Buyers Guide: How To Choose
The Best Solar Generator
Think about this for a moment…
What can be purer than the energizing rays of the sun?
Using these rays to generate safe and renewable power is one of the best eco-friendly choices you can make.
On top of that, there are the low maintenance costs and silent operation.
Having a “green” solar panel generator as a backup for your home or for camping trips is definitely the smart step to take.
But then you start to worry about what to look for when making the perfect choice.
The good news for you is, we’ve listed all the important points to consider when buying a solar generator, right here.
So, before you choose yours, here’s everything you need to know about them.
What Are The Different Types Of Solar Generators?
From an operational point of view, they can be classified into three types. Let’s take a look:
- On-grid solar systems – This is a solar generating system that has no battery but is connected to the power grid of a country or a region. The panels generate DC current by making use of photovoltaic effect. This DC current is converted to AC through solar inverters and can be used in homes.
- Off-grid solar systems – These units aren’t connected to the grid. So apart from the panels, it needs an inverter and a battery bank for storing the electricity. They’re good choices during emergencies or when you head off-grid. The best small portable battery generators are modified off-grid units.
- Hybrid systems – These systems use a battery and a battery inverter while also being connected to the grid. So, they can store any excess energy generated. This is less costly than an off-grid system and can make use of any excess solar power without wastage.
Features To Look Out For
Here’s our list of the most important aspects:
- The first step is to decide your own power requirements. The low capacity generators ranging from 300 to 400-watt hours can be used for charging laptops or mobile phones. If you have a higher power requirement, choose a model that can deliver between 1400 to 1500-watt hours.
- Solar generators are often designed to suit specific activities. While some are for use in your home, others are more suited for outdoor activities liking camping or hiking. A degree of portability is essential for any model. However, models with a higher battery capacity are usually on the heavier side. Note, you’ll also need to carry the solar panels along with the generator.
- While a solar generator is designed to generate power from the sun, it’d be a good idea to have a backup system in place in case of bad weather. Many manufacturers provide additional options for recharging the batteries. This can include connecting with a car battery or plugging it into a wall socket.
- The solar panels needed to charge your generator are no less important. It’s best to choose a model that’ll allow enough flexibility to increase the number of panels in the future. If you buy panels with higher efficiency, the generator will charge faster. However, make sure not to overload it and stick to the specifications.
Product & Specifications Explained
Manufacturers use specifications for solar generators which many of us may not be aware of.
Here are some of the important ones for your reference:
- Like oil generators, solar ones also have a ‘Continuous’ and a ‘Surge’ rating. The Continuous Rating is the amount of power in Watts the generator can supply steadily for long periods. The Surge or Maximum Rating is the power it can supply for brief intervals and that very much depends on the product. This excess power is often needed to cover the starting load for larger electrical items.
- Note that many solar generators are equipped with a pure sine wave inverter. AC current generates a continuous sine wave that’s characterized by a smooth and repetitive oscillation. A smooth and rounded sine wave signifies low harmonic distortions which help in preserving the life of sensitive electronic products.
- By now you may have noticed the battery capacity of any solar inverter generator is measured in Watt-hours (Wh). This is the product of the voltage of the battery and the current (in Amps) it produces in a given time. The current produced in hours is represented by Ah or mAh.
Things To Consider
When you buy a solar powered generator you’ll be looking for great long term performance. So it’s worth making notes on a few important aspects to consider when you make your buying decision.
To start with, you need to decide on the storage capacity of the battery. Keep in mind that while batteries are rated in amp-hours, the appliances are rated in watt-hours. So you need to convert – so as to rate the battery accurately.
Here’s an example:
A 12v 120amp/hr battery will be rated 2400w/hr. This is done by simply multiplying the amp/hr value with the volts.
Battery manufacturers recommend regularly using 2/3rd of a battery’s full capacity to preserve its life
Next, consider the solar panels you’ll use if the generator doesn’t have inbuilt panels. The capacity of the panel is measured by the number of watts it generates. Remember the panel will deliver full power only when the sun is at the peak and the rays fall directly on the panel surface.
Finally, check the quality of the components of your chosen generator. A solar power generator that’s able to withstand tough outdoor conditions and comes with a long warranty is a great place to start. High-quality metal casings ensure the unit will be sufficiently durable. If the product comes with wheels, make sure they’re built to last.
At times, technical terms can be daunting. Here’s a TopNotch guide to the jargon related to solar generators.
Power Capacity & Capability
The power storage capacity of a battery in a solar powered generator is measured in watt-hours (Wh). It’s the product of the battery voltage into the current – in amperes, it delivers in an hour. Since the voltage is fixed for most batteries, the ampere delivered per hour is most important. It’s designated by Ah or mAh (1000mAh = 1Ah).
