Solar Panel

• Typically measured in Watts (W), with common sizes ranging from 50W to 400W per panel (larger panels can produce more power).

Efficiency:

• 15% to 22% efficiency for converting sunlight into electricity. Higher efficiency panels tend to be more expensive but provide more power in a smaller area.

Operating Voltage:

• 18V to 24V (for standard 12V or 24V systems) depending on the panel’s size and design.

Open Circuit Voltage (Voc):

• Typically 21V to 40V depending on the panel’s configuration.

Short Circuit Current (Isc):

• Typically ranges from 2A to 10A depending on the panel size and wattage.

Temperature Coefficient:

• The panel’s efficiency decreases with temperature. Common temperature coefficients are -0.4% to -0.5% per °C increase in temperature above 25°C.

Size:

• Common sizes for monocrystalline and polycrystalline panels range from 1.6m x 1m to 1.7m x 1.0m.

Weight:

• Typically between 15kg to 30kg per panel, depending on the material and size.

Materials:

• Monocrystalline silicon: Higher efficiency but more expensive.
• Polycrystalline silicon: Slightly lower efficiency but more affordable.
• Thin-film: Lightweight and flexible, but generally lower efficiency.
