Autonomous power supply for summer cottages and country houses in Russia.

Today I am talking with Alexander and Svetlana Kosarevs from Nizhny Novgorod. They have been married for 10 years, they have two children.

The main area of interest is to work on the highest quality and innovative European equipment, world leading brands.

As you can see — modern technologies, innovations, this is the main motto of this family.

Alexander, Svetlana, let’s talk in more detail about your private, innovative (for many) power system. Although it would probably be more correct to start with your purchase of an electric car. How did you come to this decision? Many are now afraid to buy an electric car, and not only because of the price (we are not talking about used Leafs from Japan), the range of its mileage on a single charge, but also because of the underdevelopment of the charging infrastructure. And probably, just after the purchase of an electric car, the question arose about an independent power supply, including for charging it. And here the Covid crisis also played a role, with the forced «self-isolation» and «pause» of many sectors of the economy, including those of its segments in which you work? And if we are to “Self-isolate”, then the energy supply should also be Self-energy supply.

Alexander Kosarev (A.K.)

The underdevelopment of the infrastructure did not scare me, because, by virtue of the nature of my activity, I was used to finding three-phase electricity everywhere: when performing technical support for public events, we connect to the power supply in any cities and fields.

About self-isolation. Yes, thanks to the period of self-isolation, it became possible to observe people’s lives in isolation from city amenities. The understanding of the most necessary devices for life in the village has come. One of the first impressions was a power outage for many hours in early spring, even during the cold season. I left for the city, and the family was left to freeze in the gradually cooling house (we have gas heating, but the boiler does not work without electricity).

The simplest is # a battery with an inverter and a charger. But this is already almost half of the # ses, it remains to add only panels and use a suitable inverter. In the period when the business was down, there was time to create its own user-friendly concept of the Solar Energy System. And immediately — implementation «in hardware» and monitoring the production of energy, depending on the weather.

We will get to the exact numbers later. I’ll start with the last question and expand on it. You have already partially answered it. But still. Why in Russia, in private households, its own RES-generation? Personally, I believe that there are two main reasons — economic and ideological. Economic, of course, in the long term, saving on energy costs, especially considering that you have to charge your #electric car. And ideological independence, which is especially necessary in cases of emergencies (emergencies), just as Alexander correctly noted, and I confirm this from my experience of resting in the village, as soon as there is a rainstorm and a thunderstorm, then almost always there is a power outage, with all the accompanying problems of water and gas supply. We must also think about how to reduce the use of fossil fuels as much as possible. And not because it is kind of abstractly good and correct, but because it is actually necessary, which, again, was proved by the Covid crisis. Scientists in many countries have established a correlation between air pollution and the incidence of disease. Yes, you can even understand this easier by wiping the windows of a city apartment or glass in cars with a napkin. We will see black soot on it. And all of this we breathe, because of this, the incidence of the human respiratory system is increasing, asthma and other diseases appear. But we want our children to grow up in a clean environment and not get sick.

By the way, there are those who will say that we have little sunlight and this, like, will not be effective. And this statement was easily refuted by Evgeny Kazanov, having passed with his team on a solar catamaran along the rivers of Russia, from St. Petersburg to Astrakhan.

I will answer, perhaps, the most pressing question — about the cost of the project. I have not yet calculated it «to the ruble.» This is due to the fact that I had some of the equipment in the warehouse and is used in my main activity, namely the metal base of the structure. Then I spent about five hundred thousand rubles for the station in its original form (what you saw on Svetlana’s Facebook page).

Now I continue to experiment and increase the number of panels.

How much energy does it generate?

«

3 floors, respectively, but not yet measured.

But you need to understand that it was in the summer. According to calculations in winter, solar energy in our strip is about 10 times less.

Alexander: when SPP is for private cottages / houses, the question of recoupment does not arise. Again, this is about the buzz of life, for security, for backups.

If a person has this money, he spends.

And if it gets up, then you don’t need to use expensive batteries.

When there is commercial use to save money, then you need to use a network SES without batteries. In this case, the payback period is from 4 to 7 years.

Solar cell area

Is there enough solar energy for home and car charging?

It depends on which car and the number of panels.

There is enough for the house completely.

On

Our house consumes per day

Those. if you treat it wisely, you can fully provide a house and charge a BMW in 1 day in the summer.
