Hi, I’m wondering why the solver dispatches fuel generators and curtails PV even when total PV generation exceeds demand. Generators startup and shutdown costs are set to zero, fuel cost is higher than PV (which has zer…

How can I scale all my PV generators nameplate capacity by a certain percentage all at once? Must I create an event for each one? Do I need to group them somehow? thanks!

Why are my results showing solar generation at night? I have already checked that the start time of my resource data lines up. Both my data and my simulation start at the first of the year at midnight. There is no sol…

Is LOSSES\[%\] the correct place to enter solar efficiency? the field description mentions this value is only used when the weather data is retrieved from a weather source (not my case).. Does this mean the value entered h…

## [Does the ENET 39 network come with standard solar irradiance data, or does it assume a capacity factor of 1 if no irradiance data is fed?](https://forum.encoord.com/t/does-the-enet-39-network-come-with-standard-solar-irradiance-data-or-does-it-assume-a-capacity-factor-of-1-if-no-irradiance-data-is-fed/325)

If irradiance data needs to be fed, is there a tutorial for that?

I wrote a simple script to model solar irradiance on the lunar surface at the equator. The output is a CSV file with two columns, time (hours of simulation) and capacity factor (unitless value between 0 and 1). Is this …
