Capacitaciones de Energía Solar en RE+ 2024

Configuraciones de sistemas FV y de Almacenamiento de Energía a Gran Escala

En esta presentación, hablaremos de las configuraciones habituales de los sistemas FV y FV+ de almacenamiento de energía a gran escala. Entre ellas se incluyen los sistemas FV con inversores de cadena, que utilizan una de las distintas configuraciones de cableado de CC: cajas de combinación integradas, cajas de combinación externas y cajas de combinación con arnés de cables. A continuación veremos las configuraciones de inversores centrales, que incluyen opciones con cajas de combinación, arnés de cables y desconexiones de CC externas o integradas. Por último, trataremos los sistemas FV con almacenamiento de energía en baterías, destacando las configuraciones acopladas en CC y CA, incluidos los convertidores de CC a CC.

Opciones Comerciales para Interconectar Energía FV

¿Eres un diseñador, instalador, administrador de proyectos o electricista con experiencia en sistemas fotovoltaicos residenciales y quieres pasar a sistemas de mayor escala? Esta presentación te introducirá en los conceptos importantes que deberás comprender para diseñar e interconectar con éxito sistemas FV a una red eléctrica trifásica. Repasaremos las configuraciones trifásicas más comunes y veremos qué tipo de información se necesita de un sitio para poder completar el diseño de un sistema comercial. También veremos distintos ejemplos de dispositivos comerciales y debatiremos métodos sobre cómo y dónde interconectar un sistema FV en grandes instalaciones comerciales. Además, ofreceremos una visión general de los distintos tipos de equipos que probablemente se vayan a utilizar. Acompáñenos en esta presentación de una hora de duración para obtener una visión general de lo que se encontrará cuando trabaje en sistemas FV a gran escala.

PV + Storage Configurations for Non-fixed Tariffs and Resiliency

Changes to utility tariffs and recent high-profile grid outages have dramatically increased demand for PV systems with energy storage that can provide both economic and resiliency benefits. In this presentation, we will start with the basics of how solar, storage, and the grid interact before exploring design approaches and system configurations that can meet this demand.

Safety First! NFPA 70E

Most of us are familiar with the National Electrical Code (NFPA 70), but did you know this document is part of a trilogy of standards – intended to be used together – to ensure maximum safety for electrical installations? In this one-hour course focused on worker safety, we will look into a different and perhaps lesser known part of this trio: the Standard for Electrical Safety in the Workplace (NFPA 70E). Using this standard as our guide, we will discuss how to identify and assess electrical hazards and risks, and we will review the “Hierarchy of Risk Control Methods” to understand different strategies for hazard risk reduction. We will also review lockout-tagout principles, shock and arc flash boundaries, and we’ll discuss how to select the right PPE for the task at hand. There are many strategies and opportunities for reducing hazards and maintaining a safe working environment for employees, and understanding NFPA 70E is the key to creating safe working areas. 

I-V Curves and Diodes Demystified

I-V curves are the basic graphical representation of performance of PV cells, modules and strings, and they have a lot to tell; PV cells themselves are essentially diodes combined with a photocurrent source; and bypass diodes are fundamental components in silicon PV modules. In this presentation we will discuss I-V curves, how they aggregate, and what different curve shapes indicate, including proper operation – and failures of – bypass diodes. Become a better solar professional by learning how to “think like a PV module” through an understanding of I-V curves and diodes.

2023 NEC® Changes Affecting PV and Energy Storage System

Join a voting member of Code Making Panel 4 for a discussion of changes in the 2023 NEC®. Regardless of the version of the National Electrical Code enforced in your jurisdiction, the Code drives industry-wide best practices and product development cycles of manufacturers; it is critical for installers, designers, manufacturers, engineers, developers, and building officials to stay current. This presentation will focus on critical updates and changes that impact PV system design and installation for all types of applications – including energy storage systems – ranging from off-grid, to interactive PV systems on buildings, up to utility-scale solar farms. There are some great updates that will help reduce system cost while maintaining safety – you need to know what they are to take advantage; there’s also some updates that may end up adding cost – and you need to know the best ways to deal with them. Bring questions if you have them and be ready for a fun time talking Code.

Thermography and PV Systems

Handheld and aerial thermography both play significant roles in PV system operations and maintenance (O&M), including preventative and reactive applications. So much can be easily – and quickly – learned about issues with PV arrays via aerial thermography, whether drone-based or fixed wing (of course it still takes on-site personnel to do anything about it!). And a thermal camera in hand is critical to verifying the integrity of electrical terminations and other equipment – plus they make a great troubleshooting tool. See why IR cameras have become the “go-to” tool for many PV system O&M activities.

Building a Scalable O&M Technician Training Program

The number of operational PV systems continues to grow each year and proper operations and maintenance (O&M) is essential for maximizing system uptime; as a result, O&M has become the fastest growing sector of the industry. This rapid growth has created significant challenges for owners and operators as there is a shortage of qualified technicians that can safely and effectively perform the work. In this presentation we will explore this challenge and how workforce development initiatives, codes and standards, and improved training programs can help the sector to scale up.
