As we know, the main factor of global warming is the increase of carbon emission, the average temperature of Earth has increased by 1℃ in the 20th Century. Maybe you think 1℃ is small, but the slight temperature variation in Earth would lead to huge environmental variation, including longer drought, more frequent prairie fire and…
It has been a long history to adopt LED as lighting source, now let us talk about the LED photochromic. What is the categories and developing history of LED Homogeneous Light ? The earliest LED lighting source which was made by semiconductor P-N junction appeared in the 1960s. At that time, its material is GaAsP,…
There are many categories for LED lighting fixture, such as LED illumination light, LED lamp belt, LED strip, LED inground light, LED flood light and LED garden light, etc. 1. The Structure and Lighting Principle of LED It was in 50 years ago that human being had learnt the basic knowledge that semiconductor materials can…
In the end of June, 2018, Internal Revenue Service (IRS) definitely declared when solar developer can be permitted to enjoy Investment Tax Credit (ITC) by 30% for their solar projects. The 30% Tax Credit would be applied up to the end of 2019, thereafter it would be gradually decreased till 4 years and reach 10%…
Japan’s Ministry of Economy, Trade and Industry (METI) revised its current energy development scheme in August, 2017, It becomes the revise focuses to establish and rebuild nuclear power station, positively develop solar PV industry. As being influenced by unclear leakage accident in Fukushima, Japan’s Ministry of Economy, Trade and Industry hope to accelerate the scheme…
With the development of solar PV industry, by the limitation of electric consumption and transmission, the newly increase solar plants have been slowing in China. At the same time, more and more China’s Solar Companies pay more attention to overseas (outside of China) market, as the geographical closing, the Countries of Southeast Asia have been…
With the global attention to energy and environmental protection increasingly, to push renewable field, especially for the development of solar PV industry has been Countries’ consistent sense. “The Paris Agreement” had been signed in 2015, for solar PV industry, most of enterprises accelerated big investment, to push industrial technology gradually improvement, product cost is decreasing,…
As more and more Countries pay attention to the development of solar energy, solar photovoltaic market has got rapid development in the world in recent years. 1. The History and Current of Solar Photovoltaic Development. The PV development technology can date back to 1839 when a French scientist, E.Becquerel found the photovoltaic effect (PV phenomenon)….
In 7th, December, 2017, according to the report of magazine “WIRED”, if you live in the South of London, the trains that you take might realize to be powered by solar before long. The newest research of Imperial College London and Green Energy Charity found, solar power can provide power supply for the UK’s DC…
In most of people’s impression, African continent is a wide and mystical land, there are fertile land, multifarious wild animal and plant life, and also abundant underground mineral in that land. But maybe some people don’t know its shortage of electric power supply, just 20% residents can get electric power in Africa. It is very…
