Characteristics of solar energy and solar energy method

First, the characteristics of solar energy

As a new solar energy and conventional energy sources such as fossil fuels (coal, oil, natural gas) and fuel, compared with many unmatched features.

1, solar energy directly or indirectly as energy, human play a very important role: One of the advantages is Read More…

The application of solar cells

Since the 20th century, 60’s, the solar satellite on call the shots on the power use, then gradually applied to the ground.

Solar cells in the late 20th century and the beginning of 30, 40 years into applied research. March 17, 1958 the United States launched the “Vanguard No. 1″ satellite, the first time single crystal silicon solar cells as the Read More…

Solar drying technology

It is used to dry materials, such as food crops, cash crops, leather fuel (energy) many, such as solar, coal, straw, fuelwood, methane. However, the most clean, most economical to the number of solar energy has. The general method of solar drying of crops is relatively simple, it is natural sunlight. This solar drying technology Read More…

Solar water heaters

Solar water heater is a solar energy heating the water devices. Use of solar flat-plate collector, the water can be heated to 40-60 degrees, for families, institutions, corporate life, the production offers a bath, laundry, cooking and crafts, water use can also be used for the sun room, greenhouse, cooling and thermal power and Read More…

Quality evaluation of energy

Many different types of energy, such as conventional energy sources are: plant energy, coal, oil, natural gas, oil shale, etc.; new energy include: solar energy, ocean energy, geothermal energy, wind energy, nuclear energy, hydrogen. They each have their own advantages and disadvantages. From the current technical level, the evaluation of the technical indicators of energy quality, mainly in the following areas. Read More…

Concentration of seawater

Sea water is salty

Often swim into the sea of people, will find it in the pool or rivers and lakes in the difference. First of all, your body will feel more than easy to float in the pool; Secondly, the occasional drink into a sea water, will feel bitter and salty. Why is this? The original sea water in a large number of dissolved salts. The salty sea water, the Read More…
