This program is designed for experienced solar system designers, project managers, engineers, and experienced field technicians seeking to advance their technical skills. It is particularly suited to those who are presently working in the grid-tie and battery-based residential markets and who intend to enter the small-commercial (10kW-1Mw) market. This training is also suited to commercial-only electrical contracting businesses interested in operating in the commercial solar market.
Topics Covered
Introduction
The technical training specialists at SolarPro magazine will bring together some of the country's premiere PV experts, developing a comprehensive slate of advanced system design and installation workshops. The program is intended for experienced (NABCEP or equivalent level) PV designers, engineers and installers currently working at or aspiring to the 1 MW project size. Subject matter focus is progressive, moving logically from pre-design to design to installation, permitting to inspection, commissioning to O&M. Technical emphasis will be placed on optimization at all stages of project development and deployment with special attention given to safety concerns and code compliance.
Course Objectives
It is the goal for the participants of the Pro Track to feel comfortable scaling up from large residential and small commercial projects to systems in the 100s of kW and approaching 1MW. The information presented shall allow installers and designers to immediately apply the techniques and processes given throughout the sessions. Participants will also be exposed to resources to help them further after leaving the classroom and encountering specific situations on the job. Each training session is aligned with the NABCEP Job Task Analysis to assist those seeking education toward their NABCEP Certification.
Day One
Session One: Site Evaluation
A site evaluation is the first step in establishing a good overall PV design. Information that is incorrect or missing results in return trips to the site or additional time tracking down the required information. This session will focus on the best practices used in developing a complete site survey for a commercial application. An emphasis will be placed on establishing a process to gather information, shading analysis, structural components to look for, electrical service considerations and roof evaluation. (1.25 hours)
Session Objectives
- Predict solar resource through shading analysis and measurements
- Establish a process to effectively and completely gather necessary information
- Identify structural components within the building that may restrict the installation
- Determine best locations for BOS
- Identify the best POCC and conduit routing and at least one alternate
- Organize the site survey information for future reference
Session Two: System Design: DC Side Components
Designing the PV array will involve numerous components. It is important for the designer and installer to understand the requirements and limitations of all the components involved. This session will focus on specifying the components used on the DC side of the system. Methods involved in choosing PV modules, racking systems, combiners and disconnects will be explained. Roofing considerations, especially roof penetrations and proper sealing methods, will be included. (1.75 hours)
Session Objectives
- Recognize the components required to complete the DC installation
- Identify the allowances/limitations of combiners and disconnects
- Determine the best racking solution for the roof surface
- Generate a list of components required
- Identify proper equipment selection based off applicable codes and safety issues
Session Three: System Design: DC Side Calculations
In order to ensure a smooth installation, the up-front calculations need to be done efficiently and correctly. This session will continue with the DC side focus be examining the calculations required. Methodologies used to comply with NEC voltage and current requirements will be presented. Participants will have a better understanding of the calculations used, how to apply them and methods to properly size conductors and OCPD. Safety and code considerations for field crew will be identified and discussed. (1 hour)
Session Objectives
- Establish design parameters for component (modules, wire and fusing) derating Calculate temperature corrected PV voltages
- Select proper size conductors based on conditions of use
- Assess the voltage drop on all circuits
- Address the need for DC aggregation and the proper use of re-combiner boxes
- Identify proper codes during design for safety
Session Four: System Design: AC Side and Interconnection
The AC side of the system has very specific considerations when compared to the DC side. Inverter selection (central vs. string vs. micro), inverter location, the point of common connection (POCC) with the utility and voltage drop considerations are some of the design elements this session will evaluate. The importance of array to inverter matching will be examined in addition to properly matching the inverter(s) to the utility service available. Some of the safety issues that are commonly found in larger commercial systems will be addressed. (2.25 hours)
Session Objectives
- Compare different inverter types (central/string/micro) for a system design
- Recognize the effects of PV array to inverter sizing
- Identify the method of making the POCC
- Identify safety hazard with increased voltages
- Identify proper equipment selection based off Code and safety issues
- Calculate conductor and OCPD required per NEC
- Balancing multiple inverters on a commercial service
Session Five: PV Plan Sets
The diligence used to properly design the AC and DC sides of a PV system need to be shown though the use of proper plan sets. Plan sets will be used in the permitting process, construction and inspection. This requires attention to many details so that all parties can properly perform their tasks as it relates to the PV system. This session will establish the required levels of information needed in order to convey the design to all parties. (1 hour)
Session Objectives
- Establish the requirements for a good plan set
- Determine the portions of the installation that require additional details
- Demonstrate effective ways to relay information on a drawing set
- Identify potential software programs that can be used
Day Two
Session One: Permitting and Inspection
A project's success can very well be judged by the ability to move through permitting and inspection. While they are very different processes that occur at different ends of the project's time line, they are very much connected. This session will focus on the work done with the Solar ABCs and their efforts to streamline the permitting process. Topics will include information to compile for jurisdictions, how to properly obtain and report information and field inspection guidelines. (2 hours)
Session Objectives
- Organize individual data sources into a single document
- Identify common permitting requirements and obstacles
- Standardize the permitting and inspection process
Session 2: Code Violations
In an effort to minimize unexpected costs and performing redundant tasks, every effort should be made up front to minimize code violations (NEC and IBC). This session will cover commonly seen code violations and steps installers can take to avoid such mistakes. Issues such as wire management, proper labeling, grounding, equipment selection and location will be covered. System design issues that can help mitigate in the field problems will also be covered. (1 hour)
Session Objectives
- Identify common code mistakes made in the field
- Modify installation practices to avoid violations
- Create methods during system design to address potential problems
- Establish accepted practices for difficult installation issues (grounding)
Session Three: Commissioning and Acceptance
Proper commissioning allows integrators to establish a known baseline for the installation on day one. This information can be used to validate future production from the array under a variety of conditions. This session will allow integrators to establish a plan for project commissioning. Topics will include how to identify proper tests to perform, proper commissioning sequences, methods to record data and ways to validate the data taken. (2 hours)
