Fossil fuels are gradually exhausted due to the continuous development of human beings, and green power generation has become the energy development strategy of all countries in the world, among which the inexhaustible solar energy has become the focus of development of renewable energy. The government has listed best solar panels canada as a key development project for energy conservation and carbon reduction, and the private sector has also risen a green energy financial boom. Before joining this green energy trend, it is necessary to understand the operation mode of converting sunlight into electricity. This article will introduce the power generation principle, electricity calculation and life application of solar energy.

Principle of solar power generation

The main equipment of solar power generation includes solar panels, special batteries, special inverters and so on. Solar panels are the first step in power generation. After receiving sunlight, the photoelectric semiconductors in the panels convert the radiant energy into direct current. Then, the direct current is converted by the photovoltaic inverter into alternating current that meets the mains frequency, and the generated power is stored in the battery, or connected to the grid for scheduling use.

How to calculate solar energy generation?

The amount of solar energy produced varies with geographic location and the amount of sunlight. Based on the data released by Taiwan Power, if the system device capacity per kilowatt (kW) in 107 years is located in Keelung City, the annual average can produce 322 KWH of electricity, and in Taipei City, it can produce 1002 KWH of electricity. There is a difference in the amount of electricity that can be produced in different counties and cities, and each kilowatt system device requires an area of about 3 ping

Taking electricity in life as an example, if you want to supply 110V electrical appliances for 24 hours, the maximum output current of 100W solar panels is about 5-6A, you need 6 solar panels, which can supply computers, mobile phones and general small household appliances.

Factors affecting solar power generation

1. Amount of sunshine: Solar power generation is proportional to sunshine intensity and sunshine time, so the power generation is better in the sunny summer and the low latitude area with long sunshine time.

2. Solar panel power: In the process of solar power generation, the operating power of the panel will directly affect the power generation effect. Among them, the quality of the semiconductor, the efficiency of the photovoltaic inverter, and the resistance of the transmission system will affect the amount of electricity produced by the panel, as well as the energy lost during transmission. With the advancement of the manufacturing technology of solar panels, the quality level of panels has been steadily improved, and the cost is low compared to the early stage of development, so that solar energy can be applied to a variety of products, and green energy power generation can be implemented in life.

Solar power application

1. Solar household appliances

For power products with small power consumption, solar energy can meet the needs of no plugging, no location restrictions, and no need to replace batteries. Including solar watches, solar electronic computers, solar water heaters. In addition, in remote areas where it is not convenient to erect power grids, solar street lights can also be set up to meet the needs of infrastructure construction. Power is supplied in the most environmentally friendly way, and the cost of installing grids and pipelines is eliminated.

2. Solar buildings

Building electricity consumption is relatively large, compared with the pull circuit, the installation of solar panels on the external wall to produce electricity and self-sufficiency, it is not a small complement. New buildings can use solar panels on the exterior walls instead of traditional materials, while existing buildings can have solar panels on the roof. Solar buildings have become one of the fastest growing solar applications.

3. Solar roof and building

In addition to using solar products, you can also set up a solar roof on your house. The government has also promoted sunshine community subsidies to encourage people to participate in solar energy, and if people want to sell electricity to Taiwan Power, they are guaranteed to buy it at a fixed preferential rate for 20 years. In addition to erecting their own solar panels, Zhonglet-All Power Plant has launched a service to assist in renting roofs and erecting solar panels, so that people can easily contribute to the sustainability of the planet.

Green can be re-evolved, and solar energy has unique advantages

Compared with other renewable energy sources, such as wind and hydropower, the setting conditions of solar panels are less limited, wind and hydropower must be in the strong wind or water level difference, solar power only in the sunshine can be set up. Solar power generation costs are small, their own roof can be erected, there is no need to set up such as wind turbines and other huge equipment. In addition, if the roof of their own solar power generation, there is no need to remote power transmission, but also greatly reduce the loss of energy in the transmission process. The advantage of solar power generation is that traditional power generation can not be compared with other renewable energy sources, and therefore has become a key project in the development of renewable energy around the world.
