Error running simulation

This is my first time using the application, so, this is likely user error. But all of the fields that seem to require input have it. When I try to run a simulation, it fails with:
exec fail(pvsamv1): CEC 6 parameter model: Could not solve for normalized coefficients. Please check your inputs.
Simulation pvsamv1 failed.
SSC requires input ‘gen’, but was not found in the SAM UI or from previous simulations
Simulation utilityrate5 failed.
SSC requires input ‘annual_energy_value’, but was not found in the SAM UI or from previous simulations

Possible bug with net billing

I'm wondering if there's a bug in net billing.

I'm trying to verify that SAM is modeling my electricity bill correctly, but I haven't been successful yet. Particularly I'm seeing surprising results with the monthly "Excess generation credit $ earned" value. I thought I could verify that the credit $ earned is being calculated correctly by comparing it to "Excess generation kWh credit earned" x sell rate, and indeed it matches perfectly, for any month in which "Electricity to/from grid" is negative, but not if it's positive. See the attached screenshot.

LCOE inconsistency, Cash Flow

Hi, I'm simulating a 100 MW central receiver CSP plant (without TES). In the "Summary" of results, SAM tells me that the resulting nominal LCOE is 26.02 cents / kwh, which coincides with the information shown in the "Cash Flow" tab. However, if I check the detail of the cash flow with the "Send to Excel with Equations" tool, it turns out that the nominal LCOE shown is 29.44 cents / kwh.

Weekend Electricity Rates are ignored

The weekend Electricity Rates do not appear to be used in the simulation results. In the attached screenshot, no matter how I structure the Weekend #1 and #2 periods, the estimated yearly electricity bill remains the same. I.E. I can make everything "2" or everything "1" with no observable differences in the simulation output. Modifying the Weekday periods, however, does have an affect, as expected.

Cell Type enum ordering mismatch

We are writing some custom wrappers around both the pvsamv1 and iec61853par modules, but are seeing a mismatch in the ordering of enum options between the two when using the SAM UI and the SSC SDKTool.

The enum for iec61853par has CdTe as the fifth option, but the SAM UI for the IEC61853 Single Diode Model option has CdTe listed third.

In addition, the only field in the SDK Tool that calls out the enum also has a different order (see below).
