Renewable Resource- Development of Solar Power
With the aggravation of global environmental pollution, people have growing awareness in environment protection and higher requirement on energy resources. Looking for new energy resources has become one of the most pressing problems confronted by humans.
Indispensable to our life, electricity is mainly produced from thermal, hydro, nuclear and wind power. Thermal power consumes fossil fuels which has limited stock on the earth and produces harmful emissions and pollutants to the environment. Hydro power needs to consume certain lands, which may cause damage to the ecological environment. Moreover, water resources are easily affected by seasons change. Nuclear power is clean normally but the consequence was terrible once leakage happens.
Solar energy is the most primitive resource. Almost all the other energy resources on the earth directly or indirectly come from solar energy which is abundant and widely
distributed. Safe and clean, solar energy is an ideal energy resource. Solar photovoltaic (PV) is a technology that directly transfers solar power into electricity through work of
PV panel modules and battery device. Featured by high safety and reliability, it is not inclined to be influenced by external factors and thus welcomed by clients.
Solar PV technology involves distributed system and centralized system. Distributed PV systems are mainly installed on the surface of buildings to solve electricity supply to
residents nearby; it can also be connected to grid system and increase revenue through supply of surplus power. This method not only solve the electricity problem of remote areas and can also save ground lands compared with solar plants. Centralized PV system like large scale solar plants are mainly located in desert and waste lands, which are connect to grid system and transmit power to terminals. It makes full use of land resources and plays some role of resisting winds and fixing sands.
Although emerged early with so many advantages, solar PV system wasn’t used widely due to its high cost. In recent years, with cost reduction of solar panels, expansion of
application fields and encouragement of government policies, the demand of solar PV market is continually increasing.
As data shows, in 2018, globally installed PV capacity was about 100GW, total value $52.5 billion and capacity of 10 countries exceeded 1GW. At present, the top three of cumulative installed capacity are China (176.1GW), the United States (62.2GW) and Japan (56GW). Asia dominates the global solar PV market, and other regions are expected to grow continually with market demand in the future.
