PVHardware at a Glance
PVH is a company comprised of experts in solar technology, engineering and construction. PVH was founded in 2011, and is part of Grupo Gransolar, a firm with a vast experience in photovoltaic industry. PVH is headquartered in San Francisco, California, and has an Operations Center in Sacramento, while in Spain it maintains its European headquarters in Alcobendas (Madrid), as well as its principal manufacturing facility in Cheste, near the internaional port of Valencia.
Today PVH’s tagline is “Optimized Solar Solutions”. This optimization is authentic, as PVH’s designs and methodologies have been informed in large part by prior experiences, which affords a variety of perspectives, which include: Design & Engineering, Fabrication, Logistics, Construction, Financing, Operations & Maintenance, and Ownership.
Based on years of global construction and solar experiences, PVH designs optimized solar solutions that are robust, cost effective, and easy-to-build.
From the start, PVH’s structures are designed to the prescriptive requirements of the 2009 International Building Code (25-year structural design life). Every component in the structural system is designed to resist code-prescribed wind pressures calculated from ASCE 7-05 “Minimum Design Loads for Buildings and Other Structures” (referenced by the 2009 IBC).
Because each project is unique, PVH relies on external third-party engineering firms in order to adapt each structure to local codes and norms, in addition to individual project requirements including electrical configuration, geotechnical and topographical studies, seismic ratings, etc.
There are four main focuses with specific norms that have to be met to install the tracker in the corresponding country:
- USA: codes uses are ASCE 7-10 and AISI-S100.
- Europe: the Eurocode
- South Africa: SANS 10160 and AS 4100
- Australia: AS/NZS 1170 and AS 4100.
In the USA, PVH partners with ZFA Structural Engineers in San Francisco, and for the rest of world, PVH utilizes the services of Atos’ Comptency Centor for Mechanical Engineering in Madrid.
PVH’s metalworks is located in the main industrial sector of Cheste (Valencia), Spain, only 800m from the galvanizer, and about 30km from the international cargo port of Valencia. PVH’s industrial facility of approximately 4.200m2 contains state-of-the-art equipment used for transforming high grade steel into PVH’s structural components. Afterwards, the material is sent to a large galvanizer only 800m away, then on to the port.
By having its own metal transformation facility equipped with modern, labor-saving tools allows PVH to be highly competitive, in addition to allowing for tighter quality control, reduced manufacturering time, and greater control of timeframes.
PVH is certified by the European Quality Assurance for the UNE-EN-ISO 9001:2008 and the UNE-EN-ISO 14001:2004 as the Quality Management System and the Environmental Management System.
Nevertheless, for some projects it may make sense to manufacture locally, such as those cases where local content is required. PVH’s supply and manufacturing chain is flexible, and can adapt to contract manufacturing via third-party fabricators and suppliers.
Fixed-tilt racking is available at customer request: email@example.com
Today, large utility-scale solar projects are being devoloped in countries worldwide which means that massive deliveries of equipment must be shipped and delivered in an orderly and timely fashion. In the case of trackers and racking, for very large projects perhaps hundreds of 20- and 40-foot containers, each weighing up to 20Tn, must arrive in a “just-in-time” basis so that work crews have a steady flow of components which must be installed during the months of work required to build out the solar plant.
PVH has dedicated professionals which work directly with leading global shippers in order to provide the best service in the most cost effective manner. During delivery, which can take many months, PVH supervises all aspects of each shipment during its journey from manufacturing to the jobsite, assuring timely deliveries.
As part of a group with a decade’s experience building solar projects, PVH provides its value-added expertise as a turnkey installation service for its trackers and fixed-tilt racking solutions. PVH has experienced professionals who will be on the jobsite from project start through commissoining in the capacity of construction and quality managers, while typcally subcontracting local labor. In addition PVH owns a fleet of equipment, such as pile driving machines, which are transported to each new jobsite.
Controls & SCADA
A tracker’s control system is its most important component since it orientes the photovoltaic modules to the real position of the sun throughout the day in order to maximize the solar electricity generation. PVH develops and maintains its tracker controller and SCADA software inhouse – using open code and off-the-shelf components – while also specifying all components, such as the PLC, meteorlogical sensors, and other critical components. Via its R&D initiatives PVH continues to evolve its control and SCADA systems while always seeking new methods to cost effectively monitor and control utility-scale solar plants.
Atos, a French multinational, has its Competency Center for Mechanical Engineering in Madrid, providing engineering services for companies such as Airbus, Alstom, Talgo, Thyssen Krup, SEAT, and others, employing such advanced methodologies as Computerized Fluid Dynamics (CFD), Finite Element and CAD models, etc.
