PV System Types and Components

 

Basic Level

For those new to the solar industry, this is a great training to jump in with. This brief training will provide you with an overview of the different types of PV systems and component configuration options. Learn to identify and describe the basic functions of the different components in a PV system. You can confidently walk the showfloor and know what you are looking at after you have taken this brief training.

 

2:30 pm – 4:00 pm

Site Analysis and the Solar Resource

 

Basic Level

This training will cover the fundamentals of solar site analysis, covering the most important questions that need to get answered during a first site visit, and analyzing the solar resource available. This information is important to estimate how much PV can be installed in a site, and how much energy that PV array can produce. We will define what to observe, from the structural integrity of the roof and available roof disposition, to the existing electrical distribution panel. We will also explore the various site and shading analysis tools needed to accurately estimate how much energy a PV array will produce based on orientation, tilt angle, and other site characteristics.

 

4:30 pm – 5:30 pm

System Sizing – How Many Watts?

 

Intermediate Level

The size of a system is affected by many different factors: available space, budget, annual electrical consumption, or other electrical service constraints. We will analyze how to take all these into consideration and how to size a PV system accordingly. This presentation will also explore the various ways to calculate a system’s size, including software sizing adjusting for location, type of module, type of mounting, tilt angle, and azimuth.

Array-to-Inverter Configuration

 

Intermediate Level

You know what size system your customer needs, you know what inverter and what modules you want to use. What´s next? In this training we take you through the process of understanding critical technical specifications of these two main components, and how to match them for the most efficient combination and for the specific site you´re designing for. We will touch on maximum and minimum system voltage calculations, string sizing, and array-to-inverter power ratio optimization.

 

3:00 pm – 4:30 pm

OCPDs and Disconnects: which, where, and why. Update to the NEC 2014

 

Intermediate-Advanced Level

The requirements for disconnects and overcurrent protection in PV systems can be complex. Knowing when and where a disconnect is sufficient—or whether an overcurrent protection device (OCPD) is required—is crucial both for system safety and performance. For the NEC 2017 cycle revision a group of subject matter experts delved into updating and rewriting the code sections pertinent to this subject, giving them more clarity of intention and definition. Learn what these changes are, and what are the updated requirements for means of disconnects and OCPDs, and get a head start on what may be in the next revision of Mexico´s NOM-001-SEDE-2018.

 

5:00 pm – 6:00 pm

Verifying PV System Performance

 

Intermediate Level

After a PV system installation is finalized, there is a final step every project manager should be familiar with: it´s time to verify your system is performing to its full capacity and to what´s expected. This is also the case when PV systems have been installed for a long time, and there is reason to believe they´re not performing to their full capacity. This training takes the student through all the factors that affect an installed PV system´s power output. After this training, students will understand the process to estimating performance and be able to use their analysis tools to evaluate the health of PV systems regarding power output.

PV Systems Maintenance Tools and Techniques

 

Advanced Level

This presentation highlights the theory behind, and safe and practical use of, tools and equipment designed for operation, maintenance, and troubleshooting of PV systems. We will cover PV system commissioning, performance evaluation, operations and maintenance, and troubleshooting techniques using tools such as I-V curve tracers, specialized PV commissioning tools, insulation resistance testers, and more.

 

3:00 pm – 4:00 pm

IV Curves Demystified

 

Advanced Level

IV curves are the basic graphical representation of performance of PV cells, modules and strings, and they tell us so much. In this brief presentation, we will review I-V curves and show how they ‘build up’ – from cells to modules to strings – when put in series and or parallel.  Proper set-up and safe operation of curve tracers will be discussed, as well as how to interpret the outcomes.  Also, attendees will see the 5 most common reasons resulting in wacky I-V curves.
