The Advantage Of Solar PV Power Generation

Solar pv power generation means through absorbing the solar radiation to generate electricity, if only there is sunlight ,it can install the solar power system. The generate electricity process and principle of solar pv power generation are very simple, it doesn’t like the fuel generator to mechanical motion, or consume the fuel, even generate any hazardous substance or gas. Recently years, which is the new energy source using project strongly promoted all over the world. 

Why solar pv power generation become more and more popular in the world ? Specifically speaking, there are three main advantages as below :

First, energy source are free, and have a sustainability. Solar pv power generation via absorbing the sun radiation to generate electricity, the solar energy is the most precious free source which the universe present to our human being. According to the statistics, exposure to the earth solar energy is much bigger than our wasting energy about 6000 times, this source all around the earth, do not subjected to geographical and altitude factors limit.

Second, convenient to use. If there is sun light , it can install the solar power system to power supply. Flexible distributed, solar power system can be eight big or small, large to the solar power plant, small to our Poweroak portable solar generator, both can nearby power supply. That is to say, it is suitable for tourism, exploration, household lighting, pasturing area, field working, forestry home, island fishing boat, border posts and other areas without or lack of electricity power.

Third, no pollution, no pressure on the environment. All process of solar generating are physical, don’t burn the fuel, and will not generate any substance, no pollute the air, don’t make the noise, either. It is really a green environmental renewable energy source.

Besides, with the improvement technology of solar power system utilization, generating efficiency will be great progress, and these advantages will be more and more appeared. What’s more, The home solar power system will take a good market opportunity and have a great development.

The Solar Photovoltaic Power System Disadvantage

Recently years, solar energy have been great promoted and developed. In western country many households and organization have installed solar power system to power supply. Solar photovoltaic power system advantage have become more and more acceptance. In China, government also come on the policy to encourage people to use the solar pv system. However, when choose the solar pv system, need to consider the using solar photovoltaic system disadvantage.

First, the energy density is low, solar panels floor space are large. Although the sun is a tremendous source energy, deliver the total energy of the earth is also great, really exploited is little, the energy density is relatively low. At present, conversion efficiency of the solar panels are still too low, which requires using a large area of solar panels to absorb solar radiation to produce a certain amount of electricity.

Second , it has a great effected by weather change for the electric consumption.
Solar photovoltaic energy source is the sun light radiation, greatly affected by cloudy, rainy and fog days . Due to different geographical location, resources of sunshine is also great difference , and subject to geographical restrictions.

Last ,the home solar power system cost is relatively too high. Using the sun light is free, but a complete set of the system device is too high. For consumer, use the solar pv generation cost is much higher than the public supply system, so there is no cost advantage. It also has been the biggest obstacle to troubled people to install solar power systems. Whether it can save electric charge to Install home solar power system, many people think that is. For the large pv system that is, but for the ordinary households, to invest solar pv power generation have no cost advantage.

Although solar pv power system still have many insufficient, with the increasingly seriousness of energy crisis problem, it will be an effective way to great develop and use the new energy. With the government support and technology development, the advantage will be more and more significant.
