PV Fundamentals
Start here before system sizing and software simulation.
PV Modules
Learn power rating, Voc, Vmp, Isc, Imp, temperature coefficients, efficiency and module protection concepts.
Strings & MPPT
A string is a series connection of modules. String voltage must remain within the inverter's MPPT and maximum DC-voltage limits across operating temperatures.
Inverters
Understand DC input limits, MPPT windows, maximum current, AC output and DC/AC ratio.
Losses
Soiling, temperature, mismatch, wiring, inverter and availability losses all affect yield.
Orientation & Tilt
Azimuth, tilt, shading and row spacing influence irradiation and energy yield.
Design Sequence
Site → load → resource → module/inverter → stringing → layout → electrical design → simulation → documentation.
