[ News ]- Will Solar Power Capture the World’s Energy Market?

Let’s first look at three main problems solar power encountered.

1.How to deal with the storage of solar power?

------One of the biggest problems of solar power lies in that it only can be run in the daytime. So, supporters of fossil energy regarded that the fossil energy should be the "basic" power for electricity generation. Because it can guarantee the energy supply of 24 hours a day.

However, this disadvantages are changing. TheNoor-Ouarzazate, the world's largest solar power center is not the photovoltaic power station. On the contrary, a concentrated solar power system (CSP) is used, which is one great potential system providing energy supplies in the absence of sunshine.

The operating principle is as follows:

Hundreds of reflectors are used to concentrate the sun's energy, heating liquid to produce steam to drive the turbine to generate electricity.The liquid can also be used to melt solid salt stored in the tanks. And the salt can maintain enough quantity of heat. Therefore, CSP can continue generating electricity even if at night.

This is a very guaranteed technology. It is predicted by the global energy organization that more than 11% of global energy will be produced by CSP in 2050.

2. About batteries?

------Another major change is the rapid progress of battery technology.Modern family has been able to buy household battery suits to use with solar panels cooperatively, and the purchasing costs are expected to decrease rapidly in the next few years.

ElonMusk (tesla CEO), famous entrepreneur believes that the demand for electricity around the world, will probably reach 2 trillion sets of large batteries.

3. If it is cloudy, what should we do? 

------We are easy to understand why many hot and sunny regions to select solar energy to meet its country's energy demands. But does solar energy apply in other places?

If we want to work out the problem, Germany is a good example. Although there are not sunny days throughout the year in Northern European, the Nordic countries come out top in the global solar power generation amount.

Germany's solar power generation capacity can satisfy 1/3 of national electricity demand, and in the summer of 2014, Germany's solar capacity even slightly exceeds its demand. This shows us that solar power is not one technology applying only to those sunny countries.

Solar energy is not the only way to meet the world's energy demand, however it can bring us a lot of a lot benefits.With declining cost of solar energy (refer to the previous article) and further restructuring of the world's energy market, solar energy will definitely play a more important role in the global energy market.
