What's is the equation for AMP?
A=W/V
How would you describe Polycrystalline?
A type of PV cell formed by pouring liquid silicon into blocks and then slicing it into wafers. This creates non-uniform crystals with a flaked appearance that have a lower efficiency than monocrystalline cells.
This device converts DC electricity generated by solar panels into ac electricity used by most appliances?
What is an inverter
What does PPE Stand for?
Personal Protective Equipment
What is the minimum size wattage of a utility scale design for a solar system?
5MW or 5,000KW
What is Watts law equation?
P=V*I

What is one symptom used in diagnosing battery failure?
Increase in battery temperature
What does DC stands for?
Direct Current
What Does ICC stand for?
International Code Council
PV modules are grouped to make what?
Solar Array
This component stores excess energy generated by solar panels for later use, especially in off grid systems
what is a battery?
OSHA requires employers to implement fall-protection systems any time an employee is working at elevations of ?
6 feet or greater
What does AC stands for?
Alternating Current
What does NEC stand for?
National Electrical Code
Solar Cells are combined to make what?

Grid-tied system
Grid-interactive system
How would you describe Monocrystalline?
A type of PV cell formed using thin slices of a single crystal and characterized by its high efficiency.
This bos component ensures that the solar pv system operates safely by protecting it from overcurrent or short circuits?
what is a circuit breaker or fuse.
All personal fall arrest systems must have the ABCs of Fall Arrest Systems:
Anchorage / anchorage connector
Body wear
