DC (Direct Current) → is the power generated by the solar photovoltaic (PV) modules. Panels are rated in kWp (kilowatt-peak), which is their maximum capacity under standard test conditions. AC (Alternating Current) → is the usable power output delivered by the solar inverter after converting DC into AC. Inverters are rated in kWac (kilowatts AC).
The DC and AC Ratio (also called Inverter Loading Ratio – ILR) is the ratio between the total installed DC capacity of solar panels and the AC capacity of the inverter. For example, if a solar plant has 10 MWp DC capacity and an 8 MW AC inverter, the ratio is 1.25. Q2. Why is DC and AC Ratio important in solar projects?
Some key points about current for solar panels: Short Circuit Current (Isc): The maximum current your panel can produce in perfect conditions. Maximum Power Current (Imp): The current at your panel''s most efficient operating point. You''ll notice that solar panels are rated in watts. That''s a very basic combination of the voltage and current.
Solar panels receive their ratings under specific testing conditions known as “Standard Testing Conditions” or “STCs”. These conditions serve as the industry standard for evaluating solar panels, making it easier to compare panels accurately. STCs replicate ideal operating conditions, including: And a “Solar Cell Temperature” of 25°C.
