This short course is targeted towards beginning users, and will show you in detail how to get started creating accurate production estimates for any size PV system, from residential to large-scale. Learn how to find and import the correct meteorological data, create system variants for any size system, and accurately define the orientation, shading scene, and detailed system losses. By the end of this course you will be confidently simulating production and printing reports to share.

This training includes four (4) three-hour lessons, for a total of 12 contact training hours. Each lesson will include presentations, videos, interactive exercises, and a quiz. 1- Ladder and Lift Safety: In this lesson, we learn about different ladder options and how to choose the appropriate ladder(s) for a PV installation, based on the specific job site and task (accessing different roof surfaces, running conduit, etc.). We discuss how to properly inspect, set up and use ladders, and through interactive exercises we evaluate different installation sites to determine the best location to set up an extension ladder to access the PV array. In the second part of this lesson, we identify equipment and methods for safely lifting PV modules (and other materials) to the roof, including ladder lifts, boom lifts, reach forklifts, scaffolding, and cranes. 2- Fall Protection: Here, we review OSHA fall protection requirements and present different equipment options for working safely AND efficiently on a PV job site. We discuss the differences between fall restraint, positioning, and fall arrest systems; look at different anchor options for roof surfaces commonly seen on PV installations; and via interactive exercises determine where to place those anchors on the roof. 3- PV Mounting Safety: In this lesson, we identify job site hazards specific to PV mounting work, from array layout through securing modules to the racking system. We go step-by-step through a roof-mounted PV installation and call out ways to eliminate and/or control hazards through safe work practices, engineering controls, and personal protective equipment (PPE). Through interactive exercises and videos, we show best practice methods to safely handle PV equipment and manage small parts on a sloped roof. 4- Solar Electric Safety: In the final lesson of this series, we take an in-depth look at electrical hazards specific to PV installation and maintenance work, and discuss the requirements of OSHA, the NEC, and NFPA 70E to assure safe working conditions. We discuss shock and arc flash hazards and identify protective measures (including PPE and lockout / tagout). We dive even further into lockout / tagout and safe electrical testing methods in our interactive exercises and videos.
Modeling is a complicated topic - and performance calculation tools offer nearly endless âknobsâ to turn, any of which can impact the projected production. A fundamental understanding of what goes on âbehind the scenesâ is important to be able to make the right decisions when selecting data, adjusting system assumptions and de-rates, and comparing results so you can be confident when you make a production prediction or design choice. Don't worry, the heavy math is left to the modeling tool! Topics include: Examining and applying the core calculations used to predict production of PV arrays Comparing the various modeling programs on the market, and their different approaches Interpreting simulation results from performance models Relating how system design choices impact the production of the array Join Paul Grana, co-founder of Folsom Labs and the HelioScope modeling and design tool, for an in-depth look at PV system performance modeling in four Parts: Introduction and System Design Environment Assumptions and Irradiance Calculations Module Modeling and System Behavior Simulation Results and Model Comparison

This training includes two lessons for a total of 8 contact training hours. Each lesson includes presentations, field videos, interactive exercises, and a quiz. Lesson 1: Site and Mechanical Hazards- Identify common site and mechanical hazards that workers are exposed to when installing ground-mounted PV arrays, describe ways to mitigate hazards, determine safe working practices and PPE requirements. Lesson 2: Electrical Hazards- Determine electrical hazards on large-scale PV job sites, identify shock and arc flash hazards and implement protective measures, define lockout/tagout methods and principles, examine installation, maintenance, and PV testing hazards.
