12 volt solar panel specifications

The fact that a few decades ago seemed to be the technology of the invisible future, today embodied in reality and is available for use. Obtaining electricity from solar energy for many years mastered and successfully used. Now everyone can provide themselves with special elements that extract free autonomous electricity.

The solar cell is able to generate natural energy, the source of which is the light of the sun's rays. This is due to a special plate, which is the basis of these devices and structures. The surface of the sensitive plate captures daylight, accumulating it already in the form of electrical energy.

The advantages of a natural autonomous source of electricity are as follows:

• When using the source in the home, you can significantly reduce the cost of electricity. The magnitude of the savings will depend on the consumption of electricity in the house or apartment and on the capacity of the solar battery;
• the design can be used anywhere. Portable panels can be taken on a hike or on vacation. With their help in such conditions it is possible to charge cell phones, laptops, flashlights and other low-power electrical appliances;
• Depending on the purpose of use and the required amount of electricity, it is possible to assemble a system of the required power and configuration. With the help of solar panels, you can even provide a separate house with uninterrupted electricity. There are more than one example of such an application of these devices in the world;
• This method of producing electricity is safe and environmentally friendly. It does not adversely affect the environment, does not require the construction of bulky structures or the use of chemical and atomic substances.

Solar panels have such disadvantages as:

• they are able to generate electricity and feed only when in contact with sunlight. In cloudy weather, devices also capture solar energy, but in smaller quantities. You can correct this problem with the help of batteries and controllers;
• to generate a large amount of electricity, panels of rather large area are required. In this case, they are placed on the roof or side lit walls of the building.

For autonomous feeding of electrical appliances on a camping trip or on vacation, a 12 volt solar panel is a good option. This module can also be used for short recharging of a dead car battery. The panel is able to charge the phone with a battery capacity of 300-400 mAh. If you need to collect and generate more electricity, it is worthwhile to assemble a system of several panels.

12V solar panels have the following characteristics:

• maximum power is at least 48 W;
• maximum voltage - 17.1 V;
• maximum current - 2.82 A;
• short circuit power - 3.0 A;
• for a light day in conditions of the middle band and latitude of Moscow, the solar panel is able to accumulate up to 200 watts. With a stable cloudy weather - up to 100 watts;
• temperature limit for use is from -50 to + 70 ° C;
• the module is able to work correctly at a humidity of up to 100%;
• the service life of the device declared by the manufacturer is at least 12 years;
• complete set of solar module: solar panel (1 pc.), cord for round connector (1 pc.), cord for round connector with crocodile clip (1 pc.), panel case, passport and instruction.

Solar panel 12 has such advantages as:

• increased durability of the panel due to the small dimensions of the device;
• generating plates are coated with anti-glare;
• Silicone insulation of the wires makes use at low temperatures more convenient, since the insulating coating does not harden in the cold;
• on the wires is protective shrinking;
• the module is equipped with eyelets for mounting.

For an autonomous mini-power station, the following devices will be required:

• controller to monitor the degree of charge of the solar battery. This device helps to significantly extend battery life, as it controls the charge level;
• an inverter device for converting the flow of electricity into alternating current;
• intensively generated in sunny weather, electricity is not always consumed immediately and in full. In order not to lose the excess in vain, it is advisable to connect a stationary battery to the system. The electricity accumulated in it can be spent later at night or during long cloudy weather.
