How to Choose the Best Solar Powered Generator?

Solar generators are quickly and quietly becoming a mainstream way to create green energy. Green energy is cleaner and more reliable than other sources of power; will save you money and better for the environment, too. 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.

Deciding to buy a solar generator is a fine 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’ll list the key features available in solar generators today, what to avoid, and give you an idea of the differences between some of the components.

Things to Consider when Choosing a Solar Powered 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.

solar panels

  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, yielding a 13-16 percent efficiency rate, and operating slightly less efficiently in high-temp situations than mono-crystalline panels. The differences between mono-crystalline and poly-crystalline are minimal. The difference in manufacture is mono-crystalline is made from one crystal, whereas poly-crystalline is made from many. Poly-crystalline panels are a bit less expensive, and only slightly lower in quality than mono-crystalline panels; so they are typically 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 ideal for charging your devices on a weekend camping trip. But if you want a generator as a backup power supply for you home, you’ll want something that can withstand the high wattage appliances. Be sure to get a solar generator with a high enough watt-hour battery capacity for whatever your needs may be.

  • 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.

But don’t be fooled; inverter size alone doesn’t determine a solar generators capabilities. A 1500W inverter will do you no good if it’s being used with a 450Wh battery. The best and most usable solar generators have at least a 1.5:1 ratio of watt-hours/inverter rating ratio – i.e., 1500Wh battery to a 1000W inverter.

To sum it up, if you intend to use a solar generator to charge a couple of cell phones on a weekend camping trip, a small 200Wh generator will do just fine. Alternately, if you’re hoping to power your sump pump 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.

Things to Avoid when Choosing a Solar Powered Generator

solar generator tools

  • Finally, avoid buying solar generators that have the 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 Powered Generator

How you set up your solar generator system is very dependent on which solar generator you’re intending 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 on 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, wiring your panels to your generator, installing the regulator, as well as placing your deep cycle auxiliary battery or batteries and installing your inverter. In fact, inverters are a necessary if you want to use AC (household) appliances; 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), there are some things you’ll need to know.

Setup of an Off-Grid Solar Generator System

off grid solar system

A good off-grid setup will allow you to live without a public electric utility. Whether you’re traveling cross-country in your RV, camping, 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 huge 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: Aluminum frame solar panels last longer, are more versatile, and carry a longer warranty than 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, regulating the maximum total input of voltage to not 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 solar 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.

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. This is a great way to reduce your electric bill, as well as go green using renewable energy.

5 Advantages of Owning a Solar Powered Generator

Whether you have decided to become more eco-friendly, are looking for a less dangerous backup power source to replace your fuel-powered generator, or you want to go off-grid; there are many benefits, and no foreseeable downsides, to owning a solar powered generator. In fact, there are too many benefits to list in one article; so here are 5 great advantages of owning a solar generator.

green energy life symbol

  1. Eco-Friendly

The average 5 person, 2 car family produces 58,109lbs of CO2 per year. As a matter of fact, by using solar power to run your home just 25% of the time, you can decrease your households’ CO2 output by nearly 6% per year. That’s the equivalent of 175 gallons of gas.

  1. Investment in Long-Term Savings

Using solar energy just 25% of the time can save you as much, or more, than 400$ a year. Moreover, that’s if the only energy-saving action you take is using solar power. Therefore, no matter how much your home solar generator system costs, it will save you money over time. Everyone likes the idea of saving money.

  1. Great for Indoor Use

As opposed to gas powered generators, solar generators are unbelievably convenient for use indoors due to them not using fuel. Producing no toxic fumes, consequently, solar generators are completely safe for use indoors. No moving parts is another great safety feature. Being able to use your backup power source indoors is significantly more convenient in a power outage situation; rather having to gas up and maneuver a gas generator outside in the dark. You can easily transport your solar generator from room to room in the safety and warmth of your own home.

  1. Noiseless Operation

Not only is it easy to use indoors it’s also a silent generator; many campgrounds have a quiet time or noise regulation, as a result effectively limiting the usefulness of many fuel powered generators. Charging your camera, or flashlight in the middle of the night isn’t going to work if you can’t run your generator. Most gas powered generators range from 50 to 85 decibels (dB) of noise. Every 10 decibels is about 10 times louder to the human ear. Therefore, making an 80-decibel noise rating nearly unbearable.

  1. Ease of Use and Convenience

Lastly, once a generator is properly installed and or set up, it will run 24/7 with no maintenance from you. During the day, the sun’s rays will charge your battery, and at night the battery powers your electronic devices. For as long as there’s enough sunlight during the day, you’ll never have to worry about your solar generator. If you’ve ever used a gas-powered generator, you know that between changing the oil, managing the gas, and in addition to making sure it’s not being too loud for anyone around, you’re perfectly aware of the many inconveniences a gas powered generator can have. However, that’s not to say that gas generators don’t have a good use, but in many cases, the benefits of a solar generator greatly outweigh the benefits of a fuel generator.

Bottom Line

Choosing to own a solar generator, whether for home or travel, is a great choice. Furthermore, it can and will save you money, and it will also make emergency power outages, long camping trips and cross-country RVing easier, more convenient and more fun. With so many brands and options, not to mention conflicting or absent information, it’s hard to make an educated and informed decision about a product. We brought you solar generator reviews and guide to make your search for the best solar generator a little easier. Whether you were trying to figure out the difference between solar panels, or you wanted to know what an inverter is, we hope we covered all the information you would need to make an informed decision.
