The ability to receive free electricity by the wind appeals to many owners of individual houses, but a certain part of them fails, is disappointed in this method and writes negative reviews in various forums. But you can avoid mistakes in creating such installations and get the most out of them.

The wind generator with its electrical circuit and design principles resembles any other generator. The main difference lies in the method of spinning its rotor due to the kinetic energy of the air flows captured by the aerodynamic blades.

The speed and power of the wind must reliably rotate the impeller of the engine, the energy of which is consumed by the generator. If this is not done, then you will be left without electricity. An estimate of the likelihood of an active wind will help ...

When choosing a solar power plant and analyzing the options for operating solar modules, it is important to determine the potential for solar energy.

The science of "Insolation" (formed from the term "in solis") is involved in accounting for the irradiation of the Earth's surfaces by the rays of the Sun. It takes into account the direction of a parallel beam of light rays from the center of the solar disk by geometrical and energy methods, which make it possible to identify for the light flux: direction, cross-sectional area, dependence on time and season, density, exposure in light units.

The location of the solar battery affects the quality of reception of the light flux, is determined by the angle of inclination of its surface relative to the axis of the light rays. In practice, it can be oriented in different ways, but three characteristic options are chosen for calculations ...

In the energy sector, it is often necessary to convert some quantities to others because electric energy is produced by sources of alternating or direct current. Corresponding consumers are created for them: electric motors, transformer devices, household appliances.

In many industries, as in alternative energy, there is a need to exploit consumers from combined sources. Rechargeable batteries are charged, and electronic devices, computer devices are supplied with direct current or rectified from electric power generators with a rotating electromagnetic field.

The inverse task of the electric motors of the sinusoidal harmonics of household electrical receivers from direct current sources is solved by converting electricity into variable using ...

In modern solar power plants, different schemes for connecting current sources are used to transfer the generated electricity to working batteries. They use not the same algorithms, are based on microprocessor technologies, called controllers.

Electricity generated by the solar battery can be transmitted to storage batteries: directly, without the use of switching devices and control devices, through the controller.

In the first method, the electric current from the source will go to the batteries and will increase the voltage at their terminals. Initially, it will reach a certain limit value, depending on the design (type) of the battery and the ambient temperature ...

In the solar energy sector, batteries occupy a special place, which play the role of an intermediary in the transfer of electrical power to end-users. This can be explained by the fact that the maximum amount of electric energy is generated by the solar battery during intense light exposure that occurs in the daytime.

However, its greatest consumption is carried out with the onset of darkness, when lighting with household appliances is massively used. Batteries allow you to save surplus electricity generated during the day for evening and night use.

Of course, as an option, in the daytime you can turn off part of the working solar modules in the reserve, but this will not solve the issue of evening electricity shortages. Any electric batteries are considered as reusable direct current sources ...

Various alternative sources of electricity are increasingly interested in homeowners. They are attracted by the low cost of using solar energy. But the mass introduction of devices operating from the solar light flux is constrained by the high cost of equipment and the complexity of its selection and installation. In fact, to assemble with your own hands and operate a solar power station is within the power of a home master, even a senior student. To do this, you need to: familiarize yourself with the principles of operation of the circuit, determine the tasks of the equipment, select the most suitable equipment for the station, conduct mechanical installation of all elements, assemble the electrical circuit, verify operability and correctly operate it.

Numerous practical experiments allow us to recommend a universal scheme for solving the problems of a solar power plant for the home. It includes: solar module ...

This article is intended for those who want to connect the gas generator to the ABP unit without assistance. But, before you start connecting the generator to the automation, you need to know a little about the device and the principle of operation of the generator.

There is no sense in thoroughly understanding the device and the principle of operation of mini-power plants, this information on the Internet is more than enough, we just need to understand how the generator works, where you need to connect the control wires from the autostart system. That is, only practical information, without unnecessary theory and "water."

This method of connecting the generator is suitable for most single-cylinder generators up to 5-6 kW equipped with an electric starter. So, for starters, consider how a gas generator starts up. Close the air damper before starting the engine., turn the ignition key to the "START" position. After the generator engine wound up ...

Power supply systems using autonomous sources are becoming increasingly popular among owners of country houses. It is understandable: the cost of electricity supplied centrally is growing steadily year by year. In addition, the quality of this electricity often leaves much to be desired, and constant power outages in some regions generally preclude the normal use of the benefits of civilization. Then the idea will inevitably arise of having your own power source and not depend on anyone.

There are several ways to provide autonomous power generation at home, but, unfortunately, all of them are not without their drawbacks. Consider the main ones in more detail. Gasoline or diesel generator set. The advantage of these installations is true autonomy ...
