Los sistemas fotovoltaicos (PV) solares pueden proporcionar beneficios significativos a los propietarios de viviendas, dueños de propiedades comerciales, y a jurisdicciones porque reducen los costos de energía, contribuyen a la seguridad y fiabilidad energética, reducen la contaminación y promueven la energía limpia. Sin embargo, la instalación incorrecta de sistemas PV solares puede resultar en un mal rendimiento o en peligros graves para la seguridad que opacan estos beneficios.


Para las empresas de energía solar y las jurisdicciones responsables de garantizar la calidad de las instalaciones PV solares, comprender las deficiencias comunes es fundamental para asegurar un rendimiento energético óptimo y para reducir riesgos.

A man is installing solar panels on the roof of a building.

Como el principal proveedor de garantía de calidad solar en los Estados Unidos, IBTS ha recopilado datos extensivamente de miles de instalaciones solares en todo el país a través de nuestro software de Gestión de Calidad de Inspección de Campo (FIT-QM). Sigue leyendo para conocer las deficiencias de instalación más comunes, su impacto en el rendimiento y la seguridad de los sistemas PV solares, y cómo abordarlas y prevenirlas en tus instalaciones.


Problema #1: Etiquetado incorrecto del sistema
El etiquetado adecuado de los sistemas PV es requerido por el código por una buena razón. Un etiquetado incorrecto puede carecer de advertencias adecuadas sobre peligros y crear complicaciones para los técnicos de mantenimiento, así como para los primeros respondedores. Nuestros expertos en calidad solar a menudo encuentran problemas como etiquetas ilegibles o descoloridas, valores incorrectos o advertencias de peligro que faltan. Para evitar estos problemas, proporciona a tus instaladores etiquetas que resistan el entorno y asegúrate de que etiqueten correctamente todos los componentes, evitando unas escritas a mano.


Problema #2: Gestión de cables
Una gestión adecuada de los cables es esencial para garantizar un sistema solar PV seguro, fiable y de alto rendimiento. Sin embargo, nuestros datos muestran que fallos en la gestión de cables ocurren en el 38% de los proyectos PV instalados a nivel nacional. Nuestros expertos frecuentemente encuentran cables colgantes o mal gestionados, soldaduras y terminaciones incorrectas, radios de curvatura excesivos y conectores mal instalados durante las inspecciones, todo lo cual puede comprometer la seguridad y el rendimiento del sistema.


Problema #3: Componentes del sistema y de equilibrio
Componentes como recintos, penetraciones, anclajes de seguridad y conexiones de conductos ayudan a garantizar la fiabilidad y la vida útil de los sistemas PV al apoyar a que sus circuitos estén protegidos del ambiente externo y que los riesgos potenciales de seguridad se reduzcan. Nuestros expertos en calidad citan recintos degradados y conexiones comprometidas como hallazgos comunes, señalando que estos pueden llevar a vulnerabilidades y disminuir el rendimiento, la seguridad y la longevidad del sistema.


Problema #4: Conexión a tierra del sistema y equipos
Una conexión a tierra adecuada es esencial para la seguridad, estabilidad y fiabilidad de los sistemas PV, sin embargo, es común encontrar sistemas que no cumplen con los estándares de conexión a tierra, como aquellos con identificación incorrecta de los conductores, cables desconectados y conexión a tierra de módulos o bastidores. Estos problemas afectan el rendimiento del sistema y pueden poner en riesgo de descarga eléctrica a instaladores, inspectores, contratistas y ocupantes.


Prevención de deficiencias comunes mediante la gestión de la calidad


Además de identificar y abordar estas deficiencias comunes en instalaciones individuales, es crucial comprender y abordar las causas fundamentales que contribuyen a problemas recurrentes. Estas pueden variar, pero pueden incluir una formación, orientación y supervisión insuficiente para los nuevos instaladores; políticas y procesos empresariales inconsistentes; y la falta de evaluaciones de terceros.


Implementar un enfoque estructurado y sistemático de gestión de la puede ayudar a mejorar los procesos en cada etapa, asegurando instalaciones consistentes y correctas que prevengan costosas llamadas de retorno y posibles problemas de responsabilidad.

