Sunny panels for charging a car battery
To highlight popular models from leading manufacturers indicates the accumulation of experience using such devices among ordinary consumers. If one of the motorists has questions, then acquaintance with this publication will remove their main part.
The production of electric energy from sunlight became possible, thanks to the studies of many scientists. The starting point was the opening of a photogal effect in 1839. After a hundred years, semiconductor photoelectric elements were invented, which converted the radiation of the sun into direct current.

On a note. The first solar batteries of the modern type on silicon crystals were developed in 1954 by Bell specialists, and after four years the USSR and the United States launched satellites equipped with such devices into space. By the beginning of the 21st century, many types of photocells appeared, and their use in everyday life has become an ordinary phenomenon.
Experiments of car owners in direct recharging the battery with household solar panels pushed manufacturers to the idea of producing specialized devices that can solve several problems at once, such as:
- Charging of car batteries without load on the network;
- Getting rid of the need to carry back.Up batteries with you;
- Risk reduction to emptied the battery with a non.Working generator;
- Recharging batteries with a simple engine;
- Increasing the efficiency of recharging on the go.
It is obvious that for owners of various electric cars and hybrids. The listed problems are especially relevant, even if transport or equipment is equipped with a gasoline generator.

Solar battery for a car battery
You can solve the battery charge in several ways.
First option. This is a solar battery to maintain the battery charge.
This solution is suitable if your vehicle will stand without movement for a long time. And you will not use the current on the on.Board network. Sunny batteries of low-power 7-18 watts are installed both outside and inside the car (under the windshield) and connected directly to the cleones or using the standard cigarette lighter connector. Regardless of the location, the solar charge will fuel the battery, and even after a long time you can start without problems. The following models are suitable for such purposes. Allpowers 7.5 WATT 12 V, Allpowers 18 WATT 12 V, Allpowers 21 WATT DC 9-18 V. These devices are created specifically to maintain and recharging 12 volts batteries. I come in the kit for terminals for terminals and for a 12 volts socket in the cabin. All of the listed panels are very light and compact, due to the fact that the most modern solar elements are used. Model 21 watts by the way, in addition to charging, the battery can easily directly feed a smartphone or tablet.
The second option. Solar battery for charging the battery.
This method is suitable if you need to quickly charge the battery of a large container, and also if you plan to use the current of the on.Board network for charging a phone, a laptop for example or a car refrigerator while parking. In this case, we recommend that solar charging with a capacity of 40 to 100 watts are recommended for use. Such devices will be able to charge the battery of 60 Ah in 7-18 hours (depending on the power of the solar panel). In addition to charging the battery, these devices will also be able to charge the phone, tablet, laptop and nourish the car refrigerator. In our assortment, the following batteries will suit you. Allpowers X-Dragon 40 Watt, Allpowers 60 Watt, Allpowers 80 Watt, Allpowers 100 Watt. With them in the set, everything you need is supplied for charging.
When choosing a battery, we give you a formula for calculating charging speeds. For example, you have a battery of 70 ampere hours, and you chose a battery with a capacity of 60 watts. It is necessary to divide the power into voltage, in this case, 60 watts by 12 volts and we get 5 amperes per hour. This is a charging current. Now you need to divide the battery capacity into current 70/5 and get the value. 14 hours, this is how much it will need to complete the charge of your battery from 0 to 100 percent. This formula is universal and is suitable for calculations with any batteries and batteries.
Very often, our buyers ask a question about reliability and whether the solar battery will disable the battery. All our solar panels are equipped with a current and voltage controller, and a special protection system will automatically turn off the current supply if the battery is 100% loaded (reloading protection).
We hope that this material will be useful and will help to deal with the choice of a solar battery for your battery. If you still have questions, write them in the Комментарии и мнения владельцев, on our email, as well as call the contact numbers, we will be happy to help!

The S-Freedom Mark already mentioned in the article is always released with all the necessary accessories. The line is represented by models with power 40, 65, 80 and even 120 watts. The higher the power indicator, the greater the charge speed will be.
Sunsei solar power sources are also a good option. For example, the SE-500 portable panel is configured with a moisture resistant cover and a tripod on which it is reliably installed. Such a battery can have a car battery for several hours with a drowned motor. The kit includes terminals and a fork for a auto.Smoking. Her power is small, but there is always the opportunity to place several batteries on the roof.
The Canadian SunForce panel is characterized by equipment of higher power. At 150 WATT current strength is 8.7 A. The configuration includes a controller, fork and terminals. The panel is perfectly placed on the roof of the car or even a small yacht. This model differs in that it can work in conditions of foggy and rainy weather.
TSM 15-F panel is a portable and convenient variety with a flexible, but durable case. Power level. 15 watts at a current of 1 ampere. Convenient in transportation and placement, fixation is reliable and strong.
Thus, the solar battery for charging the battery is no doubt a useful and desired device that can always help a motorist in difficult road conditions. If you have such a device on the roof of a car, it will always be useful on the way. Of course, you will have to be prepared to constantly monitor how the design is fixed on the roof. Especially if there are several panels. In order for the solar battery to serve much longer, it is worth purchasing the goods only from trusted manufacturers and pay special attention to the strength of the material from which the case is made.

