[Equest-users] PV results

[John T. Forester]

Juan,

Here is some text from a SIM report summary with notes on how energy is accounted.  This might help you with determining the savings from PV.

Generators and PV:
The BEPS report only includes energy drawn or supplied across the building boundary.  Energy provided by generators or PV is not included in the BEPS report unless it “flows” through a utility meter (e.g., is supplied back to the utility grid).  BEPS does not report energy used within the building.  Rather, BEPS reports energy “imported” into or “exported” from the building.  PS-E reports energy use within the building, i.e., includes energy imported from the utility grid and provided by any on-site generators and PV.

I have.

For PV studies I typically build the rest of the model first, save a separate copy, then define the PV equipment and compare the two sets of results for overall figures.

For a more detailed look at the modeled results, explore the variety of custom hourly report options under “photovoltaic module.”

Has anyone started incorporating a photovoltaic electric generator into your models?  where do you view the effect of the electric generator on the overall electrical consumption?
