That was expected, …. with centralized utility, people just receive power wire at home, so they are completely disconnected from the basic understanding of how power is generated and the units involved in the system. Solar panels with batteries are going to change that, it just requires time.
While I'm unsure if this would be a good idea, perhaps using non-standard units such as $/month/m2 to quantify the roof value could engage the general public more with PV systems.
Let's consider a scenario: in a state with an average electricity rate of 0.1$/kWh, 1000 W panels with a surface area of 5.6m2 typically producing 1200 kWh a year, result in $120 savings annually or $10 per month. This translates to a solar potential of 1.78$/month/m2 (10$/5.6m2), rounded to 2$/month/m2 for simplicity.
We could communicate to individuals that in their specific location, they can save $2 per month for every square meter of roof. For example, if they have 50m2, they could save $100/month.
If the electricity rate is double at 0.2$/kWh in another state with similar insolation, the potential savings there become 4$/month/m2 or $200/month for a 50 m2 roof.
Talking about money and roof space instead of kilowatts may get people to picture quickly the size / value of their PV system.

Now, if we can just get 95% of the USA public to know the difference between a KW and a KWH, we might be able to make better progress./s
When I run into people and solar comes up, I always ask, "DO you know how many KW's your roof array is?" Unfortunately, the vast majority do not know. They just know their elect bill went down..... go figure....

Thank you Prof. Keith for including PVWatts in the list.
This is really a user-friendly tool, .....just write the location address, and in 1-2 clicks, it provides how many kilowatt-hours of energy the default solar PV system will produce monthly. Thanks.

Elias,
You probably know about PVWatts, also. I wouldn't be surprised if the tools you listed incorporate PVWatts for their calculations. The thing I like about PVWatts is that it is so simple - just pick a location and enter a few inputs.
Best,
Keith
