cost of $3,000 I just need someone to tell me if I making the right decision for the type of generator I am looking for and it seems you can help me, I hope. Thank you, Robert

    • That is true Goal Zero Yeti 3000 has the highest rated wattage. If you are looking for more power then the other option would be to purchase separate batteries, charge controller, and solar panels and make your own off grid solar system.

  3. This is a fantastic article and really well put together. I have been doing my normal obsessed approach to research regarding solar over the past several months and I’m blown away at how far we have come. In addition, how affordable these systems have become. And like usual I’m jumping in feet first and very excited. The parts are being delivered as we speak. 700watts of solar panels on the roof of the RV, 100amp MPPT solar charger, 3000 watt inverter and all directly wired into my 12volt panel. This will fundamentally change the recreational vehicle industry. The option on where we can go are unlimited. Sorry, got a little side track. Back to the generators I thought a solar generator would be a good compliment to my system and like you have indicated, it can get very confusing. I think I’m going for the ECOFLOW, I like the solar panel recharge number assuming if I double the panel to 100 watts I can cut that time in half. But I will need to look at that port and see what’s the capacity. thanks again Geoff

  4. I think the best one is GOAL ZERO YETI 1400 because it has many features. The second which I will prefer is JACKERY EXPLORER 500. Thank you for sharing this information.
