Self-consumption Calculation with HH data

[haydn]

Hello,

If I import HH data into PVSol, does it use this when calculating self-consumption with an hourly simulation, or does it add the 2 HHs together and use hourly data?

Further to the above, is the formula used to calculate self-consumption % simply 'if consumption is greater than PV output then 100%, if not then = consumption/pv output'? This would essentially assume that PV output and site demand is completely flat for each simulation period.

Thanks,

Haydn

Dear Haydn,

Thank you for your inquiry.

If you select multiple load profiles (whether imported by you or built into the program), they are aggregated into a total consumption figure for the simulation.

In the hourly simulation, the self-consumption share is calculated for every hour of the year by determining what percentage of consumption can be covered by PV energy.

Hourly simulation is the standard. However, when importing load profiles, you can also import data with 1-, 5-, 10-, 15-, or 30-minute intervals and then run the simulation on a minute-by-minute basis to obtain more precise results.
