课程名称：太阳能基础 课程概述：太阳能是来自太阳的辐射，能够产生热量、引发化学反应或发电。地球上接受的太阳能总量远远超过当前及预期的全球能源需求。如果能够合理利用，这种高度分散的资源有潜力满足未来所有能源需求。国际能源机构表示，开发经济实惠、取之不尽、清洁的太阳能技术将带来重大的长期利益。这将通过依赖本土、取之不尽且大多独立于进口的资源，增强各国的能源安全，提升可持续性，减少污染，降低应对全球变暖的成本。 人类能够利用的太阳能与地球表面附近存在的太阳能量存在差异，受地理因素、时间变化、云层覆盖和人类可用土地的限制。主动太阳能技术利用光伏、电集中太阳能、太阳能热收集器、泵和风扇将阳光转化为有用的输出。被动太阳能技术则包括选择具有良好热性能的材料、设计自然循环空气的空间，以及根据建筑物的位置与太阳的关系进行设计。热质量指的是任何可以存储热量的材料，在太阳能的情况下就是来自太阳的热量。常见的热质量材料包括石材、水泥和水。
Solar energy, radiation from the sun capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy incident on earth is vastly in excess of the world's current and anticipated energy requirements.If suitably harnessed, this highly diffused source has the potential to satisfy all future energy needs. The international energy agency said that the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries energy security through reliance on an indigenous, inexhaustible, and mostly import- independent resources, enhance sustainability, reduce pollution, lower the cost of mitigating global warming. The potential solar energy that could be used by humans differs from the amount of solar energy present near the surface of the planet because factors such as geography, time variation, cloud cover, and the land available to humans limit the amount of solar that we can acquire. Active solar techniques use photovoltaic, concentrated solar power, solar thermal collectors, pumps, and fans to convert sunlight into useful output. Passive solar techniques include selecting materials with favorable thermal properties, designing spaces that naturally circulate air, and referencing the position of a building to the sun. Thermal mass is any material that can be used to store heat- heat from sun in the case of solar energy. common thermal mass materials include stone, cement, and water.
