Sunny Side Up
Which organization develops standards commonly used in the solar industry?
ANSI
The PV system has four main components: Panels, Batteries, Charge Controller and what?
Inverter
The individual units inside a solar panel that generate electricity are called these.
Solar Cells
This type of inverter is installed on each individual solar panel.
Microinverter
6 400-watt panels have a total rated output of this many watts.
2,400 watts
What is the primary purpose of codes and standards in the solar industry?
Protect the health and safety of the public
Wiring solar panels in parallel increases the
Amperage
This device protects solar circuits from overcurrent.
Fuse or Circuit Breaker
If a panel produces 75 volts and 15 amps, its power output is this many watts.
1,125 watts
Ten 50-volt panels wired in series produce approximately this voltage.
500 watts
What does energy efficiency mean in a building?
Reducing a building's energy consumption
What component stores electricity for later use?
Battery
Energy used over time is commonly measured in these.
kilo-watt hours
Increasing voltage while keeping power constant will generally cause current to do this.
Decrease
A 9 kW solar system producing for 5 peak sun hours generates about this many kWh.
45 kWh
What are solar panels (photovoltaic panels)?
These devices/modules convert sunlight into electricity.
This type of electricity is produced directly by solar panels.
DC
Connecting solar panels in this configuration increases voltage.
Series
NEC requires exposed metal parts of a PV system to be connected to this for safety.
Equipment Grounding
A solar array produces 480 volts at 15 amps. Its power output is approximately this.
7,200 watts
This company developed the first practical silicon solar cell.
Bell Labs
Solar energy is considered this type of energy source because it is naturally replenished.
renewable energy
This condition occurs when nearby trees, chimneys, or buildings block sunlight and reduce energy production.
Shading
This NEC article primarily covers photovoltaic systems.
Article 690
An installer has eight 40-volt, 10-amp solar panels. The customer wants a higher-voltage array without increasing current. How should the panels be connected?
in series
