1During the initial customer consultation, what is the MOST important document to request for accurately sizing a residential PV system?

A.The customer's home insurance policy

B.12 months of utility bills showing energy consumption

C.The original architectural blueprints of the home

D.The customer's federal tax return

Explanation: Twelve months of utility bills provide the most accurate picture of annual energy consumption patterns, including seasonal variations, which is essential for properly sizing a PV system. Without this data, the sales professional cannot determine the appropriate system size to offset the customer's actual usage. Exam tip: Always request a full year of bills to capture heating and cooling season differences.

2A residential customer uses 10,800 kWh per year. What is their average monthly energy consumption?

A.1,080 kWh

B.900 kWh

C.1,200 kWh

D.800 kWh

Explanation: Average monthly consumption is calculated by dividing annual usage by 12 months: 10,800 kWh / 12 = 900 kWh per month. This is a fundamental calculation in the qualifying process to understand baseline energy needs. Exam tip: Be prepared for simple arithmetic questions that test your ability to convert between annual, monthly, and daily energy figures.

3Which utility rate structure charges higher rates as a customer's energy consumption increases within a billing period?

A.Flat rate structure

B.Time-of-use (TOU) rate structure

C.Tiered (inclining block) rate structure

D.Demand charge rate structure

Explanation: A tiered or inclining block rate structure charges progressively higher rates per kWh as consumption increases through defined usage tiers. This structure makes solar particularly attractive because the system offsets the most expensive electricity first. Exam tip: Customers on tiered rates often see greater savings from solar because they avoid the highest-cost tiers.

4A customer is on a time-of-use (TOU) rate schedule. When are electricity rates typically HIGHEST?

A.Early morning hours (5-7 AM)

B.Late morning to early afternoon (10 AM - 1 PM)

C.Late afternoon to evening hours (4-9 PM)

D.Overnight hours (11 PM - 5 AM)

Explanation: TOU rates are typically highest during peak demand periods, which in most utility territories occur during late afternoon to evening hours (approximately 4-9 PM) when residential demand surges from air conditioning, cooking, and returning home from work. This peak period often does not coincide with peak solar production. Exam tip: Understanding TOU peak windows is critical because it affects the value proposition of solar and may support adding battery storage.

5What does net metering allow a solar PV system owner to do?

A.Sell all electricity produced directly to the wholesale energy market

B.Receive credit on their utility bill for excess electricity exported to the grid

C.Disconnect entirely from the utility grid without penalty

D.Avoid paying any fixed charges on their utility bill

Explanation: Net metering is a billing mechanism that credits solar system owners for the excess electricity they export to the grid. The customer's meter effectively runs backward when their system produces more than they consume, and they receive a credit (often at the full retail rate) against their future electricity consumption. Exam tip: Net metering policies vary significantly by state and utility; always verify the current policy for the customer's jurisdiction.

6A customer asks about the difference between net metering and net billing. Which statement is correct?

A.They are identical billing mechanisms with different names

B.Net billing always credits exported energy at a lower rate than the retail rate

C.Net metering only applies to commercial customers

D.Net billing requires battery storage to participate

Explanation: Under net billing (sometimes called net billing tariff or NEM 3.0 in California), exported solar energy is credited at a lower rate than the retail rate, often based on the avoided cost or wholesale rate. This differs from traditional net metering where exports are credited at the full retail rate. Exam tip: The shift from net metering to net billing in many states increases the value proposition of battery storage since self-consumption becomes more financially advantageous.

7When qualifying a commercial prospect, which factor is MOST important for determining the financial viability of a PV system?

A.The color of the building's roof

B.The business owner's personal credit score

C.The facility's demand charges and overall electricity costs

D.The number of employees in the building

Explanation: For commercial customers, electricity costs including demand charges are the primary driver of PV system financial viability. Commercial rate structures often include significant demand charges based on peak power consumption, and understanding total electricity costs helps determine potential savings and return on investment. Exam tip: Commercial facilities with high demand charges may benefit from solar combined with battery storage to reduce both energy and demand charges.

8What is a demand charge on a commercial electricity bill?

A.A charge based on total energy consumed during the billing period

B.A charge based on the highest rate of power consumption (kW) during a specific interval in the billing period

C.A flat monthly service fee charged to all commercial accounts

D.A penalty for exceeding the contracted energy supply

Explanation: A demand charge is based on the customer's peak power draw (measured in kW) during a specific interval (typically 15 minutes) within the billing period. It reflects the utility's cost to maintain infrastructure capable of meeting peak demand. Solar alone may not reduce demand charges significantly unless paired with storage. Exam tip: Demand charges can represent 30-50% of a commercial customer's bill, so always analyze them separately from energy (kWh) charges.

9A homeowner mentions they plan to sell their house within 2 years. How should the sales professional address this?

A.Recommend the largest system possible to maximize the home's resale value

B.Decline to offer solar since the payback period exceeds 2 years

C.Discuss how solar can increase home value and present lease or PPA options that may transfer to the new owner

D.Suggest the customer wait until after selling the house

Explanation: When a customer plans to sell soon, the sales professional should discuss how solar adds value to the home (studies show homes with owned solar sell for a premium) and present financing options like leases or PPAs that may include transfer provisions. This addresses the customer's concern while still presenting viable options. Exam tip: According to studies, homes with solar sell faster and for approximately 4% more than comparable homes without solar.

10Which question is MOST critical to ask early in the qualifying process to determine if a prospect is suitable for rooftop solar?

A.What brand of appliances do you use?

B.Do you own or rent your home?

C.What color would you like the panels to be?

D.Have you ever visited a solar farm?

Explanation: Establishing property ownership is fundamental because renters typically cannot install rooftop solar systems on property they do not own. This is a basic qualifying question that determines whether to proceed with a rooftop proposal or explore community solar alternatives. Exam tip: Always confirm ownership early to avoid investing time in a prospect who lacks the authority to modify the property.
