Introduction
2700多年来,太阳能一直被用于烹饪、供暖和其他重要应用,从而更有效地创造生活。太阳是强大的,一直是人类的重要资源,太阳的能量被认为是取之不尽用之不竭的。太阳能对环境具有积极影响,并补充了环境因素。
最近,由于化石燃料对环境的过度使用,太阳能项目的规范受到了欢迎。随着创新技术的应用,太阳能项目逐渐发展起来。太阳能的可再生项目是指从可持续资源中收集的能源。这些资源包括风、地热、阳光、雨水、海浪和生物量。
What is solar energy?
太阳能是指转换成电能的能量,有助于节省电力和电费。进入地球大气层的大部分阳光以红外辐射和可见光的形式出现(Salam&;Khan,2018)。
太阳能的主要动机是将太阳能加热和冷却(SHC)、聚光太阳能发电(CSP)和光伏发电(PV)转化为电力。
Figure 1: Off-grid solar power system
关于太阳能的一个主要事实是,一小时的阳光相当于地球一年的能量。太阳能项目发展迅速,因为太阳能电池板在启动电力时不会产生任何污染。太阳是一种强大的资源,它的光在10分钟内到达地球大气层9000万英里(Kassem,Çamur&;Alhuoti,2020)。世界上最大的太阳能发电厂位于莫哈韦沙漠,占地约1000英亩。使用太阳能的主要原因是,与化石燃料相比,太阳能更实惠。
Advantages and disadvantages of solar energy
Advantages
太阳能是一种可再生能源,可在世界各地使用。地球可以利用阳光超过50亿年,在这段时间里,阳光得到了有效利用,对环境产生了积极影响。
太阳能有助于将电费降至最低,因为从太阳收集的能量有助于形成电力(Irfan等人.2020)。节省电费完全取决于热量或电力的使用以及太阳能系统的大小。
在维护太阳能电池板或系统时,不需要巨大的成本。维护成本非常实惠,最可靠的太阳能电池板生产提供20-25年的保修
太阳能行业的技术因素正在不断发展和进步,这一点在未来将得到加强(Salam&;Khan,2018)。量子物理学的创新有助于最大限度地提高太阳能电池板的效率。

Disadvantages
太阳能的一个主要缺点是它依赖于气候。在阴天或冬季,太阳能电池板的效率会下降,这会给发电带来困难。
太阳能的储存非常高,初始购买成本过高。在面板充电时使用合适的电池可以有效地降低存储成本。
太阳能电池板(光伏电池板)需要巨大的空间来安装。许多屋顶没有合适的结构来安装太阳能电池板发电。
Types and uses of solar energy
太阳能主要分为两种主要类型,这取决于能量的转换及其转化为的能量类型,基于能量转换模式的两种关键类型的太阳能是被动太阳能和主动太阳能太阳能太阳能热能光伏太阳能和聚光太阳能是基于将太阳能转换为另一种形式的能量。在没有机械装置帮助的情况下捕获太阳能是指被动太阳能。
Figure 3: Solar thermal energy
将太阳能转化为热能称为太阳能热能。用于发电的太阳能热能有助于集中太阳能(eia 2022)。获得的太阳能用于各种用途。它用于加热水;太阳能毯子被用来给游泳池保暖。太阳能也用于烹饪,所获得的太阳能有助于对可食用产品进行加热、烹饪和巴氏杀菌。太阳能炊具用于烹饪。
Solar energy project
太阳能项目是与功能太阳能加热模型的效率相关的实验。这个实验被认为是科学展览中可以准备的最简单的实验之一。
然而,由此产生的结果可能会根据该地区的位置、风速和天气而有所不同。因此,该实验主要考虑在封闭的室内环境中进行(dundeesciencecentre 2022)。这个实验需要一个木制支架、温度计、衬纸、凹面镜、聚光镜和管子。个人需要安装支架,并用一张黑纸卷起管子。然后,需要将管子连接到凹面镜上,使阳光集中在一个特定的方向上。然后将管子装满水,并在30分钟后记录温度。温度上升决定了通过凹面镜到连接管的热传递效率。

Conclusion
太阳能与将太阳能转换为不同类型的能源相关,从而有效地获取可再生能源。以光和辐射的形式穿过地球大气层的阳光被人类和植物利用。现代技术的使用引入了太阳能电池板,有助于将太阳能转换为烹饪、供暖和发电等各种用途。
