Developed in partnership with SolarPro Magazine.
Learn large-scale solar design and how to get your projects permitted and installed faster and cheaper. This training covers many types of large solar PV systems, with a heavy emphasis on commercial rooftop systems.
Ryan Mayfield, Solar PV Technical Editor at SolarPro and co-instructor Randy Batchelor, P.E. have developed this course to help experienced solar professionals grow in the industry.
The course materials have been recently updated to reflect ongoing changes in this dynamic topic. During the instructor-led session, both Ryan and Randy will be in the course answering questions on the discussion board and reviewing project work you submit. If you really want to dive in and do a full megawatt design of your own you can. You can even use a real world project and they will review it for you and help you along the way.
After the guided session is over, you will continue to have access to all of the course materials for a full year and can complete the course on your own pace. When you have completed all of the assignments you will be able to print a certificate of completion with CEUs for self reporting.
Learn From The Technical Editor At Solar Pro Magazine
Ryan Mayfield developed this with one goal in mind: to give people who take it a competitive advantage on commercial and utility-scale solar projects.
Course Includes Valuable Tools And Templates
We've lined up some really valuable tools and templates to help you in the course and on future design projects, including access to Helioscope.
Use Software To Layout And Optimize System Designs
Included in the course are extended trial versions of two cloud based PV design software platforms. As we go through the course we will develop a site layout, run energy production models and optimize the design based on the project constraints and to meet code requirements. In addition you will learn to create and check electrical single line diagrams and calculations, and how to develop good notes, details, specifications and scope of work documents. You will not be asked to do any drafting of plan sets, beyond the basic layout, and we will not be teaching any specific drafting software.

Project Lifecycle, Site Assessment and Investigation
In this opening week, we will review the overall lifecycle of a PV project, to first orient ourselves to the various activities that take place, and give context for the lessons in the course. We will then focus on best practices for technical sales, preliminary engineering, site assessment and detailed site investigation (aka, discovery) on large-scale commercial projects. We’ll cover requirements and best practices for siting ground mount, carports and rooftop projects.
Identifying project goals at priorities is also an important activity a the beginning of a project, but we will discuss that in the context of system optimization, later in the course.

Optimizing System Design
Keeping costs down will always be a primary goal for all involved in any PV project. The trick becomes where to cut costs wisely as to impact the overall system performance as little as possible. This week we’ll get into some of the ways we can design our PV systems based on the different criteria we are given.
• Value engineering conductors on dc side
• Array layouts and energy impact
• 1,000 V vs. 600 V
• DC to ac ratios
• Wire management in the design
• Designing with O&M in mind

NEC Application and Utility Interconnection
This week is intended to expand on the NEC applications and interpretations, specifically surrounding the point of interconnection. For the systems we have been talking about, the most common method of interconnection will be supply side connections. We will discuss the basics for interconnecting to medium voltage lines as well for those systems that will be used on dedicated services and installed directly in conjunction with the utility. Topics for this week will focus on:
• Review NEC interconnection rules
• Discuss different interconnection methods
• Review design and drawing requirements

Permitting and Preparing Your Submittal Package
How can you get your permitting done faster and cheaper? That's the multi-million dollar question. In this module, we'll provide tips and tools for getting your projects permitted and approved easier than your competitors. Commonly seen obstacles and associated solutions will be discussed. Getting through the design review process can be time-consuming and add unforeseen costs, so preparing a solid plan set will minimize duplication of work and costs.
