Research & Articles
SolarPro Article on Wire Losses
An article published in SolarPro which analyzed wiring losses, finding that standard conventions can be too conservative, particularly for high DC-to-AC ratio designs.
SolarPro Article on Shading Losses
An article published in SolarPro which analyzed shading losses from obstructions, finding that modest array shading can be economically optimal under the right conditions.
Wiring Optimization (SPI)
Results from an optimization analysis to find the lowest-cost method for DC conductor design. We found that it was possible to reduce DC conductor cost by 27% through optimization.
SolarPro Article on Module Binning
An article published in SolarPro where the team at Folsom Labs analyzed the mismatch losses from module binning, and found that they were lower than most engineers expect.
String Inverter Yield Benefits
A white paper analyzing the yield benefits of string-level MPPT versus central inverter MPPT. String MPPT can provide a 1-1.5% improvement in system energy yield for shaded arrays.
IEEE Paper on Statistical Mismatch Effects
A paper selected for inclusion in the 39th IEEE PV Specialists' Conference, where we analyzed the system energy effects of statistical sources of module mismatch.
