Rapid shutdown for PV systems on buildings Expansion of ground-fault and arc-fault requirements Changes that further enable 1,000 Vdc PV systems Updates to disconnect and fuse servicing requirements New standards for field-applied hazard markings Major changes for interconnecting PV systems to the grid New requirements for battery-based PV systems, both stand-alone and interactive Additional changes in Articles 690 and 705, as well as other relevant Articles Join SEI instructors and Code experts Rebekah Hren and Brian Mehalic for a fast-paced and fun three-hour long look at how PV design and installation requirements changed with the adoption of the 2014 Code.

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 “knobs” to turn, any of which can impact the projected production. A fundamental understanding of what goes on “behind the scenes” 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

The step-by-step process walks through all the requirements to design 2011 NEC compliant systems. This process applies to all circuits in grid-direct PV systems, regardless of size. Developed in conjunction with industry experts and extensively peer reviewed, SEI's wire sizing methodology takes the mystery out! Full coverage of all NEC Article 310 and 690 conductor and overcurrent device sizing. Join SEI instructors Brian Mehalic and Rebekah Hren for a three-hour on-demand training training session.

Solar Energy International discusses the following topics: Are you are using the best temperature data to calculate maximum system voltage? Have you reviewed new requirements for labeling, marking and routing conductors? 2011 grounding and bonding requirements have been greatly simplified! Wondering about the DC arc-fault protection devices now required? Don't forget that PV source and output fuses now require disconnects within sight! SEI instructors Brian Mehalic and Rebekah Hren also discuss the following topics: The code-making process, looking to 2014, Articles 90.1(B) and 110.3, 690.4(B) Qualified persons 690.8(B)(1) and (2) Overcurrent devices and conductor ampacity 690.13 Exception 2 - Disconnecting means - all conductors 690.31(E) DC circuits inside a building - Type MC, distance from decking, marking 705.12(A) Size limits of parallel production sources

LinkedIn is a very well established and respected social network with over 259 million users in more than 200 countries. It’s known as “Facebook in a Suit” or the most professional level of Social networking for businesses. LinkedIn is a very valuable tool to find the key decision makers within certain companies. It’s used for finding the best point of contact, gaining familiarity with their background before a call or sales pitch, making such contact much more effective. It’s a social network for professional people. Normally a person would create a LinkedIn profile that would include career details and would update their information periodically as to their current appointment. It would often include a personal statement, personal web address and possibly testimonials from employers and members of staff. If the person has particular interests both professionally and personally they may subscribe to one or more interest groups to receive updates and discussion opportunities.

Facebook is the world’s largest social network. With over a billion users it’s very likely that a proportion of your target customer audience will have a Facebook account. In the ‘Social Media for Business’ course you’ll have been encouraged to research and investigate the preferred social media platforms used by your target audience, so you should have a good idea at this point if Facebook is one of the right platforms for you. Using Facebook in your business is about providing an effective means for your customers to interact with you and connect their friends to your business. Recommendation is the most powerful way a potential customer can be connected to a business, particularly when it’s being recommended by a friend. So if you know that a trusted friend likes a particular brand, you’re much more likely to engage with that brand. Facebook is essentially a platform designed to facilitate social interaction between people with whom you’ve already established some mutual recognition.

Twitter is a social media platform that is used by a wide range of people, from celebrities, who use it to communicate with their fans to companies and brands who can use it to engage their customers and attract new ones. It is also used by people for the social aspect – to chat and share information with friends. In fact, there is no restriction to who or what can have a Twitter account and often a larger company such as Starbucks will also have individual accounts for each product such as Frappuccino’s and even individual store locations. Using Twitter successfully requires a significant commitment of time – being active is key to your success. It’s all about the image you create, and the best‐viewed companies are the responsive ones. Twitter is a real‐time information sharing network where users can share messages, news, images, opinions and links via short bursts of information called ‘tweets’ – these tweets have a character limit of 140 including spaces, which may sound very short but you might be surprised at how much you can get into a little space and how much influence that can have. Even though Twitter is a fairly simple service, it’s still important to understand the mechanics of it thoroughly.
