GOSED Solar Rates Model Error in Calcs #300

Closed drdanley closed 9 years ago

drdanley commented 9 years ago

Created a new "Rates" model using data from Form 7 that was supplied to me. Published this as "drd solar rates test 3feb15" so you can see it.

In the “Monthly Data Table” for month ‘0’, “Generation” is 625,000 Wh. I assume that this is generation from a single system, which the model specifies as 5 kWp-DC.
“Total Generation (kWh)” (which I assume means system wide solar generation) should be # of customers * %Solar * SolarGeneration, so, for January: 46,688customers_0.05_625,000Wh/1,000kWh/Wh = 1,459,000 kWh The table lists 145,900,000 kWh, which is off by a factor of 100. I suspect this is because of confusion with whether the input field "Residential Customers With Solar (%)" should be entered as 5% or 0.05. When I enter as ‘0.05’, the number is calculated correctly.

Action required: Clarify whether the number enter into "Residential Customers With Solar (%)" should be entered as a percent or a decimal.

Sorry, this is for Solar Rates model.

"Residential Customers With Solar (%)" -- 5 in that input corresponds to 5% of customers having solar. We need to standardize on this everywhere and give a clear message to users about it.

Thanks Doug.

Mannan, this is a priority after the 6 prototypes are complete.

Corrected. Clarification added to the tooltip so a value of "five percent" is entered as a "5". Working on implementing consistent functionality on solarFinancial, so that we have similar results :)
