If you are planning to provide your home with electricity obtained from solar panels, then you need to understand that in addition to the batteries themselves, you will need some additional devices and components. The main nodes in this system will be sources of electricity and storage (just like in the case of wind turbines). The remaining devices can be classified as auxiliary, but also very important.

So solar panels are the source of electricity. Their number and total capacity depend on the volume of electricity consumption, time of year and region of residence. When calculating the required power of sources, it should be taken into account that most energy-intensive appliances consume electricity for a short time, so the average power consumption in an average family can be from 200 to 600 Wh or 4,8-14,4 kWh per day. It is necessary to calculate how many solar panels can produce the power you need per day. If, at the same time, you try to reduce costs by using more economical appliances or by eliminating some of them (for example, replacing an electric kettle with a conventional one heated by gas or stoves), then the cost of purchasing power supplies can be reduced.

Batteries are energy storage devices. There are many different types of them, which we will not talk about now. The main advice when buying drives can be a recommendation to buy several batteries of a smaller capacity instead of one large one. It is necessary to buy drives at the same time from the same batch, then they can be connected together if necessary and get a large capacity without harm to the batteries. The most rational would be to connect your own system to each room of the house, when each room is responsible for its own source (or a group of them) and its own drive.

Between the source and the drive there must be wires through which, in fact, electricity is supplied, as well as a charge-discharge controller for the battery. The controller allows you to prevent overcharging the drive and protect it from excessive, harmful discharge. For some reason, it is generally accepted that the controller is only an additional, completely unnecessary and costly device, which also draws electricity. But actually it is not. It is better to buy a controller once than to constantly spend money on disabled drives. Partially, the function of the controller can be performed by an electricity converter from 12 to 220 volts, but it is used only in 220 volt networks and is not able to control the recharge of the drive.

Wires that go from the source to the controller, from the controller to the battery and from the battery to the converter, it is desirable to acquire the maximum cross section. The larger the cross section, the less will be the loss of electricity during transmission. Any wires can lead from the converter to the sockets. However, if you are going to arrange a 12 volt network in the house, then there are special warnings for wires. First of all, try to also purchase a wire with a large cross section. The longer the wire from the battery to the devices, the greater the loss of electricity. Try to make the system so that the wires have a minimum number of connections, as there will also be current losses on the connections. In this situation, it would also be most rational to equip each room in the house with a separate network with its own source and drive. This will help keep the length of the wires to a minimum.

Separately, I want to say about the converters. These devices allow you to get standard 220 volts in the network. At the same time, they require a certain amount of electricity for their own work. In addition, there may also be power losses in the conversion process itself. That is why it is recommended to use converters only for those devices that cannot be converted to 12 volts. These appliances include laptops, irons and other heating elements, as well as some motorized appliances. Pumps, vacuum cleaners, refrigerators, mobile phone chargers and even washing machines can be made for 12 volts. Well, lighting today is generally developing at a gigantic pace and may well do without the need to connect a converter.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Random news from the Archive Humidifier Purifier 05.09.2001 The only one of its kind and unparalleled small-sized and simple device for cleaning, humidifying and sterilizing the air of residential and small industrial rooms. Polluted dry air is sucked into the device and enters the lamellar drums with a high specific surface area (up to 4,2 sq. m), rotating in water. Mechanical dust particles (up to one micron in size) linger and settle in the aquatic environment. At the same time, clean water is intensively evaporated from the large surface of the drums. The ambient air is optimally humidified. In small quantities (up to 50 ml), a bioabsorber is added to the water, which neutralizes pathogenic bacteria and other impurities of the air being cleaned. It is said that the famous Spanish tenor X. Carreras uses this particular air purifier in the rooms where he prepares for performances in opera performances and concerts. Once every two weeks, the drums are washed in the shower, and the tray is filled with fresh water and a new portion of the bioabsorber. Drum replacement is not required. The device is almost silent. Depending on the model, it serves rooms of 30 - 80 square meters. m. Overall dimensions (in cm) - 27x30x26. Weight 7 kg. Power supply - from the mains, power consumption is not more than 38 watts.