A review of a small solar battery, or an attempt to understand whether it is possible to charge batteries from a small solar battery
Hello! I decided to gradually start writing reviews for many necessary and not very goods purchased in China. The first in line is a small solar battery, decided on my own experience to find out its capabilities in charging the batteries of Powerbank or phone directly, say in nature. I will try to do without very fashionable words like DIY, device and the like, I am for Russian! I bought the panel last year and I decided to write a review only now. It reached quite quickly, packed standardly in a yellow bag and wrapped in polyethylene foam, the working surface was additionally sealed with thin polyethylene for protection against scratches. The panel itself is made on the basis of fiberglass, approximately the one from which printed circuit boards are made, so it would not be easy to break it, I was initially afraid of whether it would come intact, because I believed that the panel is whole.Masculinated. The dimensions of the panel are 9797 mm, 1 mm less than the seller is indicated, but this is not critical. Power 1 W is promised, at a voltage of 5.5 V, and current 0.18 A, but these are the maximum parameters obtained somewhere in the desert, when the sun is in the zenith, this will never work out in our lane. All winter, the solar panel was glued to the window and connected to the Powerbank for 3.6 ah, in winter the sun on the other side of my house and batteries charged in a couple of months from 3.30 V up to 3.38 V, extremely insignificant, but now the sun is almost directly hit, and the same batteries managed to charge from 3.30 to 4.20 volts in about two weeks, despite the fact that constant cloudy was at that time. In the summer it will be better. Measurements on the contacts of the solar panel were shown under load 4.12 Volta, which is not bad, given that it is very cloudy, the current is now a few milliamps, I can’t measure more precisely because of a significant voltage drop in my avometer. I tried to photograph something like it really looked. I don’t have a luxury and the ability to measure illumination.
You can charge a total of a phone or Powerbank from such a small panel, but for a very long time, but most likely for a small recharge of some simple phone or player with a battery with a capacity of 700-800 mAh on a clear sunny day, it will have enough to work out to these devices longer. The solar panel was bought only for such an experiment, and now it is hanging there on the window, rechargeing Powerbank, I have not found other applications for it yet, but lovers can use something with their own hands for, for example, for a small robot, or something else.
And of course a cat, for a good mood!)
Charging rules
Controller of the charge. If it is not, it is necessary to purchase and attach to the charger. This will avoid reloading or reverse discharge of the battery, which negatively affect the condition of the battery plates. If possible, it is recommended to use a chain of several solar panels, distributing them with the most convenient way for taking sunlight.
Various models of solar panels. Most of them have been produced in the countries of Southeast Asia and have appropriate technical capabilities. The acquisition of such devices is always akin to participating in the lottery. It is never known how it will end this time. Nevertheless, there are quite efficient and high.Quality solar panels for charging a 12V battery.
A small review of which will help to orient the potential user:
- SUNSEI SE-500. Brainchild of ICP Solar. It is a compact and productive solar panel, the dimensions of which are 38x36x3 cm. The power of the panel is 7.5 W, and the current strength is 0.6 A. Relatively small power is compensated by the ability to connect several devices into a single system, which allows you to increase the output power and accelerate the battery charging. The model is equipped with a bar (tripod) for installing the panel in the most convenient position.
- Sunforce. Famous Canadian company producing solar panels for various purposes. The 17-watt model has a current strength of 1.5 A, the dimensions are 97x35x4 cm. Recommended placement. The roof of the cabin or car cab. The kit has a charge controller, terminals, fork for a cigarette lighter. The difference between this model is a high sensitivity of photocells, which allows to obtain solar energy even on cloudy days.
- TSM-15F. Compact flexible panel size 60x27x0.5 cm has a power of 15 W, current strength 1 A. Despite the flexible shape of the case, it is reliably sealed and taller. The battery is placed on the roof of the cabin, provides an efficiency of 22 % and fully fulfills its task.
New models constantly appear on the market, allowing you to get more energy. Manufacturers are engaged in the development of more effective devices that can speed up loading and receive energy in an unfavorable weather situation. When buying, you should carefully study the technical characteristics and do not be shy to demand certificates of conformity that always have high.Quality solar batteries.
Conclusions and useful videos
The charger on solar panels, reviews of which have a very versatile orientation, is a necessary and useful device that allows you to maintain communication or the ability to use mobile devices in the field. A phone on a sunny battery is an attractive idea that gives real autonomy and mobility without linking to network power sources.
Unfortunately, various unknown firms from Southeast Asia are most actively engaged in the manufacture of such useful things, the quality of the products are frankly low. Users who had the opportunity to evaluate the work of charging on sunny batteries for the phone, give reviews not always positive. To familiarize yourself with the work of some of these devices, you can watch a video:
