Design of 1MW of Ground Mounted Solar Power Plant Part 1

Designing a 1MW solar power plant requires much more than just knowing solar panels and inverters — it involves site analysis, accurate electrical sizing, and detailed AutoCAD layouts that meet professional and bankable standards.

This course is your complete practical guide to mastering solar power plant design. You will learn how to perform site survey and feasibility studies, calculate and size all electrical components (DC/AC side), and create professional site plans and solar array layouts in AutoCAD.

By the end of this course, you will be able to deliver real-world solar project documentation that clients, consultants, and funding agencies demand.
