To get there, use the following formulas; 1 Amp AC = 10 Amps DC. (example, 2AC amps =20DC amp) Add 10% (22 amps) DC amps x 12v = DC watts. (22 x12 =264 watts) 264 would be entered in field # 3. This equation shows that power (watts) is the product of current (amps) and voltage (volts). Purpose: It helps solar energy professionals and DIYers calculate the wattage of solar panels for system design and analysis. Rule of thumb DoD: LiFePO₄ ≈ 80–90%, AGM ≈ 50%. Array Watts ≈ Daily kWh ÷ (Sun Hours × System Derate). Result shows. . If you are using an DC to AC power inverter, meaning your device is rated in AC amps and 110 V, you will need to convert that number into DC watts before entering it in the field. Then you will need to add about 10% due to the inefficiency of the power inverter. The voltage of solar panels is typically between 12 and 24V, and the current can be measured using a multimeter, usually ranging from 6 to 7.
