Additional Information
Solar panels:
In general, the required solar panel output in Watt peak (Wp) must be 30% higher than the rated power of the installed pump(s). Also, to compensate for partly cloudy weather it is recommended to choose a larger panel size.
- The recommended panel size for model ZL 38-13N is 60 Wp.
- The recommended panel size for model ZL 50-20N is 100 Wp or 2 * 80 Wp panels for the ZL 50-20N 35 V version (in series).
If you buy more panels make sure to buy identical panels (same brand, same features). Note that the power (Watt) indicated on a panel is often less than the real output in Watt. If more brands of panels are available, find the most effective panel by testing several brands with the same pump configuration and compare head or flow. The panels need to be close to the pump to prevent losses in cables and high cable costs. Make sure the panel(s) are fixed securely on a panel stand so nobody can steal them or, if the customer wants, make them removable so they can be stored in house at night.
