Autonomous power supply from solar panels and wind turbines in Russia. Money down the drain?

A few years ago you could still find a lot of offers from companies that offer installation of systems of autonomous electrical supply: wind turbines, solar panels. These proposals meet and now:

But something I had not seen universally installed wind turbines and solar panels in new suburban areas, where there is a problem with the connection to the power grid. Most likely, these projects do not payback, especially with the efficiency of electricity generation throughout the year. And probably - even more time not working a year. And that's why:

1. Solar panels.

It requires quite intense solar radiation. In our temperate latitudes it is only available during summer. Those. at least 6 months in a year, solar panels do not work. Low flow of solar energy, a lot of cloudy days, snow, a long time on the night - it all comes down to these projects there.

But there are people who still put (or put) panel in the absence of electricity. Such a person is even in our village:

When the mains were not built, it has acquired in China solar power plant of 5 kW. Perhaps this capacity during the summer months. In principle, in the summer, when the country you are more likely - it is a way out. Afternoon panels charge the battery, evening and night - give. He says he was then this is quite enough for domestic use of all electrical power.

In Germany, the program is the use of solar energy has the state support.

If this were not a cost, it is possible to set people. The lower the cost of the equipment - the lower and the payback period.

And what prevents to make the low price? Only a large number of production and demand, supported by gos.programmoy. But when the energy monopolies have effect on gos.programmy, then nothing like this in our country will not.

2. wind turbine

Together with solar panels is a better option. When there is wind, but overcast or at night. Or windy weather in winter - will charge the battery. In remote areas, where there are no power lines - it is at least some way.

But there are days in our latitudes, the winds blow from 3-5 m / s. Wind turbine from the wind 1-2 m / s will not work. And with squally winds and hurricane - it must have a braking system, or windmill collapses.

I saw only one windmill in the vicinity of Krasnoyarsk. And it is all the time without movement.

In general, if there is a nearby power line, it is better to run with the documents for the connection, you buy for dozens or even hundreds of thousands of equipment that will not allow you to comfortably enjoy the benefits of civilization - electricity.
