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

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.

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

We are all created from energy, as well as the objects we hold and the situations we are in, meaning that we are surrounded by both positive and negative energy. We all experience hard times and setbacks, but ignoring the negative energy that may keep resurfacing will greatly affect our relationships and balance, especially of our home. The negative things in our lives can easily take a massive toll on our mental health and emotional state without us even realizing it.  Cleansing our home from negative energies or simply from spirits that have lost their ways towards the light and need help in this transition (which is called "shamanic psychopomp") is a beautiful help we are providing to these souls to find their peace after death. I can assist you, as a shamanic practitioner, to take healing to your home or to any spirits that may be involved.  When is a house cleansing required? *Before moving to a new home, as we the property has surely energy blockages from previous experiences of the inhabitants, likely brought on by the challenges of life. *Any time we need to start a new project or phase in our life and we need to cut old energetic cords that bind us and our space to old happenings. *After personal difficulties or illness *If anyone at home is having problems sleeping. How is the cleansing done? Through incense, sound, light, mantras and a shamanic journey. And whatever my Spirit Allies guide me through my intuition.      By attending to our classes, workshops, 1 to 1 sessions and retreats you agree to our TERMS AND CONDITIONS Payment  Bookings are non-refundable.  Disclaimer  By booking a class or workshop or retreat or 1-1 session -online or any other venues – with us, you release Giada Gaslini, Invisible Caims/School of Shamanism from any liability arising out of any personal injuries, emotional or physical release, death, expectations of results, theft in the venue or damages that may happen to people and objects while attending.

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.
