How big is a 200 watt solar panel?
You can refer to the size of those five 200w solar panels above Sungold, which vary in size on the market.
The physical dimensions of a 200-watt solar panel can vary based on the specific manufacturer and design. However, as a general guideline, a standard 200-watt solar panel typically measures around 1.5 meters (about 59 inches) in length and about 1 meter (about 39 inches) in width. These dimensions are approximate and can vary slightly between different brands and models.
How many amps 200 watt solar panel？
The number of amps produced by a 200-watt solar panel depends on the voltage of the panel. The relationship between power (in watts), current (in amps), and voltage (in volts) is described by the formula: Power (W) = Current (A) × Voltage (V).
Assuming the solar panel operates at a standard voltage of 12 volts (common for many RV systems):
200 watts = Current (A) × 12 volts
Solving for current (A):
Current (A) = 200 watts / 12 volts ≈ 16.67 amps
So, a 200-watt solar panel operating at 12 volts can produce approximately 16.67 amps of current.

Can I mix 100 watt and 200 watt solar panels？
Yes, you can mix different wattage solar panels, such as using both 100-watt and 200-watt panels in the same solar system. However, there are a few important considerations to keep in mind:
Voltage Compatibility: Make sure that the voltage ratings of the panels are compatible. Panels with different wattages might have slightly different voltage outputs, but they should fall within a similar range. Mixing panels with significantly different voltage outputs can lead to inefficient power production and potential damage to the panels or other components in the system.
Parallel or Series Connection: Solar panels can be connected in parallel or series configurations. Parallel connections maintain the voltage while increasing the current capacity, while series connections increase the voltage while maintaining the current capacity. When mixing different wattages, consider how you’re connecting the panels and how it will affect the overall performance of the system.
Current Mismatch: Panels with different wattages will have different current outputs. When connected in parallel, the panels will contribute their currents, so the panel with the lowest current output might limit the overall current capacity of the system. This could potentially affect the system’s efficiency and power production.
