How much power can a portable solar panel generate?

Would you like to have a renewable energy source to supply you with electricity? Whether it is to help in the event of a power outage or to accompany you on your hikes, solar generators are an excellent option. So, before you start, you want to know what power is generated by a portable solar panel, its mode of operation or the expected budget, keep reading.

Store solar energy

It is possible to store the sun’s energy. With only a portable solar generator and a solar panel set with battery, it becomes a breeze to drive your outdoor trip or your home in the event of a power outage.

This type of power generator offers one maximum security and can therefore be used without fear indoors. Unlike gas generators, solar generators supply electricity without exhaust fumes or noise. This clean and renewable energy can be used at any time. Let’s take a closer look at how it works.

The solar panels are foldable and can be worn and placed anywhere. Once on earth, they will collect sunlight to convert it into usable energy. To save this energy, they use a solar generator. This will convert DC to AC so that its users can operate any device. The portable solar generator contains various essential elements:

  • One or more solar panels : Thanks to their photovoltaic cells, the panels will capture solar energy. These are foldable for easy transport.
  • A battery : When in lithium, the battery is stronger and lighter. Again, this is an important point for a portable generator.
  • Cables : Generally supplied with the generator, they are essential for the generator to work properly. As a precaution, you can order spare cables in the event of a problem right now.

The generator therefore alone plays the role of a battery and a solar inverter. It is an effective solution when you are in situations that cut you off from the public network. Whether you are camping, by the sea, in the mountains or in a country house that is not connected to the local electricity network, this tool will easily operate your electronics and household appliances.

How to choose a portable solar generator?

To find the perfect generator, tailored to your needs, it is important to check everything in detail. It exists 4 main points to be inspected, namely:

The power

The amount of power supplied by the generator should be determined by your needs. Must therefore calculate the consumption of your appliances. Nothing could be simpler, just look for the amount of watts consumed on the labels.

There are generators for every need. Whether it’s for troubleshooting or for supplying almost all of your devices, anything is possible. Some generators actually have one capacity corresponding to 3600 W (ie 3.6 kWh) which allows power large appliances such as dryers, air conditioners, etc. Each battery allows to be paired with a second to reach an impressive energy capacity of 7200 W. The results of these devices make it possible to fight against the increase in the price of electricity.

Models up to 40W are lighter and are particularly suitable for daily travel. More powerful models need to be transported with a vehicle, such as a motorhome. This is especially the case for generators from 80 to 200W.


For the device to be practical and portable, it is important to take into account your weight. In fact, if its main use will be to accompany your escapades in nature, a generator that is too heavy will have no interest other than to make your trip painful.

In addition to weight, the dimensions is an element to be studied. Depending on the space available to you, the generator and solar panels may need to comply with certain measures. Note that some of these devices may be equipped with wheels to facilitate transportation. If not, consider placing it on a roller tray.


Pay attention to the means for charging the generator. For optimal use, the device should allow charging on an electrical outlet, a cigarette lighter, a USB port. On average with two solar panelsa generator is completely recharged between 06.00 and 13.00..

That battery quality must also be checked. Some generators have batteries that are guaranteed for two years. It should also be noted number of cycles charging to get an idea of ​​its longevity. Lithium batteries that last up to 8,000 cycles have a lifespan of at least 10 years.

The capacity

The greater the output power, the more devices it will be possible to operate. It is strongly recommended to choose a generator that offers several entrance gates.

What budget should you plan for?

The price of these devices is extremely variable. It depends first and foremost on the quality of its components but also of the amount of energy that it is able to generate. Let us give some examples.

For a generator with a power of 45 W, the price will be around 200 euros. For a device with a power of 300 W it can be off 150 to 550 euros, depending on its functionality. For units over 1,800 W, a minimum budget of 1,400 euros must be specified.

A key to the energy future

The earth receives an average of 340 W per square meter. Every year it absorbs almost 3,850 zettajoule of solar energy. To get an idea, in just one hour, this represents more energy than that consumed by humans in a year.

Solar energy is therefore one central issue in the development of our relationship to energy consumption. That in front ecological challenges, provides solar energy with a workable solution. Investing in a portable solar generator takes a step towards energy more economical and durable.

In addition, we must not forget that solar energy is inexhaustible. This means that transporting a solar cell generator means betting on achieve autonomy. It is therefore an ideal solution for all those who want to gradually slide towards one energy dependence.