MIAMI, FL— What does it take to deliver resilient housing at scale in the Caribbean? That question was at the center of a panel featuring James Turner, IBTS Director of Federal Programs, during the 10th Caribbean Infrastructure Forum (CARIF) in Miami. The event brought together government officials, developers, investors, infrastructure leaders, utilities, development finance organizations, and public-sector decision makers from more than 30 Caribbean nations and territories to discuss the region's infrastructure priorities and investment needs. James was featured on stage for the "Delivering Affordable and Resilient Housing in the Caribbean" panel discussion, alongside Bermuda housing leader Jeane Nikolai and Caribbean business executive André C. Walcott. The discussion focused on a challenge shared across the region: how to provide safe, affordable housing while strengthening communities against hurricanes, flooding, and other natural hazards. Drawing on IBTS' 5-decade-long experience supporting the US Department of Housing (HUD), as well as our experience in FEMA-funded housing and recovery programs, James emphasized that resilient housing is about much more than construction. Successful programs depend on strong building codes, qualified workers, reliable materials, effective quality assurance, and the systems needed to move projects from funding to implementation. Fellow panelists also shared their interesting perspectives based on their experiences. Jeane Nikolai stressed that homes must be built to withstand the region's climate conditions and backed by dependable warranty terms, noting that a lack of such options can narrow the housing choices available. Resilient construction, she emphasized, is essential to protecting both the homes themselves and the people who live in them. André C. Walcott underscored the importance of consistent building standards to ensure quality construction, along with the need for qualified, well-trained personnel and approved building materials, all of which contribute to safer, better-performing homes. The discussion and audience questions made one point clear: housing shortages are a shared challenge across countries, but the obstacles to meeting housing goals vary from place to place. Funding is a significant concern, but it is not the only driving factor in every case. The conversation reinforced why organizations such as IBTS are needed. Across the Caribbean, governments are investing in housing, infrastructure, and resilience, but many face common implementation challenges, including regulatory requirements, workforce shortages, compliance oversight, and program delivery. IBTS helps bridge those gaps via program management, building code compliance, quality assurance, inspections, resilience planning, and related technical services. Beyond the panel discussion, CARIF provided an opportunity for IBTS to engage directly with government representatives, infrastructure agencies, development institutions, utilities, developers, and private-sector partners working throughout the Caribbean. These conversations highlighted a growing focus on turning funding and policy commitments into real-world projects that strengthen communities and improve long-term resilience. Reflecting on the experience, James noted: "I was honored to participate in discussions with a group of solution-oriented leaders and professionals addressing the critical needs of the Caribbean. I look forward to continuing these important conversations and turning the concepts into actionable implementations." For IBTS, the message from CARIF was clear: resilient housing requires collaboration, practical implementation, and a commitment to quality at every stage. As Caribbean nations continue investing in their future, IBTS remains committed to helping communities transform plans, funding, and policy goals into lasting results.

IBTS supports regional collaboration on affordable resilient and code complaint housing
July 21, 2026
The Institute for Building Technology and Safety has completed energy-efficiency, health and safety improvements in 103 Puerto Rico homes through a federally financed weatherization program, exceeding its goal of 100 households in about six weeks. The nonprofit organization, known as IBTS, managed operations and coordinated the latest phase of the U.S. Department of Energy’s Weatherization Assistance Program in collaboration with the Puerto Rico Department of Economic Development and Commerce’s Energy Public Policy Program. Weatherization programs are intended to reduce household energy costs by making homes more efficient while addressing conditions that can affect residents’ health and safety. The Puerto Rico initiative prioritized low-income families, older adults and people with disabilities, according to IBTS. The organization did not specify the individual improvements made in each home but said the work was intended to increase comfort, improve living conditions and strengthen resilience. IBTS handled project management, inspections, quality assurance, regulatory compliance, document control and staff training, the organization said. The project also reported a 98% satisfaction rate among participants. “This program demonstrates what is possible when federal resources are translated into practical, measurable improvements for families and communities,” said Agnes Crespo-Quintana, IBTS’s Caribbean regional director. Alvin Miranda-Colón, manager of the Weatherization Assistance Program, said the initiative was intended to make energy more affordable while supporting sustainability and community resilience. IBTS said the project required coordination among government officials, contractors, auditors, inspectors, technology providers and participating communities. The organization said that work also developed procedures, trained personnel and expanded institutional capacity that could be used in future federally financed energy, housing and infrastructure programs. Judelly Hernández-Morales, the IBTS project manager, said cooperation between the public and private sectors helped translate federal funding into improvements for participating households.
