The solar power generation is the system in which solar panels convert the sunlight into the electric energy to run multiple devices. As the advancements and new technologies are entering the market after every few months, we have a lot of solar generators inexpensively available out there today. Most importantly people these days commonly use portable solar power generators as they can take them during the journey, camping, hiking, etc.
Working Principle of Portable Solar Generator
Typically, a portable solar generator comes with two layers of photovoltaic cells on each side of the lids of a suitcase-style product. Once you place these layers in the sunlight, they produce an electric field which results in storing the electric energy in the battery of the device. Yes, it packs the battery and other components inside the case. Below is an example of a typical suitcase solar generator.

Of course, the portable solar power generators are similar to the residential and commercial solar power solutions, except for certain features, such as carrying case, kickstand, foldable design, etc. Moreover, they also need some additional devices like the inverter and charge controller so that you can use it as your regular power tool.
Portable Solar Power Generators – Buying Guide
If you have a plan to buy a portable solar power generator for yourself, then before you buy the wrong one in a rush, make sure you do your research for important things that you must consider beforehand.
1. Type of Solar Cells
Commonly, we have three types of solar panels in portable solar generators on the market. These include the monocrystalline, polycrystalline and thin-film solar power generators. Let us explore each type in detail below.
Monocrystalline Portable Solar Power Generators
The monocrystalline solar power generators are very expensive, but due to their high-efficiency, many people prefer to use them. In order to form their solar cells, the manufacturers use high purity silicon. Due to their use, the portable solar power generators become 20 percent more performant than the conventional solar power generators, and they are also more durable.
Polycrystalline Portable Solar Power Generators
Their blue color identifies the polycrystalline solar panels. As compared to the monocrystalline solar generators, the polycrystalline solar generators are less efficient. It is because you have them built with the melting fragments of silicon. They are available at very affordable prices which is why people like to use them if they want a very small portable solar power generator.
Thin Film Panels
The thin-film solar panels are, in fact, known as the best solutions for the solar power generators, because they are very light in weight, and they have a foldable design. You can even roll some of the thin-film solar panels. Moreover, their installation is also very easy. The only flaw is that they are not as efficient as monocrystalline portable solar power generators.
2. Energy Generation Capability
The amount of energy that a portable solar power generator could generate depends on different factors. These factors may include the efficiency of the generator, the size, and weight of the generator and its exposure to the amount and intensity of sunlight energy.
Mostly, the solar power generators available in the market have power between 210 to 350 watts. However, this amount of output happens only in ideal conditions that rarely exist in nature.
Therefore, you can only use it as a reference to calculate the performance of your device. You can choose the one that is highly efficient and is capable to produce energy as much closer to these ideal portable solar power generators.
In an average home, almost around 30W of energy is quite enough to run all essential appliances. Thus, using a portable solar power generator, you will be able to save almost 10 to 20 percent of your electricity bills as you can run all your small appliances with the solar power generator.
3. Evaluate the Components of Solar Power Generator
Another thing which is very important to evaluate when you choose a solar power generator is its components. According to the working and efficiency of solar power generators, they have different components. Among these components, the battery and inverter are the important components that one must look for very careful while buying.
The battery must be of good quality and must not deplete charging when you are not using it. If you want a single panel, then the 12-volt battery is enough, otherwise, buy the one with multiple panels and high voltage battery.
Yes, you store the energy in the battery as the direct power. And with the help of an inverter, your device turns it into the alternate current power. That is, you must carefully choose a solar generator with a good inverter because that is what offers the real efficiency of your solar power system.
4. Understanding of Solar Power Specs
- It is very important that a person consider the specs while choosing the portable solar power generator. These include:
- High module efficiency of solar power generator because it will help you evaluate how the solar power generator will perform under ideal conditions.
- Find out the total number of solar cells of which a particular solar power generator is made.
- Check the generator performance when the solar light is very low or dim.
- The frame of the solar panel is also important because it will make sure that how protected it will be under high wind speed and snow falling conditions.
- If you are going to use the portable solar power generator at your camp near the ocean, the check its resistance against salts and ammonia.
- Check out the warranty time duration of your chosen power generator.
- Consider the dimensions and weight of the generator according to your requirements.
- The power rating is another important spec to note. One must evaluate the voltage of generator at maximum power, the amount of ampere at which it gives maximum output, etc.
- It must fulfill all the safety standards of IEC61730 and also make sure that it is capable of bearing any kind of outside weather conditions.
- It must also cover the safety standards of ISO so that you can use it safely in the outdoors.
- The last thing to consider the version of your portable slaw power generator. It is important because many times the older versions are not very good performers so keep that in mind and try to buy the latest version.
5. Place Portable Solar Power Generator Use
The use of a portable solar power generator is most common in the USA where the electricity rates are very high; the best Dallas electricity rates can easily be obtained through companies that provide low rate plans for the users.
In such cities, people like to take advantage of the natural renewable resource of sunlight to fulfill their electricity needs.
The power output of portable solar power generators depends on the season, and they vary in each season. Even in the same season, due to changes in the shade and exposure to sunlight create differences in their output power.
So, when you are choosing your solar generator, keep in mind the place you are living and how much exposure to sunlight you will have at that place. It should be easily installable, adjustable and could be oriented easily.
6. Charging of Portable Solar Power Generators
Charging of portable solar power generators is very important. It must be very efficient because it is the main thing that tells about the quality of a portable solar power generator. There are many solar power generators that can be charged with few hours when exposed to high-intensity sunlight and even under dim light.
Different brands and models of solar power generators are available with different battery timings. All of them are charged with different timing, so their battery timings are also different. Now, you have to choose the one that is suitable according to your needs at a certain place. If you can afford to charge it in a longer time, then buy the own with this property.
7. Assess Your Needs
You have first to decide the amount of power you need while camping or during your whole trip. Also, if you want to use the portable solar power generator at home, then make a list of appliances you want to power with it. If, for instance, you have a solar generator with 12 voltage battery, then you can easily power a small fridge and a camping cooler with it. If the appliances are large, then chose the solar power generator with a high voltage battery.
You also have to consider the fact that if you will be able to rely on a single small solar power generator or not. If no, then look either for the bigger one or take 2 to 3 small solar power generators with you.
The portable solar power generators are very comfortable for use, and they cut down your electricity cost at home. Also, you will be able to take care of the environment by using sunlight energy as a source to charge your cell phone and run your appliances at home. You have to just take care of the type of panel you’re going to buy according to your needs and their work efficiency so that you may not need to change it again and again.
