GRADED A+| ||PROFESSOR VERIFIED|| ||BRANDNEW!!!||
A system that sits on a flat/low slope rooftop and has no
penetrations is called a:
A) Flush mounted system
B) Flashed system
C) BIPV system
D) Ballasted system - ANSWER-Ballasted systems are common
flat low slope roof systems that are not penetrating the roof. A
ballast is something that is relatively heavy keeps the PV from
blowing away
Proper slope for an extension ladder? - ANSWER-1:4
The primary source for a utility interactive PV system is the:
A) Inverter
B) Utility
C) PV
,2|Page
D) Charge controller - ANSWER-Utility. The interactive inverter
will match the voltage and frequency of the utility
What is specified on a charge controller?
A) Irradiance limit
B) Insolation limit
C) Maximum voltage
D) Minimum current - ANSWER-A charge controller will have
maximum voltage specified (and so will most any equipment). A
charge controller will also specify maximum current
Units for irradiance - ANSWER-Irradiance is power per area,
usually measured in watts per square meter. 1000W/m^2 is the
irradiance level called Peak sun, or irradiance at STC. Energy per
area is irradiation or insolation.
What is used to calculate maximum system voltage? - ANSWER-
Temperature is used to calculate maximum system voltage along
with Voc, the temperature coeffient of Voc and the number of PV
modules connected in series.

What will be increased by reflective surfaces (albedo)? -
ANSWER-Current. Reflections and increased light increases
current.
What is the best voltage for charging a 12V lead-acid battery?
A) 12V
B) 11.8V
C) 12.3V
D) 14.1V - ANSWER-14.1 .
Best voltage for charging a 12V battery is 14.1V (best of the
choices given). A 12V lead-acid battery will sit charged at
12.6V and often charge somewhere between 14 and 15V. If a
12V lead-acid battery is at 50% depth of discharge, it will
measure about 12V
Unit for resistance - ANSWER-Ohms
Wind uplift forces in the construction industry in the US are
measured in... - ANSWER-Pounds per square foot (psf)
, 4|Page
Direction on a compass is - ANSWER-Azimuth
Hydraulic analogy for voltage is - ANSWER-Pressure. Current is
flow
Which room cannot have a PV dc disconnect?
A) Kitchen
B) Attic
C) Bathroom
D) Bedroom - ANSWER-Bathroom. PV dc disconnect not allowed
in bathroom (think wet feet)
Stand-alone inverter output goes to: - ANSWER-Loads. Off-grid
inverter output goes to loads. Loads are what use electricity
Best sealant for residential rooftop - ANSWER-Polyurethane and
silicone are the best. Silicone is a sealant, silicon is what solar
cells are made of
