课程名称：太阳能系统设计 课程概述：太阳能系统设计课程在太阳能基础课程的基础上，深入探讨光伏系统的相关知识，包括系统的基本组成部分、功能以及使用简化假设进行的基本系统规模推算。学员应具备一定的电力和能量的基础知识，能够计算站点的能源需求以及在特定地点下光伏系统的能源生产潜力。在本课程中，重点将放在如何将实际地面条件纳入能源生产考量，并在系统设计和设备选择中考虑这些条件。课程结束时，学员将能够将由于阵列设置不佳或遮阴导致的辐照损失纳入设计中，并考虑由于温度变化对模块输出的影响。 课程大纲： 1. **追踪太阳能从源头到面板** - 本模块将对太阳资源进行深入探讨，研究阳光的一些特性，以及光线从太阳到达地球表面时发生的变化。 2. **光伏模块和阵列电路** - 本模块将详细解析光伏模块和阵列的电路及电气特性，学习如何通过模块规格表计算功率，并重点关注在不同条件下模块的运行表现。 3. **不同条件下的光伏系统规模和输出** - 本模块将教授如何在考虑非最佳条件下（如屋顶角度固定或附近树木遮荫）计算辐照损失，并将这些变数早期纳入光伏系统规划中，以提高系统的整体生产效率。 4. **在现实世界条件下的并网光伏系统设计** - 本模块将结合之前内容，进行设备选择和系统规模设计，包括场地勘测的信息收集与记录，以及如何在推荐的系统设计中进行相应的许可申请。 5. **课程顶点项目** - 学员需要设计一个光伏系统，使用商业化组件，并计算在特定条件下的输出。项目要求考虑可用太阳辐射、阵列位置及遮阴导致的损失，设计最佳的光伏模块与逆变器连接配置，并评估系统设计的准确性和安全性。 本课程旨在提升学员在太阳能系统设计方面的专业能力，使其能够在实际应用中进行科学合理的设计和评估。
Name:Following solar energy from source to panel
Description:Welcome to the first module of Solar Energy System Design. In this module, you will be revisiting the solar resource in a bit more depth than the Solar Energy Basics course. This will entail looking more closely at some of the properties of sunlight, and what happens to that light as it travels from the Sun until it eventually reaches the Earth's surface.
Name:PV module and array circuits
Description:We will now look closer at the circuits and electrical characteristics of modules and arrays. In Solar Energy Basics, you used module spec sheets to calculate power using voltage and current. In this module, you will be using those module specifications again, and looking at how the different voltage and current values included are important for determining how that module will operate under different conditions. Lastly, we will be looking at the design of both the internal circuitry of modules, and the circuitry of arrays of modules.
Name:PV sizing and output under different conditions
Description:You calculated photovoltaic system sizes and outputs in Solar Energy Basics based on available insolation. Those insolation values were always based on the assumption of the array being set up at optimal conditions. On-the-ground conditions can often result in variations from the optimal design for capturing all the available insolation, such as the angle of a roof and the direction it is facing being fixed, or nearby trees casting shade onto part of an array. In this module you will learn how to account for the different sources of losses in insolation, because the overall productivity of a system design can change based on the positioning of the array, temperature variations, and shading on parts of the array. These variations in productivity need to be accounted for early in the planning phase of a PV system.
Name:Grid-tie PV System design under real world conditions
Description:In the last content module of the course you will be working on equipment selection and system sizing. The previous modules on array siting, irradiance variability, temperature effects, shading losses, and circuit design will all come into play when you are designing a system. Additionally, you will be looking at site surveying, where those pieces of information are gathered, and permitting, where they are recorded and communicated along with the recommended system design.
Name:Course Capstone
Description:The capstone project of this course will entail applying much of what you have learned in this course. You will need to design a PV system using commercially available components and calculate it's output under site specific conditions. You will have to account for the available solar radiation and losses due to the positioning of the array as well as due to shading. You will also need to design an optimal configuration to connect the PV modules with an inverter. Finally, you will evaluate a PV system design for both accuracy and safety.
Solar Energy System Design builds upon the introduction to PV systems from Solar Energy Basics course, which included basic system components and functions, as well as some basic system sizing using simplifying assumptions. You should at this point have a basic understanding of electrical power and energy, be able to calculate the energy needs of a site as well as energy production potential for a PV system at a given location under optimal conditions. Much of this course will focus on incorporating on the ground conditions into energy production considerations, and how to account for these conditions in system design and equipment selection. By the end of this course you should be able to incorporate losses in irradiance due to array setups with less than optimal positioning and/or shading, and account for variations in module output due to temperature variations in your system design.
