People who pursue oil and have a negative attitude toward solar energy also agree with the fact that the sun is the source of life for all things on earth photovoltaic solar panels. However, this simple fact has allowed solar energy to enjoy the treatment it deserves after a long period of time. The sun is inclusive and everyone is inevitable. It is a matter of course and righteousness, but because of this, no one pays attention.

To date, industries that rely on the sun to develop are not limited to the energy sector. All farms and agriculture and food production rely on the sun for energy. Not only that, but the clothing, football and fossil fuel industries are also related to the sun. The sun supplies energy to everything on earth. The solar energy that reaches the surface of the Earth in just one hour is enough to supply the energy needed for the Earth for one year, as long as it is known to college students who want to be A in physics.

For this reason, photovoltaic power generation failed because it failed to play a substantial opportunity. Photovoltaic power generation has long been regarded as a “gap” energy source, which is an “alternative” energy source that supplements major energy sources such as coal, natural gas and nuclear energy. Everyone in the energy field knows that the resources involved in their industry are limited. One day, at some point, “alternative” energy will become mainstream.

The “sometime” of “someday” of the word “mouth” is now. In recent years, the market and political circles have frequently pointed out the uncertainty of solar energy. The prices of natural gas and oil supply continue to fall, and the price of solar energy fluctuates greatly, but solar energy continues to record and grow. According to data from Solar Power Europe of the European Solar Energy Association, the global installed capacity of solar energy reached 98.9 gigawatts (GW) in 2017, an increase of 29.3% over the total installed global PV installation of 303 GW in 2016 (see table). Including traditional energy and alternative energy sources, photovoltaic power generation accounts for 34% of new investment scale, accounting for higher than other energy sources, which confirms that the solar energy industry has continued to grow in the past decade.

Although many facts prove that photovoltaic power generation costs are declining every year, performance is increasing, and popularity is rising, but global analysts who regularly analyze the future world energy supply structure are constantly underestimating the potential of solar energy.

Why is it so conservative?

As an authoritative international organization, the International Atomic Energy Agency (IEA) regularly publishes reports on various energy development status and future prospects. The data accumulated by the IEA has proven that solar energy has maintained its growth momentum for decades. According to the latest report released in November 2017, based on global data in 2015, the net growth rate of solar energy surpasses that of coal, and together with wind power and other renewable energy, it accounts for two-thirds of the new installed capacity in 2017.

Through its own data analysis, IEA can look forward to the bright future of photovoltaic power generation, but IEA still maintains an extremely conservative attitude towards solar energy.

For example, in 2017, only one year of new solar installations will be added, so the IEA will predict that this year’s development is similar to previous years. Although the solar industry has continued to record high for many years, the IEA report predicts that solar installed capacity will shrink year-on-year. In the past decade, the average annual growth rate of photovoltaic power generation has remained at 44%, but the IEA’s forward-looking report, “Sustainable Development Scenario”, only proposes an annual increase of 140GW. If we look back at the trend of solar energy development in the past 20 years, we should be able to and must present a clearer vision than now, so as to ensure the reality of the solar industry.