On the other hand, the power capability (C) is the ampere-hour value divided by one hour. In the case of a 2Ah battery, the value of C is 2A. Note that a battery with a high value of C will allow you to draw more current from it without getting exhausted.
The main function of a solar panel is to capture solar energy and convert it into electricity. These panels consist of multiple solar cells that use photovoltaic effect to convert light into current. You’ll find these panels can be monocrystalline solar or polycrystalline. While the former uses a solar cell made from single silicon crystals, the latter use cells made from multiple silicon particles fused together.
The Absorbent Glass Mat (AGM) battery is a special lead-acid battery that’s lightweight and highly efficient. The most important feature is the use of a fiberglass mat that absorbs the generated sulphuric acid, reducing the chances of spillage. This makes the battery suitable for use in places where there’s a restriction on hazardous materials. Apart from that, these batteries can deliver higher currents and they have a longer life.
Basically, an inverter in a solar generator converts DC current into AC – most commonly used in household appliances. Most of the modern inverters use oscillator circuits to do this. Since AC current forms a sine wave, high-quality inverters also have filters that make the wave smoother and more round. This makes the current safe enough for sensitive electronic equipment.
TopNotch Top Tips
Time to take a look at our tips for buying the best solar generator.
- The first step is to know exactly what you need. Once you know, you’ll have a fighting chance of making sure your brand new generator has the power you need.
- I have to tell you – knowledge is a vital key. To pick the best product, you have to learn about how they function. For this, you need to study how a panel works and its main features. This will also help you understand any shortcomings. Even after selecting a generator, you’ll need to choose a TopNotch solar panel that’ll work smoothly with your generator.
- Transportability of your solar powered generator is another factor you can’t ignore. You may need to carry it around the house or use it for a weekend trip in your RV. So, a lightweight product with a well-designed carrying handle are two features to look for.
- We’d also advise you to keep realistic expectations of your solar generator depending on your budget. Most solar generators are ideal for small electronic products and some may support larger equipment for short periods.
Frequently Asked Questions
Q: What’s the best solar generator to buy?
A: The best solar generator is the one that meets your needs and suits your budget. Just make sure to consider the nature of your use and the amount of power you need. Do keep in mind our TopNotch top tips.
We’ve marked our three top choices at the beginning and end of this review. But all 10 are top-rated products on the market.
Q: Can a 100-watt solar panel run a refrigerator?
A: The answer requires some calculation. In theory, the power consumption of a refrigerator depends on its capacity, the amount of food stored, and how old it is. A refrigerator can use between 100 to 500 Watts depending on these factors. There is also the requirement of surge power during start which is much higher.
You also need to consider how many watt-hours the panel will be able to generate depending on the daily availability of sunshine. That energy needs to be stored in a battery to make a portable solar generator kit. So unless you’re using the 100 W solar panel to charge a large capacity battery of around 1400 Watts, you will not be able to run a refrigerator.
Q. Is there a generator that runs on solar power?
A: Yes, there is.
Basically, a solar generator converts solar energy into electrical energy through solar panels. In addition, they also contain a battery charger or solar charge controller that regulates the current flow from the panels to the battery in a safe manner. The energy is stored in portable batteries that can be used to run a wide range of appliances.
Note that quite a few of the top models that we’ve reviewed don’t come with their own solar panels. But you can always charge them from an AC outlet or even from your car battery if needs be.
That covers it …
You’re now ready with all the necessary details to choose the best solar generator.
And the results of the tests are listed in the next section where we give you comparisons of the various products…
Our Analysis, Comparisons & Test Results
Value For Money
Think about this for a moment
The concept of value is not exactly linear. Moreover, that which constitutes value for one person, may not be the same for another.
So while evaluating the best solar generators under this metric we not only considered the price tag but also the overall performance.
Value For Money Rating
To do this we needed a thorough analysis – along with a few more drinks
…But as a result, we found exactly how the competitors stand against each other.
The Renogy Phoenix solar generator scored top marks in terms of price versus performance. The combination of ease of use and the inbuilt solar panel makes this solar generator stand at the top of the chart.
Next, four other models are placed jointly in the second spot – the Jackery 240, the Coolis 150Wh, and the Goal Zero Yeti 400.
Even though they’re priced quite highly, superior power delivery makes them an invaluable emergency power source.
The fact is, we loved using the Goal Zero Yeti 1400.
The Suaoki 400Wh and the Yeti 150 are great choices for outdoor use but you need to consider the fact that you’ll need to buy the solar panels separately.
Lastly, given the low power output, the Suaoki 150Wh solar inverter generator had the lowest marks in this metric.
Most compact and portable solar generators don’t have sufficient power output to run large appliances.
