Colleagues have probably read and know the concept of an autonomous house.

Nie, dziękuję Przekieruj mnie tamQuote:Since electricity is expensive, the first step to saving it should be to adjust your lifestyle and home design to reduce energy requirements. Fluorescent lighting (fluorescent lamps), laptops and gas absorption coolers save electricity and therefore money.
Quote:During periods of low electricity demand (e.g. at night), excess energy may be stored in accumulator batteries. Unfortunately, the batteries need to be replaced every few years because of their gradual wear. In many areas, it is possible to avoid the purchase of batteries by connecting the building to the power grid, which will allow surplus energy to be sold to the grid. Such a building will be less autonomous but cheaper, requiring less sacrifice on the part of the residents. At the same time, when selling overproduction of energy to the grid, there is no loss in battery efficiency, which saves more fossil fuels.
In areas with no access to the electricity grid, the capacity of the battery bank may be reduced when a generator is installed in the system to recharge the batteries during the period of insufficient electricity supply from the wind turbine and photovoltaic cells. Such generators can run on gasoline, diesel oil, larger devices also run on natural gas. One hour of charging the batteries is usually enough for a full day of energy use.

The roofs of farm buildings in the countryside must be used, because the roofs of the houses themselves will not be enough, although, on the other hand, the village still lives more economically, maybe enough for them. In the city, for example, my building has a roof of 600 m2, and 400 people live in it, so the energy from the panels on the roof could cover several% of the demand; a further few% could be achieved by panels on the wall (unfortunately, a large part of it is covered by trees).

172: 8760 = 19.63 Watts non-stop

RADASSS wrote:No sir buddy, you still get stuck, I don't know what. When considering power, we ignore the time factor. If you can't understand it, it's hard. Ask, head a head, maybe something will flash. With energy and power, it is not so hopping despite your misconceptions.1/2 kW is just as much as the average I use non-stop in a large hut

RADASSS wrote:So, according to me 1/2 kW, if it was available from inexpensive panels, it would be ok. At the peak I charge an order of magnitude more (for max 1 hour), but that's what the batteries are for.
