Analyze the market prospect of the solar
Solar photovoltaic technology and LED lighting lies both with the perfect combination for the direct current, low voltage and can be matched and so on. Combination of the two does not need the inverter to convert solar energy (PV) cells produce direct current into alternating current. Thus greatly improve the overall lighting system efficiency. At the same time by means of grid technology or rechargeable battery discharge, the advantages are obvious. In order to fully explain the matching between the two, for which we establish the following model for analysis, were selected halogen, compact fluorescent lamps (CFL), linear fluorescent (LFL) and four kinds of light sources used in PV-powered LED lighting system for comparison. The overall efficiency of different systems seems to be assessed. In order to determine the factors that affects the efficiency of the system and various applications in the optimal system configuration.
Solar LED lighting products are a new generation of green lighting products, its main components include: First solar cell (PV technology), second semiconductor light source (LED). And it can also promote the LED flashlight developing.
Since 1997, the future prospects for the development of photovoltaic technology have been an increasing number of national governments and the financial sector (such as the World Bank) are recognized. Many developed countries and regions have developed photovoltaic development plans. The U.S. plans to cumulative installed 416GW in 2012 (U.S. Department of Energy plan, roof plan with million). European Union plans to cumulative installed 617GW (Renewable Energy White Paper) which 317GW installed within Europe, 3GW export and so on. Expected the next 10 years the production of PV modules will be 20% to 30% of the rate of development, by 2011 global PV installation rate 312kMW, PV turnover will increase to $ 18.5 billion. The market will gradually from remote complementary regional and rural areas of alternative energy transition energy the whole society. To the mid-21st century, solar photovoltaic power generation will reach the world’s total generating capacity of 15% to 20%, to become one of mankind’s basic energy.
The same as the solid-state light emitting diode LED rise, was that really ignited the “green light” a brilliant slogan. “Green light” is the slogan of the early nineties the international energy conservation. Environmental protection says the image of the lighting system, currently in power consumption. The large proportion of electricity for lighting, green lighting, energy-saving research are more and more attention. LED is in such a form developed. Combined with new materials and semiconductor industry technology, LED, especially white LED luminous efficiency on the rise, the price also will be on the decline, the use of LED characteristics, combined with new technologies related to the present has been developed for different occasions and purposes lighting system. It can be said in the lighting market potential will be immeasurable.