At the same time, to buy a high powered unit, you’ll have to pay much more.
While evaluating these products, we looked at the Watt-hours of each battery.
Output Power Rating
The battery voltage changes as it gets drained and the amp-hour of mAh depends on the voltage. But the Watt-hour number remains stable at all times.
The Goal Zero Yeti 1400 occupies the top spot with its high continuous power output and a surge power output of 3000 Watts.
Longing for a solar generator that can charge your refrigerator or LCD TV for hours? In that case, this is definitely one of the best solar generators to choose.
Up next, the Yeti 400 and the Suaoki 400Wh come with their moderate capacities. Perfect choices for charging up all your electronic devices on a camping trip.
The Jackery 240 and the Renogy Phoenix share the same spot as they’re almost equal in terms of power delivery.
Lastly, we have our four models that score the lowest in overall power delivery.
Having said that, in case you need a small solar generator just to power up your mobile phone, iPad, or camera, they’re very competent choices.
The durability and design of a product are factors that affect your user experience in a major way.
No doubt about that.
Keeping that in mind, we paid special attention to the overall design, especially while choosing a solar powered generator for camping. In addition, we also noted the ergonomics and the warranty with each product.
Durability/ Workmanship Rating
Beyond that, we took the feedback from long term owners – a practice we follow for every TopNotch product comparison.
So how did the generators fare?
Let’s take a look.
To start with, the Goal Zero Yeti 1400 came in at the top of this metric, as its design promises a long lifespan. We also liked the fact that it’s able to function efficiently at extremely low temperatures.
Standing in the second spot are the Paxcess and the Coolis.
And you know what?
Apart from being well-built they also come with a couple of unique features.
While the Paxcess 100 W is IATA approved and ready for air travel, the Coolis generator comes with a protection film for the LED screen.
In the same category, the Audew solar generator has a durable aluminum outer shell that’s corrosion-proof.
The next four competitors including the two models from Suaoki fare equally well in terms of overall durability.
Don’t get me wrong. They’re all well-built generators but just don’t expect them to withstand too much rough handling or extreme conditions.
Now you must be wondering about the two Goal Zero models that come last.
Considering the price of these two solar generators, we felt they should come with a longer warranty period than the 1-year period being offered.
Dependability is a prime factor if you need power when you’re heading for an off-grid location or during an outage in your home.
Here’s another great advantage of solar generators. The fact that they need a lot less maintenance sets them apart from their oil-driven counterparts.
The only thing you need to do is discharge and recharge once every three to four months.
Dependability/ Reliability Rating
Sounds simple. Right?
Frankly, judging these top-grade products under this metric wasn’t an easy task. The strengths and weaknesses of each generator were very evenly matched.
But we went through the pros and cons of each product and the results are listed below for you.
The Yeti 1400 proved its superiority in this metric with a flawless performance.
In fact, we couldn’t find anything that could affect its reliability.
After a lot of analysis, we gave the next five solar generators the same marks in this metric.
Whether you solar generator for cpap or for your RV, these models will deliver a TopNotch performance.
The Renogy Phoenix comes with a 20 W solar cell but to make it perform efficiently, more cells are needed.
The Goal Zero Yeti 150 and the Suaoki 400Wh stood at the lower end of the chart.
At 12 pounds, we found the power to weight ratio of the Yeti 150 on the lower side.
The Suaoki 400Wh and the Audew 220Wh got low marks as they can’t be used while being charged.
All solar generators are supposed to be noise-free. Right?
It’s true these models are miles ahead when compared to any gas-powered generator in terms of noise.
For any campsite with restrictions on noise pollution, these models are a great choice.
To tell you the truth, after testing the whole range of camping generators on our last review trip, we really loved the silence these solar power generators delivered.
However, there are some minor differences between them that our team noted during the testing sessions.
So let’s take a look at the details.
Perhaps unsurprisingly, we have three solar generators at the top spot under this metric.
We knew that the Yeti 1400 and the Jackery 240 are two products that have a great reputation on the noise front.
After our tests, we found the Yeti 400 offering similar levels of noise-free performance.
Even during the night, we found no noise from these products despite being connected to multiple devices.
On the other hand, the Suaoki 150Wh and the Yeti 150 were not as quiet but still impressive. We felt the use of a lead-acid battery in the Yeti 150 makes it slightly noisier.
The Coolis 150Wh, the Suaoki 400Wh, and the Renogy Phoenix were rated equally when it came to noise. We did notice some noise while charging AC devices like small fans.
To be fair, the noise levels were within acceptable limits.
Lastly, the Audew 220Wh battery generator turned out to be the noisiest among the lot. It made some noises while charging up and also during discharging at full loads.
