Description
How to design a solar power plant, from start to finish In Step-by-Step Design of Large-Scale Photovoltaic Power Plants, a team of distinguished engineers delivers a comprehensive reference on PV power plants-and their design-for specialists, experts, and academics. Written in three parts, the book covers the detailed theoretical knowledge required to properly design a PV power plant. It goes on to explore the step-by-step requirements for creating a real-world PV power plant, including parts and components design, mathematical formulations and calculations, analyses, evaluations, and planning.
The book concludes with a discussion of a sample solar plant design, as well as tips on how to avoid common design mistakes, and how to handle the operation and maintenance of PV power plants.
Step-by-Step Design of Large-Scale Photovoltaic Power Plants also includes:
Thorough introductions to the basic requirements of design, economic analyses, and investment revenue
Comprehensive explorations of the requirements for feasibility study and grid connection study
Introducing solar resource, and determining optimum tilt angle and module inter-row spacing
Presenting methodology for design of large-scale PV plant, requirements of engineering document, and optimal design algorithm
In-depth examinations for selecting PV module, inverter, string, and DC side equipment
Practical discussions of system losses, as well as estimation of yearly electrical energy production, capacity factor, and performance ratio of large-scale PV plant
Perfect for professionals in the solar power industry, Step-by-Step Design of Large-Scale Photovoltaic Power Plants will also earn a place in the libraries of equipment manufacturers and university professors seeking a one-stop resource for the design of PV power plants.
