中国光伏产业与太阳能热利用产业的发展模式比较

中国的太阳能光伏产业和太阳能热利用产业近年来都呈现出较快的发展趋势,但二者的发展特征却迥然不同。中国光伏产业虽然起步较晚,但增长速度快,从2003年开始年增长速度都超过100%,2007年成为世界第一大太阳能电池生产国;太阳能热利用产业在20世纪90年代就已形成相当大的规模,年增长速度一直保持在20%左右,2009年中国太阳能热水器产量和保有量分别达到4200×104m2和14500×104m2。中国太阳能热利用产业可谓一枝独秀,占世界总产量的一半以上,且在产业链各个环节发展比较平衡;而中国光伏产业并不具有绝对优势,特别是产业链上游发展比较滞后。太阳能热利用产业整体上是靠国内市场推动发展的,呈现出比较典型的内生型增长特征;而光伏产业表现为"两头在外"的特征,一方面关键的多晶硅材料进口量较大,另一方面产品主要以满足国际市场需求为主。中国太阳能发展政策的目标低、扶持力度小、实质性促进政策少,对太阳能产业发展的促进作用比较有限。此外,市场需求、技术、经济等也是影响产业发展的主要因素。为促进我国太阳能产业的健康发展,建议政府应提高太阳能利用的目标,加快相关立法工作,加大鼓励力度,加强财税支持,注重技术的研发,规范产业发展。

Thermal behavior of a copolymer PV/Th solar system in low flow rate conditions

A simulation model of finite differences describing a water heating system using a Hybrid Photovoltaic-Thermal collector manufactured in a copolymer material and running in low flow rate conditions has been developed. It includes the essential thermal transfers. The thermal and electrical performances of this solar system have been studied. The choice of the material and the structure of the solar collector are described. The temperatures evolution is modeled in various parts of the solar system and the stratification of the tank is shown. Average electrical, thermal and global efficiencies are calculated each month. We note the importance of thermal recuperation which can catalyze the development of such systems. The utilization of a copolymer for the total design of the solar collector has numerous advantages as reducing the weight, facilitating the manufacturing and reducing the cost.     

Solar thermal utilization in China

With the rapid development of the Chinese economy, energy consumption has increased considerably, and this has increased pressure on energy production. On the other hand, this pressure has greatly assisted in the development of the renewable energy in the past two decades.

Issues of most concern and interest, which are resisting a further development of solar thermal utilization, have been identified and discussed. A prediction for the prospect of solar energy thermal utilization in China is also presented.     

Performance analysis of a hybrid solar-hydrogen-retired EV batteries (REVB) energy system with thermal-electrical loops

Utilizing solar energy is an efficient method to provide hybrid renewable energy system with sufficient thermal/electrical energy. Meanwhile, the rapid development of electrical vehicles leads to an excess of retired electric vehicles. As a combination of the abovementioned two conceptions, this study proposed and examined a hybrid solar-hydrogen-retired electrical vehicle battery energy system to meet thermal and electrical loads for small-scale usage. The novelty of this research is delivered as follows: first of all, the proposed hybrid energy system supplies both thermal and electrical energy to small-scale end users; secondly, the retired electrical vehicle batteries are recycling to relieve the pressure of battery demand; thirdly, an energy management strategy to regulate the complicated hybrid energy system is designed. The results show that with assistance of fuel cell as an energy storage unit, solar energy can basically satisfy the annual thermal/electrical load with maximum monthly energy supplement of 1220.43 MJ and 1572.75 kWh, respectively. However, the solar radiation serving as single energy source is not very reliable for large-scale utilization. Although the state of charge does not fluctuate greatly, the small range charge/discharge between 59% and 63% can still guarantee the normal operation of the proposed hybrid energy system.

Product generational dematerialization indicator: A case of crude oil in the global economy

Indicators for sustainable development, such as: Dow Jones sustainability group indices, life cycle index, ecological footprint, sustainability cities index, Well-Being Index, are acknowledged evaluation instruments in the international development policy. They are used to evaluate dematerialization introduced in order to identify environmental efficiency. While these indicators describe the performance of single products on the market or the life style of societies, they do not provide exact information on product (resource) and sector dematerialization, which is one of the major objectives of the current development policies.In this paper, we present a new concept - ‘product generational dematerialization’ (PGD) indicator with the aim of extending the available sustainable development methodology and to cover the existing methodological gap. We show advantages of the practical application of this indicator for management policies on the national and international level by analyzing dematerialization of crude oil in the global economy during the time period 1972–2010.The implementation of the product generational dematerialization indicator for analyses of single products or branches can help to determine consumption areas characterized by the most significant consumption changes, as well as identify necessary actions to be taken to diminish environmental pollution and resource depletion.     

Investigation of functionally graded metal foam thermal management system for solar cell

Concentrated photovoltaic cell (CPV) is a solar energy harvesting device that converts solar energy into electrical energy. However, the performance and efficiency of the CPV are heavily dependent on the temperature. Besides, nonuniformity of temperature distribution on the CPV will lead to thermal aging and affects the cycle life. Hence, an effective cooling system is required to remove excess heat generated to ensure that the CPV operates at optimum operating temperature with minimum variation of temperature. Metal foam is a new class of material that possesses huge potential for thermal management. In this study, a functionally graded metal foam is proposed for the CPV thermal management system. Computational thermal fluid dynamic analysis is conducted to investigate the effect of porosity and pore density on the flow field and thermal performance of the aluminum foam heat sink. The investigation results revealed that 10 PPI functionally graded aluminum foam heat sink with two stages of porosity gradient 0.794 and 0.682 produced the lowest pressure drop and highest thermal performance. Temperature difference of 3.9°C was achieved for a solar cell with total heat generation of 900 W under water mass flow rate of 20 gs⁻¹.
