What is solar power and the role of solar energy? (Part 2)

Other applications from solar energy

Create water heaters using heat from the sun for use in living, swimming pools, …

Solar heating system is applied in construction, using monolithic materials such as stone, cement, water, …

Water treatment systems use solar heat and solar electricity to desalinate or disinfect

Solar cookers, people also use the technique of converging sunlight to create heat for cooking, typically industrial kitchens in India are serving up to 35,000 meals per day.

Solar electric vehicle

Countries around the world have developed various types of solar-powered vehicles such as cars, planes, ships, balloons. In Australia, they hold an annual race called the “World Sun Challenge” for universities and businesses to compete on long distances of 3,021km, the most recent winners’ speed up. to 90.87 km/h.

Solar power storage

Since solar power generating systems only generate electricity directly in daylight conditions with good lighting, storing electricity or maintaining solar power generation for service at night is a problem. important issues to deal with.

To regulate the temperature in the home, construction engineers design monolithic systems to store the sun’s thermal energy to warm or cool the home.

For the operation of CSP plants (centralized solar power plants), use molten salt stored in storage tanks to keep the plant running.

With photovoltaic battery systems to generate solar power, the most common form is using rechargeable battery systems for complete storage (for independent solar power systems ) or excess electricity. (for grid-connected solar power systems ).

The development of solar power

With the development history of photovoltaic batteries over half a century, the technology and efficiency of solar power systems have increased significantly, major manufacturers in the world are still constantly researching to improve the performance of solar batteries. Manufacturing standards and raw materials are also being raised to meet health and environmental requirements.

Great benefits from solar power

Solar power is the source of electricity converted from sunlight energy into electricity, so first we have an infinite resource to exploit.

Economic significance of solar power

The supply is endless, the cost of producing solar cells is decreasing, the output of electricity is increasing over time, contributing to reducing the cost of electricity consumption.

Energy security

Future solar power could replace other forms of electricity generation from burning fossil fuels as well as restrict hydropower changing ecosystems.

Environmental benefits of solar power

Solar power is recognized as a green, clean and environmentally friendly source of energy, solar cell recycling technology has also gradually improved, according to 2014 statistics,  the average CO2 emissions of solar power is 41g/kWh compared with coal power is 820g/kWh and oil and gas is 490g/kWh

In addition, solar power is widely used in human life from daily life to production, capable of deploying on a very diverse scale and suitable for all subjects.
