Basics
The unit of power commonly used to measure the output of a solar panel.
What is a watt?
This tool is used to secure solar panels to the roof structure.
What is a mounting bracket?
This federal program provides tax credits to homeowners who install solar systems.
What is the Investment Tax Credit (ITC)?
If a solar panel system is underperforming, this device is the first to check to ensure it is converting DC to AC properly.
What is the inverter?
This code is essential for solar electricians to ensure installations meet electrical safety standards, including wire sizes, grounding, and system integration.
What is the National Electrical Code (NEC)?
This part of the solar panel is made of silicon and is responsible for converting sunlight into electricity.
What is a photovoltaic cell?
This is the type of inverter typically used in residential solar installations.
What is a string inverter?
In some states, homeowners with solar systems can sell excess energy back to the grid through this arrangement.
What is net metering?
The most likely cause of a solar panel system's output decreasing is this environmental factor affecting panel efficiency.
What is shading?
Solar electricians must follow this specific part of the NEC that deals with the installation of photovoltaic systems.
What is NEC Article 690?
This is the best location for installing solar panels to maximize energy production.
What is a south-facing roof?
This personal protective equipment (PPE) is essential for protecting the hands of a solar electrician when working with electrical components.
What are insulated gloves?
This financial option allows homeowners to install solar systems with no upfront costs and pay for the system over time.
What is a solar lease or power purchase agreement (PPA)?
A sudden loss of power in a solar system may be caused by this protective device shutting off after detecting an issue.
What is a circuit breaker?
The requirement for proper grounding of solar panel systems, including all metal parts, is outlined in this part of the NEC.
What is NEC Article 250?
This device converts the direct current (DC) electricity generated by solar panels into alternating current (AC) for household use.
What is an inverter?
Before beginning a solar installation, this action must be taken to ensure there is no live current in the system, preventing electrical hazards.
What is de-energizing or disconnecting the power?
This government entity sets regulations and standards for residential solar installations to ensure safety and efficiency.
What is the National Electrical Code (NEC)?
This is a common cause for solar panel underperformance, where the panel is covered in dirt, leaves, or debris.
What is soiling?
This NEC standard ensures that solar systems are safe during installation and operation by specifying the maximum allowed voltage for a residential system.
What is 600 volts?
This type of battery is most commonly used in modern solar installations due to its efficiency and long lifespan.
What is a lithium-ion battery?
Solar electricians must install this safety feature to ensure that a solar panel system can be shut off quickly during emergencies.
What is an emergency disconnect switch?
This government agency is responsible for implementing policies and regulations related to renewable energy, including solar power.
What is the U.S. Department of Energy (DOE)?
This device is commonly used by solar electricians to measure the voltage and current of a photovoltaic system during troubleshooting.
What is a multimeter?
To pass the NABCEP PVIP exam, installers must demonstrate knowledge of this regulatory document that dictates the proper wire gauge for solar installations based on amperage.
What is the NEC (specifically Article 310 for conductors)?
