Don, PV:WATTS version 1 is easiest to use and it is available at _http://rredc.nrel.gov/solar/calculators/PVWATTS/version1/_ (http://rredc.nrel.gov/solar/calculators/PVWATTS/version1/) . It covers fixed tilt, single- and two-axis tracking for standard crystalline silicon modules. My confusion had to do with whether the 5.9 kWh/m2/day was a fixed tilt value or single-axis tracker. Not knowing the location makes that impossible to figure out. PV:WATTS version 2 is what the CSI program uses to calculate EPBB rebate. Unfortunately, the EPBB calculator does not access the single- and two-axis tracking parts of PV:WATTS version 2. PVSYST is available online from Switzerland at _www.pvsyst.com_ (http://www.pvsyst.com/) Bill. Thanks Bill, I use PV WATTS routinely. I see they want a bit of $ for PVSYST so I need to think about that one. I agree that backing out the numbers from the given info is tough without more detailed site data.
