Solar power stations.
The solar power station for private households is not an element of fantastic stories today. This is a real, affordable and effective system that allows you to convert the energy of the sun into electricity. It allows you to fully meet household needs, and it is profitable to sell surplus goods to a common electric grid. Moreover, the state strongly supports the transition to the use of solar power plants.
Home solar power plants make it possible not only to unload networks, but also to earn good money by connecting a "green tariff" and selling energy to the state.
What is a green tariff?
The "green tariff" is a special financial condition that allows private households that produce electric current using a solar station to sell it to the grid. And at a price that is 5-6 times more than the cost of a kilowatt for ordinary consumers. The benefit here is obvious.
This program is protected at the state level. Anyone can produce and sell electricity without a license. "Green" tariffs and the cost of a kilowatt (kWh) are protected by law until 2030.
There is a certain gradation of the cost of one kW. Beginning in 2013, it changes to a decrease. If initially the price was 0.36 euro per kWh, now it is 0.19 euro kWh, and in 2030 it will be 0.14 euro kWh. This decline is due to the fact that the market is actively developing.
Such conditions motivate the population to install private solar power plants more quickly. The sooner you install it, the more you can sell energy. This price is fixed. Those who were the first sell at 36 euro cents, and today it is almost 10 hryvnia per kWh, while they buy energy at 0.71 UAH / kWh.
However, there is one restriction: it is not possible to connect a domestic power station with a capacity exceeding 30 kW to the "green" tariff.
If to summarize, the "green tariff" for a private household is the difference between electricity produced and consumed. This is the net profit of the owner of the solar power plant.
How much does it cost to install a home solar power plant? Take for example a house of 100 square meters. m.
The cost of installation does not depend only on the area of ​​the house. That is, this is not the most important factor. Here is a slightly different calculation principle.
If everything is explained step-by-step, the expert will first go to the site and inspect the house: will the technical conditions of the electricity grids allow installing photovoltaic panels and how much power is allocated per house in kilowatts. The maximum power is up to 30 kW. This is the limit that can be "bought" in Oblenergo for the construction of a power plant. That is, in order to install an electric station for 30 kW, a cable of 30 kW must be brought into the house. And in accordance with him, the counter and all the technical conditions.
The next step is to install the equipment and perform a trial run of the system.
Then document this to confirm and conclude a contract for the supply and sale of electricity from Oblenergo.
Then open an account, which will receive funds.
And the last step is to connect this tariff and make a profit.
A solar power station for the house always pays off. The specific period depends on the installation region and the volume of own consumption. Usually it takes 4-8 years to use the payback.

Swivel solar tracking device

At the dawn of the existence of solar energy, solar panels were installed permanently and stayed in one fixed position. The overall dispersion of the sun's light, which was used, did not give the desired result. More precisely, the result that humanity received, it was impossible to call it ideal for all its indicators. The system of tracking the sun removed this problem.
The maximum energy that can be obtained will be generated in the case of the perpendicular direction of the sun's rays on the plane of the batteries. In the opposite case, the efficiency of solar cells is extremely small - about 10-15%. If you use the automatic battery guidance system in the sun, you can increase the result by 40%.

How it works

The tracking device consists of two important parts: a mechanism that rotates and tilts the batteries in the desired direction and an electronic circuit that drives the mechanism.
The location of the batteries is determined by the geographical breadth of the terrain where they are to be installed. For example, you need to install batteries in the area, which corresponds to 330 north latitude. This means that the axis of the device should be rotated by 330 in relation to the horizon of the earth.
The rotation itself is possible thanks to the motor, whose operation is regulated by the automatic system. Automation "watches" the location of the sun in a skyscraper and as it moves westwards it signals the engine to rotate all the batteries.
Interesting and curious is the fact that the power for the engine comes from the solar cells themselves. Watching the sun makes the sun itself, and this is also a cost saving.
Design Features
For detailed perception, let us give an example of how solar beams were used by batteries earlier. For example, a solar battery is made of two panels, each of which contains three elements. Elements are connected in parallel. The panels are mounted in such a way that there is a right angle between them. In this case, at least one panel will in any case "absorb" the sun's rays.
Panels form an angle of 900, the bisector of which is directed strictly to the sun. If the whole structure is rotated 450 to the right or to the left, one panel will work, the second - idle. This position was used to catch the sun's rays with one battery in the first half of the day, and in the second half the second battery is taken for the job.
However, with the use of a rotary auto-tracking device, you can forget about the problems with the location of the batteries forever. Now all of them without exception will have turned at an angle of 900 surface to the sun.
The automatic rotation scheme should also take into account the presence of factors that limit the energy of the sun's rays for greater efficiency. It makes no sense to use food in case of fog, rain or clouds, when the sun is hidden completely or partially.
Sale of solar trackers
The offer of our company is to provide a complete system for tracking the sun, developed by specialists of the company "Rose of the Winds" and produced in accordance with the highest quality standards with the use of the most modern technologies and high-quality materials.
The solar tracker TM "Wind Rose" is an atomic rotary design for solar cells, dynamically oriented relative to the position of the sun, providing an optimal position of the solar modules. Accurate tracking of the sun is achieved through systems with one or two tracking axes.
The construction of the tracker TM "Wind Rose" consists of stainless steel and aluminum profiles, where solar panels are installed. The use of trackers allows you to most effectively orient the working surface of your panels and greatly increase their output capacity in comparison with placing on fixed metal structures.
The management of solar trackers TM "Rose of the Winds" is carried out through a program running in a Windows-CE environment on a tablet computer.
Advantages of using our solar tracking devices:
· The efficiency is increased by 20-60%, depending on where in the world the solar power plant is installed.
· The space required for a solar park is reduced, while maintaining the same result.
· The payback period of investments is decreasing.
· Automatic operation mode.
· The system does not require constant supervision and care for it.
Our company offers two types of solar trackers: one-axis and two-axis
One-co-ordinated solar tracker (orientation of the tracker occurs in one plane "left-right" in the range from -75 ° to 75 °). To maintain accuracy, single-axis sun tracking devices are manually adjusted to compensate for seasonal ecliptic shifts that occur with the onset of each season.
Two-coordinate solar tracker (orientation of the tracker occurs in two planes: up-down: -10 ° to 75 °;
