Common sense of the Spring Festival refrigerator: less storage staple food in the refrigerator

During the Chinese New Year, there may be a staple food that cannot be eaten at home. Some rice and noodles containing more starchy ingredients are placed in the refrigerator for refrigeration. The cooked and gelatinized starch can form a hard crystal due to low temperature. This is usually Said "age" or "return". Once the starch is aged, it will not heat up.

Solar Panel

solar panel

A solar cell panel, solar electric panel, photo-voltaic (PV) module, PV panel or solar panel is an assembly of photovoltaic solar cells mounted in a (usually rectangular) frame, and a neatly organised collection of PV panels is called a photovoltaic system or solar array. Solar panels capture sunlight as a source of radiant energy, which is converted into electric energy in the form of direct current (DC) electricity. Arrays of a photovoltaic system can be used to generate solar electricity that supplies electrical equipment directly, or feeds power back into an alternate current (AC) grid via an inverter system.
