<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">I agree with Nick that an outside software tool should be used. RETScreen is a very good tool, however, it will give you annual production totals. Another
approach is to use an online tool such as PV Watts. It requires minimal inputs and you can download hourly production numbers. These could be dropped into an hourly report spreadsheet along with time of use rates to obtain the net hourly electricity used
or exported as well as cost. The value of each kWh exported might be valued differently. You could also use the hourly spreadsheet to calculate the peak demand offset monthly from PV generation.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">I think the basic procedure is you use your EAc1 energy model’s final cost and consumption figures to work out the averaged “rate” for electricity (LEED-2009
EAp2 templates assemble this algebra towards the end, can’t recall if the 2.2 templates do the same), and that figure is used to work out the value of the savings accounted under EAc2. I would start with the EAc2 template and documentation so far as the overall
procedure is concerned.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">That said, from my (limited) experience and the input of others on this list, PV can be explicitly modeled within eQuest model but is probably most easily approached
if you start with some outside task-specific software to determine the amount of power you expect to be generated. This gives you something to calibrate against without earning a PhD in photovoltaic minutiae. Kinda similar to geothermal well fields in that
regard. I think the RETscreen spreadsheets are among of the series of tools that have been suggested to this end (more in the archives). <u></u><u></u></span></p>
