The solar cell is a single power generation device, equivalent to a battery with a voltage of about 0.5V and the battery component is equivalent to a battery composed of several batteries connected in series/parallel . The number of solar cell modules is generally determined by the system voltage (battery voltage). Usually, the module voltage is 1.4 to 1.5 times the battery voltage. For example: the battery voltage is 12 V and the operating voltage of the components is generally between 16.8 and 18 V, the number of battery cells is then 18 V/0.5 V, or 36 cells. Therefore, the common quantity is 36 or 40 pieces, and the high power component is 72 pieces.
There are many domestic enterprises engaged in the production of solar cells or components, such as: Suntech in Wuxi, Jiangsu Tianwei Yingli, Baoding, Hebei, etc.
TheCan solar water be used for cooking?
Yes. Battery vehicles must be fully charged before use. Newly purchased electric vehicles must be fully charged before use. Since many electric vehicles have been sitting in stores for several months or even more than half a year, they need to be fully charged before use. It is better not to use them immediately after being fully charged, but to let them stand for about ten years. minutes.
The battery must be firmly installed on the electric bike. Remove the battery to charge it. When installing, the battery should be firmly installed on the electric bicycle to prevent it from being damaged by vibration while riding. When transporting the battery, it is prohibited to throw, roll or strongly squeeze it.
Detailed information:
According to the maximum allowed charging current and voltage of the electric vehicle, the electric vehicle is quickly charged via the secondary fast charger, because the charging process is "backward charging" of the battery. energy storage towards. the electric vehicle, Rather than taking it directly from the electrical network, it does not cause any interference with the power grid (if high power is taken directly from the power grid, it will seriously interfere with the power grid, not only affecting other users, but also threatening network equipment).
Billing fees are calculated based on the actual billing amount, which is very convenient. The equipment contained in the box adopts a modular design and is equipped with special maintenance equipment for regenerative batteries. The charging station is assembled for the first time on site and can then be moved as a whole like a container as required. Isolated roads and areas without guaranteed electricity can use solar and wind power, and the principle is the same.

The water from solar water heater is not edible.
Most of the water in solar water heaters is reheated, prmainly because the water heater has been used for many years and some of it is stale water (i.e. unused water), which will accumulate dirt.There are many harmful substances in water; Moreover, even if the water in the water heater reaches 100 degrees, the heating time is very long. During this process, a lot of nitrites will be generated, which is very bad for health. health.

What type of water cannot be drunk? Let's count them together!
1: Hard water
In large cities, most drinking water has been treated. No matter how it is burned, it is almost impossible to burn off scale. However, it is different. In rural areas, after natural groundwater is boiled, the carbon dioxide and calcium and magnesium ions contained in it are released and float in the secondary water and adhere to the container. A coLong-term consumption will cause flatulence and may lead to stones.
2. Boil the water
If the water in the container is not enough to drink, add cold water and continue boiling. This boiling method is often used in life, especially. in the south, in the provinces that like to drink tea, this mode of operation is very common. The tap is located just above the kettle. Just press the button to add it then boil it again. Drink it yourself. Do not give it to children. Children are not yet fit to drink tea.
3. Water that has been boiled repeatedly
We often hear that water that has been boiled repeatedly cannot be drunk, claiming that it will be toxic. However, there is scientific evidence that this type of water is safe to drink, but the minerals in the water are reduced by repeated boiling, et prolonged consumption of this water is not good for children's health. So under what circumstances would this be harmful? In other words, if you repeat it more than 200 times, I think you won't get that bored!
4. Yin and Yang Water
So-called Yin and Yang water is cold water (raw water) mixed with boiled water and hot water. This type of water will not have much impact on adults, but it will not be suitable for children. Cold water contains a large number of impurities and bacteria, which is harmful to children with imperfect immune systems.
5. Overnight water (water that has been sitting out too long)
It's not a big problem for adults to drink (I don't think you'll leave it for ten and a half days), the duration storage. Excess water is polluted by the air and small impurities present in the air are also incorporated into the water. Some moms will want to seal it!Even if it is sealed, bacteria will grow inside the bottle. It doesn't take long to boil water, so for the sake of your child's health, try not to drink it.
