• 🌞 Typical Electrical Specifications (STC – Standard Test Conditions)

• These values are from common 200 W solar panels on the market:

• Parameter Typical Value

• Maximum Power (Pmax) 200 W

• Voltage at Pmax (Vmp) ~18–21 V

• Current at Pmax (Imp) ~9.6–11 A

• Open-Circuit Voltage (Voc) ~22–26 V

• Short-Circuit Current (Isc) ~10–12 A

• Module Efficiency ~18–25 % (varies by cell tech)

• Power Tolerance ~0 % to +5 %

• Maximum System Voltage ~600–1000 VDC

• Temperature Range ~-40 °C to +85 °C

• Operating Conditions Standard Test Conditions (1000 W/m², 25 °C)

• 
  

• ✔ Notes:

• • A panel’s rated 200 W output is under ideal lab conditions (STC). Real-world output varies with sun angle, temperature, and shading.

• • Higher voltages (~30-35 V) are seen on some panels designed for 24 V systems, while ~18–21 V is common for 12 V battery charging.
