True/False: A solar panel has no moving mechanical parts.

True/False: A solar panel is less efficient in the summer.

What is the most common solar panel used by IWS?

Which panel is reinforced to reduce microfractures?

Which panel has the highest wattage and highest efficiency rating?

What is the most common type of solar system IWS installs (over 90% of business)?

What type of system would you recommend to someone that can’t, or doesn’t want to, be connected to the grid?

What type of system would you recommend to someone that wants to have backup power if the grid goes down?

What type of system would you recommend to someone that only wants to eliminate their power bill?

Which system is the most affordable?

The following are viable options for backup power when the grid goes down:

Which of the following is a description of what it means to be “off-grid”.

True/False: The SMA inverter can provide power to one outlet when the grid goes down and the sun is shining.

True/False: While the grid is working, a hybrid system works just like a grid tied system.

True/False: A grid tied system will produce power for the home when the grid goes down, but only during the daytime.

What direction is optimal for solar panels?

The ideal position of a roof is one that faces due 
NorthSouthEastWest

True/False: IWS will always tilt the panels on the roof to ensure they are perpendicular to the sun for maximum efficiency.

Which of the following components are necessary when installing a solar mounting system?

IWS can install Solar on the following roof types:

True/False: If plastic sewer exhaust vents are in the way, they can be cut down and installed over.

Flat roofs are usually installed with the following type of mounting system:

If there is not enough south facing roof space, the panels can be mounted on the roof in the following direction(s):

True/False: Inverters are necessary because solar panels produce AC power and a home uses DC power.

Power runs from the solar panels, to the inverter, and then to the:

If one solar panels is shaded on a string inverter, then the other panels:

If batteries are going to be used, you must use the following type of inverter:

True/False: On a string inverter, panels on the same string need to be facing the same direction.

Which of the following inverters are the least expensive?

Which inverter offers a one outlet secure power supply that works when the grid goes down and the sun is up?

True/False: Micro-inverters allow panels to run independently from each other. Shading on one will not affect any of the others.

True/False: Enphase allows for individual panel production monitoring of the panels.

True/False: Panels with a micro-inverter need to be facing the same direction to be fully efficient.

The following needs to be done for a micro-inverter to be hooked up to backup power:

True/False: With the Enphase Envoy system, the solar installer can monitor each panels production individually and in real time.

Which type of inverter uses a DC optimizer to individually monitor panel production on a string inverter?

Which system combines the string inverter advantage of being able to add batteries with the micro-inverter advantage of individual panel monitoring?

True/False: Wiring from the panels to the inverter and meter will go through the attic and down through the soffit to the outside, or through the attic and down through the garage ceiling if in the garage.

True/False: Kilowatts are a measurement of how much power is being used in the home.

In northern Utah, 1 kW will produce ___________ kWh per month facing due south in northern Utah.

How many kWh will a 4 kW system produce per month?

On average, how many kWh will be produced with a $160 per month power bill (rounded up)?_______________

What size of a system will be needed to cover a $150 per month power bill? ________________

True/False: Installing a "net-meter" will provide backup power to one outlet.

Approximately how many panels would a system need to replace a power bill of $90 (rounded up)?

Approximately how many panels would a system need to replace a power bill of $190 (rounded up)?

If a power bill is less than $150 per month, what is the estimated kWh rate they would be charged?

If a power bill is more than $150 per month, what is the estimated kWh rate they would be charged?

What is the multiplier used to convert estimated kWh to estimated kilowatts?

What information would you collect to give an official bid instead of simply an estimate?

If a customer is paying a $100 dollar per month power bill today, what would their total cost of energy be in 25 years if rates continued to rise 5% annually?

If a customer is paying a $100 dollar per month power bill today, what would their total cost of energy be in 25 years if they went solar (after incentives)?

True/False: A customer that goes solar will pay and average of $0.06 per kWh over 25 years. If rates continue to rise 5% annually, a customer will pay an average of $0.21 per kWh by continuing to rent from a utility company

True/False: Energy costs have risen dramatically and have nearly doubled as a fraction of family budgets since 2001.

Will a solar system still work if the power grid goes down?

True/False: Panels can be added to a system after it is installed simply and inexpensively.
