Learn how to determine the right relationship between a DC solar array size and the inverter output capacity and apply your knowledge to array layouts, module circuit locations, racking consideration, and design optimization issues.

Grid-tied solar will always be impacted by local grid policy, and we take an in-depth look at how. Determine if battery storage is a necessity for a project, as well as how to plan for battery additions down the road.

Selling 30 years worth of electricity to a customer is an expensive proposition. Right-sizing based on local policy and material capabilities can improve project economics, improving payback such that we can accelerate the transition towards solar power.

Learning Objectives

This course is intended to provide you with the following specific knowledge and skills:

Discuss the relationship between DC array size and AC inverter capacity to better understand system efficiency.

Understand how the supply chain can impact system design optimization.

Explore online resources to determine utility requirements and design constraints.

Perform circuit designs for one pallet of solar panels on different kinds of popular inverter systems to improve technical proficiency.

Understand how changes material selection can impact system design for project planning.

Determine a battery size needed for efficient “zero outflow” residential operation to accommodate any utility policy.

Establish a budget and simple payback to improve professional knowledge.

Identify best practices in array layout planning.

This is a two hour program focuses on residential off-grid systems. However, the material components are similar to what would be suitable for commercial battery projects up to 50kW.

Most grid-tied residential solar batteries are small and intended for back-up only. What are the considerations when planning an off-grid residential electrical system?

Growth in battery manufacturing is reducing costs of lithium ion batteries. While off-grid living is still expensive, it has never been more within reach. In certain cases, the cost of grid expansion can result in a happy off-grid solar customer. Learn more about what it takes to size a system for off-grid residential solar living.

This program covers electrical offgrid solar sizing principles and technical component discussion. The goal is to better understand the risks of offgrid living, to improve system reliability and value optimization during the project planning stage.

This program was written by a NABCEP-certified PV installer and mechanical engineer to help technical professionals better understand solar and battery project scope.

Learning Objectives

This course is intended to provide you with the following specific knowledge and skills:

• Identify local solar performance during cloudy weather conditions to improve reliability.
• Evaluate the technical capabilities of off-grid battery inverters to improve project planning.
• Perform a sizing example for off-grid residential new construction to build design skill.
• Understand the design risks of low and high voltage battery banks to improve safety.
• Review component specification sheets to increase technical knowledge.
• Learn how to manage electrical loads and optimize appliance selection.
• Detail wiring diagrams of residential-sized offgrid systems to improve technical proficiency.
• Understand common balance-of-system material to improve system professionalism.

Battery storage is a new, fast-growing energy market. In this live webinar, you will be introduced to residential battery inverter systems with an emphasis on grid-connected systems like the ever famous Tesla Powerwall. This is not a powerwall class, this is a class to help you better understand the capabilities, costs, and design practices of lithium ion technologies as well as associated design and material selection.

This 2 hour program is written to introduce building professionals and engineers to the early sections of National Electric Code. It covers common faults, workmanship best practices, clearance spaces, grounding, and basic electric components discussed in Articles 100-400 of NEC.

Solar and batteries are relatively new industries which require a technical professional to be aware of electrical safety and design risks.
But the specialized sections of National Electric Code are a better understood with general knowledge covered by the introductory chapters of the codebook.

Solar and battery projects are used throughout class as examples, but this class focuses on the introductory requirements of NEC for those projects.
Written for a technical audience, this course is well suited for advancing residential construction knowledge or basic electrical knowledge in general.

Learning Objectives

This course is intended to provide you with the following specific knowledge and skills:

• Detail general vocabulary and balance of system components common to building-based solar and battery storage as they appear in National Electric Code to improve technical knowledge.
• Understand fundamentals of building grounding and electrical fault detection for site safety benefit.
• Review the primary sections of National Electric Code in a comprehensive, sequential manner to improve general electrical knowledge.
• Identify general items which are necessary to install a code-compliant onsite electrical system, using solar and battery projects as examples.
• Understand how code is created from real world design issues to improve basic understanding of how electricity works.
• Review conductor cable jacket types to improve project design and drawings.
• Learn various parts of electric code common to industry solar or electrical examinations.
• Develop an understanding of the general balance-of-system planning requirements for onsite renewable and battery projects.
