Ⅰ SIGNIFICANT ADVANTAGES
Solar power has the following advantages over traditional fossil energy sources: 1. Solar energy is inexhaustible and renewable. 2. Clean without pollution or noise. 3. Solar systems can be built in a centralized and decentralized manner, with large selectivity of location, such as home roof installation, farm floor installation, and flexible and diverse site selection. 4. The formalities are relatively simple. 5. Construction and installation project is simple, construction cycle is short, can be put into production quickly.
Ⅱ POLICY SUPPORT
Against the backdrop of global energy shortages and increasing climate change, countries have introduced policies to transform energy development patterns and promote energy development in a green direction, and solar energy has been given attention for its renewable, large reserves and pollution-free advantages.
In recent years, the United States, Germany, Italy, France and other countries have given relatively strong support to photovoltaics. By promulgating new decrees or implementing action plans, they have set development goals and used fixed feed-in tariffs, taxes and other measures to stimulate the development of photovoltaic industries. Countries such as Austria, Denmark and Norway do not have uniform photovoltaic development goals or mandatory requirements, but rather support photovoltaic R&D projects through a number of loose initiatives.
China, Japan and South Korea all set clear photovoltaic development goals and reduced installation costs through subsidies. China has also implemented a large-scale “photovoltaic poverty alleviation” program to implement photovoltaic roofs in impoverished areas. The government has subsidized the installation of photovoltaic projects to a certain extent, reducing the installation cost of farmers and shortening the investment recovery period of farmers. Similar projects exist in Switzerland and the Netherlands, where the Federal Government of Switzerland classifies projects into various types based on the installed capacity of the installation projects and grants different types of subsidies. The Netherlands, on the other hand, directly grants PV installation users 600 euros of installation funds to stimulate the growth of PV installations.
Some countries do not have specialized PV programmes, but rather support the PV industry through renewable energy programmes, such as Australia and Canada. Malaysia supported the development of photovoltaic projects, including the development of the Energy Fund, through the collection of fees from electricity prices, and since its implementation, the photovoltaic industry has grown rapidly from 1MW to 87 MW per year.
Thus, energy, as an important material basis for national development, is essential to safeguarding the economic and social development of a country. Compared with other energy sources, solar energy has the advantages of pollution-free, wide distribution and abundant reserves. Therefore, countries around the world formulate policies to develop the solar photovoltaic industry.
Ⅲ USERS’S BENEFITS
Photovoltaic power generation is based on solar power, sounds free of charge, and certainly attractive. Secondly, the use of photovoltaics actually reduces the peak electricity price, combined with policy subsidies, can invisibly save a lot of living costs.
Ⅳ GOOD PROSPECTS
Solar power generation is one of the main forces of energy transformation, and its prospect far exceeds the heat and scale of real estate. Real estate is an economic model created with time cycle laws. Solar power will be a lifestyle that society must rely on for large production.
