What is a Solar Generator

When people talk about solar generators, they typically refer to a portable power system that uses solar panels to produce electricity stored in a battery for later use.

Solar-powered generators are often used in RV’s, boats, and backup sources of power for grid outages.

How Do Solar Powered Generators Work?

There are a few basic steps and components used in a common solar-powered generator.

  1. Solar panels attached to the generator collect and convert sunlight to Direct Current (DC Energy).
  2. The DC is passed through a charge controller, which controls the voltage of the energy going to the battery to be stored for later use.
  3. Once the energy in the battery is needed, it passes through an inverter that converts it to Alternating Current Energy (AC).

Most portable solar generators have AC Outlets, USB Ports, and 12 Volt Carports. This allows you to charge multiple devices or small appliances.

How Much Power Will My Generator Provide

This, of course, depends on the size of your generator and how long the sun is shining – meaning how long the battery is allowed to charge.

Battery storage is also important. Convert your amp hours to watt-hours and make sure you have the storage to meet your needs. Add 3 days for those cloudy days.

Example

To get watt-hours from amp hours, multiply amps times volts. The watt-hour rating for a 12-volt 100 amp/hr. battery is 1200 watt-hours.

Take a look a the following appliances.

  • Light Bulb = 60Wh
  • Refridgerator = 900Wh
  • Cell Phone = 40Wh

If you anticipate you will use 1,000 watt-hours each day, multiply this times 3 and you will need batteries to store at least 3,000 watt-hours.

Advantages & Disadvantages

Like any power source, solar-powered generators have their advantages and disadvantages. Before you say NO, it is too expensive, consider this.

They may be heavy, and they may be expensive, but they are probably going to last you 20-25 years, and when all other fuel is gone, you can sit this bad boy out in the sun and turn on the lights!

Advantages

  • Quiet – Nice when camping in the backcountry or wilderness.
  • Clean Energy – no smelly or expensive fuels and pollutants.
  • Less maintenance – there are not a lot of moving parts.
  • Life expectancy – 20 to 25 years!

Disadvantages

  • Price is currently high, but as they become more popular and technology advances, prices will come down.
  • Slow to Charge – they can take all day and are much slower than gas generators.
  • Power Supply – they depend on the sun being out. Battery size is important.

Additional Tips to Consider When Purchasing

If you are thinking about purchasing a portable solar generator, there are a few additional things you should keep in mind.

  • Inverters – Make sure your inverter is a Pure Sine Wave Inverter. This is the type of AC electricity your appliances and electronics use.
  • Most solar-powered generators include a charger, inverter, and battery. They do not often include solar panels unless you purchase a kit.
  • Batteries – make sure you have the right size and type of battery.
  • Recharging times should be reasonable, especially in the winter or with volatile weather.
  • MPPT Charge Controllers are more efficient. Keep in mind they are not 100% efficient.
  • The charge controller determines how many solar panels you can add. Make sure the voltage input is not too narrow.

Best Solar Powered Generators

There are a lot of choices when it comes to solar-powered generators. I’ve read reviews, consumer reports, articles, and reviewed comments on manufacturing websites.

Based on consumer feedback, these are currently four of the best generators available at a reasonable price in both the small and mid-size categories. All of the generators below receive 4.5 – 5 stars and have hundreds or thousands of reviews.

Small Portable Solar Generators (100W – 600W)

My favorite generator in the small group is the AIMTOM. It provides exactly what I need to run small tools and electronics if I’m off-grid or on an overnight camping trip. Its 3x USB ports, 1x DC outlets, and 3x AC outlet give me the versatility to power what I need.

My second choice is the 240W Jackery. Jackery has good reviews and is a solid generator to keep everyone’s devices powered up when we are camping. This is also a great entry-level generator for camp @ only 6.6 pounds.

Mid-size Portable Solar Generators (1,000W – 2,000W)

You really can’t go wrong with any of the generators in this list, but I’ve always been a Bluetti fan. Jackery runs a close second, but the number of input and output ports/outlets provided by Bluetti is almost double that of Jackery.

Jackery takes the award for ease of use, but if I had to go with a runner-up it would probably be EF Ecoflow @ 1800W. The drawback is its lack of outlets, so you really have to decide what you are going to use your generator for – a true backup power source or keeping everyone on their handheld devices around camp.

Solar Powered Generator Bundles (With Solar Panels)

Many of the solar-powered generators come packaged as “bundles.” The “bundle” typically includes solar panels, and if you purchase them together, you get a discount versus buying them separately.

I’ve listed some of the bundles below. Before purchasing separate panels with your portable solar generator, though, check the manufacturer warranty. In some cases, you may find that they don’t guarantee the generator if you don’t use their panels.

Portable Solar Generators – Final Thoughts

All of the solar generators I have listed are well-made and will provide you with the power you need when you need it.

Personally, I would charge them with solar panels, and you will be surprised at how quickly they can be charged if you string panels together.

If you are setting up one of the larger generators in camp, you can set the generator up during the day and have it fully charged and ready to power up your appliances and devices when you return at the end of the day.

  • The portable solar generator is my best friend during storms. I have the KISAE 40402 1800-Watt power kit; it is amazing. One time during a storm, I used it to power the heater and keep the house warm in the cold weather, I also used it for cooking when the power was out. It continued to run even after the storm. I need another one for my office.

  • I got the Yeti 400 solar generator kit; it has everything I’ve been looking for in such a device. I usually charge it through AC during the night, and sometimes through the sun. The next morning it charges my iPhone and iPad in a short time. The display is easy to use and understand; it stays lit as long as I need. In fact, this was my first solar energy device I bought and I’m impressed with the results.

  • I own both the Sunforce 50048 60W Solar charging kit and the Wagan EL 2546 Solar e-Cube 1500. Personally, I haven’t had any problems while operating them, but I can’t tell you which one is the best because I haven’t used any other model. If you just want to keep small items, like a GPS or a smartphone, charged up, the Sunforce is great and is relatively compact and rugged.

  • I need a little help here. I am a simple girl who cannot live without my iphone with me, and I am about to leave for a hike this coming month. I am in search for a portable solar generator that can speed up my phone charging. In fact, I have tried buying one, but it is an epic fail. The advertisement said that it’s a 2A/2A+ outputs, but it hardly reach 2 amps. Do you have any recommendations for me?

  • We have presented you with some of the best camping/emergency portable generators, but you can always settle for smaller and ultra-lightweight solar chargers, such as the battery pack AKEEM portable charger or the Nektec 20W Solar charger.

  • Thanks for presenting to us some of the best portable generators in town. I have been thinking of purchasing one for my grandfather’s farm; it is about 10-11 acres. The area is somewhat far from the city; thus, my grandfather wanted to buy long lasting portable solar generators to suffice the needs of the farm. How many years could this type of generators possibly last?

  • With typical usage and proper maintenance of a portable generator, it should be able to serve you for more than ten years. There are some that can last 30+ years.
