To determine if the 70Wp solar panel is sufficient to run the 60W pump, we need to consider a few factors.
The 70Wp solar panel has a maximum power output of 70 watts. This value represents the maximum power the panel can generate under ideal conditions. However, the actual power output may vary depending on factors such as sunlight intensity, panel orientation, shading, and efficiency losses.
The pump’s power requirement is 60 watts. If the solar panel can consistently provide 60 watts or more, it should be sufficient to run the pump. However, keep in mind that you might experience some power fluctuations due to varying sunlight conditions, which could impact the pump’s performance.
Now, let’s look at the electrical specifications of the solar panel:
- Open circuit voltage (Voc): 21.2V
- Short circuit current (Isc): 4.34A
- Maximum power voltage (Vmp): 17.8V
- Maximum power current (Imp): 3.93A
The voltage and current values provided indicate the operating range of the solar panel under different conditions. The maximum power point (MPP) occurs at the Vmp and Imp values. In this case, the maximum power point is approximately 70W (Vmp * Imp = 17.8V * 3.93A = 70.154W).
Based on the specifications you provided, the 70Wp solar panel should be sufficient to run the 60W pump. However, it’s worth noting that the pump’s power requirement is close to the maximum power output of the panel, which means it might not operate at full power continuously, especially if there are efficiency losses or lower sunlight intensity.
Regarding the converter, you mentioned that you want to run the pump directly from the solar panel without using a battery. In that case, you won’t need a converter, as long as the pump can operate at the 12V output provided by the solar panel. The voltage output of the solar panel should be compatible with the pump’s voltage requirement.
It’s important to ensure proper wiring and connections between the solar panel and the pump, following the manufacturer’s instructions for the pump’s electrical connections.
